Thread: Oil Pan; crank scraper? windage tray? I'm confussed!

Tweet

....Hello Everyone, I'm in the process of having my 413
small block rebuilt & decided to go with a 7 qt. oil pan for increased lubrication. I'm looking at the Moroso pans and I'm not sure if I need some of the following options; a) windage tray. b) crank scraper. c) oil pan baffles {or do all pans have these?}. d) trap door &/or swing door baffles.... I'm confussed! Not sure what info you need but it's a '32 Ford with 500 HP, street/strip car..... Thanks a bunch Please ask if you need more info.... Bill

A crank scraper and windage tray are both designed to help keep the oil in the pan and off the crank. Baffles and trap doors keep the oil in the pan closer to the oil pickup and prevent the oil from sloshing around and running away from the oil pickup under hard cornering or hard braking conditions.....

dave is right but let me add, if its for the st. i'd use the big pan, but you dont need all of the trap doors. they are made for HD racing. windage tray yes.

....Thanks guys I'll go with one that has a windage tray...... Bill

You mentioned strip use in your first post which would support the need for baffles around the pump pickup to ensure oil presence upon hard acceleration. Dave is correct about keeping the oil from the crank rotation elements, the main reason is to keep them from whipping air into the oil. Air bubbles don't lubricate as well as oil does. A bigger pan doesn't necessaryily mean increased lubrication, there's only so much space in the bearing clearances for example, what it does mean is that there's less chance of oil starvation, especially if you're going with a high volume pump, and greater opportunity for additional cooling.

Thanks Bob , I was going with a Moroso pan with only the windage tray but Hamberger has one that I liked with windage tray & baffles so I'll go with that one.... Bill

i have been reading up on the crank scrapers, how come these are not installed on vehicles from the factory ? especially the high performance ones?.. seems like every engine would benefit from this, or is it all just a bunch of hype and only the -9 sec machines need them ?

That's one more example of being more expense than its worth. On a stock engine in normal use, you'd never notice the difference. It's only when you get crazy, like we do, that they pay off. You have to realise that the factories don't have the time to fit such esoteric goodies in all the varied engines they build, for very little return.

i like the milodon is a better pan the the low buck moroso are a over lap on the added sump and mig weldded there is a lot of what i call( pop corn) in them from the mig welding (spatter) if you do not find it all the oil pump will . that is why i like the milodons all tig welded and there diamond stripper windage tray and use one of there side kick out oil pans and call it good the more stroke you have the better is stuff need out be that and rpms

....oh, the pan that I finally ended up using was a street/strip one that was make by Champ..... Bill

....oh, the pan that I finally ended up using was a street/strip one that was make by Champ. I remember that it had a windage tray..... Bill

If you get a Hamburger oil pan it does have scraper and windage tray built in.
