Engine splash shield - drainage?
Hi Everyone,
I seem to get water...in my engine splash shield...afer it rains or after I wash my car. If you open the hood and look down, you can see the water just lying in there on the shield.. Is this normal? Is their a drain for that shield? When I move my car...I can see a trail of water. At least I think it's water. If there is a drain hole...maybe mine is blocked. If there is not a drain hole...will adding one cause a whistle sound when I drive a hign speed? I would aooreciate any comments or recommendations. Thanks Ben |

There is no drain hole... just gravity and speed...:D Drilling a small hole at the low spot should not cause any issues or whistle if you want a drain...

Personally, I have had mine off for at least a year, it is a DD and I had no issues all winter with no shield. Got tired of taking it off for oil changes and it allows more cool air to get into the engine bay.....

The Aero hasnt had a splash shield for about a year also...the SSB does, but only because I havent been under it to do anything....:)

I leave mine in place, but only because I'm once of those evil kids that likes to hit 135 every now and then.
I'm certain it serves a purpose at that speed. FWIW, Steve (32krazy) left his off and went for a speed run of 140+... he felt (and heard) a huge difference in wind. So, mine stays on. |

Re: Engine splash shield - drainage?
Some people's theory for the reason for the purpose of the engine splash shield is because MB didn't want their cars dripping oil on the driveway/garage. Drill a hole in it if you want. Otherwise, it's OK as is.

I would be surprised if it had any aerodynamic value to it. I think the main reason for it is that the typical Mercedes owner would take offense to having any potential oil stain their garage floor. ;)

Re: Engine splash shield - drainage?
I drilled a small hole in mine to drain....have had no whistling from it.
Mine stays on because my engine compartment stays noticeably cleaner than my other vehicles without the shield. Here in FL, sand accumulates on everything under the hood....not so much in the XFire. |

Don't worry Bob I will beat both of you :D

It may be different in Steve's SLK, but ask Ole Doc about his, he has seen some pretty high speed, and with some regulalarity, has had his off for a long time as well. I am in traffic a lot more than I am going 135 (and I do hit it now and again) so the known cooling effects far outweigh the aerodynamic gains, if there truly are any. Car Aerodynamics 101 |
Re: Engine splash shield - drainage?
Effective or not, I know that I am now realizing 28-29 MPG (since I've added the intake and exhaust mods).
While I'm sure the engine mods do help, the aero of this car is helping out as well. How much does it affect the overall coefficient? Not sure, I'm no aeronautical engineer. But I just know Steve could tell a huge difference on his as the needle climbed. He not only felt the difference, but heard it as well. And if you can "hear" the air catching on something, it means that area could be smoother (think bad weather-stripping). Any sport-touring coupe that gets ~30mpg is a freaking winner in my book. That's only 4mpg away from a Focus, and we're a lot faster and better looking. :D |
Re: Engine splash shield - drainage?
I have a headache just thinking about it do or don't , yes or no, on or off, :confused: :p
