im starting to get parts together to build a 2L t4 for my bus....

ive got a set of original pistons and barrels, used and one piston has hit a valve so is rubbish but...

Should i get these barrels honed and trued (rebored) and a new set of oversize pistons, or just get a new set of pistons and barrels?

what are cofap piston and barrel sets like?

thanks
Edward

I re-used my barrels and oversize pistons on my 2L. Still going strong after a few years. Can't say there's much of a saving over a full new set though.
I think Cofap is after market Brazillian. Not sure on quality as I have never used them, but they make a lot of VW parts.

I can highly recommend getting the heads and pistons crowns ceramic coated if the budget allows. Helps save the heads which can suffer from, well what happened to yours 🙂

If you get new pistons and cylinders can i buy the old cylinders off you? only if they are original vw and no fins missing.

what he said then flog off the old ones to Damo ,, there's not a lot of point in stuffing around with old barrels unless you are geared up to do so
