Big nose crank seal
"Big nose" 1991-05 front crankshaft oil seal
Recommended with every timing belt change.

Made in the USA

Availability: On backorder
You can place an order now and we'll reserve it for you. We are expecting the parts around January 2020.



Front crank seal fits all Miatas after mid '91 with long nose (big nose) crank. While this isn't always leaking when you do a timing belt change, it will be leaking before your next change! They don't cause a catastrophic failure, but they make a real mess of the bottom of the engine. Included in our 1991-2005 timing belt kit.

Fits 1991 models with VIN of 209446 or higher, and all 1992-05 models.
