leaking water from the cylinder block

[mailking]

Check the radiator overflow tank for bubbling from the overflow tube when the engine is hot and running - if you've got bubbling then you have a head crack or HG failure.

Or, park the truck on a steep downhill while hot and running - if fluid starts to pour out of the overflow, you have a head crack or HG failure.

Oh, I didn't read it correct. I parked the truc on a slant, ran it up to temperature and I saw bubbling inside the overflow bottle. I didn't wait until it was pouring out of the bottle.

wat does that read?

Just came from some lovely guys over at IVECO. They will let me work on the car myself and I can stay at the workshop overnight! They also called to Buenos Aires to inform if they could get some parts for the 3B engine. It turnes out they can! It might not be original Toyota, but at least I have something. They can get the whole gasket kit for the complete engine, and even a complete head with the valves.

How are your experiences with non Toyota heads? Apart from that it isn't original.

It is availible to me. Otherwise it would have to be shipped from Japan (60) days and will be taxed with 100%!

The only difference between the two tests I suggested is that if you're on a steep enough slope, the bubbles often get trapped in the back of the engine and force fluid out instead of gas. In either case, if ANYTHING comes consistently out of the overflow (other than the usual fluid exchange as the truck warms up) it means something else is entering to loop to push it out... like combustion gas.

(Do note that some exchange of fluid, and maybe a little gas if you had some trapped in there, is normal as the truck comes up to operating temperature and pressure. If there is bubbling once the temperature has stabilized, however, thats not good news.)

How much bubbling did you observe? I had a HG fail that started out giving me maybe one pea-sized bubble per second. Within a week it was bubbling like a kid blowing into his glass of milk.

There are a lot of people running aftermarket 3B heads. I don't know the specifics, but some of them are a "high nickel" variety that are said to be better at resisting cracking than the original ones.

Roodogs has 3B heads for 700 US on ebay, he ships internationally.

WHATEVER YOU DO, USE AN OEM HEAD GASKET.

^^ seriously. I replaced mine with an aftermarket job (see: https://forum.ih8mud.com/diesel-tec...at-hell-wrong-now-head-gasket-head-crack.html) and it started leaking within 6 months. The new OEM gaskets are an updated "MLS" style gasket that is far, far, superior.

I did see one pea-sized bubbel per second coming from the end of the tube that goes in the overflow bottle.

Hmmm, shipping from the US would also result in a 100% tax, and the guys here in Buenos Aires can get me a head with valves for 850 US aprox. [Do they always come with valves?]

Few things are certain:
- the engine is consuming water
- I am flying for 3 weeks to the Netherlands
- I can use the IVECO workshop and tools
- I can get non OEM parts in Argentina

So I have some things to consider here. I would like to take off the head before I fly to the Netherlands, so to see what is broken, and what I could bring back from Europe.

Once I have the head off, I would like to post some images in this thread for you all to see here. I would like some quick assessments as I have limited time before I fly. This would be a week before the end of the month.

Hmm, sounds familiar.

Does it help any if the parts come from australia? (roodogs in an aussie company)

[Do they always come with valves?]

Nope, valves with the roodogs head would be $75 more, i think. Sounds like what you found may be a good price.

Before you do ANYTHING, be super-sure the head is the culprit. The bubbling, the coolant loss, and the overheating suggest it might be, however the leak down the side of your block would be a pretty rare symptom (but I suppose not impossible) symptom for a head problem. I'd just hate for you to pull the head all because you just had a bad freeze plug.

Some other things I noticed when I needed a new HG - the coolant bottle would overflow when I was running long and hard. I would never see it, of course, but when stopping after a good hill climb or long highway run I'd see moisture on the fender below it.

Assuming you're confident the head is the problem, I'd get it pulled ASAP and have it magnafluxed and/or pressure tested before you leave. That'll tell you if you need to order a new head and have it waiting for you when you return. If the head is good, set it up with a new gasket and precups and be done with it. Otherwise, get a new head, valves, etc.

Plan on replacing the precups no matter what. Since your engine has been doing hard work, you can be sure they're cracked - while cracks are common, they also lead to devastating consequences from time to time (https://forum.ih8mud.com/diesel-tech-24-volts-systems/194124-dont-loose-precup-3b-carnage.html). The cheapest I've found for a set of 4 is $99.

Hmmmm... Dunno what happened. But I was halfway, all cables and tubes gone. Took the injectors out and I had my tools on the bolts to loosen the head. While some little voice inside told me to look once more at the radiator. I decided to take out the radiator and had it tested. We saw two leaks in the bottom part, that were behind the protective stone wall.... Duh... Today and tomorrow wel test drive and head out to meet the WRC in the Cordobese hills... That should point out if this is fixed or I need to return once again to my toolshed... thanks for staying with me on this..
