Didn't bleed lifters - 90 cold compression new engine

[trunks11]

Yeah, I tried that too and no change. Dave on ecm said it looks fine.

[trunks11]

Looks like I've got a bum motor. Blow by is shooting oil into the exhaust making it smoke like crazy. After talking to Julian sounds like the guy put acl bearings in and didn't clearance them. I think that would explain why it ran good for all of 3 minutes.

MAP didn't bother to call me back and local shop wants a fortune so looks like I'll be pulling the motor again.:woohoo1:

I would have it looked over more then once by more then one person before you just yank the motor.

[trunks11]

I'm going to bring it home and run it for a while longer to make sure. They did say after running a while it wasn't smoking as bad until you give it some throttle. It's also leaking a lot of oil from what seems to be the rear main. I read somewhere that blow by will do that though.

He told me 25 hours to do the ring job which seems ludacris to me.

I thought this motor had 7 miles on it? how does it have excessive blow by and need a rebuild? Does it turn over really hard or something to signal bad bearing issue? or are you just trying to point at an issue that you can blame someone else for? I think its an electrical issue, either fuel delivery or spark not on time, or not the right amount of fuel.

[trunks11]

I"m not trying to blame anyone, just find the problem, fix it, and get the car to run. The 02 housing is caked in oil, and leak down test pointed at the rings not seating.

I was hoping it was electrical, that's why I took it in. Every component of the system has been replaced or tested with a known working unit. I've tried two sets of injectors, new plugs, swapped out cas, coil pack, power transistor, injector power pack (silver box on firewall), the ecu was checked when link was installed. I have an afpr base fuel is at 38psi. There is no cel at any time.

[CarPsyco84]

you said it had 140psi of compression though right? It could be a valve seal issue also... what was the leak down %?

[trunks11]

I will ask them % leak down when I pick up the car tonight. They told me it was leaking past the rings.

I had those high compression readings cold with a cap full of oil, but they told me around 100 +/- 5 psi when they did it warm. I've got a cheap testor and I assume they can at least do that correctly and I was wrong.

Would a valve seal allow all that oil into the camber? Am I back to my original problem with the lifters and I have bent valves? I guess I'm going to try to run it a while and see if it improves. If not, pull the head and see what's really up. Also, when I've tried boost leak tests, the car doesn't hold pressure and it sounded like it was going right out the exhaust no matter how I had the tb turned - not sure if that's relevant.

[trunks11]

Shop didn't have there leak down test numbers but said it was way over 30. I ran it today for about 15 minutes reving it around 4000 rpms and checked compression again. 100 100 90 120. It stopped smoking so much after running a while, but I had to crank for ever, pump the peddle, and keep jumper cables on it. Car actually idles now when warm.

I would take out and run it hard for a little bit to try to get the rings to seat, but its leaking oil like crazy. I'm hoping a crack in the oil pan since I just did the rear main. I'm not sure if it's worth fixing it - if indeed the engine really had 7 miles on it they should be seated by now?? When I was reving it actually got hot - fan wasn't turning on, but I figured that might help them seat too.

[CarPsyco84]

If the valves are leaking, the exhaust ones leak into the exhaust port, and intake ones leak into the intake port which then goes through the combustion chamber... Leaky rings tend to smoke more under power and then go away at an idle... valve stuff tends to smoke consistantly.
