:!:
After 3 days not a single droplet, not even after warming up, only a few drops of oil fell down when priming the Morgo.
And much more when the pressure relief valve of the Morgo opened!

My Ariel SQ4 screwdriver knowledge is finally getting better :!: :oops: :mrgreen:
Of course I can't say yet whether the balancing was really worth it, but "felt" for me it is of course much smoother now (but may be also the correction of the valve timing).

I could do with your recipe, Rudolf!!

I suspect the same goes for many of us.

The main problem with my SQ4 were the rubber hoses from the oil tank and filter to the engin connection. Over time (and PO) these have become different dimensions (metric, imperial) and have also aged. My recipe was to loosen these connections, to clean them (with brake cleaner) and then to treat the tubes with this black (heat resistant) goo that I had left over when assembling the cylinder head gasket.
When you push the rubber hose onto the tube, a lip forms that I haven't wiped off. Then let the silicone harden before oil gets into the system.
So I did it with all the seals on the joints.
Hope it lasts.

Thanks very much, Rudolf.

Was it Well-seal you were using?

Well-Seal is certainly the best, but I simply used the silicone gasket goo (called BondLoc) that the Drags sended to me with the Otto head gasket.
