Looking for a little help with my 88 XJ. My 173K 4.0 manual creates a fuss upon startup that sounds just like a (big) diesel engine for the 1st few seconds. The noise returns when engine speeds are >1500 rpms and when the oil warms up a bit. I bought the vehicle about 18 months ago, and the engine oil pressure had been running around 20 on the highway and 35 in town. Since the noise started, the pressure indication has been reading 15-25. Only white exhaust is being emitted from the tail pipe, and there is no burning oil smell in the fumes.
This noise seems to have just appeared following a full clutch replacement at the dealer. I had everything replaced; slave cylinder, pilot bearing, resurfaced the flywheel, etc., even replaced the rear main seal. I noticed some good oil leaks the next day and took it back to the dealer to check where the leaks were coming from, and evaluate the noise. They said oil wasleaking from the front main seal, valve cover and air filter housing after covering about 1/2 the filter. They stated that the engine was suffering a lot of blowby and just "tired", although they did not do any compression checks.
After doing a search on "oil pressure", I am not so sure that an engine replacement is warranted as of yet. I am going to replace the CCV tubing to see if that helps/solves anything. The noise only became apparent directly after clutch replacement. It is definately an engine noise, not related to the clutch. I also want to perform a compression check. Is there anything else I should concern myself with before looking at an engine replacement?
