My experience is that if you go on the tight side, the engine will never rev well, it will feel tight. If you ahve them leave it on the loose side, it will rev freely, won't feel "not broken in" or like a cold motor all the time..
You really need to send the pistons to the shop, if they are good at what they do, chances are, they will get it right. This is not exact science... It's preference more than anything.
OK, thank you. Block is at a good shop, they'll get it right. I'll be in touch.
Mike, I have my 1.6 TD open now for valves and rings. It really needs to be bored but I need the car soon. I ran a ball hone through it tonight to prepare for new rings. The pistons are 76.48 mm. They have been in carb cleaner for three days and have cleaned up real nice. The old rings were basically oil crudded into the lands. There is about .005 inch wear on the bore which I realise is out of spec but this will get through the winter while I work on my Landcruiser. What oversize would you go with? Most shops always seem to want to take a fresh cut at things which usually means two oversizes. How do I order with Paypal? Haven't done it recently.
