Wouldn't it also require a review of all the fasteners for metallurgy, appropriate torque spec, etc.? |

Question for the experts. I've been tinkering with trying to refinish some used valve covers, just to see if I could get them in shape to replace mine on my car. I had them blasted and powder coated, probably not the best job, but really only care about the safety of using them. I do not believe they are warped, but I'll get that checked. I had to find random shops to help me with these, something to do over the lockdown period, so I didn't expect cosmetic perfection on everything, but I do want functionality to be almost certain.
My main concern is the inside, some parts appear to have ridges and such that I'll post in pictures, they don't appear to be flaking, and I can scratch them with nothing coming off, despite how they look.. I'm not sure if this is just how magnesium acts, and it's not perfectly smooth, or if it's something that is not supposed to be there. The other thing I want to make sure, is how perfect do the edges have to be to make a proper seal with the new OEM gasket? And no, I do not prefer to pay $1400 for new OEM, so I'm hoping to make these work if possible. |

Those look like casting flaws. I’d be looking more at the perimeter that the gasket contacts.

That's what I was hoping, but I couldn't think of the word/cause of those places on the inside, thank you! I just wanted to make sure those weren't serious in terms of anything structurally being wrong, where the heat would cause damage or something. How perfect do the edges need to be? this is probably the worst looking edge/corner..

Curious to hear what the experts think, too. My covers are leaking now also. I've replaced gaskets in the past so I'm toying with the idea of a full OEM replacement. I'd hate to try and refinish them only to find out they were warped and spending $$ on refinishing didn't solve any of the issues. Although I love the way the red looks! |

Bead blasting used magnesium castings will always expose porosity. Even if you coat the sealing groove you'll still need to augment the seal with a silicone gasket maker like Dirko grey. |

I doubt anyone would cough up the money to do it, even if it was done, its going to be a one-off project.

If it's been discussed before, forgive me for missing it -
But I just came across these Future Classics powder coated valve covers in IND's site. Seems like a competitive price. Am I missing something? Anyone have experience with these? https://ind-distribution.com/collect...alve-cover-set |

If Im not mistaken, these are used valve covers, powder coated with the hardware from IND. Mporium has several sets at their shop for around $750. If Im off Im sure someone will chime in. |

Just remember OEM does not come with all the hardware. Its best to find a nice used set and have them done on your own. Then you dont have to have your car down so long waiting on a powder coat guy to get them back to you. Ive seen Mporium's and they are in quite nice shape with different colors to choose from. They come with the hardware for that price. That might be the way I go here in the not to long future.

Unfortunately, now, they are just bare and you have to supply all your own hardware and gaskets. I don't think it's a good value at all. |

Anyone tried polishing them? A plus would be no future flaking or peeling.

Yeah, you picked up the valve covers I had replied first to the ad for but was out of town to respond. You got a great deal on them for sure! Super jealous, they came out super nice! |
