Don't know the correct technical terms, but the little arms that you can push, to close the PSE flaps, seem to be sticking a bit. Feels like I need to lubricate them. They seem to struggle a tiny bit when I "activate" the PSE.

Not sure what to use, because of the high temps. Hoping for some kind of long lasting grease. Any suggestions? Been searching. Haven't found anything definitive. TIA.

 

I have used this in auto and marine applications. Your mechanism is light duty. You need an easy-to-use lubricant that can also handle the heat and moisture.

Doubt you need anything fancier than this: http://wd40specialist.com/products/silicone-lubricant/

Lubricates, waterproofs and protects metal and non-metal surfaces, including rubber, plastic and vinyl better than leading competitors. Our silicone spray dries fast and leaves a clear, non-staining film that doesn't stick or make a mess, so it won't attract dirt. Effective in a temperature range from -100°F to 500°F, it's ideal for use on cables, pulleys, guide rails, valves, linkages, hinges, locks and more, and is 50-state VOC compliant.

Sounds as if your PSE muffler bearings need to be replaced, better run down to your local Porsche dealership…

Prob. just a few hundred dollars to keep that baby in tip top shape.







It's a joke, just a joke.

 

Interesting. This is exactly what I used last time, which was only about two months ago. It worked well at first, but wore off pretty quickly. I was hoping for something more along the lines of an actual grease. The PSE is functioning fine, right now, but you can feel and hear it working harder to activate. Kind of a grinding noise; this was alleviated when I sprayed the above mentioned short lasting lube. Thanks for the suggestion. I might go and spray a bit more on, in the meantime. Anyone have any other suggestions?



EDIT: Okay, I was using the penetrating spray before, which looks the same, as this lubricant. Got the silicone lubricant recommend above. Sprayed some on, and everything seems perfect now. All it needed. Thanks, everyone, for your help with this. If anyone has any "grease" recommendations, I'd still love to hear them. As far as function, though, everything works perfectly now. Probably just a matter of respraying once or twice a year.

 

I must have a dirty mind. I read PSE as **** star experience and you are asking for a lube for that.

 

I'd take some ultra fine steel wool to the mechanism and polish it. I expect the binding is caused by soot or corrosion build up. I doubt that a lube or grease was used from the factory.

 

Hmm, maybe. When my PSE went out I first took it in to the dealership -- who quoted me nearly $12,000 dollars (!) to replace the mufflers, etc., as they were obviously failing and the PSE had moving parts inside the muffler which could not be replaced.

Instead, I changed out the solenoid myself ($25 cheap) to no avail. So I took it in to my new indy, who replaced the vacuum actuators AND the solenoid, and in under an hour had everything working like new, for about $300. It turns out the solenoid I put in was defective, but the actuators were also shot. Absolutely no issues with the mufflers, despite what Porsche had said.

That was three years ago and 30,000 miles ago and everything still works great.

Based on my experience, I would suspect the vacuum actuators as weak/leaking/dry first and would not hesitate to change them out. I'm not a mechanic, but my indy indicated it really wasn't much of a job to replace them.

Incidentally, this experience is what drove me away from dealership service to independent service, and I've never looked back -- or regretted it. Either the Porsche dealership took me for a sucker, or else they made a colossally bad diagnosis, which drove me off and lost them an otherwise loyal customer.
