Should I use Moroso or try something else for my oil pan gasket?

Advice Needed
1

I need some advice from those who have replaced an oil pan and gasket. I was considering the Moroso gasket, but I found other options like Speedmaster or PowerWorks on Amazon for around $65. Has anyone used these or should I stick with Moroso?

Any other suggestions for good alternatives?

I usually go with TA31 silicon for these jobs. I also pull the engine and flip it upside down to make things easier. The Moroso gasket has had mixed reviews, and I’ve never heard of anyone using a different one.

Are you sure it’s the oil pan leaking? This engine can leak from the top, making it look like the pan or filter is the issue.

Yeah, I checked it. Everything’s dry up top, and I can see the leak coming from the pan itself.

Silicone works best. Gaskets, even the Moroso one, can be hit or miss.

Moroso can be a gamble with the engine in. Some get it to seal, others end up with worse leaks. The best way to seal it is to pull the engine, flip it, and use gasket sealant.

I know Moroso doesn’t work well with Toyotas because of the thickness difference. I’m buying an '02 and might try the same fix for its leak. Let me know if you update with results!

I’ll update you, for sure.

Use Motorcraft silicone. Clean the mating surfaces really well, and good luck!

So you’d skip the Moroso gasket and just use the silicone?

Yes, definitely.

@Riley
Can I do that without pulling the engine, or is that impossible?

I have a '99 4x4. The cross member is the issue. You could try, but it’s going to be tight. There isn’t much space between the block and the pan.

Right, so I’d probably have to jack up the engine to get more clearance.

Could I just apply the TA-31 silicone to the pan and install it from underneath the truck after draining and cleaning it?

Most people say doing this with the engine in place won’t work. The surfaces are hard to clean properly without flipping the engine. Also, the RTV bead profiles need to be just right, and the pan needs to go on quickly after applying the silicone. I tried doing it the redneck way with a friend, and while it was a pain, we got lucky, and it stopped leaking. But honestly, if you’re going that far, just pull the engine and do it right.

Do it right. Use TA-31 silicone. It’s also a good time to reseal other parts and inspect everything while you’re at it.
