One day I thought I'd get all fancy, and powdercoat all the tin on my 36 hp engine. I did it, and now have 2 questions:
1) Does any one know of a good method of painting the intake manifold close to the original Gray. Powdercoating doesn't work (only good till 450 degrees) It all flaked off like cheap cornflakes in 10 minutes. (Looking forward to pulling the engine out again to redo this...)
2) The engine didn't leak and now there is oil everywhere. My only guess.. is that it is coming out behing the pully and flinging up. The fellow who powder coated the pulley also painted the backward threads on the pulley, that keeps the oil from coming out... could this be the problem and should I take the pully out to strip the paint off...??
Any comments would be appreciated. thx |

Look in Hemmings, there are a number of places that do high-temp painting on exhaust/intake manifolds.
Yes, strip the powdercoat off the threads of the pully. I'm surprised it even fit in place. |

| I had the exhaust on my 36hp engine ceramic coated at a local specialty coating shop. The ceramic coating will take the heat, but it will also chip if scratched, unlike powder coating. The ceramic coating comes in a few colors, but gray, silver and black were the most popular choices. |

| I've heard of a few people using POR-20 but I haven't heard about long term usage. |

When you go to strip the powder off the pulley use aircraft paint remover. It's about the only thing that will touch the powder. You may have to strip the entire pulley and have it redone and have them tape that portion this time when they go to paint it. When you strip the powder off make sure to wear good rubber gloves and safety glasses. I would also recommend a sink near by as this stuff will burn your skin in a heart beat. As for the intake powder will only take about 300-350 degrees depending on the powder formulation used for extended periods of time. I would recommend the metallic ceramic coatings in that case just be careful putting the motor together and you shouldn't have any trouble with scratching. If you have any more questions about powder coating let me know I have been around it since I was about 10 years old. Hope you get everything fixed okay.
