Engine not run for years

Indeed. What would be more likely is a rod snapping and blowing the bottom off ..... although being abducted by an alien is probably slightly more likely than either of these alternatives.

I had a Peugeot cam belt tensioner let go, there was an almighty bang. I opened the bonnet and could see a busted rod sticking out of the block. When the roadside recovery was called he went down the script, I stopped him and said I could see the rod sticking out, he then said "Ill send the truck"

Local bloke asked me if I could fix the 'missfire' on his Sunbeam Rapier (yes,this was a while ago, maybe '72?) A 'quick' look noticed a hole in the block... were the bust rod had punched a hole. I happened to have ac spare Alpine engine, so fitted that. + a bit of advice. Two weeks later he put in a ditch at speed. Well, it was Norfolk.

A bit like this one ..... after I pushed the rod back in. :ambivalence:

Despite having a good imagination.. I looked at a 1GM that had been left for 10 yrs, supposedly winterised. Short story is, the exhaust valve and seat were corroded enough to require replacement.

On the other hand, I had a 1GM10 which had been in regular use and the exhaust valve and seat were corroded enough to require replacement on that.

Impellor was OK, but replaced. All general servicing was done. Started fine and worked for about 30 (?) hrs, before suddenly overspeeding. Don't know why yet, but compression is down. Currently being replaced by a 1GM10.

Waterlocking usually bends the rod(s) Been there and fixed it. Only time I saw a really wrecked engine risking peeps, was a trencher that ran away after a bust chain took out the injection regulator. Everybody ran away and it showered bits when it blew.

It was not the head, but stuff flying out of the crankcase. Heads are pretty well fixed down.

You are right, they useually are.

However, during a Grass Track race at Cassiobry Park near Watford in the early 1970's my old racing collegue Bill Davies had his JAP engine blow up on the start line so comprehensivly that the exhaust pipe held the front of his cylinder head, the back part was hanging on the carb and throttle cable and lots of bits of cast iron were embedded in the soft inner parts of his thighs. The spark plug-and the HT lead and the bit of head it screwed into-were never found.

The Start Marshall, the late Arthur Sweby, bent down and picked Bills piston up-he put it down a bit sharpish, it was quite hot!

Easiest way to get oil into the bores is through the inlet manifold. No need to remove injectors. I screw the valve adjusters down enough to hold them open so the oil gets in, and re-adjust after.

Methanol?

Methanol?

Oh yes-and 14:1 comp ratio with a brave choice of ignition timing.

What let go was the small end eye of the conrod. The piston whacked the head so hard it exploded.

Bill won the race-and the tenner prize money-on his spare bike. He was a real character. He got a pilots licence at the age of over 80. When I asked him why, he said a bloke down the pub said he couldnt-so he did!

I knew I was having a good day when he finished behind me, even when he was in his sixties, 20 years older than me.
