I am replacing my coils this weekend. Obviously will be replacing upper intake gasket while I am there. Doesn’t look like there is any use of copper sealant or anything but wanted to check with folks first.

 

I put mine in dry. No vacuum leaks.

 

You will be fine, but I don’t see how some copper spray would hurt. It’d help it to not slide around at least

 

Dry fit

 

Mine is dry fit but I don’t like how the gasket doesn’t match the ports.

so eventually I’m going to buy a junk yard upper and lower and a gasket and port match them. Maybe remove some rough casting slag etc. “garage p&p”
