Hey guys/gals my brand new 2008 MCS with less than 1500 miles, has begun to slightly rust around the turbo housing.... I want to know if it would be ok to spray that area with a little wd-40 to prevent any further rusting i am a little OBC !!!

Will this have any negatve effects on my engine or the turbo???

Thanks NAM!!!!

 

Turbos get HOT! I think the wd will just burn off.

 

Do not spray WD-40 on your turbo, or any other oil based substance...........

If this is really going to bother you, you can remove it and paint it with BBQ paint or exhaust header paint..............

 

The turbo is just raw iron. It will rust, period. Don't spray any WD40 or anything else on it. That stuff is very flammable.

 

Don't spray the turbo.

I knew guys in the Army that swore on all they held holy that WD-40 would destroy an M-16. They said it changed the tempering of the metal and caused all kinds of mayhem.
Only people I ever heard say something bad about the "can of fix-it-all".

But it aint for turbo housings.

 

ok i got it.... kool thanks. No wd-40 for the turbo do you guys see rust near turbo heat shield too?

 

That's a good idea, bet it would look good painted flat black...

 

Agree on using HiTemp Paint.

On Aircraft Turbochargers, we use a 'special' penetrating oil called "Mouse Milk" annually on Waste Gates to prevent sticking.

We got it from RAM Aircraft, Waco, TX, but Google for a source.

Useless information (post ) of the day:

"WD-40 is the trademark name of a widely-used penetrating oil (and cleaner, lubricant, and anti-corrosion) spray solution commonly sold in hardware stores and other such retail outlets. Developed in 1953 by Norm Larsen, then working for the Rocket Chemical Company, it was originally designed to repel water and prevent corrosion,[1] and later was found to have numerous household uses.

WD-40 stands for Water Displacement, 40th formula. Larsen was attempting to concoct a formula to prevent corrosion, by displacing the standing water that promotes it. In the process, he arrived at a successful formula on his 40th attempt.[1]

WD-40 was first used by Convair to protect the outer skin of the Atlas missile from rust and corrosion.[1] The product first became commercially available on store shelves in San Diego in 1958.[1]"

Nothing useless about that post, I find it interesting.

 

i second that!!!

 

Are you saying that the heat shield on the Turbo is rusting?
It seems to be crappy tin, so don't worry too much. It keeps the heat in.

 

spray it on if u want....its just gonna smoke like hell as it burns off. Did that on my Wolfsburg 1.8T and watched it happen because I thought the same thing. Just take it off, use a wire brush to break up the rust and spray with hi-temp anti corrosion paint. Thats it.

 

Yikes! just let the turbo rust. It's rusting because even high-temp paint won't hold up on a turbo.

 

Couldn't you take it to the dealer for replacement near the end of your warranty? Don't MINIs have a 12 year rust warranty? I'm just saying.. I don't know exactly what it covers, but I thought it was Bumper-to-Bumper.

 

haven't really had any issues with my jetta. are you gonna track your mini? that might be the determining factor on the paint. My Wolfie is a daily driver w/ extras just for fun, used some VHT....worked for me. Just clean it really well and mask it off for overspray

people use hi-temp paint on heads, headers, exhaust manifolds...etc....on hot-rods....if it can hold up on those parts, i think a turbo on a mini should be fine

 

 

you're nuts if you think any paint will last on a turbo more than a few months if anybody is that worried, get it thermal coated. that's the only sure way to make it not rust.

masking it off and spraying it on the car ensures the paint WILL fail as rust will creep up from where you didn't paint. The best way to do it is to remove the hot side:





That was black thermal paint with silicone meant for sealing header wraps etc. I have it on my exhaust tips and it lasts just fine. On that turbo, six months later, it was rusty again.

 

how bout this....its not really an arguement if both sides are coming to a similar conclusion from different vantage points....the man asked if a cheap fix would help a minor cosmetic problem. A can of hi-temp paint would cost him maybe $7.99 depending on where he buys it. I said "take it off and spray it" not "spray it while its still attached." I sprayed some on my Jetta 1.8T(daily driver, not a track car) and it lasted a lil over a year. I asked if he tracks his car cuz it would definitely be a factor in how long it lasts. Worst case scenario: a year from now, take it off, clean it and spray it again....probably using the same can of paint he bought a year ago. It won't hurt anything and he will be happy.......whats the problem with that exactly?

 

did you really have to make the 'T' red for us?

 

nice comeback
