I like Allen G and NicKl , i dea,s as i need to try and flush my engine with oil after 40 years of standing oil in the engine. As well as the primary and trany, Pretty much need to start with the engine. It has compression, oil tank flushed, new oil lines. ready. This a 67 engine with no oil pressure light, Without any indication. I,m reading every thing i can how to start this engine up again with providing a way to give it a good oil prime before it gets to run. My plan is to pull the sump plate drain what is ever there, reinstall refill with what ever i have, drain again, Then refill with ( any good suggestions?) Then Install vinyl clear oil lines for supply and return and with spark plugs out try to see any movement in the clear oil lines while kicking it over. If not I,m thinking of pulling the primary cover and turning the crank with the alternator nut useing a socket and drill or impact driver, I,d rather not try this if i can use the kick crank first but unsure which weight of oil to do this.
Other then useing temporary clear oil lines to visually see oil flow I,m out of idea,s with a engine that has not been started in 40 years which had a complete rebuild 1500 miles then . Kinda squeamish about useing the alternator nut as a drive as well. For sure the OPV and pressure to inlet line procedure makes sense but what oil weight would be best for the prime. I,m thinking 10 weight or less?
I had the cylinder head off my engine when I was turning it over using a couple of nuts locked on the drive side crankshaft threads (rotor position) and a socket and speed brace but I’m sure it would work just as well with the head in and spark plugs out. I found it a very easy and convenient way of turning the engine over and you really don’t need to go too fast to get the oil moving once the oil pump is primed.
I did think about using a drill to turn the engine over but my worry was that if the thing wasn’t held absolutely true and it snatched at all then I could cause a bit of damage to the crankshaft spigot and threads? I felt more in control and safer with the speed brace.
Allan is spot on about the return side and I already had the gear in place and plan to do what he suggested. I will have a short flexible extension pipe fitted to the sump pick up pipe and this will be submerged in flesh oil in a plastic bowl underneath. Once I see the oil coming out of the return pipe in the oil tank I will block it off until I see it flowing out of the pipe to the cylinder head. Once I’m happy that everything is primed and full of oil this way, everything will get put back together.
I’m using Morris Golden Film SAE 20W-50 for priming everything and once I’m ready to head out on the road I will drain the tank and sump and top up with Morris Golden Film Running In oil, as virtually everything in my engine is brand new.
