Finally got the 2000 4.0 back on the road after a series of delays. New head, cam, pumps, thermostat - and it fired right up on the first try. Ran at 1500 rpm for 10 minutes per advice of machinist to help cam and lifters get acquainted. Then drove around town gently for a few miles. FSM says...

Getting close with my rebuilt 2000 XJ. Engine is in place, now trying to ID all hoses, wires, clips, etc. before attaching accessory drives and manifolds. There is a small bolt thru-hole on driver's side of engine-to-bell-housing joint just below the CPS that has me stumped. None of the many...

Ready to install my 4.0 after overhaul for cracked 0331. New parts include: pistons/pins; rings; all bearings; cam; lifters; oil pump; head [J&C]; head bolts; gasket set. Crank needed a light polish, and cylinder hone was still good. Old pistons were scuffed and oil pump intake screen covered in...

13-2 of FSM begins, "(1) Remove the rivet attaching the end cap to the air deflector." It ends, "(4) Install the rivet attaching the end cap to air deflector." Are the rivets on the front bumper assembly one-time-only throwaways, or are they designed for multiple use? If the latter, can...

Search of all tech forums yielded mention of "factory tow hook brackets". Looking for a way to mount a front hook while retaining oem bumper. front fascia, etc. First use of this hook would be towing the XJ from my shop to another that is equipped with a lift so we can more easily install the...

Getting ready to replace or rebuild the injectors out of my 2000 4.0. Local parts discounter is $50 for Ford, $51 for Jeep; only $1 less for reman's. Nearest F.I. services are for diesel only. Are there better prices out there? tia, summit94

Have removed 4.0 from my 2000 XJ. First glance reveals no obvious explanation for coolant in oil, but there was lots of sludge almost totally blocking intake screen for oil pump. Hmm, could this have been the reason for low oil pressure? Crank, cam, pistons/rods and block are going to local...

As feared, the B-stone analysis confirmed coolant in oil with "excessive bearing wear" on the 2000 XJ. After a few hours over on Jeepstrokers [Thanks, J308] it seems that paying a local shop to build up a decent stroker from bits and pieces could run at least $3000, probably more. That leaves...

Hi, folks, new subscriber summit94 here. After 18 months/12k miles ownership of a cherry 2000 XJ Sport, symptoms of terminal engine disease are developing. When purchased, max. hot oil pressure at 2000+ rpm was a steady 43 psi; hot idle a steady 13. For the last few months those numbers have...
