|Oil Sump Drain Valve|
I then began to fill the other oil chambers including the one below which lubricates the shaft used to move the camshafts axially.
|Oil Filler (and Emptyer!)|
I loosened the filler hole support and cleaned all the mating surfaces which should provide the seal. I then slapped (technical term!) a load of Heldite on the surfaces and screwed it together again - tightly.
After a while, despite considerable care, I refilled the oil and ... you guessed it, it was no improvement from before and now there is the Heldite in the gap also around where the oil is leaking.
I'm forming the opinion that this was perhaps not one of Sentinel's best designs unless there was originally a gasket present.
Looks like I have an extra task ahead to make an almost cylindrical gasket to wrap around the joint; otherwise, oil consumption will not be a strong point!
