Re: 93 XJ low compression, what are my options.
I would start by pulling off the plastic line that runs to the rear of
the valve cover at it's manifold end and see if i could blow through it
into the valve cover. If I couldn't blow through it, I would know the
'mechanic' was a liar trying to sucker me for a new engine.....
That line can be cleaned with carb cleaner and the rubber grommet's hole
can be cleaned with a paper clip. In some cases, the valve cover has to
come off to get the sludge out of the grommet's way.
Other than that, I would want to verify just 'what' was causing the low
compression. A wet test can tell lots, so can a leak down test.

Re: 93 XJ low compression, what are my options.
There you go again, from the biggest loser of them all! The jealous,
really jealous, I can't believe how jealous this little draft dodging coward
schizophrenic psychopath liar hiding in Vancouver via
S0106000ea6ba70e7.vn.shawcable.net 24.86.24.251 intrepidator@shaw.ca who's
only way to get attention is to make a fool of it's self. With an obsession
with perverts and goats, where it writes via remailers, and cross posts to
other perverts to no one's surprise. With extreme jealous ranting over my
documents, possessions, successes, manliness and super Southern California
body. Committing forgery over many of them proving I'm a responsible
American man. You remind me of a little rat dog, like a Mexican Chiwawa with
it's senseless barking, me too, me too. You're even more senile than I first
thought. And the poor thing, you're too girlie to take responsibility for
yourself again, by signing your statement like a man.
You're not worth any more time when a cut and paste this same paragraph
it fits so well!
God Bless America, Bill O|||||||O
