Re: 590E engine head problems

For pics see this: https://www.fordsontractorpages.nl/phpbb3/viewtopic.php?f=1&t=5024&p=53955#p53955 Sounds like you'll need new liners, make sure you get the right ones (only two available, but one of them will certainly fit, they are as Shepp pointed out spigoted ones only).

Re: 590E engine head problems

shepp, thanks for your post. At the moment my conclusion is that liner 4 has almost certain cracks. I did the dye test for a second time with great carefulness and even more protentional cracks show up. I showed the pictures from the liner to some mechanics and guys from quality department who do dy...

... Castrol NF and SF that have ingredients designed to reduce cavitation to protect the wet liners - they are not suitable for older engines like the 590E and 592E however. If you fit new liners be sure to shim them correctly to give the correct protrusion as per the workshop manual, I think all liners ...

Re: 590E engine head problems

Sandy thanks for your answer. I seems the valve stem diameter of 9,5 mm is pretty standard, as my engine shop had a pilot for this diameter. So they might can get valve stem caps who fit. Yesterday I did some dye check after cleaning the head and in 4 of the 6 cylinders. After applying the red dye, ...

Re: 590E engine head problems

Unfortunately they seem to be very difficult to find, at one stage I thought CNH had some but we've never got round to finding that out yet. Other than that there are no new ones around.

Re: 590E engine head problems

Forgot to ask a question :oops:

Anyone knows if the small cups which are on top of the valves are still available? (those where the rockers push at) These are different on the intake and exhaust valves. The ones in my engine are pitted and should be replaced.

Re: 590E engine head problems

thanks for your reply mister shepp. There is no sign of water in the oil, but all fluids were new so maybe the water had not enough time to migrate into the oil after 30 mins running.

Re: 590E engine head problems

It's a fairly robust head with enough metal between cylinders and across the valve seats, and cracking is not known to be an issue but that doesn't mean it cannot happen. Having said that I did once have a D series horsebox in the late 1960's with the later 330 engine and that developed an invisible...

Hi Mathias, I wonder if they can get the head tight for pressure test without resurfacing, but I let the company do that. Still have to scrape the gasket surfaces. The 6D and 4D engine parts are the same, just 2 cylinders more, besides of the oil pump which has higher capacity because of the extra b...

Re: 590E engine head problems

Today I inspected the head. Till now, no cracks found. I noticed that the valve stems of the exhaust valves are pretty worn (9,43 mm instead of 9,49 / 9,50). The carbon has an abrasive effect. The intake valve stems are very little worn (9,47-9,50 in diameter). I decided to replace all valves and v...

Re: 590E engine head problems

Head failures are generally from incorrect coolant (corrosion and freezing, not common but very possible), I would suspect insufficient head torque or liner protrusion first, the valves are less likely to be related. If not then look for a crack in the head or the liner (although it's rare in the li...

Re: 590E engine head problems

If you don’t find evidence of leakage on the head gasket and you’re sure it was combustion gas causing bubbles I’d start looking for a crack in the head. Pressure testing the head is an option to find any issues. An engine shop should be able to support you if you can’t find anything yourself. Posti...

Re: 590E engine head problems

First find yourself a gasket set for the engine. It will have all the seals you need. Like these: http://www.jmgaskets-seals.co.uk/proddetail.asp?prod=DGD600D&cat=324 It does have the same valve stem seals as the Fordson engine. Look if the valves are usable (not bent) and see how much play there is...
