Apparently the oil leak os not fixed. I thought it was the back of the valley cover took it off and retorqed it Diana nd out everythinf back together and still leaking like crazy. This thing never leaked a drop before the dod delete and can swap/ turbo install. Its gotta be something I messed with injustice don't know what it could be.

Checked the oil pressure sending unit? How are you feeding your turbo? Clean it up good put some dye in it and hit it with a uv light. Should track it down pretty easily.

I agree ^^^^^ clean everything! esp around the turbo feed and drain. fire it up with a piece of cardboard or a old sheet under it. let it run until you can see where its leaking.

Thanks guys! That's the plan I'm gonna tear it back down and put a new valley cover and gasket on it. I tapped the pressure sensor for the oil feed line and I think that may be the culprit as it only leaks when oil pressure goes above idle. Then I'll run feed off the adapter for the oil cooler lines like everyone else does. Getting fancy bit me here. I'll clean everything up while I'm in there and hopefully that will do it.

Put a new valley cover and gasket on it and the leakis gone thank god. Back ti getting this thing dialed in. Its running pretty good are 9lbs so we are about to start turning it up. Biggest problem is getting time to actually drive it and run logs.

Another note I'm looking at picking up some racestars. What's everyone running up front 17x4.5 or 17x7. Not sure which to go with. It sees a bit of street time. Just wondering if the 4.5 wheels are strong enough for normal street driving

I run the 17x4.5" racestar on the front of my truck and have driven it as far as 4hrs away to the beach a couple times and no issues with it. I drive it alot on the weekends and i can hardly tell any difference over the 17x7 that i ran first.

Thank you for that feedback. What size tire are you running on the front?
