Hi all

Can anyone tell me what an acceptable set of tests would read like on a 1989 3.2? I've asked for a set to be done on a car and wanted an idea on what the parameters should be. The car has done about 95,000 miles.

Cheers

Any leak of more than 10% is not acceptable, even 10% on a cylinder would suggest the engine has some wear and is more than I would expect on your paticular engine. Of course, some testers may show higher/lower results than the kit I use.
