Hi, I'm going to try and rent a compression tester tomorrow and do a compression test and a cylinder leak down test. Will I need more than just a compression tester to do a leak down check and is it ok to perform both of these tests with the exhaust manifold removed and having the exhaust ports exposed. Also, right now I have neither engine oil or coolant in the radiator as I have removed the ex man and turbo. Any thoughts on this? Will a factory service manual provide the info needed to do these tests? The car is a mitsubishi eclipse 2.0L turbo and as I mentioned in the past you volvo guys have been very helpful which I really appreciate. Thanks in advance, Greg
