I recently had the head gasket on my EF replaced, when in the shop i went to see it without the head

when i looked at the pistons they had engine coolant all over them!

i was told this would clean the piston.

is this true?

I wouldn't think so. When the engine is running, if you spray water into the inlet it will clean out the carbon deposits, sort of like steam cleaning, but just sitting there, I don't think it will do anything. When you take the head off, you nearly always spill coolant from the head into the cylinders. I always mop it up straight away, but I don't think it will do any harm in small amounts.

Doubt it mate.
However if it's not left there more than a few days it'll be OK.

I tend to think they are having a lend of you. More than likely, they removed the head w/o draining all of the coolant (easy to do) and as you turned up, they had to have an excuse . I would check their work VERY carefully. Ask them how they did the head bolts. (tension then 90 degrees) What sort of head bolts they used (AU ones are all the go now) Did they put sealant at the front of the gasket where it runs around the camchain housing?

As long as they don't try to start the car with all the coolant over the pistons it should be o.k.
