Oh bother, we've just snapped the crank on Robs car!!
Hmm, this one is going to make getting to TOTB a little on the difficult side.
We were setting Robs car up last night on a private test track (called the M5
)
And fook me it was flying, there is no reason for any astra to be going that quick, lol
Anyway, pulled off the motorway and as he dipped the clutch at the roundabout to come to a stop the engine cut out.
Hmm, "strange" we both thought, as there was no hint the engine wasnt running fine (quote the opposite in fact)
He went to restart it and you could here what sounded like the starter spinning but not the engine turning over.
We pushed it down to a layby and got it half up on a curb so that we could get underneath it, and took the cover off between the box and the engine so that we could see the flywheel, as we rocked it back and forward in 6th gear we could see the flywheel moving but the cambelt end of the engine was doing nothing, the flywheel though was still visibly attached to the crank (no loose bolts poking half out or anything).
Sadly ive had to go into work today as we've got a bit of an emergency on here, so Rob is now on his own today trying to get a new crank into it by this evening, worse still he is only allowed to work at the workshop till 6PM at night (its in the lease), so its not even like he can pull an all nighter on it if he wants to.
Fingers crossed for him but its not looking good for us running at TOTB now

Update:
The crank itself is actually still in one piece, but its taken out the keyway on cambelt pulley, so the bottom end is turning over but not the head.
So not sure now if its damamaged valves/pistons or not, should know within a couple of hours hopefully.

We've made the decision to pull the head off now and replace it with another one straight away, we arent even going to strip it down to see if its done guides etc in as its wasted time.
So fingers crossed the pistons have survived it in tact, as thats the only thing we are stuffed for as no chance of getting hold of another engine and fitting it within the next 8 hours.
If the pistons are in one piece still and havent taken a hard enough hit to crush the ring lands down it will all go back together in time hopefully.
Rob is spannering away feverishly as we speak, hopefully its just a case of putting a new head on and getting the gearbox back on and it will be fine.

Shit.....gutted - was speaking to him yesterday he was well chuffed with how it was going too!!! 
Good luck to him - if it makes him feel any better - I did the same thing with a cam pulley & everything was ok once I replaced the woodruff key!!! Fingers crossed!!

Andy, Top end damage we dont care about, we can just fit another head (we both carry spares of that sort of thing!), its just if the pistons have had a hard enoguh whack to crush the ringlands thats it an issue.
We're in the hands of the almighty now in terms of what its done, nothing we can do to effect it now
There wasnt a massive amount of noise from it when it happened, so i reckon we will get lucky on it

Annoying thing is i cant even get over there to assess the thing for him, and Rob doesnt have a massive amount of experience with engines, so if there is anything else up he may not notice it

Chip.....surely though just whacking a woodruff key in & slapping a belt on would take him a matter of minutes & may save a hell of a lot of stress in the long run???

Andy, luckily calibra pistons are on a par with cossie ones, they are forged Mahle ones as standard.
So fingers fucking crossed!
Just thank fuck that it happened at low speed/rpm as thats obviously lessened the risk of it being major damage.
Poor Rob, he has put so much time and effort (and money, lol) into getting this car ready for TOTB, and now this happens.

Hmmm, nasty. I've seen it happen on a few cars where the keyway has snapped but it's only slid around a few degree so everything has been fine, just poorly running.

Even a compression test sometimes doesnt really give you the answer, the guides could be starting to crack up but look fine at starter motor turning speed.
Replacement secondhand head seems like a safer option.

The good news is though, it was going like a coont, so if it comes back together ok, im positive we can crack a 12 on sunday

Fooking typical, i wanted him to build two Z20LET gaskets up into one (soundsa bodge but they are multilayer steel ones so you can put two centers between one set of top and bottom layers without a problem so its not like using two normal gaskets) in order to make it thicker, and between the 5 vauxhall dealers in the area they only have one metal headgasket between them
An they cant rustle up a complete set of head bolts either
So gutted cause ive got a spare set of ARP bolts and a far better headgasket but they are too far away from him to be useful
So its going to have to a standard thickness gasket and a set of pattern headbolts.
Not what you want on an engine like this

By the way, Robs resolve hasnt changed, nor has his fondness of this event.
So whatever happens this weekend, we will be back next year with a properly built engine that i will spec for him to get the results he really wants, it was never this year we were expecting to do especially well anyway of course on such a tight time scale and with a secondhand engine, but I still really hopes he can make an appearance and get a midfield finnish so that he feels he has got something back for all his hard work

He should have the head off soon and have at least a good idea of the level of piston to valve contact that has occured.
coont so close to the event
