Oil/Coolant Leak Into Manifolds?
Need some gearhead expertise here. I have an 89 YJ 258 that has been converted to TBI.
Back in July of last year, my carb sucked the air cleaner hold down nut in. I found it on top of the #2 piston. Did some cleanup and reassembled with new gaskets and such. The manifold nuts and bolts were a real sucker to get at. Anyway it was a successful repair and I drove it until about November when I did a tear down restoration.
Well I got the junkyard tbi installed and the engine running. Running surprisingly well. But after 2-3min of idling I start getting white smoke rising from where the manifolds mate to the head. As if there is about 4 cigarettes lit and burning inside each port. And even some from the exhaust pipe where it 90's around the oil pan. It is not burnoff, I have run the jeep a few times now. With the jeep running, we found a leak here:
