Default Rear Main Seal

Anybody know where I could get a rear main seal for a '64 1F? I'm not entirely convinced that this is the cause a my leak at the rear of my engine but I'd like to have the replacement seal available if it is.

Coolcruisers.com advertises both an aftermarket one and a Toyota one. If that year turns out to use the same as a 2F, I have a spare.

I would go OEM.

OEM Rear Engine Seal '58 to 8/'87 - TOYOTA -around $50

I have an OEM and one from Kurt at cruiseroutfitters and I can't see any difference, except the price, $16 versus $46. All markings and the item look identical.

Yep, but buying OEM and paying the higher price makes it better

Amazingly, I never buy OEM gaskets or seals and yet I never have any issues with leaks. Just buy good after market stuff like Feld-Pro and it works fine.

Thanks fellas. Is this correct: '58 to 8/'87? If so, that will make things much easier to find.

Sadly, Toyota has ditched Koyo on some bearings, so when I discovered that Toyota wheel bearings for the front axle of my 1/80 FJ40 were stamped 'Federal Mogul', I bought them at a local bearing house for 2/3rds the price. I still buy Toyota oil seals for critical applications

Just because they look the same does not mean that they are the same.Many things need to be factored besides just looks. The material used to mould them may not be the same. Each material could be effected by heat and friction differently. Maybe the radial spring on the inside has a different tension.

In some situations, aftermarket parts are just as good as OEM. But for seals, I would stay OEM. Is it really a job you want to be doing twice?

I guess it's just a matter of personal choice. If you think oem is better and you don't care about price, then buy oem.

I can tell you from personal experience, working as a professional mechanic, I never used oem parts unless that was the only place to get them. I can also say I never had to do a rear main seal (or any other for that matter) over again because of a bad seal. As long as you use a good quality (not checker el cheapo) name brand part, it meets or exceeds oem specs. A lot of these same companies actually build parts for the oem manufacturers.
