Does anybody have any advice.I just put some new edelbrock rpm heads,scorpion roller rockers on my 383.I ran the motor with the valve covers off and the right side has no oil comeing through the hole in the roller rocker until about 3500 rpms and even then it is a trickel.The left side flowes good except the first rocker has no oil coming through.The motor might have had this problem even before I put the new heads on I never payed attention,but I am conserned about the roller rockers not getting oil.Any advice is greatlly apreciated.

Are your pushrods old? They could have a sluge buildup inside restricting oil flow. Thats how the oil travels up to the rockers so it would be my guess.

The pushrods are brand new also.A tech at edelbrock said he has seen this before and it was caused by the distributor not being fully seated.I did check and the dist is all the way down.Any other ideas?

I'd agree with the thought that there's something wrong around the distributor. The valvetrain on the right side gets its oil from a passage that goes through the distributor hole in the block, with the lands in the distributor shaft housing forming part of the passage. If the distributor height is too high or too low so that the lands don't line up properly with the block, then oil won't get to the right side.

I just bought some motor flush,I will try that and if that doesnt work hopefully the new distributor Im getting for christmas will make a differance.

this may seem unnecessary but did you happen to prime the motor to see if oil was flowing before you decided to start it?? its just something i always do just to make sure.. because my first motor went because of an oil problem.. before i install anything into my motor, i always clean it with solvent and shoot compressed air through any holes..

Yes I primed the motor when I first got it.It has about 40k on it now.I ran some motor flush through it today and it did little to nothing.Another thing this might be unrelated but when I reinstalled the dist after doing the heads I set the timing and the vac advance is basiclly touching my edelbrock rpm manifold.I set the timing as I always do 16 base 38 total timing.I dont recall if the distributor was truned that much before,I dont think it was.Any other ideas???

if you can see the oil at 3500 RPM you have less oil at a lower RPM you can't see. i suspect you have no problem at all. i'd also suspect you've run it enough to trash any parts that needed oil that weren't getting any.

1320-camaro-383

Do I understand you correctlly?You suspect there is no problem yet you also suspect I trashed any parts that need oil that was not getting any?If there is no problem how could I trash parts?WOW thanks for the insite.

I believe ede meant that if you truly had no oil pressure, the parts would be destroyed by now. I can remove my valve covers with the engine running at idle and not loose any oil. I have no abnormal noises, 80psi on a cold start, 60psi at 2000rpm+ cruise and 30psi hot idle. If you don't have any unusual noises, just drive on.

1320-camaro-383

Maybe your right,I might be reading too much into it.My oil press is good at the gauge.60 psi cold,30 psi hot at idel and 50 at 2k rpm.I have a ton of cash into this motor and would hate to a roller rocker break sending the bearings into the crankcase.I know it doesnt need much oil I just cant understand why the drivers side is flowing like a river and the pass side is only flowing about 1/10th of oil as the drivers side.there must be a reason.

1320-camaro-383

Ok well I replaced the dist like the edelbrock teck suggested and it did nothing for my oil problem.On the brite side I now have a shinny new dist.I did notice in addition to the pass side having low pressure both the right and left rockers in the front of the motor are not getting any oil through them regardless of rpm.Could it be bad lifters?I tend to think not because the drivers side back 7 are flowing like crazy if it was bad lifters I dont think those 7 in a row would all be fine.Any other advice?
