Dale Hamilton Posted September 23, 2005 Share Posted September 23, 2005 water gushing from between the heads of a ENDT 673. I sent it to the Mack dealer because the whole top of the engine had to be pulled. Sure enough, there at the butt ends of each head was a freeze plug, Damn damn. Naturally I had both plugs replaced and a new head gasket- but this is going to cost big money.

Rob Posted September 23, 2005 Share Posted September 23, 2005 Dale, it's not that big of job to change heads or gaskets in that engine. I can have one apart, and cleaned up ready to put together in 2 manhours after the fluids are drained. Of course I did that four times on my "yellow dog" project last year, and experience is a great teacher. Air tools help trememdously also. I built a jig for pulling the heads (straight out of a service manual) and use the "cherry picker" to hold the weight. You're right; the cost will be high for this type of work.

Dale Hamilton Posted September 23, 2005 Author Share Posted September 23, 2005 Rob- right most B's. But this B has alot of stuff added which must come off- AC,PS, etc. Then too its a studded head which has not been pulled in many ,many years. I have air tool- but the possibility of stripping a headbolt is pretty high. I didn't want to, but in the end I thought the dealer would be better.
