Is the windage tray on my 383 Magnum really necessary for street use?
71 Power Wagon 4WD, small torque cam, street use mostly & maybe a little off road use. I'm installing my 6 qt rear sump pan for the 4th time due to leaks & got some Milodon pan bolts that are a little shorter. It'd
be a lot easier to install the pan without the tray, so if I ditch the windage tray, will I loose power or mileage?

Tray is not needed for low rpm street use. For a truck, you will never see a difference without the tray.

Thanks & that helps seeing I just installed it without the tray.
My main concern was if stirring up the oil on the crank affects
gas mileage, since I'm planning a fairly long trip with the truck.

If MPG is a concern .... I would consider putting one on ... if it is not that much of a PITA. The TRAY does a decent job pulling oil out of the crank swirling around ... but not as good a scraper would.

That's what I was thinking & during a search on this site, I read
the MP tray isn't that good unless you drill holes for drain back.
I have a 6 qt MP rear sump pan & wonder if the tray is recommended
for that application. First time I made a gasket with Permatex &
think I got way too much on there, so am pulling it off this morning anyway.

If your up & running I'd let it go as is & put your energy elsewhere . The MP drainback could be an issue if racing but not significantly in your app. The tray/extra gasket changes pickup clearance so might see what you have just for reference if you do go back in there.

Thanks Robert & I just pulled the pan off. Thought I may have applied way too much gasket maker & sure enough, it would've peeled off into the oil. The gray takes quite a while to harden, so may just use The Right Stuff. Drilled 6 3/8"holes in the windage tray for drain back so may as well install it. I could use the rubber gaskets with sealant or adhesive, but there's some small imperfections & scratches in the pan flange, so think gasket maker is the way to go. Messy, but hope it works.

I put the Mopar truck pan on the Dart (383). Fits great with the Alterktion suspension. I used the MP tray too, put some holes in it and chamfered them a bit.

I typically put a thin coat of gasket maker on the gasket itself. Just enough to help it stay in place and fill any small imperfections but not enough to make a mess.

Well, finally got it done. Drilled drain back holes in the windage tray & used the Right Stuff as a gasket. Took a few 'practice runs' to make sure I didn't smear the gasket maker (tight quarters), but got the tray & pan torqued down. Probably used a little too much silicone, since it oozed out the bolt holes, but I can live with that if it's leak free.
What kind of gaskets & gasket maker are you using?

Typically the "form-a-gasket" from Permatex. There are two grades of the stuff, I need to see which one I use.

Like I said, I use the cork gasket, I just skim it with the form-a-gasket on both sides. It has always worked for me. Lots of guys get away with no gaskets, but I typically use gaskets, just my preference.

BTW, I have truck envy, that is awesome!

Thanks much & what type of gaskets are you using, rubber, rubber/cork or cork?

that is an exceptional looking truck. If you cant get the pan to seal (4 tries & counting) you may just have to sell it to one of us. Put me at the top of the list

Just found out the REAL cause of my oil pan leaks. Put new oil in & let it idle for a while & viola, no leaks. Happy camper until I got back from a 30 mile freeway cruise & saw oil dripping all over the front axle. Found one loose pan bolt...and got to thinking why my PVC hose is plugged into the back of the Eddy AVS carb. Sure enough, soon as I switched it to the front AND cleaned all the oil out of the valve cover breather & took it for a ride, NO leaks. Didn't know I had that much ignoramus in me. 4 pan gasket replacements, a $110 Jegs windage tray & $90 in oil, all because the PVC hose was plugged into the wrong inlet.

Its this nylon tray with integral gaskets on both sides.
Pretty trick, but tore it when I had to remove cause of leaking.
Probably would've worked just fine, if I the PVC was hooked up right..

That's good it is solved. Clarify this for me, the PCV hose got moved from what port to what port. I'm not grasping what was changed & how that stopped an oil leak at the pan?

The carbs pulls more vacuum off the front inlet than the back. On their site, they say plug the power brakes in the back port & PVC only on the front. My carb builder also verified that it pulls more vacuum from the front side. Here's the Q&A from their site:

Q: Can I run my PCV line to the rear of the carburetor?
A: We do not recommend routing the PCV line to the rear of the carburetor. We recommend that the PCV line go to the front, if you have power brakes, they go to the rear.
