Oil starvation issues SBC HELP?

[joespanova]

OK Carl.....thats why I'm asking here. I don't do it for a living.
Bleed off is a good point. I'll definetly look at the cam bearings , lifter bore clearance and rod side clearance. I can't change the side clearance without ordering new rods , which I'm not.
I will buy a good pan if ness.

BTW.No one has referenced an accumulator AT ALL.
Why not? In theory could work.

You might look at 10552C pump would be a better choice at that kind of RPM.


Side clearance is not a factor in bleed off, I have build piston guided rod engines with .115 side clearance and no issues.

Its bearing clearance which regulates the amount of oil bleeding out between the rods.

Jake Stelter engine won Drag week 2 years in a row had some issues and was correct with a pan and pump. He is on F/B and might be of some help.

Good luck only trying to help.

If you have everything else right,you should not need it for what you are doing. Read Mike Taylor's post.

I know you are............and I thank you all.
I'm using the 10552c right now.......I 'll look at the thread.

It won't fix the problem, just mask it.
Did you check bearing clearance yourself, with a bore gauge, or plastigauge?
As mentioned, aluminum rods grow with heat (any) and the bearing clearance will grow with it.

Bore gauge.........set to the rod journal.
I'll go .002 if it'll help at this freshen up

If your using a cheap bore gauge with rigid fingers your not going to get a correct clearance. Not to many guys can afford good bore gauges to check bearing clearances.

Here is a thread on different bore gauges.
