Hey there,

Wondering if any of you shampoo your engine? Many M3 guys to it but not sure if there are design differences that make it dangerous on 911's?. On the M's, we just make sure to cover up the alternator and don't have a forceful spray.

 

I would like to know the same thing. On my old M6 i used scrubbing bubbles and it was amazing. Sound silly but it works wonders and is super simple to use.

 

Not sure but I would make sure 100000% that the engine bay is cool before doing this. Those turbos and piping wont like cold water sprayed all over them when hot.

 

Is there some good reason to do this? I've never done it, never wanted to. The engine bay is just sacred space to me, so I am not about to shoot water and chemicals in there. I guess if you're driving in salted roads and grimy stuff it may make more sense.

I'd reach out to some of the high end details guys who frequent this board.

Good luck.

 

m3 guys do it because the engine bay is actually worth looking at, looking at a 911 bay is like lifting barbies skirt

 

Haha. So true! I must admit, the M3 engine bay is sexy. I can't believe how many CF parts you can buy to show it off.

 

Would not....feel like there are more things that can possible be tinkered. P motors are somewhat hidden wheres the M's are right there for ya to clean and dry off properly. I would want to be using air gun to spray every inch of my turbo down and possible pop something minute off (happened to me before, hence the hesitation).

do what I can but absolutely do not go nuts with the engine on this car.

 

Apparently the porsche designers don't think it's sacred. For anyone who washes their own car you know how wet the engine gets after a wash. I always place a towel over the engine and close the lid over it before I wash it and I still end up with water on the belt, alternator.0, air box, etc. Stupid design. OP, you may not need to wash the engine. It gets a good soaking everytime it gets washed!

 

the water drains off the back glass into a metal gulley (in engine compartment) with side walls too short and water just pours off this drought onto engine.
Open your engine lid and pour water onto the back glass and you will see for yourself.
I put some rubber weather stripping along the bottom of the glass which stopped the damn problem. The sides of the drain gulley across the engine compartment have been extended to hold more flowing rain water in newer models.
The same concept is with any rear trunk, but with trunks, there is rubber seals to stop flow of water into trunk. I guess with engine heat, Porsche has left off the rubber stripping. Seems like a bad design to me for draining rain water of the back glass.
