"Ashy Larry"...

...now that I have your attention, that might be the new name of my M.

Has anyone seen this type of residue/corrosion/"ashy'ness" on the front of their blocks? At first I thought there was a coolant leak spraying in the bay (been there done that with an E39...) but there isn't any other residue anywhere and no history of coolant problems (car only has 25k miles).

I'm beginning to think it might be salt air related. I do live near the coast but I wouldn't think after just a couple months there would be any corrosion already. Anyone else have this? Anything I can possibly cover these parts (front part of both blocks) with? I think they're a different treated metal than anything else in the engine bay. For lack of a better analogy, can I "lotion" them up with something?

Finally, should I be worried about the same corrosion on the INSIDE of these parts? Outside I can live with but if stuff is happening inside I'd be worried...

Also FYI the engine bay is incredibly well kept. I clean it EVERY time I clean the car each weekend. The car has never been run on salted roads, etc.





Looking under intake elbow to driver's side of front of the block.

Same on mine - salt environment. It should clean up fairly well though. I use Meguiar's APC...might hit up the detailing forum for more suggestions.

Definitely looks like oxidation caused by moist salty air.

Not present on mine, so its most likely caused by your environment

Yep definitely was thinking it was salt just wanted others feedback. Any thoughts on the inside of the block? Anything I should approach the dealer about?

I'll definitely check out the APC and the other forum. Thanks!

That is what I figured. I didn't remember seeing it when I first got the car. I also didn't think about it before but I just looked at pics from when I first bought the car (duh...) and no salt oxidation...

Yeah a bit odd. It must be a different type of metal or treated differently. You would think BMW would have addresses this as I'm sure a TON of vehicles out there are near the coast.

I'm probably 300 yards from water and there is a definite breeze at times.

Pics didn't come through but I'm sure it will clean up. Was just curious if I should be concerned with the inside face of the piece and if there is a protectant I can put on the outside.

Thanks!
