#5 sprak plug was crushed, going to grab an L26 tomorrow, going to re-use my headgaskets obviously, any tips on the best way to clean the copper spray off them ???
 


Might be able to use a soft brissled wire brush. I think it has brass wires on it. I'd try a small section with light preasure to make sure it won't mess up the gasket any. That's about the only think I can think of. Any other type would be to harsh. Let's us know what you come up with.
 
It seems that no one has because this thread hasn't been answered on in a couple of days. Just trying to be helpful. Take it as you will.
 


I think I might just try scotch brite, or possibly a parts washer !

We'll figure it out this week and I'll update. I think a brass brush may be too hard for the ehad gaskets, but I do use it clean the block and heads.
 
Yea, I didn't even think of a scotch bright pad. Probably would be the better choice. I was just trying to think of something that wouldn't be as aggresive as a regular brush, but yea, I think you hit it good with the scotch bright.
 
I donno why anyone would risk reusing head gaskets muchless any other gaskets. Pulling a set of heads again after finding out your reused head gaskets failed is a pain in the ass.

I've known of many people on several motors who had nothing but bad luck reusing MLS style gaskets. I'd just buy a new set and be done with it. MLS can be a ***** to seal anyways, muchless reusing them...

never had a problem sealing them. Copper spray FTW.

They only have 1600km's on them so I'm reusing them. I was only running 4-6psi during that time so...
 
The first time I installed mine they went in dry.

I reused them the second time, and this time as protection I used copper spray.

I would suggest that you remove any loose or flaking existing copper spray with a brush, and make sure you clean them well with a parts washer after wards. I would then prep them by giving them a good wipe down with some degreaser (such as lacquer thinner) and once dry, start building up the missing or low spots with some fresh new copper spray. You know like the first time you did it, keeping it thin and even coats and avoiding drips at all costs.

Make sure you also prep the heads and block well and you should be fine.

Very bad idea to use a scotch bright pad anywhere near an open engine, no matter how careful you are. Trust me I have see failures from this.
