Ok I've got a 91 s13 with a sohc motor in it. I ran a compression test and found out that cylinder 4 is running at 60 psi. The car has an exhaust leak out of the manifold but surprisingly doesn't run all that bad considering. Is there a way to test whether its something other than the exhaust leak causing the low compression? If anyone has any ideas im open to suggestions. thanks
