Re: Adverage Compression V6 Alfa?

I assume you're talking about compression testing the cylinder? My totally uneducated guess would be 120-150psi, but mainly worrying about large differences (more than 10%) between cylinders rather than absolute values?

Re: Adverage Compression V6 Alfa?

Cool! Thanks for a quick reply and yes i am talking about a copression test! I have just testing my engine this morning and they are all in the region of about 110psi - 125psi Im a mechanic by trade anyway and I know that what you said is the normal range anyway! But wasnt to sure what a Alfa should be as I know that a Ford Mustange V8 for example is only 100 - 110psi! Anyway thanks again for the reply
