engine swap?

[Salvagedcircuit]

I hear your frustrations. I have a rebuilt gm 4.3L vortec V6 in my astro van from jasper. Its been about 15k miles and for the past 5k miles there has been very tiny amounts of metal filings in the oil filter. Again, brand new rebuilt engine. Took the oil pan off and inspected the engine. Turns out the piston rod caps were not torqued down to GM spec. I removed the rod bearings and they had signs of uneven wear. Purchased all new mhale rod bearings, used plastigauge and my calibrated torque wrench and torqued everything up to proper gm specifications. It's crazy what some companies get away with.

 

Please don't crush the comanche. You will get more by reselling it. There are folks who buy comanche's in any shape. You will get more from a private sale than any junkyard will offer.
