4.2 Rear crank seal repair

[abowie]

GST # 11220 fits the rope seal groove & requires the crank to be ground down to Diameter 3.140" (79.75 mm).
It is the same seal used in USA to successfully solve the historic oil leakage problems in the Ford 460 engines.

Brilliant.

Who are you and what experience do you have with the XK engine?

Hi Chris...does the seal come pre cut in one place?....does it open up to fit over the crankshaft......is a sealer required where it fits into the seal retainer....anyone that you know of useing it in an xk engine....Thanks....Steve

This is probably a first, on starting my engine for the first time after rebuild I had a massive leak from what I thought was the rope seal. After strip down & fitting another new rope seal it still leaked. Fortunately this time I'd bench started it out of the car with an old bell housing attached for the starter mount. On removing the bell housing for further inspection my son noticed a trail of oil running down from the main oil channel plug at the rear of the block. The engineering works hadn't re-tightened it after cleaning. They had warned me to tighten it but I forgot! Tightened that and no more leaks.

On another note, I wonder why Jaguar changed the bolts, which hold the two halve of the seal housing together, to go in from the top. On older engines with only an oil screw the bolts went in from the bottom, so you could remove the housing without taking the crank out.

I am retired (more or less) but have a lifetime of experience in oil seals especially in higher performance applications.

With 30 years problem-solving experience in the oil seal industry I have lead seal developments which not only improve performance & reliability but also sort out the problems that other seals have created.

I still have all the right contacts so maybe I can be of help to anyone needing advice or assistance.

My old Company, Gregseal Technology UK Ltd is still operating in Southampton with my partner Richard in control of the stable. +44 (0) 7756 515 772.

The seal #11220 which we offer now for the Jaguar XKE engine was originally designed for the Ford 460 engines in USA & has eliminated the old oil leak problems.
Similarly for many other older engines we have applied similar design concepts with great effectiveness.
