Preparation

We started working on the cars shortly after finishing with Cal Speedway in March. David's Laser, the one that we found in Las Vegas the 1st of the year, had a turbo, that was shot. So we pulled the setup off my car and installed it on his. Meanwhile I ordered a Big 16 G, an EVO, manifold, O2 housing, a 2G maf, and 660 injectors. I spent some time porting everything with some input from Bruce, "Oldman". (Thanks a bunch Bruce!):thumb: I got mine put back together with a week or so to go. Starting on the Sunday before the event weekend, I started to dial in the new equipment and in the middle of this we discovered I had some P/S fluid on the floor. All the connections looked good and it took a couple of minutes to discover, that the variable steering, grounding plug had completely blown out of the pump. So on Monday we ordered a new plug. It took till Thursday to arrive, but in the meantime I plugged the hole and tried to do some more tuning on Tuesday. Unfortunately it was still leaking quite a bit, so I didn't get much, dialing in, done. On Wednesday, I tried again to do some dialing in, without much success. Thursday the grounding plug came in and I replaced it and was able to dial things in, well enough to get started on the track. Everything was good!!!

The Day Before

When I got to the shop on Friday morning, to pick up my car and load up. I was informed by David, that my car was leaking P/S fluid again. Upon inspection, the brand new grounding plug, that I had just put in the night before, was again (2nd time) missing from the front of the P/S pump :cry: . So I debated whether to order up a complete new pump or call off the weekend, for my car. Well, I decided it had to be the pump at this point, and made the decision to go ahead and install a new one. We ordered one up, it came in, within the hour, and I got it put on. I got all the essentials assembled and loaded up about 5:30. As we were getting David's car loaded up, I tripped over the front rail of the trailer, fell backwards, and damn near broke my leg. It got caught up in the tongue of the trailer, with my leg ending up as a lever and the tongue of the trailer as a fulcrum. We finished by 6:30 or so and didn't end up getting away for Willow till about 8:00 PM. I had planned on being there by 1:00 PM that day, to get teched and set up the tent, etc. Anyway, we got to the track a little before 11:00 PM (Track closes the gate at 11:00) and only had time to drop the cars off, unloaded the truck, and head for the hotel.

Track Day "Saturday"

We got up early on Sat. and were at the track gate waiting at 6:30AM. We needed to tech both cars. I pulled my car off the trailer and I heard a sound I'd been hearing, off and on, since the Sunday before. The groan of a power steering pump low of fluid. Yep there was a puddle of P/S fluid on the trailer floor and upon further inspection, there was no grounding plug to be found anywhere, including it's niche in the front of the P/S pump :mad: :coy: :cry: :sosad: . (This was the 3rd one to be spat out of two different pumps). Well this was a new one for me, being broke before I could get the car off the trailer. I must be going for some kind of record here!!! David and I decided it must be the rack I replaced at the 1st of the year, or a plugged P/S hose, or the like. With the grounding plug being a special order item, even if it turned out to be a hose, I was dead in the water at this point. Later that day, Mike Welch was over at the Horse Thief Mile and I went over to talk with him about the situation. RRE was there doing a film shoot of some sort . Anyway, I asked him about the problem I was having and he told me he had never seen anything like it, before. We discussed it for some time and, both agreed that it had to be an enormous amount of pressure that could shoot that plug out with the force of a 22 cal. pistol round.

Directing our efforts to David's car

So we got David's car up and going, teched, and he prepared to make his 1st ever track run in the car. Things were looking good as he made his way around the 9 corners of Willow Springs big track. There were a number of pretty quick cars there, several Porsches and the like. As Ginger and I were pulling back into the pits, after circling the perimeter of the track, taking pictures, David and his instructor were talking inside David's car and I noticed some smoke coming from his car. It looked like it was probably brake smoke, but nothing was going to be that easy this weekend. When he made his way back to our pit, and I popped the hood, it was apparent. There was coolant everywhere. He went for his post session meeting and I took a look at the car. I found the 90 degree rubber hose connecting the two metal coolant lines for the turbo, had erupted with a huge crack. I pulled the one off my car and found some small cracks in mine also. So I borrowed some soft braid line (from an SU/Trans Am Mustang friend) and got it all connected back up. We put water back in, cranked it up, and discovered that the waterpump was now leaking. So off we go to find a parts store that had a pump, found one, picked it up, and back to the track we went. We spent the afternoon exchanging the water pump out. We got everything back together, and the engine timed, about the time, the evening enduro was starting up. Well, we put water back in and checked for leaks and there was a dribble coming from the area behind exhaust manifold. We couldn't see exactly were it was coming from, so we filled it back up with water and turned over the engine.The coolant shot out with great force from behind the exhaust manifold, and there was the distinct sound of a cylinder laboring. It's a head gasket we were pretty sure.

So that was it, for our weekend. We went out to eat that night and got back to the track about 9:00 AM the next morning, loaded my car, winched Dave's car back on his trailer, got everything else packed up and put back in order, and It was homeward bound.

Synopsis

David got some lap time in and really enjoyed it. I was at least, at the track enjoying myself, a bad day at the track is still better than being at home doing chores.:D So it's on to another weekend of track time, most likely in July, and we energetically look forward to it.

As always, we thank everyone, for their efforts to keep us going. A special thanks to Dr Haiavy and Inland Cosmetic for his and their relenltless help. Allied Automotive, in Upland, for use of their facility and parts ordering etc. Also to David and Ginger, thanks for everything.

Man... when you think about all the energy and $ it takes, and something as simple as that happens you want to just scream :cry: The Big track at Willow Springs is incredible and is known to be one of the fastest road courses on the West coast. I know that even with the short amount of time David was on the track the pictures show that ear to ear grin we all get racing our cars.

You'll tear it up next time Tom... for sure :D
 
Man it seems like no matter what you do there's always some little thing you could have never planned on.

That leak on the manifold could easily be either the fitting at the coolant feed or the o-ring at the waterpump. I'd guess the latter as you had to replace the pump at the track. Hopefully all is well and you can be back and ready to go by the next event.

Your power steering issue does sound extremely strange and I'd have to imagine it's the result of some sort of blockage in the lines or rack causing an buildup of pressure to do something like that. I've never even had that fitting out of the ps pump but I'm guessing it screws in. If so you could try a little thread locker or even tig weld it back in once you get the blockage cleared just to make sure it never comes out again. Although it may be saving your pump and lines from further damage by acting as a power steering blow off valve of sorts.

I believe we did spend a fair chunk of change on the weekend, and I repayed one of my sponsors for the entry fees, but it's still, all worth it. It's just part of the process. Everytime I start to think differently, I just remember you telling me about your early times.:D

David, really did enjoy the weekend, even with the setbacks, and is biting at the bit, to get back out there.:thumb:

Thanks Greg, I know I'm going to give it (Willow Springs) ]all that I have, to give, in July, and hope for the best.
See you there. :thumb:

:)

Kyle, it seems like I'm seeing my fair share, or maybe a little more. :cry: :D

We thought about that and a freeze plug, but it's pointing toward the head or gasket. Water poured out the exhaust when we loaded the car on the trailer.

Kyle, the fitting does screw into the pump, but the threaded portion is not the part that is being blown out. It is the actual brass pin and it's respective plastic insulator that is being shot out of it's (crimped in??) position within that screw in, fitting.

Wow, what a frustrating weekend. That plug deal is one of the strangest dsm quirks I've ever heard of. Cool pics though.:rocks:

Thanks Jim, it was strange, though we tried to make the best of it.
We looked at both cars today, I'll throw some pixs up in a bit, of some of what we found.

:)

David's Engine: It was the head & gasket. The gasket was a composite and in bad shape. We measured the head and it will need decking.

My p/s blues:
The 1st pix shows the last pin to be ejected, and the order of the components behind the pin, the pin and the locking nut. The 2 arrows are pointing to the pin and the base for the pin that seperated and allowed the pin to be ejected out the front of the locking nut. (there looks to be a section of pin missing on this one)

2nd pix is a closer look.

3rd is what we did to alleviate the pin completely, we welded the screw to the locknut. The welded pixs didn't turn out.

I'm still unsure what else is going on, but we checked things out after replacing with the altered locking nut, and found a broken worm clamp that was allowing some air in the system. I replaced it and every thing looks good. The fluid is circulating and there doesn't seem to be any obstructions. We'll check it again over the next few days and see how things go.

Ok, correct me if I'm wrong, is that the sensor or switch that tells the ecu to increase the idle when steering? My car has had that disconnected since I got it & didn't seem to notice. Now the idle motors are all blocked off. :D I may make a plug like that to avoid such catastrophies from befalling my heap.

Yep, It raises the idle rpm under load. As I said above, I'm still not sure what the underlying poblem is- was - might be???? :D

I don't know enough specifically about power steering systems to be much help. :coy: I've got to think that maybe something in the valve body in the rack is creating pressure spikes or something like that.

Jim, I certainly coudn't disagree with you on your rack theory, it was reworked in Feb, but I had no problem with it, at the track in March. After seeing the last pin, up close, (seems to be a piece missing) I'm even considering some external force could be knocking it off it's pearch. The problem with that theory, is I cant imagine what could have come in contact with it:confused: . My thought regarding the original failure, was that we bumped it while putting the new alternator in at the track, in March. I just hope the elimination of the pin takes care of it, and as Kyle mentioned, I don't have any new problems associated with it, (ruptured lines etc.).

A follow up on my P/S woes:
After checking it a few times during the week, I'm still getting air in the system (or possibly unable to get it bled properly) for some reason :confused:. I plan on checking all the lines, cooler, and reservoir, for problems, and I ordered a new pump (#2), to replace the one that was installed the day before Willow Springs. If that doesn't do it then it's off with the previously replaced rack, and have it checked out. If we can get it resolved, early this week, I'll try to take the car to the SRT track day at the Horsetheif mile at Willow, next weekend and see about getting the new turbo/maft/exhaust setup dialed in.

Edit) Add: 5-28-06: Looks as if I was able to get the system bled today, with several hours of effort, but I think this pump is trashed. I'll install the new one when it comes in on Tuesday , and see how everything goes.
:)

I switched the P/S pump out and was able to bleed it ok, but when I put the car back on the ground (with the additional tire turning resistance) I still got the moan of a ? bad P/S pump, but it was another new one. So we started looking at the rack to see if it could possibly be leaking into the boots. Nope no leaks anywhere and all connections were tight. At this point, after several weeks, I'm racking my brain, to figure out what's going on, then it came to me. I'm embarrassed :coy: to say what it was!!! When we pulled the motor in Feb., we switched the lines on the P/S pump, so it fed the pump from the bottom of the reservoir. This was before Cal Speedway and we had no apparent problems there. I then switched them back to my original configuration and it was like night and day. I ran all day Saturday at Willow Springs (Horsethief Mile) with no problems at all. (I'll write this up when I get some time).

The pump doesn't seem to like, receiving the fluid via the cooler. I'm still not sure what the exact difference between the 2 configurations (see below), in regards to the problem is, but it certainly seems to have alliviated it. There could be a number of variables here, line size, height of the cooler, etc.

:)

Facinating. Maybe the pump is unable to draw uphill that far. Whooda guessed.
