My 46 E series starts at close to 100 then drops after a few minutes to 70psi. I reco'd this motor last year but before that it was quite happy to run aqt around 35-45psi.

The figures quoted by TribalElder are excessive for both the Series E and earlier UB engines, indicating either that his gauge is over-reading or that the pressure relief valve is u/s, or both. The pressure relief valve should open at 60psi., therefore pressure should never exceed that figure. 50psi. at start-up and 20 at idle suggest the engine is in reasonable condition, but of course will be affected by type and grade of oil and ambient temperature, etc.

The pressure relief valve is there because the plain bearings of these motors, especially the white metalled big-end bearings of the UB engine (1934-38 Eights, ie. 35/Series I/Series II), neither need nor were designed for very high pressures. With a newly-overhauled UB motor you could expect 50-60psi. at fast idle after a cold start and, once hot, 50-55psi. at 40-45mph. and 35-40psi. at idle.

These motors operate quite satisfactorily at somewhat lower pressures, but less than 25psi. at the above cruising speed is becoming rather marginal, in my experience.

A new update for you all:

Hi a couple of more pictures here, the body is now stripped and etched primed ready for welding. I've started work on the chassis, i will upload some more pictures later on.
p.s. I'm in need of a brake master cylinder, if anyone could help? Thanks.

Peter, you state that you need a clutch master cylinder. Unless someone has, at some point, fitted a hydraulic clutch system you don't, as they are mechanically operated, mate.

Clutch pedal is affixed directly to the release-bearing shaft on the gearbox. If you need any of these components let me know as I have loads of spares.

Perhaps you meant brake master cylinder? In which case I regret that I can't help.

Hi you are correct it is a brake master cylinder I need not a clutch master cylinder thanks for the message

Hi, I know it's not local but Ian Harris sells them in the uk,

This is an update on my Morris 8 series 1, suspension all welded and painted, ready for the rebuild now.

Looking very good.
I presume you did an alignment check and a detailed inspection for cracks ? These chassis are notorious for distortion and cracking.

Peter,

Did you do the chassis repairs yourself or use a specialist?
