That seems odd after a fresh in frame for all of that to happen. Unless you got the Waterloo treatment. Did they use a reman head or just stick the old one back on? How about the parts? OEM or some aftermarket outfit? WAS THE BLOCK MACHINED?

As far as your plan, you are just playing with fire. You will be back in the same position your are in now in short order. I asked Mr Hagg about this plan when at his shop, as this seems to be pretty common, just replace a piston and liner along with the head. These motors fail soon after, usually within a few months, if not sooner. Total in frame, machine the block and new head, he will not entertain the thought of what you are proposing on doing.

Just on a side note, Rawze had to head over to a concrete outfit to look at a truck. I tagged along... They had a Fitzgerald Detroit Series 60 motor on a stand in the shop. These guys bought a lot of Fitzgerald tractors for obvious reasons. Well, it seems that Fitzgerald has two motor options, one with a Detroit reman block and the other with aftermarket in house built by Fitzgerald motors.

Well, the in house aftermarket stuff was good for around 200,000 miles according to this shop we were visiting. The mechanic said these motors failed in various spots internally from the poor quality aftermarket parts, big name aftermarket parts supplier. They have enough of these trucks in their fleet to verify this. They have hundreds of these trucks. 200,000 miles was the magic number, they in frame these motors in their own shops, so I think they know what they are speaking of.

In other words, I wonder what was done to your motor?
