UPDATE:  04-09-17 PM

The catalytic converter may have been restricting the exhaust flow.  The vibration from my flat spotted tires shook the ceramic honeycomb crap inside loose. I “fixed” it.  The engine seems to rev a little easier and I think the engine bay is a little less hot.  A ceramic coated header is near the top of my list for next purchase.

There is gear oil dripping out of the little rectangle weep hole at the bottom of the bellhousing. I assume the oil is coming out the input shaft seal.  So, I’ll be dropping the tranny and t-case.

The plugs look like they are running slightly hot and lean.  So I’ll be working on diagnosing a probable lean mixture problem.  Vacuum leak, Air Flow sensor, or O2 sensor, or ????... is it normal for an engine to run lean during break-in of  freshly rebuilt 22RE?

The resurrection of my truck after 4 years of storage has more unexpected surprises than I anticipated.


1986 XtraCab SR5 22RE 5speed W56B, ~26,000 MI after break-in, DIM (Did It Myself) rebuilt engine - .020" over, engnbldr RV head, OS valves, 261C cam, DT Header.
