I've been struggling with the 90 XJ 4.0 Ltd I bought a while ago with almost 200,000 on it. Got it checked out by the local stealer, who gave it a clean bill of health. Almost $2000 later, I got it to pass it's emissions check (and fixed a few other things including rear main seal, cracked manifold, water pump, 02 sensor, injectors, all the HT wiring and vacuum pipes, track rod and more). But it's still doing ~10mpg, has low oil pressure which I've sort of managed to "fix" by running 20/50w, and has developed a significant knock which I'm pretty sure is the big ends (fairly loud at idle, quietens down under load). Last thing I just discovered is that cylinder one is running at about 80psi, whilst the others are between 110 and 130.
Whilst I'm quite enjoying the wrenching, I'm getring fed up throwing money at it, and I consider myself to have three options: -
1) Cut my losses and sell it for peanuts with the remaining problems.
2) Replace the big ends, mains, fuel pump from below, and at the same time replace the rings (assuming there is a small enough ridge to get them out without going beyond my comfort factor) and also throw on an exchange cylinder head. I'm comfortable doing this myself, and recon onit costing about $500 all in.
3) Replace the engine. I'm not comfortable with doing this, and think the cost to get my local independant garage to do it for me would be about $2500 all in. Of course, the vehicle would be worth more with a new engine in it....
Advice needed please - and as soon as possible, cos if I'm going to go with (2) ... which I'm leaning towards this will be done during my two week break at Christmas.
