Thread: Small block race motor odd problem

Tweet

i have thought about that screening. I plan on pulling the intake off this week and yanking those screens out. But due to the way the problem was, i am still thinking something else. it sat for a couple minutes when i came off the track. when i fired it back up it still had zero pressure. the motor was 180 deg, so the oil was plenty thin. it should have had plenty of time to drain back to the pan. I have been running that expensive synthetic oil in it due to the problems. I dont know how much longer the budget can aford to dump $50 worth of oil every week. My next option is to yank this thing out for the back up motor. I would really hate to do that. This thing flat screems. if this motor wasnt so damn good i would have yanked it out weeks ago. but i want to work this out now. Keep the ideas coming please. and thank you for the replies so far. This message board seems active with some sharp guys.

its one of the Moroso HV race pumps. the one that was on it before was a Melling HV pump. being honest here when you set the $29.95 melling pump next to the $79.99 Moroso pump visually they look identical. Casting numbers are even the same. when you tear them apart you can see that Moroso Deburs everything and changes the bypass set up. Keep in mind 2 pumps, same problem. both were new.

i appriciate the ideas you have. and i think your in the right direction with your thinking. The spring in front of the plunger is a good idea. I may try that one. This is in an IMCA type Modified, and pulling the pan is a breeze.

your secret is safe. I just want to keep that thing on the track so i can throw more mud at the guys behind me. those hoosiers really fling it!! I am hoping that one of these fixes cures my woes.
