oil with spark plugs don't mix

nu_supra04 · 09-25-2009, 07:56 AM

so i just recently bought a 1990 supra turbo with about 120500 miles on it, i plan to keep the body pretty much untouched unless for paint but I'm planning on definitely adding a a lot of power to. so i right now i got two questions, i recently read that getting a divorced downpipe adds hp so can anybody explain who that works??
also i was recently changing the spark plugs and as i took the old ones out some were covered in oil, any ideas to what is causing that?
any help appreciated thanks
