Damn good info

Back to the Magnum engines. I now have several 5.9 running engines in various vechicals. A couple of weeks ago I bought another complete 2000 ram 1500 4x4 for $500. Have not decided to part it or drive it yet. I have bought trucks and Durango with the 5.9s for $100 to $1200. You can get the rusty rams with a bad transmission for $350 to $600 al day long and the one with a bad motor are even cheaper.

So far none of the magnum heads I have removed have been cracked. So is the cracked heads a problem with engines that have overheated more so than anything else?

The head cracking issue is overrated and blown out of proportion. I’ve been saying this for a long time. But everyone I meet, total strangers mostly, that see’s my 5.9 in my ‘79 start out by saying… “Your heads are cracked, what are you going to do about it?”

I just laugh and say “Not a damn thing! It runs fine and IF there cracked, I’m not worried about it.” I try an explain things and there one track mine takes over and it’s usually coupled with the I-d-10-T virus where there volume dial gets stuck and there ears close and they proceed to talk over me loudly coupled with statements of I have no idea what I’m talking about.


Ummmmm, yeaaaaaa, ummm, OK THEN!

The cracks are between the valves WHEN THEY OCCUR and there nominal is depth most times. If and when the crack appears, if it travels into the valve seat area, then you have a problem. And your engine still runs.

To answer the next question that pops up… no I would not out cracked heads on a engine. Yes, I get asked that and I can’t believe that I do but it happens.
