149 oil pan gasket

[Mr Bob]

I know this post should be in the Kohler engine section but I felt it would be seen a lot more in this section. That being said, on to the question. For those of You that use a sealant on your oil pan gasket, what do you use? My oil pan leaked on the engine I rebuilt. It is now sitting on my garage floor with the oil pan off and cleaned. Would like to get the engine back in the frame today if possible. Thanks in advance for your help. Have a great day.

Hello! First I am assuming you used a gasket. I would use a little black RTV to stick gasket to pan. I use nothing from gasket to engine usually but it wont hurt too use some black rtv there as well.

The key is to put gasket on pan and let it tack up just a little. Then do the dame with pan to engine. Dont over torque the bolts. Just snug them up. Let everything dry then snug up just a little more.

Thanks for your info Cooperino. How long do you let it tack up? I used some black sealant just between the pan and gasket. It was not rtv. Going out now to buy some. Don't want another leak. Thanks, and have a great day.

Not long.. 5 min maybe. Just long enough to make it so gasket doesn't slip and slide around on ya.

BTW. Use a thin layer NOT a bead of rtv.

Permatex with the brush applicator.
Never RTV.
Check your pan carefully for cracks in the corners before installing, especially if it's a cast iron pan.

Recently disassembled and re-built a 341 that had been put together with the RTV crap
It was slobbered everywhere inside and outside the engine.

Um.. Whats wrong with RTV ?? Permatex makes RTV?? not sure I understand the comment
Permitex is a name brand not a product.. they make 100's of products

I'm a fan of Permatex high tack spray-a-gasket a light coating on both the pan and the gasket, let it sit for about 2 minutes till tacky, lay the gasket in place, and assemble.

That's good stuff as well.

If you have an aluminum pan, make sure some well meaning person didn't put too long a bolt in the pan-to-frame holes, as it will crack the blind holes into the oil sump resulting in a slow leak/weep.
