Few Quick Questions - Engine Building
Turbo Mini Forums

I have just finished stripping my engine down for cleaning and rebuilding and have a few quick questions.

I will be building a mostly standard turbo engine for now (due to moving house) so will be on a budget!

Should I replace the piston rings? They are standard metro turbo pistons and the rings look fine to me

Secondly, do you think this crank can be used or is it F@?ked, the engine has been lying around for a while and the end of the crank has be bashed about abit!





And now the most important part, what colour shall I paint the engine red or green? It will be going in a MK3 Cooper S lookalike similar to my first car (below) I wanted to make it original'ish looking, although it will probably have a cossy intercooler upfront :)



Thanks Matt

Crank looks fucked to me. Rings deffo need replacing, I've tried re-using and it smoked like nothing you've seen before!

Red car looks good though.

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

Thats what I was affraid of, with the crank and piston rings!

Cheers matt

Schrödinger's cat - so which one am I ???

Sorry, i meant what colour shall I paint the engine.

I bought the engine off a friend of a friend for £50, think its been lying about on a farm for a while, but it is a genuine metro turbo engine

I've never seen a crank like that in my life, nothing more than a paperweight now.

At least ive still got some decencent bit, so not a total loss,

Yeh ive been keeping my eyes out for another anyway

Before you spend any money, take the block to a machine shop and get the bores measured properly and the head gasket faces checked for flatness. Going by the state of the crank, the engine had a hard life. So the bores may already be badly worn and require a rebore and new pistons etc.

EDIT: All the fastest engines are black

Did you take the flywheel off the engine or was it already off?

That really is something!!

Contact Fastcarl on here.

I recon that crank can be repaired but you will lose the cut out for the c washer.

Worth a go if its the only crank you have.

Si

I drill holes in everything..!

Is this another one of those 'i poured sand into the inlet to port my engine' type, joke threads?

I'd say, use it. JB weld first as above.

In the 13's at last!.. Just

If the bores are fine and the rings were sealing. There is absolutely no need to replace the rings. In fact, if the current ones are sealing on a factory hone etc, it would be best to leave them as is.

Although that crank is well screwed. It's all good and well cutting off a flywheel that is siezed on, but any idiot knows not to cut the bloody crankshaft itself !!!

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Was that in miniworld back in 2001

Can you see 0.010" of wear in the bores?

The rings in our van looked fine, but it still smoked like a bugger.

The Bores are spot on TBH

I think i'm gonna replace the rings anyway, just to be on the safe side

This has got to be a joke, I can't see how anyone could possibly think that crank is usable!
