Water in the oil. Pan will come off this weekend so not sure yet but looking like a liner issue.

M923 engine replacement options? Searched the site and couldn't find the discussion that I was looking for, so here goes. If you had to, or wanted to replace an Nhc 250 what would be your choice and why? I am looking for all the pro's and con's, cost, fitment issues, etc, of the available...

The fan definitly wasn't the cause of my issue, it was working properly.

Thanks Texas! That is a great suggestion on where to start. My thinker is not working well at the moment.

Any suggestions on where to begin looking.

As far as I know, mine was never rebuilt. Showed 29,000 miles on odometer when I got it. I know this doesnt mean squat, but it has always ran great before today.

Went to take the girls for the once a month spin down to the ice cream store. Pre flight checks were good. About three miles down the road I notice the temp gage at a little over 200 deg. This truck has never ran that hot before. Another half mile or so and it's at 210. I plan for a landing...

Do a search for haldex air dryer. There are guys selling the new models complete on here almost as cheap as the service kit for yours.

Welcome from Stanwood. Where are you at in WA.

Congrats on the truck, looks sweet. Next question is whats else is on the list, can't have just one.

The owner is trying to trade for construction labor, time availibility and distance prevent me from offering him that. What would be a fair price for something like this?

Ndt, thanks for the quick answer, now I can sleep tonight without feeling like I missed out on the correct one.

I admit it, I dont know squat about the smaller trailers. Stumbled upon this in a barter page. Would it be the correct vintage and size to put behind a 1974 m151a2?

Welcome from an hour or so south of the border!

Welcome from Washington. Just got my first 151 a few weeks ago.

Thanks for the tip. None of the bolts I removed showed any signs of a short threaded hole, but easy enough to check now. I like the pressure washer idea, when I rolled the block over on the engine stand I did get a little slurry out of the passages. Kind of surprised the pressure washer didn't...

I am in the process of gathering parts as we speak. Poppop, I definitly appreciate your offer of help with the parts but so far I am finding what I need without troubling anybody. Somebody posted that they thought the exhaust valves stuck from sitting, I think that diagnosis was probably...

Engine pics Got the engine out, cam looks ok, cylinders still have crosshatch showing, no sludge build up. Found the two broken lifter heads in the oil pan. Pretty obvious that the center two cylinders haven't been firing in a while. I am thinking of just replacing the damaged parts and seeing...

In the process of pulling the engine now. the cam lobe with the broken lifter doesn't look bad shining a light down the lifter bore. We will know more once the engine is out.

I saw those but the rust on the bearing journals scared me a bit on that new one. When I was younger I used to do quite a bit of high performance gas engine stuff. A lot of the cam rules from that are stuck in my head. Keep lifters matched to the lobe they ran on, etc, etc. Just need to get over...
