About 14,000 boosted miles now and nothing major except for the occasional gremlin. I figured it was time to see if I'd bent, blown, or busted a ring, rod, valve, etc., etc. We only did the compression test today because the place I was borrowing tools from said their air wasn't working right and would shoot condensation out - something I didn't care to have in my engine, so I opted out of the leak down test.

Background:
2004.5 G35 Coupe
14,000 Procharged miles / 32,000 total miles
6psi
Very conservative tune @ 350whp and 320wtq (hits 10.0 at past 6000rpm)
UTEC
Return fuel system with Walbro 255 and 720cc injectors


Results:
Top view (not sure how they are numbered)

|Front of car|
180*.......182
175.........180
172**.....178
|Rear of car|

*A small amount of oil was found on the spark plug.
**Tested twice, same results.

Plugs are one step colder NGK Iridiums.
They have been in the car for 2 years, about 10,000 miles.

I can post pictures up later, but honestly the plugs look fine. Even the one with oil on it doesn't look much different than the others- again, a very small amount of oil, but still there.

I really don't see the need to do a leak down right now. But, I'm just posting this as an FYI and to get other's feed back.

Thanks!

 

^ This is also what a friend just told me, lol. Thanks for posting. I had forgotten about VC's!

However, note that the oil was ON the plug IN the combustion chamber... still VC's?
