Combines Engine problems on my 4w305

[acre_eater]

I would replace them all if it were mine alot of the cost will be labor and you will spend most of it getting to one piston I wouldn't think it would cost a whole lot more to do them all once you are in there. By the way of all the tractors we have had around I think I miss our 4W305 the most. Tim

Granted a 670T is a different engine than the 6120T but to when in an engine, it is going to cost for a complete gasket set and normally they like to sell the sleeves as a set of 6 too or a complete OH kit is sometimes cheaper than individual parts for fixing one or two cylinders. That is a good long life engine you have but while it is open, I would go all the way. I did that with my 8030 and it was cheaper for a complete OH than just 2 cylinders fixed.
