Mancini Racing has them. I cut in the extra slots. It comes with 3 drain slots.

I haven't tried the new Permatex version of Hylomar yet, but I actually liked the old Permatex version of Hylomar BETTER than the actual Hylomar. I have been meaning to try the new Permatex version, but a little goes a long way and it will be a while until I run out of what I already have.

As to "The Right Stuff", that just may be the best gasket maker I have ever used. It works. Maybe too good. So be careful where you use it. You need a stick of dynamite to blow the pieces back apart. It sticks that good. I have ruined parts before trying to get them apart. Because of that, about the only place I use it anymore is on the differential.

It's leaking really bad now and just dripping rearward everywhere after today's car show





15 inch pounds?
Yeah, I bet it leaks like a sieve!
What did you have it torqued to previously and did it really "feel" like 15 inch pounds was enough to load the gasket/oil pan flange/fastener? That's hardly screw driver tight!

If in doubt, calling the Toll Free number on the package and instructions you could have received personal/professional assistance and saved the grief of having to R&R everything again. Why rely on suggestions from anyone other than who knows the product best?

Out of all the oil pan designs from all the manufacturers, nothing is more simple to seal than a B/RB Mopar oil pan.

It's a 5/16-18 fastener with a fairly dense gasket and stamped steel oil pan....... give it 100-125 inch pounds oiled. The gasket can stand quite a bit more than that but your oil pan can't.

Again, when installed "properly" you Will Not be disappointed!

Debated a long time about gaskets and sealers on my Hemi build. I used 4 dabs of RTV in the intake corners, and the rear main seal corners only. Everything else was installed bone dry. No leaks. Cometic head gaskets, 440 source rear main side seals, and a crappy Fel Pro gasket kit that needed gaskets trimmed everywhere.

With Fel Pro cork pan gaskets, I did NOT torque the bolts to factory spec. I tightened them evenly until they felt snug. Since the gasket was dry, it crushed evenly and didn't squeeze out or tear.

(P.S. If I had known about Superformance-Products gaskets beforehand, would have bought from them instead.)

Roadhazard, your PM box is full, wanted to ask if you recommend any kind of sealer on your Hemi intake gaskets. Jim

Ordered a set of SuPerformance oil pan & valve cover gaskets today from Hughes. I'll be trying them out for the first time when I put a modified Milodon Street Hemi replica pan (not a flat flange, unfortunately) with a modified Milodon-style full-length windage tray and a new I-J crank scraper. That's a lot of surfaces to seal: block-to-scraper; scraper-to-tray; tray-to-pan.

The last time I assembled this engine I used some Victor cork (cork & rubber?) oil pan gaskets that have a steel core. I used either Permatex High-Temp orange or copper sealant to "glue" both oil pan gaskets to the windage tray and let those dry overnight w/ small clamps holding the gaskets in position on the windage tray. Then I installed the windage tray dry, other than putting a dab of sealer at the joints where the timing cover and the rear main seal holder meet the block's oil pan gasket surface. I don't recall having any oil pan leakage issues, so that approach worked OK.

My plan at this time (and feel free to throw in your $.02) is to seal the scraper directly to the block w/ an RTV-type product and let it set up per the scraper's instructions. Then "glue" the SuPerformance gaskets to both sides of the windage tray like I did the last time, and install the pan & windage try dry... unless the general consensus is to put at least a thin layer of sealant on the scraper-to-tray and tray-to-pan surfaces to play it safe w/ all those layers.

I still have a set of those Victor gaskets, even though I'll be using the SuPerformance stuff this time. I had also picked up a set of the Milodon "crush proof" gaskets a couple of years ago, only to find out from Mr. SuPerformance on this thread that they're not what they're advertised to be. Well, better to find out here, instead of the hard way by using them and regretting that decision.

Oh, and my next build will have yet another layer to seal because it'll incorporate a main cap girdle in between the crank scraper and the windage tray: block > scraper > girdle > windage tray > pan. Ugh...

What I have done in the past Brad, to get all those individual layers to go into place together, is to strip out some individual strands of 14 or 16 gage wire and use them through a few bolt holes to hold everything together as they go into position. Since I started using that composite tray/gasket combo, I don't need the wires. But you have more layers going on, so it could be a viable alternative to gluing stuff together.

I used to pull them out after the assembly was up and in place, but started just leaving them in place permanently. They are small enough that they didn't affect the seal.

And at the risk of sounding like a commercial, I don't assemble ANY gasket dry since discovering Hylomar. Other than a couple of bucks for it, what's the down side? Even if it's not needed, it doesn't hurt anything. Just a bit of extra insurance.

IHTH up

Just clean it off with some carb cleaner and see if that's where it's coming from.

Your leak is most likely coming from the left or right rear corners of your valley pan. It's the one spot that you typically can't see. I would check both corners. Then install a Superformanc valley pan special corner gasket. Make sure you don't mix up the left and right special corner gaskets that come with the Superformance kitπŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“πŸ€“ I would also use USAF jet fighter ultra glueπŸ‘πŸ‘πŸ‘

Brad - I hope you are using studs rather than bolts to hold that big stack of gaskets together? I'd hate to R&R that stack up from under the car. Not so bad if you have the engine flipped over on an engine stand though. Good luck!

I had a combination of studs and bolts the last time (and I don't recall why), but will look through my hardware and see if I still have the rest of the studs to make a full set.

Oh, and my new gaskets arrived today.

Hylomar saved my butt once because a cork Holley fuel bowl gasket cracked sending fuel everywhere. I coated it just to make it glossy, and it fixed the leak. Never did get it fixed, I sold the car several months later.

I cant say enough good about it. I really like how it disassembles without destroying the gaskets
