My compression check...

[CajunKenny]

Here are my compression numbers @ approximately 7k miles.

#1 - 124
#2 - 129
#3 - 129
#4 - 125
#5 - 126
#6 - 125

Leak down tests were good.

Kinda low, you have access to another tester?

At least they're even... lol.

 

[CajunKenny]

Well, I did this just by pulling the plugs and the engine was cold. I didn't follow the TSRM.

I know...I know... :slap:

I'll do it again here in a week or two with it warmed up.

I was mainly looking for even-ness in compression. Its the first check since my 5200 rpm BHG.

Mine were 130-134, and I thought mine seemed low as well. But my engine burns very little oil and runs extremely well even at 21 psi. The previous owner added a metal head gasket that may have changed the compression slightly.

I think evenness between the numbers is most important.

I think evenness between the numbers is most important.

^^^ I second that. Even over "high numbers".



Also, you DO need to do the check warm, or all bets are off.

What were the leak down %s? Thatll tell the engine health more then compression tests.
