Mack Ai-427 Aset


Recommended Posts

What about this engine? Right now when I start out in 1st, it puts out a pretty good amount of dark smoke, but after that, its all clear. Ive changed the air filter and fuel filters, but not much changed. What about adjusting the valves? I dont know if they have been adjusted yet? It has 176,000 miles. What should I be doing for this engine? Are there any secrets or problems with this motor?
