This is slightly off topic since my project is a Porsche 914 with a Rover 3.5 conversion. However, I hope to redeem myself by the fact that I've got a TR8 - I LOVE those engines.
Anyway, I'm priming the oil pump on my Rover 3.5 and I get 35 psi with my
electric drill. This makes me happy but I'm getting almost no oil to my rocker
shafts. At the front pedestals I get a VERY slow weeping of oil, almost nothing
at the rear. However, if I loosen the pedestal bolts oil comes gushing out like
crazy. I switched the shafts from side to side, reversing the ends. Same
thing. FWIW, I'm using Rover 4.0 heads and valve train.
I know the rocker shafts are designed for left and right installation, but for
the life of me, I can't tell the difference between them. Looking at the
pedestals that mate up to the oil passages, there are recesses that match the
holes, but no holes that actually lead up to the rocker shafts. The only way I
can see for oil to get up to the shafts is through the mounting bolt holes.
Since these holes are a tight fit with the bolts there isn't a lot room for oil
to get up there, especially when the oil is cold and thick (15w-40 in a cold
garage). Would I see more flow when the engine and oil are warmed up?
So, my question is, how much oil should I be seeing at the rocker shafts?
Thanks.
