No carb insulator gasket?

[mikealeus]

Took my carb off and here's what was between the carb insulator (the orange stuff) and the intake manifold. BTW I need a new carb insulator with heat shield if anybody knows where I might get one. Had no idea they were one piece. Well at least they were at one time.

sor has them AFAIK cant be more than 50-60 dollars

1. The gasket is embedded into the insulator. There is NOT a separate gasket required per se.

2. It's a big no-no to use silicone between the carb and insulator.

3. I think I have a box of those insulators in my back room at the shop. Someone else called me on Friday for one. I've got to remember to look for that box.

Get a used one from Mark. Used is fine, as long as the top and bottom gasket faces are still intact.

Worst case, Toyota shows still available:

Part Number: 2191261033 List Price Core Price Your Price
INSULATOR, CARBURETO $52.50 $0.00 $39.90
Part number 2191261030 was superceded by part number 2191261033.

What about silicone between the insulator and the manifold? That orange stuff in the picture is a very thin rubbery material and it is unlikely (but not impossible) that this had ever been removed since new.

Jim, thanks for the part number I need to call CDan about some other parts so will inquire.

Silicon RTV is not gasoline proof. With exposure to fuel, it turns to a gelatinous gunk that does not seal and can get sucked into the engine.

The instructions say something like "excellent for sealing coolant & oil. Not recommended for exposure to gasoline".

Use a good gasket and RTV is unnecessary.

Now unavailable according to Cdan.

Thanks for posting that. Now we know.

Is the heat shield really necessary? Mine is also cracked like the picture above and I was wondering if I can just get rid of it. I don't want to spend the $129.44 from SOR for a new one. (For a 5/76 FJ40)

Thanks.

I have read conflicting statements on this subject. Some say is OK without it in cooler weather, but can be a problems in the heat.
