    Bent valves a third time? Motor just broken?

    I've tried every firing order I could think of. The stock 2g is the correct one, and it does not misfire, but it also doesn't start. Cranks fine without plugs, with plugs it will try to start for about 5 seconds then stops cranking.A cold compression test showed cylinders 1-4 as 165 - 150 -...

    Bent valves a third time? Motor just broken?

    Engnbldr valves, the same kind everyone else uses.Nothing obviously wrong under the valve cover. Looks like some slightly bent valves again.Not much can be learned until I at least get the timing covers off and I can check my timing marks on the plate. Will report back results then.

    Bent valves a third time? Motor just broken?

    Everything I have done to this car was after long research, not much "guessing" involved, but I think you did just hit on the guess I made wrong. Here's my theory:The first build I timed everything right. It ran fine, but I forgot the woodruf key, so timing probably jumped a lot when the crank...

    Bent valves a third time? Motor just broken?

    Head was resurfaced twice and my machinist knows these cars. Putting it back together so many times may be the problem, I know how to put it back together but maybe I am messing up somewhere.The timing mark on the plate wore off. It is a trimmed-up 2g one on a 6 bolt.Bottom end turned nicely...

    Bent valves a third time? Motor just broken?

    Lifters are brand new topline ones this time and I bled them and made sure they compressed easily by hand.The bottom end turns freely by hand, everything turns easily until you put plugs in. There are places it is harder to turn than others, and the engine seems to want to turn backwards at...

    Bent valves a third time? Motor just broken?

    I keep rebuilding this head and it just keeps bending the valves on start up. I think I am doing everything right, tensioning the belt with the Jay's racing tool. Timing looks good but all I get is backfire and no-start.I had some serious head carnage that put the car down a year ago, all the...

    Comp Cams 101200 users, have a few questions....

    You will need better valve springs, stockers are a bad bet as I learned firsthand.I kept the stock valvetrain going from fp2s to 3s and it split a rocker arm in two when the spring bound, bending all 16 valves .It's worth it to put $1k into the head first, rather than after you f up your...

    Questions for Justin...

    Lithium based grease. It turns easily by hand, but does not continue turning after being let go at all. I think I will try mounting it up and priming it to see how it turns then.

    Questions for Justin...

    How stiffly should a turbo turn with just assembly lube in it?It must either be that I don't know what to expect from a rebuild or the ebay housing is not machined right?
  10. deflator

    Questions for Justin...

    Ok. I did that and it fit, then I greased the o-ring up much better and made it fit, but now the turbo won't turn freely when I put the snap ring on. Oil sealing ring probably got deranged?It spins freely, considering the heavy assembly lube I used in it, until I put on the snap ring. It spins...

    Questions for Justin...

    Justin, I am trying to build a billet 20g but the compressor housing just won't go on far enough to get the snap ring to really secure or to align the dowel pin.I think it is a K1 wheel if it matters. Comp housing is an ebay stock-appearing unit for making a 20g.I am sure the internals are...

    ?? Is a special socket needed for removal of ARP head bolts

    Kinda OT, but on the subject of ARP headstuds, if you get dual valve springs the nuts will no longer clear. ARP sells a nut with a smaller collar, on my 7 bolt head I needed 4. The two middle, top right, and bottom left. I never see this information on here and it seems like a problem people...

    2G Starter broke crank bolt loose?

    Can do, but I just tested the exhaust side and 4 leaked, 2 badly. Roughly the same as the intake side did.It's the engnbldr valves right? They are only 120 plus shipping so a new set is not a big deal.

    2G Starter broke crank bolt loose?

    Ok, after filling the runners with pb, then tapping each valve tip a few times 6 out of 8 intake valves leaked. 2 were streaming. 2 were slower leaks but immediately apparent. The other 4 leaked a very small amount, and it took a 5 count for any pb to appear.So, new set of valves. Guides...

    2G Starter broke crank bolt loose?

    To check for false readings? Everything is new and clean. Never started just cranked.I don't have any brass drifts, but I will test again, filling the runners this time. I can order drifts if this is an essential part of the test.

    2G Starter broke crank bolt loose?

    I flipped the head upside-down and filled the CCs with alcohol.2 started streaming almost immediately out the exhaust. I left it for an hour and one was empty, two were half empty, and one was full. The full one still had a trickle come out an exh. valve, but it took an hour. Only the ones...

    2G Starter broke crank bolt loose?

    Ah, so beefier springs were why it felt different to turn the engine by hand.Seems this is the source of everything. Explains why timing jumped so badly the first time too. It was the first work I did when I got the motor many years ago and I screwed up it seems.The head is already off, but...

    2G Starter broke crank bolt loose?

    The woodruf key isn't there! It must have not been installed...LOLThe crank was down to ~40 ft/lbs of torque. Must have been enough to hold for a minute, then let everything slip because there was no key.It still doesn't explain why the engine didn't turn uniformly, or the nasty clunk...

    2G Starter broke crank bolt loose?

    I even made a tool to immobilize the crank for torquing the bolt. This was put together a few years back though, so I can't be certain I put the correct amount of torque on it.It happened twice in a row too. I didn't note that the bolt was loose the first time, just that the crank timing was...

    2G Starter broke crank bolt loose?

    I went to start it after a head rebuild due to 16 bent valves. Timing marks were perfect. The head is built, with supertech duals and FP3 cams.No start. Got a loud clunk that sounded like it came from the head. I thought it was the drained lifters being loud, and it turned freely, so I kept...

    Kiggly spacer & the axle stay

    I can't figure out why my trans keeps leaking at the rear axle seal.I replaced it, and didn't touch it, but now it leaks again after 20 miles.I think the problem is a kiggly spacer moved my axle out far enough to cause sealing issues. Once bolted to the block, the axle is about an inch...

    Sheared off auto-tensioner plunger, why?

    Yeah, I learned that info after compressing it quickly.But how did blown seals lead to the top of it shearing off? That is what I don't understand, since it snapped at the eyehole for the pin, near the top of the plunger. At least it left no doubt that something was wrong.

    I was hoping not to have to replace my timing belt auto-tensioner on my engine, a 6 bolt with a 2g head. It had 70 miles on it.But...I tried to set the preload on the pulley with the jayracing tool, and the pin would only come out when there was no load on it. When preloaded, it would not...

    Re-ringing after 70 miles?

    That's why I don't know how to judge the results of the oil-leak test, since I don't know how broken in it is yet. It happened with only 70 miles on the rebuilt motor. I was hard on it from the first mile though, using the motoman method of break-in.

    Re-ringing after 70 miles?

    I had a rocker arm crack in two, and all the valves smashed the pistons badly. I fixed the gouges up best I could on the pistons, then tested for pinched rings using this method: http://www.dsmtuners.com/forums/newbie-forum/450572-how-check-pinched-bad-rings.htmlThe oil drop was minimal...

    TBelt slipped 6 teeth, 6bolt w/2g head problems

    Yeah, and the valves are pushed into the sides of the head too. It's trash. But are the pistons going to be acceptable with that kind of gouging? I'm going to clean the high spots up with a dremel and test the rings after cleaning all the metal out.How much can a camshaft lobe be scored? One...

    TBelt slipped 6 teeth, 6bolt w/2g head problems

    I found interesting damage after taking off the tbelt, the exhaust cam gear has a chunk missing. I may have not done the belt so wrong after all, and it was an internal failure. They were plain FP3s.

    I can't get the timing-belt tension right on my 6-bolt swapped 95 with a 2g head.The lower timing tin must be wrong since the access hole for the special tool will not let it go in, the angle is wrong. This led to me trying to time it without using the special timing tool and it slipped 6...

    mod choice critique, hoping to go e85

    Injectors can be resold, and they are not hard to change out. 1050's would be fine with that turbo and 25-28psi but you would have to go above 80% duty cycle. 1200s might be a better compromise.I would get an evo3/RVR intake manifold instead of an SMIM as well. They can be resold for the same...

    EF1 vs 68hta vs S256 vs HX35 so many choices

    The EF1 and holset compare in price only. The EF1 is a bit cheaper and a lot easier though, and not that much slower. Especially on the street. And a billet 20g is somewhat cheaper than the EF1, alot cheaper if I don't rebuild and just slap the wheel in.

    So, $2-300 for the hx35, $300 for the housing, $150 to rebuild = $650-750Extremepsi sells the plain jane s256 for $850. I can't find where to get a bolt on housing, but it's probably $300 for a total of $1150. As much as $500 more than the holset!So the borg is hard to justify on this...

    EF1 vs 68hta vs S256 vs HX35 so many choices

    Good to know Glenn. But fitment was only one of my concerns about a hx35.The things that turn me off about holsets are that I would need to make a 12an+ drain, that it is designed to run more boost than I want to and is not fully "awake" under 25psi, and that I am buying an old turbo which I...

    EF1 vs 68hta vs S256 vs HX35 so many choices

    I want a 55lb/min turbo eventually, but I don't want to use an old turbo if I don't have to. It sounds like the hx35 and the borg are going to be tight fits, but possible. But the borg is a new turbo, and it's in the $1k budget after selling the 16g and getting a BEP housing.
  39. deflator

    EF1 vs 68hta vs S256 vs HX35 so many choices

    Yeah, that's what I want. Maybe I should just stick it with the 16g and get bigger injectors and pump. What I really want to know about is fitment. Does it require a new oil drain too?

    EF1 vs 68hta vs S256 vs HX35 so many choices

    That's good to know that it fits glenn, and I probably will get a hx35 eventually. But I want to learn to weld in the near future so I can do that one myself some day. Otherwise, a twin-scroll 12cm t3 hx35 breaks the bank.Looks like I will just upgrade to billet 20g for now and leave...

    EF1 vs 68hta vs S256 vs HX35 so many choices

    I thought that the 16g would need machining to become a 20g? How much does machining run, $100?So I could get the fp 8cm housing right now for $200, and this wheel and housing for $200, and have an almost new billet 20g that bolts up the same as before? If I rebuilt it too it would be about...

    I haven't, but I have read that. And that's why I've been looking to stay TD05 with an EF1 or a 68hta. I don't know which is a better deal, but I think the 68 is the better turbo and it is new.
