Only Buicks Posted November 28, 2006 Share Posted November 28, 2006 I am just getting ready to drop the engine into my car. I want to check the compression before I install it to see if all is well (somewhat). What should I get for a reading on a cold engine? Are there any other checks I should make prior to installing it into the car? I beleive this engine was done some time ago and then just never installed in the car. I removed the head and the cylinders look good, no ridge. The valves look like they where probably re-ground. As the previuos owner passed away a few years ago I can't call him up and ask him how far he got and if there was anything else he needed to do to it. I have never rebuild an engine so I am not really sure what I should be watching out for.Any help or suggestions would be appreciated. Link to comment Share on other sites More sharing options...
Mark Shaw Posted November 29, 2006 Share Posted November 29, 2006 Without a reference manual for your car, you can still verify that compression is very close to the same on all cylinders. However, I suggest you add a teaspoon of Marvel oil to each cylinder and crank the engine a few times before testing compression on a cold engine.
