Joey Mack Posted May 10, 2023 Share Posted May 10, 2023 You need to pull it and check it and a pop test if there is nothing obvious.. if you wash a cylinder, your done..... That will have to be repaired, and a lot goes in to doing only 1 cylinder.. Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted May 10, 2023 Author Share Posted May 10, 2023 (edited) I'll give that a shot next, there's no smoke at all so I wouldn't think it would be a Cracked or failed nozzle. Here's that video if it's any help https://youtube.com/shorts/fkKcnWAUbiw?feature=share Edited May 10, 2023 by Dalton1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 10, 2023 Share Posted May 10, 2023 The fuel spray looks good, (by my eye).. has the oil level been rising? Anyway... Pull the nozzle... Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted May 10, 2023 Author Share Posted May 10, 2023 Oil level doesn't seem to be rising but it hasn't run much either, just a few minutes. I'll pull the nozzle in the morning. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 10, 2023 Share Posted May 10, 2023 Are you doing all the work? Or do you have a local shop? I have been out of Maine for 17 years, and don't know who fixes Macks anymore.. Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted May 10, 2023 Author Share Posted May 10, 2023 I'm doing the work myself, I usually do everything but this one is challenging me. There's just O'Connors in Portland but from what I understand the don't do much with the old mack engines like mine anymore. I don't know anyone local that works on them.

Joey Mack Posted May 11, 2023 Share Posted May 11, 2023 No shit!! I started at Maine Mack there on Warren Ave. In 2000.. I was there when Dick O'Connor bought them.. there was 36 of us... Whenever the change happened they kept about 12.. me included. I left there in early 2006.. Too funny.. Jojo Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted May 11, 2023 Author Share Posted May 11, 2023 I wish you were still working there!! I just pulled the nozzle, visual looked ok, swapped it with #5 and the problem moved to #5 so I guess I got a bad nozzle, thought I'd get more than 40 miles out of it. 1 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted May 11, 2023 Share Posted May 11, 2023 You say they don't work on older Mack engines at OConnors.. when I was there, (before I Connors). we had a rebuild room, and in the parking lot was a separate building, it was a pump shop.. my how things have changed.. your Mack is not OLD to me, but today, I guess it is ancient...

Dalton1 Posted May 11, 2023 Author Share Posted May 11, 2023 It's not old to me either, newest truck I've ever owned, I bought because I wanted the newest truck I could get with a true Mack engine. They work on them but last time I was there they only had one guy that knew anything at all about the grey engines. I think the pump shop your talking about was converted to the Hino sales office unfortunately. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 11, 2023 Share Posted May 11, 2023 It is the sales office.. is the spring shop still across the street? I also wonder if anyone I worked with is still at Mack.. Specifically Earl Harnden... Quote Link to comment Share on other sites More sharing options...
Dalton1 Posted May 11, 2023 Author Share Posted May 11, 2023 McFarland spring is still across the street, they usually seem pretty busy. Doesn't sound familiar but I'll ask about him next time I'm up there. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 11, 2023 Share Posted May 11, 2023 Cool.. they made springs for my Toyota truck that I still have for 22 years now.. Earl was about 65 years old back then... I hope he is still alive. I really Hope his Legacy is still alive... He took me under his wing after a year of hating me, and he instilled a work ethic in me on how to fix Mack's, and build the engines.. Every time I build a Mack engine.... He is with me... ''What would Earl have me do?''... Jojo Quote Link to comment Share on other sites More sharing options...

The omaha mack dealer had its own pump rebuild shop years ago, but no more. terry Quote Link to comment Share on other sites More sharing options...
