Well check the valve covers first..grab a clean rag and wipe all the way around the edges. If not wet...ur good. Anothrr clean rag amd reach back to the back sidr of the intake... (careful..my forarms are a lil thick and i get c ut up.pretty good from the underside of the cowl). If dry there...get the car in the air and add start searching with ur eyes...cause anything else will be blatant... (ie oil pan or filter). Finally if none of those... well...

I was gonna run synthetic but I think it would make the leaks worse right now haha. I prefer using synthetic though honestly

it prob would... I agree. Do u know what was used before?

Cause if it was synth...u shouldnt really swap back to petroleum based... but if not...again, I agree with u.

I have no idea what they used before.
I don't think anything bad would happen if they both mixed though. I mean they do sell conv/synth mixed motor oil

I also forgot to mention that when I was doing the plug changes there was oil on the THREAD of the old spark plugs. Not the actual tip just the threads

Actually mixing synthetic and conventional is not a good idea. They additive chemistry is totally different due to the base oils being different. The synthetic blends are kind of a misleading name. They are more conventional than synthetic and they use a even different additive package. If you think it was conventional oil and you want to go synthetic, do a full oil change with a flush agent and then go to synthetic. After that avoid going back to conventional. I run Mobil 1 and it will "enhance" any leaks due to the nature of synthetic oil and the additives/detergents. I would try to track down the leaks, the timing cover to oil pan is a common one, and fix them. I would also pull a valve cover and see how clean or dirty it is up top. If you want to know what kind of oil and any contamination may be in the motor , I have contacts at oil analysis labs. I have had a few friends buy used cars and have the oil analysis done prior to any maintenance or mods. BTW I work for DuPont Performance Lubes and we deal a lot with synthetic oils (pfpe) and I field a lot of questions about motor oils even though we don't make them, yet. :-)

I did read it thanks for your help. Yeah that's exactly what's happening. Maybe it IS the speed sensors. They're about 80 bucks each At work (hub assembly w sensor)

Did you consider checking/cleaning the front harness connectors, and cleaning the rear sensor?
