I was trearing apart a friends engine tonight & noticed that there is some red coating on some of the parts.

A quick back story.  Its a Nissan 300zxTT.  The owner had an earlier Snow Performance WI kit that killed a Blitz boost controler selnoid & started to rust his stock steel intercooler piping so he got rid of the kit.  That was about 2 years ago.  During the time he had the kit he ran the Snow Performance Booser Juice, then windshield washer fluid & then back to the Booster Juice.

Currently his turbince wheels have a red/green/purple coating on them.  #2, 4 & 3 cylinder exhaust valves have the red coating on them, but the other cylindars # 1, 5 & 6 have the normal black mild carbon build up.

I'm not too familiar with WI kits & I know the Booster Juice is Red its self.  Are the red deposites anythign to be concerned with?  Any thoughts as to why one 3 of the 6 cylindars have the coloring?  I'm suprised any of it is there after 2 years (10,000 miles +). BTW he only runs 91 & 100 octane fuel, no leaded fuels.

Thanks for any thoughts you may have.

How are the nozzles hooked up? I think one isnt working.

I do not recall.  The Snow Performance system was deleted about 2 years ago & I had never worked on the car at that point.

I know different fuels and additives leave different colors and residues.  Like MS109 race fuel leaves an orange tint.  Torco fuel additive leaves a pretty heavy residue from what I've read.  As for different cylinders looking different, that could due to uneven distribution of the stuff sprayed.

Thanks everyone. The best I can tell its from addatives. I was concerned it might be rust and potentional failur in th efuture for the valve train.
