Someone please HELP ME i have oil inside my exhaust port not alot but enough, the guy who did my head said its the VALVE GUIDE'S on intake and exhaust there worn out. its a ls-v 81. bore 12.5/1 ported gsr should make 215 or so i hope but the oil leak is killing me. I put 100 mile's on it noticed that oil was comein out the exhaust so i took the head off and changed all the seal's and then put my head back on put maybe 15 mile's on it and again i noticed oil in the exhaust port but non in the intake, i really dont think it's the ring's should i just get all the guide's done or could it be something else?........ some one please help me

You should try doing a compression test and see where your numbers are. When you took the head off did you get it pressure checked for leaks? If not next time do so. If your rings are shot you should be smoking out the tail pipe. The reason you not having it on the intake side because it pulls in air to the motor and exhaust is where everything is forced out of the motor.

 

MY LS/V IS 81. BORE WITH A 81.5 BORE HEAD GASKET IS THAT OK?.......

 

kinda of on a side note...if he does a compression check, and all the numbers are good. what could it be then?

 

valve seal
had the same thing happen to my ls vtec
hope it helps

 

CHANGED ALL THAT THO

 

SEEMS TO JUST BE BAD LIKE THAT IN THE #2 THE # 3 HAS A LIL TO BUT THATS IT

 

the only other thing i could think of would be blow by

what would cause this, and can be fixed by? sorry to thread jack, but i have similar issues.

 

YEA I CHANGED THE VALVE SEAL'S NOT VALVE GUIDES THO THIS MOTOR HAS LESS THAN 200 MILE'S I PUT 130 THE HEAD CAME OFF CHANGED THE SEAL'S AND PUT MAYBE 15 MILE'S AND OIL IS STARTED TO LEAK AGAIN. ALSO WHAT WOULD MAKE A CAR BOG AT HIGH RPM (NOT TUNED,GSR PUMP, GSR INJECTORS, AT 60 SOMETHING ON THE REGULATOR) STARTES TO BOG RIGHT AFTER VTEC KICKES SO LIKE 6 AND BOG'S UNTIL I SHIFT.

First , lay off the caps. If you changed the seals and your guides are worn, changing the seals does nothing.

duh.

 

Yet another example of screaming denial.Get the guides fixed and get it tuned.And I will say again.Compression and leak-down tests will not show bad valve seals.In both these tests the valves are closed and the seals are isolated from the test.

if the piston rings are not staggered correctly then oil will "blow by" them up to the combustion chamber

I have heard this said many times,but it doesn't make any seance.In a healthy engine the rings rotate around the piston in the grooves.If this doesn't happen then the rings wear thin on the thrust side (like a two stroke does with pinned rings).I am sure there are many times that the ring grooves line up.And besides pressure isn't "line of site".After building engine for twenty years I just don't believe it.

 

well im kinda glad im goin to take the head off cuz when i put my motor together i put a 60." head gasket just to get it together so this time im gettin a smaller one want my compression back

What are you talking about?

 

i didnt no it was on my bro's account anyways i have a super thick .60" headgasket and i was sayin when i go back to a .30" im gettin some of my compression back. my head shop told me when i take it in this time i should do a valve job how many degress should i go and whats a good valve probably flat since this will end up on the bottle

 

Ok. Makes sense now.
