. I'm sure this has been asked and answered many times before. I bought a new one piece windage tray with reusable gasket. The old tray with 2 gaskets leaked after 4 years. After making sure the rails were straight on the pan, I installed the new one. I fired it up, let it run for 15 minutes, no leaks. I drove it 2 miles did what I had to do, checked under the car, no leaks. Drove home, parked it in the drive which has a slight incline. Putting things away in the garage, look at the car and there's a small puddle of oil at the back of the pan. I pulled the inspection cover, no oil in the bell housing. No valve cover, oil pressure fitting or any other leaks. Should I just drop the pan and silicone the son of a bitch on both sides. I was hoping this would eliminate that. My thinking is maybe the oil puddles in the tray and can't drain back in the pan. I know this is long winded but maybe someone else has dealt with this and can give me some insight. Thanks in advance!
 
I just replaced my oil pan gasket last weekend. I'm still leaking, too. Seems to be at the corner of the timing chain cover.
 
The rear corner of my oil pan on the '71 Charger is leaking too. the flange of the pan is messed up from having a wrench jamed between the pan and transmission when installing the converter bolts. I ordered a new Milodon oil pan and the one-piece windage tray/gasket from Jegs. I'll see how it seals up when I get it.
I did use the one piece windage tray / pan gasket on the 440 in the '69 Coronet using the Mopar Hemi replacement oil pan and it sealed great, no leaks at all.
 
I've read that some silicone the tray to the block and use a gasket between the tray and the pan. Just another thought.

The pan is straight as an arrow. I ordered the one piece unit thinking well if I should have to pull it in the future. It is a 7 quart pan. Now I'm wondering do I really need a windage tray? I don't do anything that really justifies it.
 
Thanks Mike, but it's all in one piece. My thinking is if there is oil puddling in the back on top of the tray maybe it would seal that. I guess if I had to pull the pan in the future I'd just have to trash it and buy another one. Do I really need a windage tray?

Windage trays are a proven horsepower gain at higher RPM. If you do not rev past 5,000 it probably isn't doing you any good. Or harm. Your choice.

I would not use silicone except a dab on the corners
anaerobic gasket maker or something else made for gaskets
silicone squeezing into your pan/ oil system is a real bitch

Absolutely. I've used Indian head since 1972 & never had an oil pan leak on any job I ever did.
