Tgready Posted September 16, 2015 Share Posted September 16, 2015 I have 2001 Rx300 with 205K on it. What should the engine compression be on each cylinder when I do a compression test? Quote Link to comment Share on other sites More sharing options...
eugene.s Posted September 22, 2015 Share Posted September 22, 2015 Well. Try to find the service manual (as distinct from the owner's manual) for your car, it should have such data Quote Link to comment Share on other sites More sharing options...
franknickells Posted April 8, 2016 Share Posted April 8, 2016 ideally compression is like blood pressure. Must be uniform across all cylinders. Dry compression around 150 psi all across is fine when the engine is cold. Quote Link to comment Share on other sites More sharing options...
