Permatex oil pan gasket

Guys, I bought an oil pan gasket from the fleabay, but it's not the right one. One of the bolt holes doesn't have gasket around it. I am wondering, is it advisable to use blue RTV for a gasket?

This is what I have (disregard the tensioner gasket):

This is what I need. Notice the bolt hole with gasket around it - circled in green.

I think I would see what bike the unusable one actually goes to and sell it. Get a correct gasket is my opinions.
 
As far as RTV, Just Say No. It doesn't belong anywhere near your motorcycle.


The gasket on the fiche for the 1982 GS850GL looks like your first photo.

Less than $9, too.

The exact same gasket is used on all GS750, GS850, GS1000, and GS1100 8-valve engines. Paste in the part number here: 11489-45001-H17

So if you're working on something else, let us know what it is...


Anyway, it looks like 11489-45001 is the original gasket part number, and it has the extra hole like that photo of the red gasket. It's been superceded by 11489-45001-H17, which has a larger hole. In other words, all that extra material isn't needed. There aren't any passages in that area.

In other words, use the black gasket you received. It's fine; it's just an updated gasket.

And DON'T use any RTV. Install dry onto very clean surfaces, or smear on a very thin coating of grease if you like, and the gasket will peel off easily later on (and will most likely be re-usable) should the occasion arise.

Right in principle - but I'd point out that a lot of modern motors are going away from gaskets as such and using sealants instead.
Threebond is the sealant of choice - but where no oilway crosses the gasket surface, I'd be happy enough using even RTV.

I recently had a latish CBR600 Honda roadrace sidecar engine here which to my surprise only used one gasket - the head joint.
I imagined that it was a PO who'd deleted them - but a look at the parts fische told me they were never there.
 
Gasket replacement RTV products are tough and the ooze out bead doesn't break off easily. These products have been in use going back almost 30 years at this point so it's nothing new. My first experience with them was rebuilding a 1981 Mazda Rotary engine where the oil pan and front cover were both sealed with RTV. I remember struggling with getting all the old RTV off so new could be applied during assembly.
 
Well, I don't know where the discrepancy is, I picked up a gasket from a local shop and it matches the pan cover. The gasket that matches the one in the original photo was installed and instant oil leak, this is what started me on possibly using rtv. The bike is a 1982 gs850gl, just like what's in my signature. This isn't the first time a part has been wrong. I ordered the drain tube for the airbox and the part that was shipped had the correct part number, but isn't the same as the original part.

The issue with the "updated gasket" is the bolt in that corner of the cover goes through the bolt hole further away from the edge, the one that was circled.

Get an OEM oil pan gaskets, it has to be the right thickness to seal. And NO to Permatex RTV
 
Hmmm, very strange. Glad you found a gasket, but I can't explain the discrepancy. I've been in several GS850 engines and never noticed anything like that.
