Tidy up the sagging engine bay insulation in a 964

I also used a piece of aluminum from home depot. Sprayed it black and used plastic/nylon nuts with regular washers to hold it on. They aren't threaded the same but since they are plastic you can just re-thread them as you twist then on. They held better than the originals. Also used cardboard to make the template.

Fellow Rennlister Fred Nelson emailed me his instructions for making and installing an engine pad strip some months ago -
"I can tell you how I made it though. I did it with the engine out, so it was easier than with it in.
I used cardboard to make a template using the threaded studs that hold the large round plastic nuts.
I made it about 2 inches wide and it had a slight curve to it to conform to the foam blanket.
I notched it to clear the hinges then smoothed the notches to make them curve around to eliminate sharp edges inside and out.
Then I traced it to the aluminum sheet. I used .040 aircraft 2024 because I had a piece handy.
I cut the sheet, smoothed the edges, then I drilled the holes carefully to match the centerline of the studs.
Then I enlarged the holes with a step drill to about 1/2 inch so the collar on the nuts would fit through the holes.
I polished it a bit to make it shine and installed it. I replaced the nuts with new so it would look good."
Of course, being quite hopeless at such DIY, I haven't tried. Where's that Babalouie when you need him?![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

I noticed that the studs that hold the insulation form a slight arc so dont think you can drill a series of holes properly spaced (See OP's second photo - Outer studs further back than middle two studs). I found a 36" x 2" x 1/8" piece of aluminum at HD. After getting the holes properly aligned and drilled I slightly bent the aluminum to fit the shape of the bay. Once I found the fit to be good I primed/painted the aluminum flat black and installed. I didnt have much issues getting screw on pieces to fit. Been working good for the last few months.

now a proud member of the tidy engine sound blanket club. I ordered the strip off of eBay back in April and finally got around to bending (vise) drilling and installing it. The tolerance for the drilled holes is large since the push-on buttons are so wide across.
