how to tell if your engine is stock or not
 

I bought my fd with around 150k on it the compression when I bought it was good it always starts up quickly hot cold don't matter,the car was bone stock when I bought it. The history is it was sold in Hawaii then shiped to los altos Cali, frome what I see one owner and has been in and out of shop for emissions 15 times then sold at auction to the dealer I bought it frome. I have noticed plenty of goop under motor mount bolts and the eye hook near the passenger side firewall is bent toward the front of the motor slightly. is this a sign of a rebuild is there any other way to tell, It runs to good (knock on wood) to have so many miles on it.

Do a compression Test and go from there.... if you say its running good.. and all.. get a compression test and find out how healthy the motor is!!! and all that stuff u mentioned about bein bent here and there dont mean anything could jst be sloppy work!!...

did one when I bought it it was good the eye hook is there to attach a chain to a cherry picker to pull the motor out the only way it could bend is from the engine hanging frome it like pulling the motor.

then...... there's ur answer... if all that check... pretty sure its good then!!..

any other input or thoughts would be appericated
