Request: Oil Pan heat wrap?
 

Hi all,

Looking for some help from the community regarding the application of aluminum heat adhesive to the oil pan. I feel like this is one of those things you have to think a bit before attempting to get a clean application - has anyone seen a template for cutting / an existing DIY of best practices?

Anyone with the Tomei UEL - what were the instructions like for the heat wrap / was it cut to a specific shape?

Thanks!

Unbolt your headers, clean the oil pan with a cleaner (Simple Green), and stick the adhesive shield on it. Cut where you see creases and overlay the heatshield. Cut a hole out for your drain. While you're down there, wrap the lower radiator hose and zip tie the ends because the adhesive won't stick on rubber very well.

As for a temp plate, I'd like to see one also. Don't think I'd redo mine since one 12x12 sheet pretty much cover my oil pan.

@MyRx thanks for tip on hoses. Hopefully I can do this without unbolting, I think OFH has enough clearance

I am being a bit lazy and naive, but I assume this is to keep heat out of the engine bay, or what?

I was going to ask the same question.

It's also going to keep the oil hot, which may be less desirable than keeping the engine bay cooler.

It's to reflect radiating heat from headers from being soaked up by oil pan - this will prevent the oil from being unnecessarily heated, particularly in track applications where oil temps and pressures are really important. OEM headers have a metal heat shield whereas most aftermarket ones don't. The tape would be used to mitigate some of the resulting heat issues.

But wrapping the oil pan will cause it to retain heat, no?

I think the net result will be cooling under track usage as it is thin and it is aluminum coated on the outside to reflect.

For that to be true the adhesive would need to be thermally conductive otherwise heat from the oil pan that would have radiated out will now be trapped.

Also, for it to work it will need to reflect more heat than it retains.

Good luck with the experiment.

@jvincent Tomei actually packages it with their uel headers, hope they did the testing for me :) I have the OFH so km thinking of adding it to my oil pan as well.

A good ceramic coating on the headers will do even more to get the heat away from the engine bay.

@stugray absolutely, but a more expensive endeavour :)

One would hope they did their testing.

I'm assuming you have before numbers on oil temp, I would be curious on the after.

Oil Pan Wrap
 

The oil pans ability to dissipate heat IS diminished, especially by thermal barrier tape, so I did not cover the entire pan, just the area next to the closest header pipe at the front of the pan.

I did it, it worked. Saw much lower oil temps at the track.

The Tomei supplied tape I believe is a thermal barrier, I used gold heat reflective tape, (It's only temporary for now, I'm going to a jet engine thermal barrier plate between pan and pipe, not touching either).

I believe the Tomei tape retains more pan heat than the gold tapes non thermal (just heat reflection) tape, so IMHO it would be prudent NOT to cover the entire pan except in the front only, and leave some pan surface free.
