Quite a bit to update!
I missed my first race at Anglesey after a little mishap with my aux belt.
I put a new clutch in. Had the engine back in and started it up started fine and I was giving it a once over when I thought something wasn't right with the aux belt. Then I saw it was shredding itself so went for the key, but it was too late. Before I got there it went tap, tap, tap and stopped.
I timed it all back up the next day but it wouldn't start and had 0 compression on all cylinders
I priced up new head set, bolts, cam belt kit and seals and it was approaching 300 quid. So I decided I'd just give my spare engine a try as it only needed a cambelt. It was a bit of an unknown quantity though as it had no history and a hole in the sump. Although I had checked the big ends to make sure there was no oil starvation damage before I bought it.
Pulled the old engine apart to have a look at the damage. As good as could be hoped for really looks like just inlet valves although I haven't checked it out properly.
Interestingly after 138k miles it still had the original honing marks on the bores.
Swapped the sump and my ARP rod bolts to the new engine. Bearing clearances looked good and no significant scoring on the journals.
New engine all together and ready to go back in.
Got it in and started no problem. Have done about 20 road miles and all seems OK with it.
Now I need to put my 428 cams in it, as that is what my ECU is mapped for, and fit a new cambelt kit. There was a suspicion that my 428s where from a "dodgy batch" so I decided I'd take the time to dial them in this time and see if the timing marks are machined incorrectly.
That's were I am up to at the moment. Hopefully get the cams and belts in this week.
Have entered Mallory on the 26th of August, can't do Combe as I have a prior arrangement.
