I started have oil troubles after changing to a solid lifter cam with direct lube lifters. I ran a roller cam didn't have any troubles then went to the solid (imca) cam. I run a big block high volume pump with kevco 8qt pan with gates s****ers and tray in it. I seem to run out of oil at end of the straights and turn the oil light on. The motor has no oil restrictors in it. Its happend to 2 different motors and the only thing thats changed is the cam and lifters. I know it's holding oil up top!! I changed to std. big block pump didn't help the problem. Melling says big blocks move less oil then small block. So do i try small block pump with lifters I have or **** can them and go with reg. lifters. Thanks tim gardiner

I've never had that problem, but if all the oil is going up top, I can tell you what I do to remedy that. First off, I always look for ways to save money!!! With that said next thing is, NOBODY LAUGH!!!! I have always put pipe cleaners in my push rods. Put 2 per push rod. This was an old remedy, mainly for hydraulic lifters, but I am currently running it on a solid lift 388 without any problems. I'm sure someone has a reason for why this is a bad idea, but I have run it many, many times and my dad has been doing this for years and we don't have any trouble with it. If you don't know what I'm talking about with "pipe cleaners" I mean the little brushes you get to clean out a smoking pipe. You may just want to put oil restrictors in the block and a deflector or something over the rocker arms. But there's my 2 cents worth. Ok guys you can start the bashing LOL !!!

No bashing from me, lol. We used the pipe cleaners for years in our pushrods. I thought that was what they were "made for". You can clean a pipe with them, huh? Hmmmm, interesting...lol

Seriously, it sounds like the direct-lube lifters move more oil. Good for the cam etc., but bad to have an empty oil pan. I would try restrictors of some sort to limit oil to top of the motor.

If its holding oil up top then look for ways to let it drain back faster. Open up the drain holes in the block, and make sure teh engine is vented well so crankcase pressure doesnt hold oil in the top.

When you were running your roller did you have the drain back holes over the cam plugged or stove piped? Take them out if you did.Small block chevys have a great oiling system as is.You do not need a big block pump.Thats old school.Run oil restrictors.Check your pick-up to pan clearance and make sure your Kevco pan floor is not being drawn up to the pickup under high R's,especially if the pick up is too close.Honest! I have seen this happen.Some guys weld little spacers on the pick-up to hold it off the pan floor.Check the pick-up at the pump for cracking especially if you have bottomed the pan at any time.Oil level is lower in the pan at the end of the straights and if that part of the pick-up tube at the pump is exposed it will **** air instead of oil.The need for Direct lube lifters is questionable.I have never had a problem with flat cams unless someone is trying to run the roller cam springs.Roller springs are to stiff for flat tappet cams.OH! and once we did have a bad cam from the manufacturer.It had a hard surfacing problem and the man.warranteed it (but not the rest of the rebuild unfortunately).Pipe cleaners work but why go to the trouble. Just put in a set of oil restrictors.They cost less than 10 bucks most places and you can re-use them. Good Luck!

This oil problem has happend on 2 different motors and the pick ups been checked and replaced. Both motors ran fine no troubles till the cam change. I don't understand the oil overheating and running out of oil when a big block pump moves less oil then a small block so melling says. thanks keep going on things.

I have run the direct lube lifters and love them....i also had restrictors in all 3 motors i ran them in. I ran some pretty stiff springs and never had a problem with em eating the cam....and turned some pretty high rpm with em....
