I had a compression test done on my 94 850T 96,000 mil.
Lo end 130psi, high 155 psi. Is it OK ? I have high crakcase pressure.
Thanks,

you should be still ok at those readings. As to high pressure.. check your flametrap (non turbo engine) The high pressure probably caused the lower compression in the cylinders to begin with. Also a sign is leaking around the oil cap and dipstick coming out.

Before I bought my 850, I had a compression test done at one "neighborhood shop" which showed widely varying results for each cylinder. I then took it to a dealership (that wasn't involved in the sale) for a second opinion. Their test showed much better results. When I took it back to the neighborhood shop for a re-test, the results were better, as well.

So if you have any reason to doubt the accuracy of the compression test (like if they didn't use the most updated equipment to do the test), you may want to get a second test done somewhere else.

I think you are at the end of the spectrum in tolerance. It is supposed to be that all cylinders are within 20% of each other. Otherwise you might start seeing performance issues like rough idle/missing and running rich.
