My question:
Can/Should I install exhaust cover and turbo blanket on this engine? I’m thinking tin is the way to go due to the oil dripping type of engine (possible fire hazard). Lol… but maybe turbo blanket is ok? Let me know, I’m getting to hot at stoplights! Lol 😂 Thanks everyone, Ryan

I would use tin to isolate your exhaust muffler from your engine bay. When you are sitting still, the heat of the muffler is rising right into it.

On a type 1 the piece of tin you are missing is called a breastplate, for yours it will likely be a fabrication.
Thanks for the insight! Would you use Tin, or blanket to isolate turbo heat, or just leave it alone?
