After taking the off plenum to check its integity for leaks I also needed to remove the intakes for new gaskets so I figured WTH, let's clean it up It was dirty to say the least but after 3 hours of gas & Brinkmans brake cleaning stuff the grease is gone & it's ready to paint. I'd like to do a Hammerite black or orange on the tin & opposite on the intakes & various other components. Orange tin & black runners. I dunno but sumpin like that.
Here a before & after of dirty & clean. Mind you, there is some surface rust showing on the tin in places but it wasn't visible until I removed the grease
If it doesn't run better at least it'll look better
