hey fellow g2ic owners i just did a comprehension test on my 90 ls. well when i took my plugs out i found they were soaked in oil.my test came back 200 on all four cylinders.well i have blue smoke coming out my exhaust.bottom line is
:think::think:does that mean i have bad rings and if not what is it
Not sure if this will help but when you take off the valve cover there are 4 rubber seals that go around each spark plug an prevents oil from get in. The hole were the spark plug are just replace those rubber seals an you should be fine with no more oil in the plugs
no man its on the bottom not the top were the plugs are and my valve gasket and tube gaskets are new
so there was absolutely no oil on the top of the plugs/in the socket when you pulled them out?
no
not sounding to good the reason for the high numbers could be because the oil was creating a temporary seal when you performed the compression test. Did you perform the test when it was warm or cold. It sounds like your rings are going but if you want to know for sure you could also do a Leak Down test to pinpoint the problem if you performed it cold there a possibility you could have extremely leaky valve stem seals but if you did it warm its most likely your rings are failing. Keep us posted man.
well see i did it cold and got 200 200 180 190 then 200 200 200 200 i let it warm up and got 200 200 200 200 :hump:
Sounds like it could maybe a leaking valve seal but with out doing a leak down test thats just my best guess
OK well i have narrowed it down to valve seals or piston rings does anyone know how to find out witch one it would be:bang:
This^
+1 on the leak down its a little more complicated than a compression test but still easy to do here is and idea off what you will be doing i know its on a different car but the test is the same http://www.superhonda.com/forum/f49/howto-perform-leakdown-test-257985/ also remember to hold the ratchet on the crank pulley bolt when putting air into the cylinder the air pressure has enough force to push the piston out of TDC. G2ic also has good articles on doing a leakdown test just remeber to search.
Thanks for the Leak down link. been wanting to know how to do this.
