These are the pictures as the head sits.

in order from 4-1.





These are the compression test results from about a 2 weeks ago.





I did an oil change about a week and a half ago.I checked the oil, and It was in between the bottom dot, and the bottom of the dip stick.

Rings? Oil and smoke was comming from the breather box when I disconected the hose that goes to the PVC valve.

I have an entire gasket kit with acl bearings, and NPR Piston rings. Maybe the valve didnt seat right when I put my KMS Dual valve springs in right? Im taking it to a shop tomorrow to get it pressure tested, and have the guy's reseat the valves, and mill the head if it needs it.

I could use some help with this one..

 

46 views and nothing?

 

Well I think it would be safe to say you have some ring or valve seal issues.

 

valvesteam seals.. probably the rings from the crankcase pressure too but i'd get the head redone and then do it again..130 and 230 are a big difference.

 

I wouldn't worry about a little smoke coming out of the breather, but those compression results are all over the place. On the low cylinders, try dumping roughly a teaspoon of oil into the open spark plug holes, then redo the compression test, if your numbers go up significantly its most likely a ring issue, if the numbers don't move or only move a little its probably a head or valve sealing issue. Also, make sure when you do the compression test to open the throttle 100%--its easy to get low numbers by forgetting to open the throttle on a cylinder.

 

I'd do a leakdown test, but I think you already have it apart. If you do, you kind of hosed yourself in terms of isolating the problem. Stem seals aren't going to cause THAT much build up in the chamber. You could also check the back of the valves around the neck inside the ports. If it was leaking extremely bad from the seals you should see build up. If all you did was replace the springs/retainers, I can't see how you would have messed up the stem seals. With the oil consumption the way you describe, my money would be on the lower end (rings/headgasket). Its possible the headgasket took a crap on you since the two low cylinders are right next to each other.

 

The throttle was open all the way, In the first compression pic, you can see the screwdriver holding it open. car was warmed up. I didnt put oil in the combustion chamber though. to test the rings.


I did the Leak down test when I found out the compression put 90 psi in each cylinder

2nd and 3rd cylinders werent hoilding over 30 psi.

The head is at a machine shop right now. Hopefully the pressure test well tell me the valves needed to be reseated.

 

Posting pics in a few minutes...

 

How's the valve adjustment?

 

lol what piston rings?

Damn, that same thing happened to me last dec.

 

Why would it do that? I cant decide if I want to go all motor, or turbo now....

 

i was going to say cracked ringlands even bore i saw the pics.. detonation killed your pistons and bearings

 

was the motor stock or modified and untuned

 

Next time don't spread liquid gasket all over the damn oil pan gasket. Only need it in the 4 corners on the pan side. Thats IT. It will seal just fine when properly torqued.

That engine wasn't tuned correctly and thus is dead.
