When my motor was rebuilt and all the emission crap removed we had to block off alot of the vacs. Now my questions is does anyone know where to buy a better grade of block offs as mine are starting to split due to the heat?

The little black nipple block offs you get from Autozone are not cutting it.
I think those are rubber, so I guess I need to upgrade.

Thanks

 

Squirt silicone RTV in the fittings.

Get the different colored vinyl/plastic? ones.
Think you can get them from autozone and the like.
They seem to last forever.

 

Zip tie silicone hose to the nipple, then plug in a bolt that fits snugly in the hose on the other end and zip tie it as well

But then it's hard to prevent yourself from just squirting in silicone RTV as Ted suggest
