Someone is shovelling some major bullshit somewhere about this.
You can't just burn a valve out trying to start a car. The temperature required to do that is too massive - you just wouldn't be able to get it hot enough without thrashing the bollocks of it. If it had a burnt out valve it must have been like it before.
So this garage just knew that it had a burnt out valve without taking the head off? Has he just put in a new valve then? What about the valve seat because if the valve had got hot enough to burn out it would take the seat with it. A new valve on a burnt out seat is not going to last five minutes. Plus you still don't know what burnt it out in the first place.
Plus how did trhey strip down and rebuild the metering unit? That's a precision instrument - you can't just dismantle it on the bench. What did they find wrong with it and where did they get the parts from to rebuild it?
There's a lot of stuff here that makes no sense whatsoever.
So is it fixed now?
