You need not crank it 8-9 times, A solid 5-6 turns will be enough to give you a proper reading.

Also you want to let your car warm up b4 you do the test and cold results will be lower then hot results. This is very important.

Be sure to hold pedal to floor while cranking it over till you stop.

 

Excellent write up with great pics!

 

Thanks for taking the time to make a DIY!

I have always wondered how to do a compression test, but I never knew how.

 

Stickied in the Correct place

 

Would it be ok to have had the car driven for about an hour before performing the test? I am about to purchase a S from a forum member and he will be driving down to my place for us to do the compression test. I am now worried that having the car driven for so long would affect the test. Any thoughts/opinions?

Should I just goto his place and do the test there?

 

awesome, thank you for teaching me something today

 

That's fine. As stated in the original post, you want the engine to be warm when performing the test.

 

Awesome!

 

^ can someone help me please?
