Dorman Oil Pan

grasscutter · 2025-08-06T02:40:35-0400

Today the car slipped off the jack and destroyed my oil pan.

I'd need a flat gasket for the Dorman oil pan. Flat gaskets are not available anywhere!

All gaskets are silicone made to fit the recess of the factory pan!

This time I don't feel like crawling around in salvage yard to pull a factory pan, but I might have to.

Please see pictures below.

Bead of Hondabond/Permatex/Loctite (Insert your favorite anaerobic sealant here) would work just fine I would think. There's millions of Honda's running around from the factory like that.

I'm wondering why Dorman changed the gasket surface knowing full well that none of the gaskets available would work.

This is a factory type gasket here. It's made to sink down into the grand canyons of the original GM oil pan.

because their pan is made to use RTV

What vehicle/engine does your pan fit?

This is the kind of part (oil pan) that I would probably go to ebay to find.

I recently ordered an aftermarket engine oil pan for a Toyota (although they're already a fan of their FIPG) and had to go to ebay for an OEM used transmission pan.

The engine oil pan was sold as Ackoja thru RA and came as a Vaico -- apparently they're affiliated.

But regardless, I was impressed by the selection of used parts on ebay. My used transmission pan arrived in good shape. It looks like OP may be dealing with alloy, but best practice IME is avoid used parts from rust states.

Don't sweat it -- sometimes you slip off the jack, sometimes you run over dead bodies......as Forrest Gump said once edited for TV or BITOG: "**it happens"

Yeah same was true for my old Accord. I am fond of either Honda Ultra Flange II or Permatex The Right Stuff. I’ve never seen either one leak.

How was the pickup tube and pump. Did that get pushed in enough to damage anything?

Yep, that Dorman pan is made for RTV, or it would have come with a gasket. You're better off with OEM pan and gasket. Guarantee no leaks..... I've seen plenty of leaks with factory Hondabond, or something else... Those robots are always missing spots ( clogged nozzle, air in the line, etc ) I have a leak in my K24 Honda somewhere in the MIDDLE of the sandwich style engine. Small little leak. Robot missed a spot during assembly. I've been using E-Bay scrapyard stuff for years. Just got an 03' 2AZ-FE beauty cover from an E-Bay scrapyard... $60 bucks. Free shipping. Looks brand new. ( I stepped on the old one..CRACK...DUH ) I've gotten OEM alternators, starters ( they even show you the mileage on the dash, the lower the mileage, the higher the price. Scrapyards have become very savvy nowadays. Not like the old days when they had no clue of the mileage and stuff. Hey, they gotta stay in business too !! They found a home...E-Bay

No I would not use Hondabond. It’s supposedly okay but the Ultra Flange II is far superior IMO.

Toyota FPG is another alternative.

I agree. Honda bond is junk, but it's used all over the Honda's. That just gives you more insight into the Honda brand itself.

If this were my car, I would want the OEM pan with the gasket. That said, if I had to, I would get the sealant and use that. If the car were a Honda, would use Hondabond.

If properly installed, the sealant should serve you well for many miles. The think is, you need to have the right touch to put the stuff on. Most of us amateurs, myself included, use too much, and might cause gloppiness here and there. The amount to use is pretty small, but if you use too little, you are in a different place. You also need to give the time for the stuff to set after the pan has been replaced... at least a few hours. And your mating surfaces need to be squeaky clean. You also should be torquing down the bolts in a graduated process using the correct sequence. You can watch TE videos on Youtube for superb technique... again, would want the OE pan and a new gasket.

On the other hand I find improper application to be the greatest issue. Same can apply to a gasket as well, I’ve seen blown out gaskets from gorilla tightening or uneven tightening leading to leaks. I saw one oil pan gasket where the guy had cranked the bolts down so much the little torque-stop bumps on the pan were completely flattened.

The thing I like best about Ultra Flange II and The Right Stuff is that there is very little wait time for return to service.

What is up with the shallow grooves in the Dorman pan? Am I supposed to put a tiny bead of sealant into those grooves?
