Oil pan/windage tray gasket--best bet for no leaks these days?

[Mfr426]

Hey folks, it's been a LONG time since I posted. In the last year I had another daughter, a large home addition, a stroker 70% done and my nuts snipped  . So, no more kids (2 great daughters now) but money is a bit better right now and I think I can finish my stroker. Thanks to Ron for all the help with so many questions in the past! He's been invaluable. Here's just one more question that I've been thinking about for some time now as I'm accumulating the final parts.

I am going with a new Mancini branded hemi pan and a stroker windage tray on my 440>512 motor. On my old 383 motor I also had the windage tray and a new pan and I had a heck of a time with oil seepage. It was not THAT bad but I HATE LEAKS period!!! I dont want the same thing with this 440 stroker motor that I'm doing.

So, any suggestions on gaskets? Are FelPro still the ticket for oil pan gaskets? The windage tray really adds another "layer" of difficultly here. Did Mopar ever come out with a good design like they did with the trans pan gasket? I ran advanced searches on the site here and could not find a post on the suggested gaskets for an oil pan.

Any help would be great. Happy New Year to all and if things go as planned I'll have the new monster motor installed for Carlisle this year!

  I believe Moroso sells a nice one for your app.  It's almost like a foam/squishy/steel lined gasket. I installed it on my 440 and fits real nice.  Hopefully when my engine is done this year, I'll give you more info.

Mike, i've had good luck using the felpro gaskets with Ultra Copper Permatex on all surfaces. The key is to just skim coat it and snug it down for a day or two to allow the sealent to set up. Later torque the bolts down but don't overtighten. 

Overtightening with too much silicone will always cause sealing issues....the silicone gets pushed out the sides if it's not allowed to set up so patience is the key. 

Congrats on the little ones....i'm sure they're keeping you on your toes !

Thanks Ron (and J-440), that's what I was looking for. I'll add the Permatex to my list.
