i need something that makes a good gasket to use on my tmap sensor that goes into the intake manifold. im getting a horrible boost leak from there. i started using the copper gasket stuff from permatex but it did not hold for me for the sensor. so i cleaned all that off. so any ideas on what i should use?

 

Honestly, if copper silicone doesn't seal - I don't know what to tell you.

 

Should have a O ring on it. It might need replaced

 

go to a thicker oring?

 

its got the o-ring on it and i put alittle bit of grease on the o-ring. im gonna try picking up a thicker o-ring and one of those small kits that have a few different types of gaskets you can cut out tomorrow
