Hey guys! Recently did my oil pan gasket trying to chase down an oil leak. Its leaking less! but still leaking lol. Planning on doing my Valve Covers to update them to that new built in PCV style, along w/ the gaskets, and my intake gaskets as well (in hopes that will help my MPG, ik my big tires don't help that problem, but I posted maybe a year ago and came to the conclusion my fuel trims are way too high in both banks and just never got around to fixing that problem due to life). I definitely should have started high for the oil leaks as I'm noticing quite a lot of oil build up on top of the valley pan, kinda near the throttle body. Should I plan on doing the valley pan gasket while I'm there? Knock sensors? (No engine codes showing, worried about messing with them and having more problems). Want to get everything I need done and not have to circle back. Just rolled over 200k.

IMO, it only makes sense to do the valley pan/cover and the knock sensors, if you can't stop the oil leak by changing the valve cover gaskets first.

Take a look at the oil pressure sensor on the back of the engine, on top, behind the intake. Hard to see and really hard to change, but it's due to fail or start leaking.
