Oh the old dropped valve chestnut........ well it may be an issue in his little world but not in mine. I've owned power star engines tractors for 17 years and not had the need to see inside one yet. Had to rebuild the engine on the '16' we had though. After the head gasket suffered from a nasty bout of Johndeereitus!

Just an unnecessary cost that comes with running old tractors like that I suppose. I'm just glad we've seen the light and moved on to more reliable, more modern and cheaper to run tractors.
I was always led to believe that dropped valves were due to drivers letting them run over downhill, so there driver error not manufacturing error

Not sure to be honest. I know it can happen but it's certainly not as common as some (well 1 person) make out. I Don't actually know of anyone personally who it's happened to and there's a lot of 40s, 60s and TMs still running round here on high hours.

odd, i recall you starting a thread on this very issue to gauge opinion......and there was quite a few people who came out and said they had had issues with them

for the OP....ring Mr McMurray up from Ireland, he will soon educate you as to how much a powerstar costs when it goes bang, he usually does at least one cylinder head a week.

Very true. But will stand by what i said above. Ive since spoken to several mechanics locally and have been assured it's a fairly rare occurrence. I can back this up with my own and other locals very satisfied ownership experiences of Powerstar engined tractors.

I've no reason to bulls**t if one of mine or another one i knew of had gone bang i would have said so. I don't know how many power stars were made but i reckon it's a lot so there is always going to be a percentage that let go due to abuse,faulty manufacturing or components or sheer bad luck.

Without being sarcastic i bet there is a much larger percentages of DB engines that have been rebuilt per hours worked than powerstars.

Probably much older and with higher hours on too................

after all....your comparing engines built from 1970s technology and materials, with those built from late 1990s technology and materials....

with all those advances, they shouldnt drop valves at all.....you would think

Well as you don't have one it's not something you need to worry about.

I will deal with it if it does.

Id frame it and hang it on your living room wall

what he puts on facebook is quite different....more than a few people send him heads to be done before they have even dropped a valve...peace of mind and all that
