1610 head gasket issue

[kenmac]

atleast you'll know it's not a stuck valve /cracked head causing your over heat / loss water problem. I Hope you have solved your problem

Thanks Kenmac....

I got the head back on the engine today and have run it for about 2 hours total since it was installed. So far no puking of water out of the overflow bottle like before, but I am still seeing air bubbles in the radiator while the engine is running. So I am not sure I have fixed anything with all the work I have done and money I have spent. The engine seems to be running fine, it started right up on the second start attempt and sounds good. At least that is going my way.

I ran it for about a half hour after I first got started. Then shut it down and let cool and rechecked the torque on the head bolts and double checked the valve settings. All where as they should be so I think I am good to go for now. I am going to try and put the tractor under a load for several hours tomorrow if weather permits by doing some brush hogging. If it makes it though the day with out any of the old issues I call this a win

I am starting to wonder if there is some way that pressurized air can enter the system that I have not tought of. Since this only happens while the engine is running and stops as soon as you shut it down I was convinced it was compression leaking into the coolant jacket of the engine. Now I'm not so sure. I know the head is good becuase I had it checked so that would only leave the block as a possible source right? This engine runs and starts way to good I think to have a issue with the block, but I could be wrong. Once I am sure the headgasket replacement was a sucess (no mixing of fluids after several hours of hard work) I will recheck the compression on each cylinder just to see if there is any leakage.

Oh yeah something else that happened today that I tought I might should share with everyone. The #3 injector fuel banjo bolt snapped off while I was reinstalling it. That cost me a few hours of pain and heartache. It appeared to be a homemade one after I got to looking at it. Or at least it was not identical to the other 2. So since I could not buy one any where around here, I went to the autoparts store and bought an 8mm by 1.25 grade 5 bolt and made my own. It was not very hard and it has worked good so far. I will order an OEM one next week to replace this one but if anyone has the happen to them it is easy enough to make one to get you by.

Keeping my fingers crossed for now for no rain tomorrow so I can test my work.

I hope the head solves your problem. The only palce to go is down & I mean the block. Is there a coolant hose comming off the block somewhere that returns to the radiator ?

Box, if you have any suspicion of a coolant/compression leak be sure to crank it over with the compression released to clear any water out of the cylinder, before actually starting it.

Off subject. Cal, Did you find out what happened to norm ??

No. I see he is continuing to post elsewhere so he seems to be ok, but that's all I know. Norm, come home! At least send a PM!

Excellent point!

Hello all,

Thanks for your input on this.

Kemac - yes there is a drain line that runs from the engine block to a block that ties into a drain for the radiator. I had not tought about that being a possible source of the compression leak back into the radiator, but your post has me thinking. I could plug off the hose that ties the drain line from the radiator to this block and see if it makes any difference.

California - I don't think any water is entering one of the cylinders. I ran the tractor today from 8:30 am to noon or so brush hogging abut 2.5 ac of 1' tall grass. The engine runs great and has power. The coolant temp gauge stayed at or beow the 1/2 way mark the whole time and even tough I could see bubbles entering the over flow bottle the bottle never over flowed as it was doing before I tore the engine down. So what I have done seems to have made a postive differnce in the performance of the tractor.

I took the advice of Sandfarmer (I think it was) and only filled the over flow bottle to the low mark and that seemed to prevent the bottle from over filling. As I stated before I am a bit baffeled by the air bubbles that I see in the cooling system, but I am begining to think that the real issue may be that the coolant system does not allow enough room for expansion. On the larger diesel engines we service at work we always allow 15% for expansion. Granted these are a lot larger (15 to 60 liter ) engines but the rules of thumb should be more or less the same.

So for now I am going to monitor the engine when ever I use the tractor and see if anything changes. I still have no mixing of fluids, oil in water or water in oil and other than the air bubbles I mentioned before everything seems to be in order. That is way I am so baffeled. If the engine was running hot, had problems starting or seemed to be low on power I would be more concerned than I am. I plan to do a compression test on the engine as soon as we get moved into our new home. Right now I keep the tractor at my new place so I only work it on the weekends for the most part.

I will keep puzzeling over this in mean while.

Thanks for your input

How do you know he's posting some where ?? Do you mean another forum ?? I haven't seen him post on any topics on this forum

Box, I didn't know if all tractors had this coolant line or not that's why I asked. I know my 3110 does.
