I would hold off on the l 19 still later the arp set up will handle quite a bit. Worked for on several builds now.

I meant what I said , I'm gunna pound her out early so I can go work on the car

 

[92AWDHX40]

Sounds good.

How's the HG replacement coming along? Did u decide to keep the standard ARP's or not?

Hey guys, heads off.... what do you guys think about the exhaust valves.... white? Intake valves look fine

 

[donniekak]

You need a straight edge. After popping a gasket like that both the head and block may need milled.

Head and block were flat, Put a straight
Edge to them. I used a composite gasket also so I'm not worried

 

[donniekak]

How flat was it? Was it a real machinists straight edge? How did you clean off the old gasket material?

When replacing a blown headgasket 99% of the time the head needs resurfaced. Most of these blocks that haven't been resurfaced in 25 years are at least .002" out.

It's was a straight edge, not a machinist straight edge. I used a razor blade at a 90 and acetone to get the block as clean and residue free as I could. I have a motor I'm building that's sitting at Raif's shop, I'm waiting for him to get back from wcf. The block and head looked great actually. Honestly 100% of the time, I would of taken the head and block for machining. This is just a case of if it's fixed fine, if Not I'm pulling the motor for the winter. It's just 60 bucks. I have a brand new head I could of used, but I'm saving it for the new motor. I'm going to be finishing her up Monday. I can't see how a composite wouldn't seal, esp with studs. The new motor will be running a mls for sure.ill keep you posted

You guys are gunna think I'm nuts. I find it relaxing working on my car.... so it doesn't bother me. Only time in my life when time stands still and I'm not thinking about all the bullshit going on...

I feel the same way. It helps with stress. I get so focused that I even forget to eat sometimes!

 

[SasaniFab]

Ill know monday if im ok, the block surface looked perfect. The head looked good also. The car was never overheated and I couldnt find the area were the gases were leaking. Probably hard on a composite gasket.

I mean how much boost can a composite really handle? These motors are close to 25 years old, how long can one of these gaskets really go.

 

[biglady112]

Our setup was all new and freshly machined. We made it an entire week of racing at the salt flats on a composite head gasket over 800hp.

 

[92AWDHX40]

This is one of my stress releasers wrenching on my cars and others. Keep at it.

 

[Kapok6]

Boost isn't what you need to worry about on a composite. Think about cylinder pressures. I have ran a composite for years 30-40psi on a 55mm turbo. I have never had a gasket just arbitrarily fail, and I drive the car and push it pretty much every chance I get. I will continue to use composites. That's what's on my curt brown motor right now and it will most likely be what's on future motors. I am not a fan of mls for me and what I do.

holy shit, well there are many factors. Your not running factory compression yes? Its amazing how much power you pick up with a little more compression. I was running 34psi on the fp black with a fair amount of timing.....still think 5th gear got me. Never had one problem until 5th gear. Im gunna post my log so you guys can see exactly when it happened. If i was watching the check engine light I would of been ok. Id light to wire another light into that signal wire and mount it higher in my cabin

what makes a faster car....more boost lower compression, lil less boost and higher compression. Id imagine higher compression will get more response out of boost. Doesnt elevated cylinder pressure/ heat cause head gaskets to fail. I cant believe my standard arps cant handle a fp black at 34 psi

 

[gsxeclipse102]

I dont think the 34 psi popped your headgasket. The insanely high timing (26 degrees i believe it was) prob killed it. Did you ever find out if your base timing was off?

Oh yes, I dropped my peak timing to 16
Degrees climbing to 18 actually and fixed my base timing. I didn't have the crank pulley lined up as the pin was recessed and I wasn't paying attention. Honestly I never had a problem until 5th gear. It was the first time I shifted into 5th, it was for a
Short time to. I wasn't running lean, low air temp.... meth was working properly. I'm gunna post the log tonight to show you exactly when it happened. The compression didn't change as I tested it after. The only side effect was when I got in boost the temp climbed. I am also going back to the Mitsu alternator as I'm not getting the volts I like with the Saturn. I can't figure out why the hell its not charging correctly. With everything running the voltage drops to 12.6 volts.

Check this thread out. A lot of good info from people who have been doing this a while.

[gsxeclipse102]

Thats strange. My saturn alternator is always between 13.5 and 14. Did you hook up the s wire on the alternator? Its the sensing voltage wire.

The s wire is hooked up to a distriution block off the + on the battery, were i have my fuel pump etc. Its strange that the dsm link is reading low but when i check with the voltmeter at the battery i get 14.1

 

[biglady112]

That car only runs 8.5:1. I do everything I can to talk people out of high static compression. It has no place on a forced induction car.

You need to get it out of your head that 18* timing is okay. If your base timing is at 5* then you have 23* total going into the motor. If you have it at 10* base then that is 28* total timing. You have to add your base timing into the situation ever time. Most cars I play with end up in the 14-18* total timing area. Make your power with your turbocharger, not your ignition. High cylinder pressure is the devil.

As what has been said, high load and high timing as well as high load and low rpm will ruin your day every time. Your head studs are not the problem, your tune it.

Yah I got yah, this is a learning experience for me, I'm pretty confident without the meth injection the gasket/motor would have been gone awhile ago. If the motor is happy with the headgasket I'm going to lower my timing significantly and get on the dyno see what I can do. Still can't say enough about these motors, I don't care how primitive and inefficient they are. They just keep on giving.

Be thankful you have made it this far. Not a lot of folks have the same luck. A little research will go a long way. Knowledge and experience will get you to the next level.
