Head won't effect it this time, (sealed tight checked it with acetone) no bent valves likely with those numbers, try the oil on the rings now and see if you don't get a different result. Are you using the same tester you did and identicle procedure, revolutions etc? Was it tested at operating temps both times?

We will have to redo it again. The same tester is used and the car was cold this time. It was warm last time we checked and it had good compression. We have no way to get it warm now. I am pretty sure the same revolutions. We did 7. I hate this stupid car.

Get it running and then test it again. Did you try a different set of coils & transistor? You should see about getting eric to come check everything for you, he catches that stuff pretty quick.

If you want, I can probably make it out there Fri night, Sat afternoon or Sun afternoon.Which ever works for you.

I am going with either a bad ground (would explain slow cranking) or a bad ECU.

I believe they've tried several ECUs.Ground is a definite possibly, it wouldn't explain the lack of spark though.

We tryed 3 working ecus and that isn't the problem. We tryed a two coils but still no luck and we tryed another power transistor. All of them were off working cars. To get the starter to crank, we had to rewire the starter from the ignition skipping the relay to the signal wire because the signal wire didn't get power. The starter was grounded though so I don't think that effects it though. Erik, I will PM you and leet you know what time works best. I will have to look at my schedule first though.

I think Jet was talking about the chassis/engine to battery ground.

I thought so too, but I am not sure what we would have disconnected. I don't see any missing. I might try to add a few more today.

The ground wire is connected to the battery. The starter seems fine to me, it is just noticeable that there is a lack of compression. Similar to the bent valves sound, just not as severe. The ground is connected to the starter as why the car still cranks. It is grounded on the bolt that mounts the starter to the tranny.

What is pissing me off it that I did 5 head swaps last year and I had no problem what so ever. This time, the valves get bent in a rebuilt head, and compression drops from near perfect to the rebuild range on the other after the other rebuilt head. I gained 5 psi per cylinder in my car after a new HG and valve seals.

You should ask James what I told him the night he picked up that head when he called.

john 02-24-2005 07:25 PM

Re: problem
 
Yeah, I remember him saying the valves were pitted. I thought it would still seal though. Didn't ever think it would be this bad. Makes up for the little power gained by the 1G mani, TB, and 1G head. Should have just replaced the bad sensor and not tried to go overboard by doing valve seals, HG, and timing belt...

So does this thing run now?

john 03-05-2005 02:16 AM

Re: problem
 
Nope...

john 03-05-2005 02:18 AM

Re: problem
 
...has compression atleast. Turned over once and died right away is the best it has seen.

Re: problem
 
DAMN. How many fucking problems can you have at the same time? I think Mike and I will head out there again tomorrow, make sure the battery is fully charged.

Re: problem
 
Thanks alot for coming over. The car now runs and can get on the dyno for a decent tune.

You sure you guys dont want to get rid of that car so in the future it wont break ;)

john 03-06-2005 02:09 AM

Re: problem
 
No, it is just that several things went wrong at the same time. Had "phantom valve bend" on the ported head, a head with crappy compression, the 2g head finally back on. Then no spark twice and spark and fuel without starting. Everything was going wrong and I did not have any time or will to help him with the car after swapping the head, intake mani, etc for the third time. After swapping it three times, the car ended up with the head that was on it originally instead of an upgraded 1g.
