Hi everyone.
any comments on ONR would be appreciated. Washing the beast with soap and water in the back is resulting is some initial squealing though I don't normally drive it after a wash and it goes away right away.

all the best!

 

Im not a huge fan of ONR unless the car is just dusty...and even then.. I like a good old wash w soap and water. I find laying a nice thick bath towel over the engine then closing the hatch over it keeps 90% of the standinv water off the motor. Also I always dry the wheels, trim, mirrors, engine compartment, ect...with a battery operated leaf blower to really move all the stading water. Works great!

 

I might try the leaf blower but I am sure my wife will think I have lost it

 

do you close the hatch all the way?

 

The last time I washed mine I cut a large trash bag open placed it over the engine then shut the lid. It kept everything dry. Just dont go crazy and start it up before you remove the bag

 

The main portion of the wash-water comes in thru the bottom of the rear window glass and empties into the engine compartment. The 2009 corrected this somewhat by building a larger rimmed channel circulating around engine compartment. They cannot use weather stripping there like in a conventional trunk because of the high heat present (I guess).

If you open the engine lid and pour some water down the rear glass, this really makes a mess. With the engine-lid closed, it still pours in but not so much. I pushed a 1/2 piece of weather stripping along the entire 3 foot long slit where the bottom of the glass goes under the metal piece. Now no water in engine compartment....but I continue to cover the fan hole with a rubber mat when I wash the car.. because water comes in there too, so this means that the fan area is not channeled off correctly either, in removing incoming water away from the engine. What was puzzling was how was so much water getting to the engine with washing the car or in a bad down pour with entire engine lid covered.

It's just a crappy design that from a '09 engine photo looks somewhat corrected in 2009.

Because of this water on-engine issue, one fan belt ruined and an air mass sensor destroyed. Now that the car is out of warranty I wanted to find out where the water was coming from. And too I got tired of the fan squealing for hours after a rain or wash, plus it took some time for the power steering to burn off water and function correctly. Earlier, Porsche dealer said just a normal factory squeal, nothing can be done.

When I called Porsche about the defect, they said to compare my problem with other porsches at the dealer to see how bad mine was in comparison.....yeah right.

That piece of weather stripping is permanent now. But when the car is parked at work during a massive Fl-rain storm, I still cover the engine fan opening with a mat because water still gets in there. I guess with engine running, the heat, etc blasts/evaporates the incoming water out the fan hole from the engine. I thought maybe if the fan runs, it could blow away some of the rain water, but that supposedly comes on only after the car is stopped in hot weather for cooling. Well, anyway, mystery solved on how so much wash water/rain water can work itself into the engine compartment of these turbos.

 

Yep...gently. Then..as stated..remeber to remove before restarting. This is nit a problem for me as I always dry out the engine bay before driving.

 

Thanks for the great explanation. I am thinking about cleaning the back and wing with ONR, and washing the rest of the car with soap and water while placing a towel on the rear window to avoid any water going on the rear window. We should do a class action lawsuit against this nonsense

 

Placing a towel on the rear glass won't get it. You gotta close up/cover gap at bottom of glass to metal. Pushing the towel into the slit that runs to the bottom of the glass between the metal and the glass (about a1/2 inch wide opening) will stop run off into engine. Before you put that towel in the slot, open the engine lid and put newspaper on the engine and wet down the glass and you see the flood of water pour onto the newspaper.

 

I use onr all the time on my cars with great success. Just follow their instructions on their website and you won't have swirls.

 

And the neighbors....

But it works GREAT!

 

This was one of my first posts on this forum. Unbelievably stupid design on Porsche's part. The engine literally got soaked the first time I washed it. Now, like others, I put a towel over the engine when I wash. Still gets wet but much less. Also, since you have to open the engine lid to get the towel out, as soon as you cose the lid, water invariably drips right back onto the belt and you will get squealing and loss of power steerin for a few seconds on start up. I asked the dealer about this and they gave a typical "what are you talking about, oh that's no big deal" response. I asked an independent Porsche shop (don't flame the messenger) and they said that 911 turbo is not driven as an everyday in Germany and it's not designed for driving and parking in the rain. He said the belts eventually break because of the water, but the alternator is ok getting wet. So much for Porsche's intensive testing

 

This guy put me onto ONR - that's all I use now and no hoses (no water in the engine compartment!). He's local so if you ever need a great detailer, give him a call.

Sure does!
