Good engine anyone?
...one day after it was MOT'd with flying colours!
Karen thinks I didn't over-rev it before the attempted overtake; I'm unsure since the sun was in the instruments & I was flying by ear.
But it wasn't the familiar roughness of the rev limiter (unless I hugely misjudged the road speed!) The car began to overtake, lost power slightly following a 'tinkle' before the usual blow-up. It was No.1 that went off at a tangent, BTW.
The car was still in VTEC when I took the head off. I freed it off that & found no.1 exhausts are jammed open. All other valve clearances seem spot-on. The cam gear is otherwise in perfect condition.
I heard someone else had the heads drop off no.1 valves at around 35K miles, so it might be that.
Anyway, any tips/pointers greatly appreciated!

Sorry to read this Nick. I hope you get her on the road quickly. Several of us use Furber Bros to source secondhand bits - that's who supplied PJL's engine, I believe.

Any suspicion regarding the MOT?
I insist I sit with the car, and go with it if it needs driving by anyone.
I also have a device coming out to monitor what people do with the car while not in your posession
I am a bit too paraniod though

Hope you get it sorted quickly and at least possible expense, Nick.

some brake testers dont compensate for an LSD so a road test with a tapley meter is called for
tapley meters register deacceleration by the use of a weight
turn it around it will then measure acceleration!
hope you source an engine soon
