So - more extreme project creep! :D

The early cam housing covers are renowned for there capacity to leak so, as usual, I've gone for an extreme solution :lol:

This is a casting I've had made which I hope will permanently cure the problem:

After machining I've bonded it to the original cam housing:

Clearly I've copied the SE's approach to providing a flat surface to seal against. Time will tell how good the one-pack heat-cure epoxy is!

The eagle-eyed will also have noticed my new oil pump design:

Image

The oil pressure relief valve (prv) doesn't work as well as I'd like - oil bypasses it even at 20psi, so I'm running an external, adjustable prv with bypassed oil returning to the sump - not the inlet of the oil pump.

Feel like I'm making a bit of progress at last :D

Crikey Pete - you're going to a lot of effort to ensure your chassis doesn't get covered in oil like Stu's - you do know that your chassis will now rust and all bolts will seize in place? :lol: :lol:

Superb engineering as usual.

Amazing stuff. Especially interested in the oil pump mods. Most of us worry about oil pressure and flow. Can't wait to hear more once up and running.👍

Cheers! I've tested several oil pumps and the only one to work as I would expect was an early Jensen Healey pump. These early pumps didn't have the loose-fitting steel sleeve in them. Because the sleeve is held in place by the spring-loaded shuttle the minute the shuttle leaves its seat oil starts bypassing the assembly - this happens at about 10 - 15 psi and because it's easier to pull oil from the relief valve than the sump it's my belief that that is what happens - oil is pulled from the bypass by the suction of the pump inlet side. By letting bypassed oil return to the sump this won't happen. Well that's my theory :D

I'll post up a picture of the external prv/thermostatic remote oil filter head assembly.

Next up - cam position sensor to allow sequential fuelling/ignition.

Is that a little over spill of sealing compound on oil pump housing?
