I was thinking of purchasing my first FD, but if there is no paperwork to show that the motor was rebuilt, is there anything i can check that would indicate this? Sorry if this is a shot in the dark, but any help would be greatly appreciated.

 

Not really....how many miles?

Get a compression check...that will at least let you know if it needs a rebuild.

 

Look at the color of the silicone around the oil pan, between the irons, and around the front -eshaft bolt. Original motors had grayish silicone (tends to yellow) while remans have a pale orange silicone. If it was rebuilt by some independent shop then all bets are off.

 

also look for any strange paint marks or number stamps on the rotor housings.

i believe mazda remans have a blue badge stuck to the front cover.

 

it'll be clean?

 

Don't worry about that. Just get a compression test done. The motor being rebuilt doesn't mean that it's good. A compression test will tell you the health of the motor.
