My engine runs pretty nice. compression is even. I’d like to do
some preventive maintenance while it is out for clutch work. Front
and rear oil seals and a pan gasket are what I have in mind.
there is another component at the back of the engine ( according to
the parts book )above the crankshaft called ‘‘cover assembly’’
C.19687 part number. it has an asbestos seal C 19654? inside. is
this something that needs attention a leaker suspect?
I know the car has had oil leaks at sometime in it’s life. I
haven’t been able to run it yet other than a test firing so I don’t
know if it’s pumping out oil here and there or not. your
recommendations please.
Thanks in advance–

Steve, you’re able to replace the front seal and pan gaskets in
situ - pita but I’ve done it myself - but the rear seal is an
engine out job. More than that it’s a crankshaft out/block upside
down on an engine stand job, and even then it’s tricky achieving a
good seal. If you’ve got an oil leak it’s likely from the rear
seal - typical - but the fronts are also usual culprits. Go for a
new teflon seal in front c/w new spacer. Check the archives for
details.–

I just went through this myself…
I had a rear main seal, pan gasket set and borrowed an engine stand for the three day job. It should cost about fifty cents more.
Turns out the crankshaft has to come out.
To pull the crank, the front timing chain cover needs to be removed.
To remove it, and not take the great risk of damaging the head gasket or making it leak, the head must be removed.
One thing led to another… three months later I reinstalled a completley rebuilt motor, even put in new pistons and Rays EDIS. I’m sure glad the guy didn’t want his engine stand back sooner.

well guess I will do nothing then. I did notice there is a pretty
bad leak at the rear of the tranny, running out around the seal
setting on the floor.that could account for the oil I find. the cam
covers were leaking and I just noticed that the oil feed lines to
the cam covers have no washers on the banjo’s. that’s some big
leaks. maybe the engine is a virgin and is put together correctly.,
I can dream cant I, hahahaha–

I see the engine was running well and compression was good. That
tends to argue towards ‘‘if it ain’t broke, don’t try to fix it’’.
And when you combine that with the idea that once you touch one
thing, you end up touching its neighbor, you could soon end up with
a full rebuild like A rithmetician did.
On the other hand, some sub-systems can be addressed by themselves
without risk of serious scope creep. You can at least check some
things…assuming you can turn the engine upside down.
So, if you removing the pan anyway:
Consider pulling the oil pump and checking it for wear.
Replacing it now should not be too hard if it needs it. The
integrity of the oil pickup pipes could be checked too. Is the
pickup clear of debris?
You could pull a couple of main bearing caps and take a look
Same with big ends
Or just check the torque of them
Remove the oil pressure relief valve and clean in there. Access
should be pretty good
Check the end-float of the crank to see if the thrust bearings
are OK
Is the crank damper in good condition? If it ran well, I suppose
timing was good and the damper is good, but doesn’t hurt to look
closely at it
You’d hate to put the engine back and then discover any of these
things were issues or about to become so.
Another thought is what about components that are now more
accessible. Are the steering rack and steering column universals
OK and well lubricated, for instance?–

understood and points well taken. I am doing some suspension work
and all the hydraulics while the engine is out. planning to raise
it back in, hook up the cooling system and run it around like a
dune buggy for awhile. see how it sounds, check the oil pressure
and compression again. if there are any doubts not hard to drop it
back out and start the shipwrights engine rebuild. it doesnt seem
to be a high mileage car and those jag engines will run a long long
time. I had 160,000 and 260,000 miles on my two XJ’6s. this car has
20,000 on the clock with a broken speedo cable. I know it has been
off the road at least since the early 80’s. maybe longer. time will
tell. If I drop the pan I know there will probably be no stopping.
while I do not think it’s only 20,000 it is also possible that the
unscrupulous seller my friend bought it from may have wound the
meter back to make it look like a lower mileage car.–
