Does anyone get their engine parts coated with materials such as this: http://www.hpcoatings.com/engine_coatings.htm ? I was contemplating doing so for my rebuild. Does anyone have any advice/comments regarding any possible cons (aside from $$) by doing this? Do you think it would make hypereutectic pistons slighty more detonation-tolerant?
This a post from an earlier thread started by Jim Burek on coated cams & bearings that I replied to. i cannot answer as to if it will help keep the hypers living longer. The coatings will reduce friction and heat soak if applied properly. george Kingfish Registered User Join Date: Mar 2002 Location: Auburn, Maine Posts: 82 -------------------------------------------------------------------------------- Steve, I did my own main rod bearingss, oil pump gears and lifter bodies (exterior body only) and pistons with DFL. Also ceramic coated the piston crowns after massaging them. Techline coatings sells water based DFL and Ceramic coatings for internal engine components as do other vendors. To do this you need: CLEAN compressed air @ 40 psi Small touch up gun Coatings Acetone or other non petroleum based cleaner (see supplier spec) 150 grit aluminum oxide media small media blaster Oven capable of holding your components and baking to 350*F. Do not use solvent based coatings in any oven that you will prepare food in. Basic overview: Prepare the surface such as as any polishing and metal removal. Clean the material Lightly blast the material to be treated with aluminum oxide Clean the material Spray the product Air cure Heat treat in the oven. If you are not interested in the DIY method Jim Burek and several other vendors perform this service. George __________________ George King 1987 Regal 462 TA Al St1 heads-4 speed-3.42 posi
