Title: Safest way to expose engine stamp
Post by: CL8N on October 06, 2024, 11:56:53 AM
I'm trying to verify whether my engine is the original or not, but having a hard time making out the engine stamp. What's the safest way to clean this up and try and get a better reading?

I had an appraiser tell me back in 2009 that it had the original motor and transmission, but I'm just trying to confirm some of this myself as I'm considering selling the car.

I have no clue. My knowledge of this car is very limited.

The motor has been "built" from what my brother told me. So maybe this is the boring job that was completed?

".006"
Most likely the Decks were machined 0.006" clean up would be my guess.

I would use a Paint remover (DOT 3 brake fluid or commercial paint remover)  and a plastic bristle brush to remove the paint from the pad, just be careful to min mess and resist the temptation to use any scraper, blades, power wire wheels etc. Be gentle and take your time, No sandpaper, No scrapers, No razor blades. It can be done.

I think you're right. Thanks for taking the time to reply!

Lacquer thinner on a rag is the best way to clean the pad. 

Then maybe use some 000 steel wool.

Gum cutter, carb cleaner, brake clean and a Scotch Brite pad was typically my best bet. No sharp metal objects.

Gum cutter isn't a bad idea. Thanks
