Valve cover replacement
Looking to replace my stock valve color on the lnf with a powder coated valve cover. Just wondering what the torque specs are on the bolts and if I need any other info on doing it, was unable to locate any of this info on the forums!
Thanks

I didn't. I made sure it was hand prepped prior to coating. There are filters on the back side of the valve cover to catch oil condensation. You will NEVER, EVER get the sand out. It will come out in chunks when oily. There are many ruined Evo and Miata engines for the very same reason.
Here's mine, properly done:

I got mine from modern performance all ready powder coated. So should I be fine then ? And I ended up just breaking the one line off of the turbo.

Just need a blaster that's dedicated to it. Discussed it with my PC, and we decided to hand prep. I still washed the hell out of it when I got it home though.

Well i called modern performance and they said that they said yes they do sand blast their covers. I also emailed gloria@powellracing- they said yes they sand blast also. so should i send the modern performance valve cover back and just do it myself ???

I am careful to say "media blast" but the current common nomenclature is "sand blasting". Its not sand. In this case.One issue we have, I tried a series of rockers with an acid wash and no media blast and the pc came off and I had to warranty a bunch of the covers. It was frugly.
They need to be scuffed at least before or after washing etc.
But Wangspeed is 100% correct, the Evo guys got into huge problems with engine issues. I have been doing the exchange program for 3 years now and only comebacks were the aforementioned non media blasted covers.
Oh and candy colors not being consistent. Candy is not consistent, the cover is not consistent and the way we dealt with that is , however, easy.
NO candy colors anymore.
Textured finishes are best for rocker covers no doubt, Warren leads the way.
check out this powdercoated textured black M62...
