Oil pan gasket?

jmblake · February 27, 2018, 06:19:50 PM

My series 50 seems to be seeping oil around the oil pan gasket, Has any one changed one of these? Do I need to change the rubber bushings on the bolts? I didn't try tightening them, is that a option? Someone told me that the bushings hold the pan tight and do get weak and then leak

Thanks Jason

Yep change the gasket and the isolators assemblies ,they are a little pricey. I don't think you can buy just the isolators from DD they come with the bolt,spacer and isolator as a assembly. You could check with the after market people for isolators only

Thanks Cliff, I'll call and see how much they are, I need to change oil so I figured that would be a good time to fix it. Do they get torqued?

Will be needing to deal with the same issue after we return north, so please post your progress regarding this fix.

Thanks

I just called my local DD dealer (Penn Detroit) and the gasket is $37.98 and the isolators are $5.43 each, must not get the bolt with them. Not to bad so i have them ordered.

That is not bad a few years ago the gasket was a 100 bucks and the isolator assemblies were 20 bucks each

I would try tightening them first. This may just solve your problem. These gaskets can also be re-used if you clean them up. New is always better of course.

Those have spacers or bottoming bolts you can only tighten the bolts to a certain point,I had to do my 12.7 series 60 last year with a new gasket and isolators to stop a drip lol the gasket grows when you try and clean one

Does the gasket fit in a groove or is it just a flat gasket?

Fits in a grove with little tits on it to hold it in place on the newer pans ? is your pan plastic

I think it's some kind of Plastic or fiberglass by the sound of it when I tap on the side of it.

Check it close for cracks

Dang leaky 50 series.... Might as well have the two cycle. At least they don't sound like a bucket of bolts.😊 Make sure to use a torque wrench when tightening bolts.

I believe the pan on my early Series 50 is cast aluminum.

Just confirmed tonight that I do have a cast aluminium pan. Anybody know the torque specs for the pan bolts?
