ya nvm didnt see he had posted it on here too

 

it was both #3 and #4 sleeves that went but #3 somehow got a piece of sleeve that put a crap load of nicks on top of the piston and on the combustion chamber and hit the valves.. got the valves replaced/seals and all that crap too.. lemme see if i can find a pic of the head after i blew up

 

dont u still have ur stock head bro?

 

here you go.. from the pic, it doesnt even look bad..

 

yes i do : )

 

throw that bitch on see if that solves the problem

 

If air is hissing out the intake, its indictaing that the intake valve isnt properly seated closed.

 

I agree with Rico. Try your other head.

 

an engines compression can show good and still have a bad oil ring but i still think the problem is with a bad head gasket or valve guide if you replace the head paint the hg with copper spray so it will seal any small informalities

 

yeah, thats what im afraid of.. i would be so screwed if i swapped heads, got everything back together and turns out to be a bad oil ring..

 

yes u would but atleast t is fixable just alot of work to fix it

 

X2, check the head.

 

What would ray have done to cause that? besides not decking it right?...

i mean...?

 

i would say that there is a valve not properly aligned

or HG however I have never personally seen a HG fualt do that to just one cyl

 

how can a valve be misaligned it isent adjustable and yes a hg will do that

 

I'm thinking the guide and seals aren't in proper shape

 

alright, update for everyone.. and i also need your guys input because at this point im at a deadend.. we switched out the head this past week.. its still burning massive oil so it has to be an issue with the block itself. its only on the 3rd cylinder and oil is still pooling on top of the piston.. i think im going to just throw in a stock shortblock and call it a day. i dont have anymore money to throw into this car.. anyone know where i can get a shortblock for a decent price?

 

A junk yard.

Talk to qwikredline. He probably has some lying around, as well.

 

wow man that really sucks.

but... if it's just that piston why not pop it out and rotate the rings, it's probably just the gaps lined up. I wouldn't think that would allow that much oil to get in there though, the situation seems a bit extreme.

 

The only way you're going to get air escaping into the intake mainfold is through the intake valve. I don't know what happened originally but I'll bet whatever it was, a piece of it found it's way into the combustion chamber, was too small to go through the piston but big enough to get between the valve and seat and bend the valve. It probably bent it bad enough to destroy the seal. At times of maximum manifold vacuum it would suck oil into the combustion chamber through the seal. There's at least PART or your oil loose. If you were driving around in limp mode the max vacuum condition was probably MOST of the time. And with it running on limp mode you might not have even noticed it was running hot which COULD have caused the head to warp causing an even greater oil leak into the combustion chamber. It's called a cascading effect. One tiny, repairable, problem causing ever increasing problems to the point of total destruction.

In ANY event you are a moron for running it AT ALL in limp mode unless you are SURE you know what is causing it and are SURE it won't cause catastrophic damage if it continues to run. BOTH situations that would only be apparent to a qualified engine diagnostician. CEL's are an INDICATION that something MIGHT be wrong with the engine or its control systems. Have it looked at at your earliest convenience. It probably won't destroy your engine. LIMP mode on the other hand is telling you STOP DRIVING. There is something wrong that might BLOW YOUR ENGINE UP and is meant to allow you to find a safe place to pull off the road and stop.

Chances are good to excellent you could have saved your engine if you had shut the engine down as soon as it went into limp mode. You would have had to have it repaired but not replaced.

 

it isent a valve seal and rotating the rings wont fix it if the gaps were lined up it show low cyl pressure i would pull the piston and check the ring lands or look for an oil control ring that has come out and slid up the side of the piston it can happen ive seen it before

 

if you had a failure...and there were shavings...did you happen to check the oil cooler and oil pump for shavings...that where they end up...

 

yeah good point, wonder if it's possible the rings were put in upside down

 

I've had an oil ring slide on me when I was doing my build. Luckily I had to take the piston back out anyway and that's how I caught it.
