Here's a little background of my motor Just had 383 built last summer,It was given a computer reprogram by Brian at PCM for less.Heres my problem I didn't get to finish exhaust due too y pipe not made right for my headers.I just have open headers I started it around 10 to 12 times for about 10-15 min and drove 3 miles car ran sounded great for the first couple minutes then was undriveable.I know this was probably due to the open headers causeing the computer to think I was running lean.Anyway The car would't even start anymore checked plugs gas soaked they were dripping fuel.I changed the oil and there was gas in it how bad is this?I am going to get the exhaust done soon.I have a compression tester how do I go about and do a leak down test?Thanx in advance

 

Sounds like you've got fuel, did you check for fire?

I had the same issues when my opti crapped out right after I did the cam swap.

 

Fuel in the oil is usually an indication that your motor is running rich which results in cylinder wash.

 

BINGO....get the leak down done

 

I know I have spark,How do I do the leak down test do I pull all the plugs are just one at a time?Thank you for the responses everyone.
