I really don't know at the time. As of right now I am ungodly pissed and contacted the seller of the car.

If you end up keeping it. A loose FPR is bad and probably causing a problem. I'd be hopping right to fixing that and the oil pan. Thinking more.. you moved the fuel rail and maybe in the process the FPR was loose and now is very loose and causing problems.

Hmmm, I did do a vacuum test with a pump on the FPR, and it is holding the vacuum properly, so it may not be that. I think it was the weak spark plugs and old wires and was dumping excessive fuel in and getting into the oil from leakdown past the rings. Possible, no? The car has always idled like **** and would stall since I got it, but remember, the spark plugs and wires are as old as the engine is. The engine only has 65-70k, and my dad told me that the noise I may be hearing is the lifters because they do not have proper lubrication. Please also take note that I have only had it started 2 or 3 times after I noticed the excess gas in the oil, so bottom end damage doesn't seem too possible right now.

EDIT, last night, I found a broken spark plug (the side electrode has about 1/8" missing), and I think it has been gone for a LONG time.

Sounds like excessive KR took one or all of your plugs out. Got a scantool?

I'm gonna have to end up buying one from Series one performance. Either excessive KR, or the plugs were just absolutely ancient. It makes me mad that the swap was done into the car, and spark plugs and wires weren't even taken into consideration.

Here is the plug, bad pic, but it gets the idea through.

yea.... that might be part of the problem....

There are cheaper scantools than Seriesoneperformance. And I don't know if he'* even in business any more.

Go to eBay for your scantool.

That plug died from detonation. Old will erode the gap to well over .1" before it'* gone. Knock/detonation blows it away like that.

The FPR vacuum connection my hold vaccum. But.. is it inserted into the rail and secure? You made it sound "loose" if so..the vacuum test isn't admissable evidence.

Oh no, the vacuum line was loose. The FPR is secure and very tight.
