On the basis of what the AA have told me the problem is a blown cylinder head gasket ie a component of the new engine.
So, yes, it's a problem with the new engine.
Thanks Jenny, that's useful and is in line with my understanding of the law too (for what that's worth!)
One follow-up. The situation at present is that my local Ford dealership ow has the car, but except for a very quick check to see that the root of the problem was not the same cracked pipe as the 1st time (for which Ford have since issued a general recall), the are refusing to examine further unless I first accept responsibility for all costs.
This to me seems most unreasonable and I am very reluctant to do so.
What are your thoughts?
(Having the vehicle towed else where, however, would also be expensive!)
OK. Thanks for that Jenny.
One last question, before I give you an 'Excellent' rating.
Thinking ahead, even though you say the Warranty issue is not crucial, I guess that they may still try to insinuate that the fact that I missed a service implies I was not caring correctly for the car, and that this was what caused the problem.
My view , however, is that since the only missed service was from BEFORE the new engine was fitted, and it has been serviced to schedule from thereon, this argument is weak/falacious.
Does that sound reasonable? (Or is it too technical for you to comment on?)
