took the head off my new engine for inspection at the weekend and found some interesting things.. the head is defonatly a turbo head, with double valve springs and wider exhoust valve stems.
the engine number is 12HA85, wich i think comes back as a 1275 MG..
nothing i have found i feel is too worrying, the bores seem verry clean with no scratches.. the pistons are still in one piece, lol there is a lot of build up of "sut" on the pistons tho...



the head ..




when i took the plugs out, cylinders 1 and 2 look verry light and dry, 3 and 4 were verry black.

the carb has a lot of "blackening" towards the cylinders and is clean facing towards the turbo, i really cant think what might have caused this?




over all what i found i am so far pretty happy with, the gasket was intact and was a bk450 (are these what MG used as standard?)

also the pistons have a B on them, that is all i can find, does it mean anything? they do have a quite a large dish on them, is there any way to tell if they are turbo ones?

i do have a feeling that it was an MG engine with a turbo head and bits put on then put back in a metro turbo, if so i can work around it but so far looks like no damage was caused, thankfully:)

any ideas/opinions would be great :)

Thanks! Dan

Looks like a pretty normal stripped down well used engine to me........

no news is good news hehe. any ideas on how to tell if its a turbo engine or not? i know most dont agree with using an old engine, but i am going to be rebuilding another engine whilest this ones being used as a bit of a tester. as i dont need it as an every day car anymore i am in a good enough position to do this now:)

thanks. Dan

the carb i rebuilt tonight was just as stained inside, it comes off dead easy with a squirt of carb cleaner.

i dont 'need' a daily driver now as i walk to work (5 mins) however i do need a daily driver to drive to the garage to work on the non daily drivers, how sad...LOL

What Nic? It's very easy to pour MrMuscle in your tank. Whether you should do it that's a totally different question :)
