Brought a piston into work

2 litre twinspark.
Failure mode was exit block front at about 70mph on a DCway
Or, as no-one troubled to warn me before hand, seems the exhaust on these runs down the front of the engine and backwards through a recess in the sump, putting the hot exhaust just under big end #3. So if the car has ever been run on cheap oil, or run low (not by me in either case, I'd like to point out, I only had it a few weeks!), the oil in #3 gets cooked out...
There was certainly oil in it .2 secs beforehand, a very impressive cloud behind me.
Oh, also turns out to be an effective, albeit expensive, way of getting that Audi tailgater off your arse
Ahhh, the classic 2 litre TS eating its big end. Also related to running on low-oil levels mind you (which is why i keep a really close eye on the oil level of my 1.6 TS)Failure mode was exit block front at about 70mph on a DCway

That is a big doubt for me though, i'd love an alfa with a 2 litre, but rolling the dice on the big-end lottery is scary.
A valve from one of the first cars that I sold, a used Clio 172, the guy who bought it was a right jumped up little s
t all full of his own self importance. About a week after taking delivery the cambelt snapped, the guy claims he was sat in traffic and it just went, given the state of the engine and the valves he was most likely ragging the arse off it, it was believed that the accessory belt jumped off its pulley and snagged the cambelt, which whilst isn't common, does happen on those engines, anyway it was all repaired under warranty.
The valve has been with me for (I said 20 years in my original post but it won't have been that long, thinking about it) for about 15 years.

Confession time. During the 80s I built a number of 750 Triumph and Norton engines for fast road and race use, used pistons that had a compression ratio of up to 12:1 and they look big and beefy with high domes and long skirts. Three months ago I help someone take apart a Honda racing engine and the pistons looked nothing like what I was used to, they had no skirts, next to no metal below the rings.
And then the bike owner showed me a pic of the NR750 racing engine. Without the rods I am not sure that I would have recognised that as a piston either.
I knew they we oval,pistons, but not that they had twin conrods! Thank you for that.And then the bike owner showed me a pic of the NR750 racing engine. Without the rods I am not sure that I would have recognised that as a piston either.

One of the trinkets I am looking for, for my mancave, is a mahoosive piston from a train or ship. The hunt continues.....
Basically a V8 but staying just about within the FIM's 4 cylinder rule.
A great bit of engineering.
Reading this thread reminded me of Mr Weallans my old history teacher from the 1980s.
We were studying WW2 and when we got to D-Day, he arrived in class carrying a bloody big piston from an allied armoured vehicle.
I remember we never actually got to learn about D-Day that lesson, but by the end, both girls and boys knew all about inketbvakves, exhaust valves, compression and much more.

That's excellent. Just a shame the electric cord couldn't pass down the length of the crank.

I made my (future) brother in law a lamp:
Most people that go into their house have no idea what it is.
Mark 2 is sitting in my garage awaiting shot blasting and powdercoating, it's an identical crankshaft, welded to the old clutch cover from my Nissan 350.
I also have a turbo from a 9.0 Scania to turn into something. Not sure what yet.
That's great! A mate of mine made a wine rack out of worn out plough metal, it was flippin' heavy! I wish I had the artistic streak to do this sort of thingMost people that go into their house have no idea what it is.
