Oil Pan Gasket

Post by alexob53 » Sat Oct 15, 2016 1:52 am

Hello XR lovers,

I am confused about the two different styles of oil pan gaskets. I ordered a front crank seal for my 88 XR which came with a partial oil pan gasket, 1 piece of silicon semi-circle and 2 small cork pieces. From my understanding, this is for an early 85-87 XR. The later XR (I think) came with a 1-piece silicon gasket rather than a multi-piece thing. My question is, did the block/pan actually change or just the style gasket used, and can I install a multi-piece early pan gasket on my late XR? Thank you all!

BTW, I will be making a thread on the changing of gaskets/seals, doing water pump, thermostat, thermostat housing gasket, valve cover gasket, front main seal, cam seal, aux shaft seal, timing cover gasket, rear main seal, T9 gaskets and seals, turbocharger gaskets, probably some hoses, and anything else I deem necessary after digging in.

The front seal and the rear main bearing cap are different. The early ones have a groove for the multi piece gasket setup, The later caps are flat and require the one piece gasket. People have filled the early grooved caps with epoxy and machined it flat. The one piece gasket which is all silicone is a better design and leaks less.
As far as your write up project, you will need to find a front main seal installation tool and the shop manual has very specific directions for everything you are doing. Here's a link to a motor build I did which shows some of the stuff you will be dealing with.

Thanks very much, I will order the right gasket and buy the $20 cover alignment tool equivalent for the seal from MC2. I have also ordered a couple tubes of RTV sealant since I'm doing water pump/thermostat and will apply it as I see necessary. Thanks for the info!
