compression test numbers a little low
if you look in my sig i am selling a teg for 2k.
this was the test car.
i'm well aware of how to determine if it's the valves or rings.
the b18b gave a 160,160,160,50
by those #'s it is safe to say that 1 of the cylenders are fried. i dumped oil in the
cyl with the 50 reading and the cmpression # did not change which leads me to belive it's the valves. so my question is........
would'nt the car run like complete crap if there was 1 cyl registering a 50?
thanks

Re: compression test numbers a little low (b16hf)
i have a CEL on for cyl mis-fire.
the car starts up and idles fine. smells a little rich but does't blow smoke in anyway.
i would think with 1 cylander having such a low compression # the car would idle like crap and not run well at all.
i'm just puzzled because the even with the low reading the engine sounds and runs great.
would a valve job correct this?

do a leakdown test....it will give you better information to work with, and you can pinpoint exactly where you are losing cylnider pressure.

Re: compression test numbers a little low (Djaric)
well i dumped about a capfull of oil into the bad cylinder and the compression # stayed the same so i would assume that the rings aren't the problem.
