That's it, yep.

This was the condition of number 4 piston when I stripped down my standard engine this year. All the other pistons were fine.



As the head I was putting on had the tapping open for the heater take off, rather than blank it off (as it is unused on the Metro) I changed the plumbing of the coolant system to have a constant flow of coolant from the heater take off end of the head.

I removed the sandwich plate from the thermostat, and plumbed the heater pipe that normally goes into the sandwich plate into the heater take off instead.

^ we need to do this with the van.

If something is worth doing, it's worth doing half of.

MetroTurbo,
Found the exact same thing on piston four of the 1293 i stripped from my first mini with no real explination of why it may have happened.

Building a 1293 metro turbo engine at the moment for the project and have been reading about dry decking to sort the 'cylinder 4 cooling' problem that seems to cause this but it seems a lot of work.

Hows the engine after plumbing the heater into the heater take off rather than the sandwich plate ? been apart since ? guess all is well if not..

ta

Will my project ever be finished !!? hopefully you guys can help !
Its only been like 10 years in the making and I'm only just assembling my engine!

I've been thinking about this for a while, I was thinking of putting a bypass hose on the end of the block/head like a normal dry deck kit, but instead of completely blocking off all of the water holes through the deck, plugging them and drilling smaller holes through, so you still get a little cold water going up to keep the temperature down around 1 & 2, but more flow is encouraged around 4 as well due to the bypass hose.

I thought that way you could get the advantage of the flow around 4 bore and head, and still get a little up to keep the combustion chambers at the end of the coolants journey cooler.

Make sense at all?

I have only done something like 1500 miles since the rebuild, and I haven't had the head off since. It runs fine, but it ran fine with shagged piston fitted.

I'm not running mega power (actually less boost than standard recently, but that's another story), and I don't plan for more than about 130 bhp. I'm happy that it will be helping the flow around number 4 (the pipe gets scalding hot) and only time will tell if it is helping enough.
