    Edelbrock Endurashine problems

     



    I have seen a lot of nice cars running around with Edelbrocks Endurashine carbs & intakes on them, the following intake was purchased in 2006 and I hope they have the kinks worked out of there product by now. The intake was about 3 years old and the finish started flaking off, I am a huge fan of Edelbrocks but don't think much of the Endurashine finish (at least not after its new) it looks great new, but its not chrome, and they don't advertise it as such. Its a clear coat with a silver layer on top a black coating, my guess its a form of silver nitrate similar to whats on a mirror, but after the clear coat starts coming off, which the silver seems to bond too the black is left.
    The car has never overheated or any chemicals been used on the intake, if anything the opposite, simple neglect, but replacing a intake due to mechanical issues is a pain but for simple cosmetic issues when you pay more for it is a real pain. The intake will be powder coated, problem is the clear coat comes off like cellophane tape when being blasted and clogs the sand blast cabinet! I have to say their sand castings are quite impressive, just wish the finish was and hope nobody else runs into this mess!

    How about if you just media blast it and leave it alone? Or media blast it, and get after it with your little polishing wheel?

    Roger, Good point! I would but its my brothers, he is not a polishing type of guy if you know what I mean (thus the reason I know there where no chemicals used on it) and after blasting its coming out a peculiar color, kind of with a gold cast to the aluminum, like maybe they chemically etched it or something before coating? I figure the powder coating would make it a little less labor on my part!

    I can't comment on powder coating a manifold, but I can say that I had the one on my T bucket aluminum ceramic coated (Jethot type) and it still looked good 6 years later. Cleanup was easy and it never stained.

    I have wondered how the Endurashine would hold up. I figured it was some kind pf paint process.

    yep i seen it fall off and i will not run any of the endura stuff thru my jet washer or power wash it as it falls off . the best thing you can do is blast it and get it powder coated i seen some of this fall after time around bolt holes .i use at the shop on new or used intakes in sliver acrylic lacquer 2 very lite coats and still looks like blasted clean aluminum .engine rebuilders sell paint well lke sSiver seal or Goodson . the gold color on the intake is a corrosive protection and many companys use it on there aluminum parts if in marine use .take some time blowing out the intake out to get what ever you blast it with sand //glass out of it it the last thing i care to do is blast clean engine parts. intake s are to bad as the on seams of sand to hang on like oil pans double or over lap seams were sand gets mix in with oil

    I'd try a little phosphoric acid on a small area to see if the aluminum color returns. If the acid does nothing, then maybe there's still something on the aluminum.

    You can buy special aluminum etching chemicals. When I worked in a plating shop, one of regular operations involved cleaning aluminum parts for M16 rifles with the stuff, to remove coolants and eat away some minor burrs. We ran out of the stuff once and tried a dip in our strong alkaline hot tank, but it left a black sooty residue on the parts.
