Had a sniffer test done as I was having an issue with air in my coolant tank - it would appear from the results I have an issue with the head gasket .
Has anyone used this guy before ?

Re: Gasses in coolant
Sorry to hear that - sounds as though the gasket has failed at the fire ring.
Which gasket is on the engine at the moment? What ever else is decided, the cylinder head is going to need to be removed. Have a look to see whether the alloy casting has gone soft as represented by an especially deep indentation from the cylinder liners - see picture below.
If the head looks okay, check the liners for cracks and for stand proud. The should be about 2 thou proud of the block deck, but if flush, you may be able to get away with the original elasteromeric type head gasket.
Back to your original question, no I haven't had experience with the chap in the eBay listing. Apart from not knowing how to switch off the caps lock, it seems that he knows what he is doing? See whether he can supply any testimonials. The other option would be to source a replacement cylinder head if that is where the problem lies.
Keep us posted!

Re: Gasses in coolant
Many thanks Rob
I have owned the car for 18 months - the history file suggests that the head gasket was changed 30000 miles / 6 years ago for a MLS type together with a recon trophy 160 head ( its a standard P reg VVC) - Will update once the heads off and the route cause found.

Re: Gasses in coolant
MLS gaskets have a reputation of not sealing that well on the fire rings, and need some extra liner stand proud. Standard 18K4FJ31 engines however were built to have a liner height that was practically flush with the block deck - and if this is the case, you'd be better off using the original elastomeric type head gasket.

Blimey! The original skim looks dreadful! It almost looks as though someone did it with 80 grit wet and dry! Reconditioned head now looks practically new!
