I checked my plugs to see how well my a/f curve was and they were as expected, a little dark from running a tad rich. No big deal.... EXCEPT FOR ALL THE OIL on plugs 2 and 4.
I went ahead and did a compression test (5 second turn with WOT).

Here are my numbers
#1 230
#2 230
#3 200
#4 210

The numbers seem a little funky but tell me there is nothing majorly wrong with #2 #4.
I am worried about the slightly low numbers of #3 and #4, I am guessing that is normal for an 80k motor.
Why do you think all that oil ended up on my plugs?

Could be valve seals...

Aeka GSR

ouch, ive never heard of valve seals blowing out under boost... guess there is a first for everything... anyone else have there thoughts?

You compression numbers look fine. Is the oil on the electrodes or on the threads? If it's just on the threads it could be a torn valve cover gromet around the spark plugs. I've seen that a couple times on older motors. Replaced the gomet seals and no more oil.

Aeka GSR

yeah its only on the threads.. i think.. ill check it out in the morning

Your comp #'s are fine, I belive up to 28psi difference or 20% is acceptable.... so your good, my 2nd and 3rd cylindars have always been a smidge lower then the 1st and 4th.

My 1st cylindar is awesome
