International 574 Part 2

This is the second part of our rebuild on a 1973 Case International Harvester 574 tractor. in this video we are removing the valve cover and head to see the pistons. We suspect that we have diesel fuel in the oil and that has been our issue, possibly a blown head gasket? We will attempt to find out in this part 2 of the rebuild series.
Back Story - I purchased this tractor several years back and it had issues when I purchased. We ran it for a year on our farm and then started the tear down process and it ended up sitting for over a year torn down. This is, hopefully, our rebuild of the tractor to restore it to use and in general restoration of the tractor. Please follow along with us on the rebuild.

If it is Diesel fuel in the oil it is usually a leaking seal on the front of the injection pump drive shaft. Easily replaced but the pump has to come off.

Yea it ended up being a blown head gasket so we went through head and had it worked by a local machine shop.

U mnie w 574 wyrzuca płyn chłodniczy przez chwilkę w momencie gdy z wysokich obrotów zejdą na wolne, na przykład gdy jadę i dojeżdżam do końca pola chcę nakręcić puszczam gaz i wtedy płyn wyrzuci przez korek od chłodnicy, a test na uszczelkę pod głowicą pokazuje że to nie jest uszczelka, co może być przyczyną?

I would try replacing the radiator cap first this would be the cheapest and easiest way first to see if that is the problem.

Check your injection pump if you have diesel in your oil. Had the o-ring give up the injector drive on a MF and it caused the engine to run away. Got it shut down before it blew.

We will sure do it, thank you for the heads up!

[@colmanlong1032]

Be interesting what is actually causing that stuff.

[@greenecreekfarms]

We are ready to find out for sure!

1 or 2 of your liners are leaking, the O rings went bad or they rotted through

[@greenecreekfarms]

Yes Sir. We found that about 2 were leaking when we disassembled. We sent the head to a local machine shop and they re-worked it and it looks great now. Hopefully reassembly will go smooth also. Lol
