Took the heads off the car today to be greated by these. Is this normal for pistons to look like this

Only if your car is fooked

I have saucepans that look like that (but quite a bit larger)

looks like its been burning a bit of oil but them swirls are normal,is the way the air and fuel mix enters the cylinder

Cheers gents

I had hoped the oracle of knowledge (Gary) would be around

Cheers Gary.

We plan to clean them up and fit new piston rings is there anything that we should look for or are we better off fitting new pistons.

i was going to say, the cylinders in the mini were like that and they were okay

fitting oversize pistons will always be best ,but may be get a engine company to measure bores to make sure they dont gone oval

if they ok then a hone of bores and replacement rings

Once we get them out i'll check the bores for roundness. That's something i can do

If all is ok we'll go from there, we have 3 options to look at but at the moment it may come down to cost. Due to work situation.
