    Question to all you Jeep Experts?

    Update! Hope everyone has had a nice Christmas and has recovered from New Years! After almost 2000 miles since the engine work, no leaks, only re-torque required was the connection between the header and the rear mini cat. Engine is running smooth and quiet! There is still the persistent...

    Question to all you Jeep Experts?

    Oh no! It's on my mind completely. I will spend the next couple of months searching for a 4.0 and a 42RLE transmission in a local junk yard then spend a few months rebuilding both. I have already begun to accumulate the parts to overhaul both. Then do a swap!

    Question to all you Jeep Experts?

    All back together, running like a champ. Out on the highway easily accelerates to 80+ MPH. Will take it out for a 200+ mile run later in the week. I think there is still a hint of knocking which I think is the crank moving fore and aft due to the wear at the thrust bearing. Thank you again to...

    Question to all you Jeep Experts?

    Never any 02 codes, not a one! During all of the different codes being thrown, only one time a PO175 appeared. No exhaust related codes. Cam lobes all look good. I'm thinking that the springs being compromised were not closing the valves fast enough at the higher RPM and power settings? I...

    Question to all you Jeep Experts?

    I did Terry. Ordered through Amazon, free shipping! About $552.00, from the mini cats to the tail pipe. Local exhaust shop quoted $1100.00. I found that removing the left from wheel and accessing the bolts through the inner fender was pretty easy. With all that I have just done, I think...

    Question to all you Jeep Experts?

    Good morning, Are you familiar with Jeep Service Bulletin # 09-003-03, dated Aug. 1, 2003? I can't figure out how to attach a document here!! After reading it, I think it's my issue. As I don't own the $400.00 tool they reference , I will just pull the head inspect and de-carbon the valves and...
