Thread: compression test on my old 350...

Tweet

Hi Folks, I just did a compression test on my old 350. Borrowed the gauge from a car shop, so it's readings are very possibly correct. This is what I got, I did the test twice (three times on the weak cylinders) and always got the same result, so it probably won't be a measuring error. The passenger side head gasket is blown, when I crank it over water sprays out of the spark plug hole
The engine doesn't run all too well and as I mentioned before, it doesn't respond too well to timing adjustments (wouldn't with 3 cylinders dead)
What do you think it is? Doesn't look like the piston rings to me, I would guess it's just the gaskets...
