Thanks Vass. I’ve taken the head to one of the cylinder head repair shop and the guy will let me know if it’s still reusable or not after carrying out 3 tests on it. Then he will carry out to resurface, clean, and replace the valve stem seals for me. Sounds like a good old man with heaps of great reviews. One of the shop in town I rang up quoted $1100+ to do hardness/pressure test and valve stem seals replacement (not including other things) and the guy I took the head into said that’s far too expensive. It was the very first time I’m taking the head for the tests so I said I’m not aware of the rough prices these days but my boss at our workshop, the garage next door all said that’s too much.
The old man said about $600+ at the most and he sounded quite reasonable and explained to me what he does etc…
Well I guess I’ll find out soon.
