Just got reply this morning. Makes sense i suppose but otherwise is there any way to clean inside while its split or is there any point?
Hi James,
Vapour blasting is very gentle and virtually non abrasive to the surface.
However, I wouldn't recommend to do it before the engine block is complete.
The vapour blaster still uses media and you risk that some of it stays in the oil galleries.
When the block is built and sealed I could seal/blank remaining ports and openings without any fear.
Hope it helps.
Cost for the job would be around 300 euro.
Regards,
Martin
