Re: Getting Engine Paint to Stick

I would say you probably have a tuning problem as opposed to a paint problem. I did to!

First check to see if your not running to lean? Lean will cause excessive exhaust heat. Next timing, several people retard timing to compensate for engine knock from todays gas. Retarded timing will cause excessive exhaust heat. Next what spark plugs are you running? With todays gas the plugs that were recommended in the 60s are just to hot today, causing high exhaust temps. Going by Champion plugs, recommended was RJ14Ys I use RJ10Ys, exhaust temps are a lot lower & I don't experience gas boil off or vapor lock as much as I did with the hotter plugs. Trying an even colder plug should be addressed for run ability or performance purposes if your engine can handle them. Also the colder plugs will help a lot reducing engine knock allowing you to advance your timing! Just something to look at.

Subject: Getting Engine Paint to Stick

I've always had a HUGE issue getting engine paint to last...especially

on intake manifold crossovers.

Any suggestions for specific preparation procedures and or a specific

type or brand of paint to use?

I really hate having to re-do the paint on my intake every other year

to keep it looking decent.

Thanks!!
