plugs keep fouling..help!!!
plugs keep fouling..help!!! ive been trying to figure out what is causing what looks like oil to get onto my spark plugs, enough to cover a few of the plugs and cause a misfire. i did a compression test, you can see it in the pic below. i have all new valve seals
its a 08 l76 with 317 heads.
btr springs retainers and valve seals
tick turbo cam
br7ef plugs at stock gap .24
speed density tune, no maf, no o2's
i have breathers on the 2 rear valve cover ports. and the valley cover port running into the tb.
compression test was held for 2-3 seconds per cylinder
took pics of all the exhaust ports. all look similar except for #7
i can take any pics you need to further help. i appreciate all feedback
thanks!

Stray oil... Hope you are using high tension oil control rings for boost and napier second scraper down those are your oil control rings, when they don't perform well enough in a uniform fashion such as, must often selection was flow.
Often misunderstood and poorly design engine evac system can red flag in similar fashion.
A hotter plug will help
Also who is tuning your engine a revision by a qualify second opinion may proof helpful, not an invitation to start a war among tuners but rather to eliminate possible human error before it gets to a more expensive path.
Ignition system spark intensity test.
Check all your grounds clean all contacts and make sure all wires are in top shape, make sure you have enough grounds, locate/check ECM ground wire.

the bottom end is all stock minus the cam. so whatever rings they came with is what is in there. my tuner is a good friend of mine. im sure he would not take any offense having someone double check it. i know it runs really rich when it first starts up till it gets to temp. its just odd, it happens often (every 500-1k miles) but randomly. yesterday i was out with the car all day, no issues. get home, park it. wake up start the car and the plugs are fucked. its very frustrating b/c the way my headers are i have to pull them off to change the plugs on the pass side
