Question on piston rings....
Discussion
Be gentle with me, I know very little about engine internals 
Got this question from my mate today, who had been asked it by the person with the problem. He knows I spend far too long on car BBSs which is probably why I was sent the question! Anyway, here it is :
Do you know of anything you can pour into a car's cylinders to ungum the
piston rings?
Don't know what car it's for, which is really helpful I know
Don't think it's anything special though, so no V6, V8, straight 6, etc. Just a bog standard inline 4 as far as I know in a general car.
Cheers knowledgable folk

Thanks for the info guys 
Engine is still in the car, it's a Peugeot 106 and has done 120k miles. Don't believe any compression test has been done, but that has been suggested by my mate to him, and is more enforced given that you guys that know about engines have also suggested it
Apparantly it was black smoking a lot and the garage looked at it and said it would cost about £800 to fix, but didn't say what the problem might be.
My mate didn't know if would be worth spending a tenner on some magic potion that might clean it up a bit if flushed through.

Another update, this time with useful information
Cut and pasted from my mate's email that he just sent :

It is actually worse than I thought. Mike wrote down what the garage said yesterday for me to read.
It is actually broken piston rings and loss of compression between cylinders 2 and 3.
£1000 for a reconned engine.
New car time I think.

Could get a second hand one from a scrappy, but I think he'll just get something newer (and not French ) instead.
Thanks guys.

Would put a new engine in from a scrappy anyway, can't be that much? Obviously depends on the age of the car.
Flog the car then get something new (TIP, make sure you update the V5!!)
