Since last post, I focused mainly on priming fuel system and oil distribution ; and thanks to good advices I received on the previous posts, everything went OK :
*Fuel : I installed dummies tanks ( Definitive parts still to build!) with 10 liters and 5 l plastic cans ...pick up at the very bottom, and return visible from the opening .The carb is not yet connected and 100 % goes to the regulator return line .
After 4-5 s priming, the fuel pressure stabilizes nicely at 5.5 psi ; switching
( 2 x 3 ways valves) on the other thank takes 2-3 s and pressure is the same.
As expected , the Carter 4601 pump is a little bit noisy ....
*Oil system : I finally decided for 15W-40 mineral Schell Helix oil, with ZDDP additive .As visible on the picture, I made a removable bracket which holds a 500 W electric drill ; I use the original belt , disconnected from the cranck pulley , to the drill pulley.
After 23-30 s initial priming the oil pressure goes up to 75 psi and keeps very stable .I suppose that it is from pump pressure regulator action ...
I operated with cold oil , and as expected , TOM, the electric drill came to eggs coocking temperature by the same time! But still working ...
The valvetrain got lubed in sequence and I made the 90 ° rotation procedure.
I decided to make the first starter rotation test : OK, without, and with the spark plugs .
During those sequences , I noticed that the lifters bleed-down within a few minutes , and not all at the same rate ...
Is it something I should take care of and investigate ?
From a few Web investigations, I did not found a precise answer...
