Refinishing Timing Chain Covers
I would like to refinish my leaky timing chain covers as they are fairly pitted and flaky. What is the right way to do this? Have folks had these media blasted and powder coated on the inside? Can I just sand them and bake with engine epoxy? Any advice would be greatly appreciated. Thanks

You can try epoxy I have found Por15 has a some nice products that are self leveling and make a good coating and bond to the surface.

I just re-blasted my valve covers to PC them again (had some coating failures on the outside surfaces; my fault for not keeping them clean in the winter) and the PC on the inside was in perfect condition after 3 years and 25k miles.
I'm convinced.

Oakite makes some paraffin based rust inhibiting oils that leaves a protective film if you can't coat them and need to store them for several months. You should also wrap them in some form of barrier paper or way to keep moisture away.

I'll confess that on the VC seals I always use a smear of Hylomar, but leakage from under there hasn't been an issue. Wish I could say the same for the rest of the motor
ETA: I'm doing all the blasting and powdercoating this week/next week- shoot me a PM if you want to stop by and check it out. I'm doing calipers too, but the support surfaces for the springplates are so pitted that I think I'll need to level them with JB Weld before I can coat. This can't be an uncommon issue, so my plan is to put up a separate thread. I'm expecting people to be horrified, tbh.

The inside is protected by oil, nothing else is necessary and it certainly doesn't need to look pretty. The biggest issue is if the coating comes away and finds itself blocking oil ways. It can never happen? Even when a mech is working on the car, it cant get chipped? Why take the risk?

Why? Done properly the PC is far smoother than the mag.

I still recommend the POR 15 products especially the caliper paint. It is easy to work with self leveling and as durable as PC. Makes a ceramic coating. A pint will cover a ton or pieces. i did the rotor hubs and calipers on my sons Audi and used about 3/8" off the top of a pint and they look great and have held up perfectly. They look nearly identical to the factory big black finish.
Interesting way to support your engine?

Cobalt (Anthony),
Can you share the POR 15 products and process you use? I am trying to decide what to do with my Cam chain housing covers well as the Cam chain housing itself.
