Hey guys
I need some help with the oil line routing on my 1970 TR6R. i started up a fresh engine rebuild yesterday and of course looked immediately for oil returning, but there was none. I shut the engine off and drained the oil, then switched the oil lines at the steel tubes from the oil pump. i did have the outside line routed to the oil tank return, Would anyone be able to tell me if the outside line should be the feed line?

Did you add say 300ml to the crankcase? Do you have a filter on the return line?

If you start it up again I would hope the oil light would go out almost immediately, does it?

If you do a fresh engine build, or even the pump. The pump and oil system will want priming. Without having the engine running you can remove the oprv and kick the engine over (with the plugs out) until you see oil coming out of the oprv port. Once you have done this you have confirmed that the oil lines the correct way around and that within a short space of time the crank will be full of oil and feeding the big ends.

Did you assemble the motor with engine oil or engine assembly lube on the big end shells? Engine assembly oil is like treacle but stays with the journal until sufficient oil flow washes it away.
