So I need to DIY some heat shields for my engine bay. I plan to fab up a shield for my master and my lines affected by the heat. However, I had some questions to see what others have done. I have spent a few hours on google today going through old MT.net threads on shields, turbo blankets, DEI wraps/tapes but I wasn't able to find any examples of the following....

1. Does anyone use any sort of wrap or blanket for their Brake Master Cylinder? I know I could use the DEI Gold Tape, but I like the idea of being able to check my fluid levels in the reservoir. I was thinking a DIY blanket or wrap could be removed for eaiser access to check fluid levels.

2. I plan to swap out my rubber heater core hoses for some silicone ones. Has anyone also wrapped their silicone hoses? I wasn't sure if doing something like a DEI titanium exhaust wrap would be worth my time. The other idea I was tossing around was using the DEI Gold Tape for the silicone hoses.

3. I saw a few people melted their dip stick. However, I didn't see much on alternative options. There was a thread or two that suggested wrapping the stem, but I fail to see how that helps keep the plastic from becoming charred yellow goo (similar to pics in other MT.net threads).

Any advice or snide remarks are welcome.
Thanks

You shouldn't have to wrap the resevoir itself, just the metal lines that get close to the turbo/DP. One thing you could do that would help is build a heat shield (old license plate if you are cheap) that sits along the edge of the shelf between the turbo and the brake components. That should solve any problems there.

The only time I had problems with my dipstick melting was when there were cracks in the manifold leading to heated gas being blasted at the dipstick. It melted my speedo cable too. I haven't had any other problems there.

Can't help with the heater core hoses since I don't have one but the PO installed a quasi-coolant reroute with the line coming off of the back of the head looping around to the front. This hose is just rubber and goes along the firewall with no issues from the exhaust heat.

Yeah, that was at the top of the post. The old engine ran something similar. While it helps, the radiant air in the area was more my concern. I plan to run a shield, but was also wondering if a wrap around the master has been done.

Here is a pic of the previous setup. I am going to take queues from this and other heat shields I have seen posted in threads on my google searches. I like the idea of aluminum and either a DEI Gold Wrap or an Insulation Option like their transmission tunnel material.

Ah, sorry I missed that part of your post. Unless you are having problems with your brake fluid boiling, I wouldn't do much more than the shielding you show in that picture. Hot air in that part of the engine bay doesn't have anywhere to go but down below the car anyway so the heat shields blocking the radiant heat should be enough. Shielding the dipstick from the external wastegate might be a good idea too
