interesting
interestingly I just received and email from a member of a UK jabiru forum, apparently its common knowledge in the UK that the generation 2 cylinder heads crack between the inlet and exhaust ports. This may explain why Jabiru refuses to return my heads after I stated that I would like an independent report as I didn't think their explanation that a leaking exhaust on one head caused all to overheat in the exhaust valve area, co-incidentally the business manager had no knowledge of heads ever cracking before!
