Engine out...
Following on from this THREAD...
It was a quiet afternoon at work today so cracked on with getting the sick engine out. 80mins (if you don't include the brew in the middle) and
this was the result...
Last month was the first time I'd taken it out since it went in 5 years ago. Now it's twice in a month. Hope this is the last time for a
while. Off to Oulton in the morning to give it to the engine builder. Just hope he can fit it in amongst his pre-TT work. Stoneleigh isn't
abandoned yet... but it's looking iffy.

Yep, it's the new one. Technically... it's fookin fooked!
Was going like a train at Blyton then mid-afternoon suddenly blew the coolant cap and over heated. Missing now on #4 and wet on than cylinder. So
head-gasket's gone at least. #4 only has a water jacket around 3/4 of the cylinder due to the timing chain gallery. As a result I'm told
it can run 20% hotter on that cylinder.
According to the engine builder... Get too keen on the fueling or ignition at full throttle or not pay enough attention to them at low/mid range and
you can get detonation and....
On the rollers last week we went spent ages getting the lower/mid range fueling right and went pretty conservative at the top end so I'm not
convinced it was our doing. Either thats wrong or it was already wounded when I got it or it was damaged by the very limited running before it went on
the rollers.
Whatever it's being fixed and I'd rather it happened now than in southern France in 9 weeks time.

when you map it, check the exhaust heat on each cylinder at the header then if your ecu supports it use the cylinder trim functions, it will allow
you to mess around with the fuel and advance on an individual cylinder to get them all running at the same temp.
