OK this looks like it will need a head skim, but what has caused the gasket to dig in like this?
These are quite deep, maybe 0.1 to 0.2mm and look like compression marks from the steel edging on the gasket.
No other marks found on the head.
What are the recommendations, Skim it, or go for a fully reconditioned head?
Anyone in the northwest recommend a supplier, or engine workshop to try?
Thanks
Peter
