Sky High Oil Pressure

On the Standard engine this is a relatively easy job to fix and involves unscrewing the top spring-loaded bolt head, removing the spring, and checking to see if the 'bucket' type valve is free to move. Watch your eyes, those springs can jump if you don't watch 'em!!

Never attacked a Continental so cannot comment, but would suspect same problem - someone here has probably removed the PRV assembly on one of these.

If you have a shop manual, read that first before approaching filter body with spanner/wrench.

DO NOT adjust or unscrew the PRV setting to 'adjust the problem out'. It won't help and will damage your engine eventually.

You will have to do this to get access to the PRV, which is a ball bearing about 5mm across. This is the bit which may be stuck in position, so when you hit 15psi, the ball bearing doesn't lift from its seated position, and dump the excess oil.

To make life easier, measure the distance from the top of the screw to the lock nut BEFORE you unscrew everything, then you can get a good approximation to the original set-up when you reassemble the PRV assembly.

Hope this helps.
