2001 Rx300 Engine Compression

[Tgready]

I have 2001 Rx300 with 205K on it. What should the engine compression be on each cylinder when I do a compression test?

Well. Try to find the service manual (as distinct from the owner's manual) for your car, it should have such data

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.
