PTU Maintenance Idea

[dlemarbre]

Hello all. We are all aware of the challenges that come along with owning a late model SHO, especially keeping the PTU in good working condition...IE changing oil frequently, installing a plug for easy changes and watching for leaks so you don't loose all of the 8-10 oz's of oil.
The main culprit is it's location. It's surrounded by heat, exhaust, Cat, transmission...etc. which breaks down the oil and in turn creates failure.
So my question to everyone is...has someone considered covering the little SOB with a protective coating?
Maybe a high temp undercoating or engine block paint. Surely this would assist in the breakdown of the oil by blocking the outside heat source. It probably doesn't help that the PTU is made from a cast aluminum.
Thoughts, experiences?

PTU fill is 18 ounces of oil. In my experience, a water cooled PTU doesn't get over 190 or so in normal driving. It takes a while to get that high. Just change the oil every 30,000 miles.

Sorry. I forgot about the water cooled years. Still looking for anyone that's covered their PTU

Did it help and what wrap did you use?

 

[Chuck Johnson]

Yes and i used DEI wrap on the pipe and the heatshield armor on the cats

Wow! Thanks this is great. I appreciate it

PPE engineering sells ceramic coated downpipes if you have an extra 2 grand between the couch cushions. cuts back on the heat around the PTU

Though I still wrapped mine.

I bought stainless works downpipes, then got them ceramic coated, and the wrapped in DEI exhaust wrap. And my car has the cooler for the ptu. Works quite well now

Same after getting the downpipes coated and wrapped with a PP cooler things are much more under control temp wise. Well worth it, those cats even with the shielding throw some heat.
