I posted here for the first time a couple of days ago (link) concerning engine problems. Long story short, I had a couple of friends help me out when I told them about it. They said it sounded like a fuel problem, so we ended up squirting some starter fluid into the intake. No luck there. We then took off the engine cover, as my friends wanted to take a look at the spark plugs. Lo and behold, the spark plugs in the forward bank were covered with engine oil. I talked to the previous owner, and he said that the plugs (and plenum gasket) were changed last year. Does a blown plenum gasket sound like the culprit? I checked the coolant, and it doesn't look like there's any oil in it.
