Anyone have any experience of cleaning up a aluminium cylinder head - particularily removing the old engine oil and other crap from the inside, and cleaning out the hydraulic lifters? What would you use to ensure that any steel parts don't rust?
Also, what is used to decarb the combusion chambers, valves and piston tops?
And finally, what is the preferred way of cleaning the faces that join via gaskets? I'm planning on using one of those green pan scourers, so long as it doesn't start removing any metal from the faces.
Cheers, Andy.
