1G Consequences of copper spray and possible valve contact on “new” motor?

[ItsJustin]

Good morning guys!

New to the DSM world but have been lurking on these super helpful forums for a few months now.

I picked up an allegedly freshly rebuilt, never run 6-bolt off of marketplace for super cheap, so I couldn’t resist the opportunity to swap it into my ‘87 Mighty Max.

Obviously I don’t trust stranger’s word on whatever they’re selling so I decided to pull the head and have a look at everything for peace of mind before I start boosting around.

It appears than on assembly, the dingleberry who put it together copper sprayed literally everything, valves, pistons, some of the cylinder walls, oil journals and anything else.

I don’t know these motors at all, the initial plan was to run it for a couple hundred miles at a decent clip to seat the rings then change the oil and go about my life from then on out. Do you guys see any potential issues coming out of a coating off copper spray in the combustion chamber? I know the directions on the can specifically mention to avoid spraying into the cylinders.

Additionally, it looks to me like some of the valves have kissed the piston as well, seeing as the copper has been removed from both the piston relief and the valve itself. I didn’t see any warpage on the valves but of course that’s just me eyeballing it. How badly bent or damaged do the valves have to be for it to be a serious problem in these motors?

I’ve attached photos so you guys can see exactly what I’m referring too

Thanks for your time!

There is no way.....

I am assuming the engine was never run, definitely remove all that copper stuff. An organic solvent should do it. As far as the head is concerned, I would have it gone through. It might have been resurfaced past the limit so a much thicker head gasket might be needed. In all honesty, I would take apart EVRYTHING including the bottom end. So many red flags.

Everybody will have an opinion, here is mine. Tear it all down. Send the head out, those valves have touched. You wont know if the calves are bent unless they're looked at. As for the copper spray i would clean it all up. I have no opinion on the use of copper spray. I do not use it.
