take a deep breath, replace your tensioners while the mechanic has your car, and then enjoy your horsepower. You might want to replace the coils in whichever cylinder(s) is/are misfiring as well.

Talked to the mech. last night, he thinks there''s a baffle missing from a "flame trap" type of device. Several QUARTS of oil were in the airbox. I no longer think Nikasil is the culprit, which is a relief. I will keep you guys updated. Any one ever experienced anything like this?

PROBLEM SOLVED!!! It was the supercharger! Gotta have a new/rebuilt one, but other than that, she''s golden.

perfect man, glad to hear it.. ive no supercharger so I couldn''t tell you, but that doesnt sound cheap hah.. i''m guessing at least $1200? Wish more people owned jaguars around here, could definitely use a jag junkyard around to snag pieces from!

How much will your mechanic score one for?

My mechanic says 800, but I''ve found them myself as low as 500 rebuilt. I''m starting to second guess his diagnosis after talking to a few places. He wants 3k to do everything: engine tensioners and replace the blower. My reasoning in second guessing is that if the blower were bad, ALL the cylinders would be filling with oil. Not just the right bank. A supercharger rebuilder that I talked to says that the intake might be clogged, causing the blower to suck oil from the oil pan, or the headgasket might be blown. I''m starting to loose my patience with it. It does suck not having a lot of "seasoned pros" when it comes to Jags. BMW/Volvo/etc seem to have a bit more fanatics and shadetree mechanics to bounce ideas and problems off of. Perhaps I should have gotten the XJR with the straight-6 instead.

Trade it in for a BMW/Volvo/etc. and let the "seasoned pro''s"
help you. If no one has had your problem it is very hard to figure out what is wrong with the car. Whatever it is it will cost you its a Jag not a chevy

Well if you decide to do the tensioners (i''d do all 4) make sure your tech has the cam locking tools for that engine, mind didn''t. My local mechanic did both sets/guides/blades for $624 total in less than 6.5hrs total. I watched most of it, a lil time consuming, but definitely NOT an intensive job.

I dislike beamers cosmetically, I dig DB9s though...very sweet.

If gas permits in the next few years, I plan on purchasing a newer 08 XJ, Love them all around!

oil in airbox is due to excessive engine blowby which is a definent issue with Nikasil engines especially engines that have been overheated and not maintained properly
is the part load breather clean?

leaking cam cover gaskets are the cause of the oil in your spark plug holes
