In what way has engine blown?
the local engineer has replaced the head gasket but doesn't think it will last long, on the slurry tower pump this winter. he says the block needs skimming , and reboring and oversized liners. He is expensive , I am capable of removing an engine from a tractor and replacing it, so wondered about putting in another engine.

Was the head skimmed?
Driving slurry pump is hard work
Is cooling system in good order ?

My father had a 1969 G reg 165 new and I’m sure the exhaust was on the lhs and I thought it said 4.212 on the air intake manifold (But might be wrong). Could it have been a 4.203 if the exhaust was on the left?

Nearly all the 4.236’s I’ve ever had (175, 675, Manitou MB25P) were a bugger to start when it was cold. Yet that 165 and a 690 with the 4.248 were alway good starters, no matter how cold it got!
203 definitely has exhaust on the left and is smooth as silk
212 sounds rougher than a badgers backside
 
Driving a slurry pump is NOT hard work, but pumping slurry into a above ground store is a sure way to wreck an engine
Would pumping slurry wreck an engine only if it was not maintained properly which includes
Cooling system
Also does modern low sulphur diesel in older tractors cause problems
Since yesterday I remember a now retired contractor telling me when he worked on a farm 3 miles away in the 60's he was the sole driver of a new
165 doing 1000 hours a year and it was traded in at 6000 hours without any problems at all

Thanks, it must have been the 203 then. Was definitely smooth as silk and a good starter when cold.
Eventually, the rings went and she started burning oil. If she idled a long time, then you reved the guts out of it, it would blow a lot of unburned oil out of the exhaust, sometimes even a flame a couple of feet long too!
In fact, when the starter got hot and wouldn’t work, this tractor often got left running in the field where it was loading trailers with a flat 8. After lunch one day in 1976, it blew than many sparks out of the exhaust that it set fire to the stubble field it was in!
Eventually, we fitted a new starter and replaced the pistons and ring and she was as good as gold again.

As an aside sorry while ur talking engine re build.
Chatting yesterday, mates saying if a head is skimmed , u put a punch mark on head gasket as it needs a thicker gasket to compensate for metal removed ,in skimming ....... is this true

What matters is the protrusion of the liner above the block face. I don't think that skimming the head is as critical as the skimming of the block.

Trouble is it's maybe 10 minutes work at a time, cold engine, high revs for a short time is not good

got a 65 with a 203 in it and indeed it is smooth and starts and pulls well
use to have a 50B with a 212 and that ran smooth enough, wasn't quite as good to start but pulled well
the 290 I use to drive limespreading with a 248 in was a right bitch to start but once going it pulled bloody well and ran nice enough
Our 565 with a 236 in it wasn't great to start till the starter went and we fitted a new one now its ok, new starter must turn a bit faster, it pulls well but has had the injectors changed and the pump opened up to make it the same as a 575

I had a 690 (428) which was a wonderful tractor as long as the cab never saw any water.
It pulled well above what was supposed to. Never had any problems starting it though. Whereas my 675 and 175 with the 236 were both bad starters.

If I could find a nice 690 with doors that hadn’t got Metal worm, I’d buy it for sure.

Its odd we had a 590 with a 248 and that started fine
We had a 690 turbo that started well and pulled like hell but the 698T we had after was better even though it had the smaller 236T engine in it
 
Trouble is it's maybe 10 minutes work at a time, cold engine, high revs for a short time is not good
I don't do any heavy work with tractor now but when I did I always let engine warm up first and when finished I shut it down for a few minutes before stopping
Also it is my opinion that really thick dirt on engine will act as insulation stopping a certain amount of heat getting out

I've never heard it before either. Mate , ex mate , being a clever bugger that I didn't know ..........
I can see the logic but sounds b\ s

Haven't heard of it with Perkins,but Zetor used to supply thicker head gaskets if needed. I had a 7045 that I'd had the heads off. Didn't think much about the gaskets and refitted standard new ones. Started engine and knock,knock,knock, albeit only slight but noticable. Heads of again and gaskets studied.Sure enough there was a considerable difference in thickness.Said to the Zetor dealer and he said that if the heads were skimmed enough before, thicker gaskets were required which he was able to supply off the shelf.

Zetor like a lot of other tractors had wet liners, the reason for different head gasket thickness was to compensate for the liner protrution above the block face. You fitted the liner and piston then with DTI find absolute TDC then use the DTI to measure the distance from top of block to top of liner and to double check that the liner was actually higher than the piston at TDC. If not then you would need to shim the liner. You then compared liner protrusion measurements with workshop nanual spec to tell you which of three different gaskets to fit. The beauty with Zetor, Same, Lamborghini, Hurlimann etc was single heads for each cylinder so each cylinder coukd be matched up with correct gasket.
