  1. White smoke is normal on start up on the VMAC 1's and 2's as the timing advance is powered by oil pressure and of course when you first start engine it takes alittle while to get the timing advance moving. On the black smoke, everything on the turbo boost side. After cooler, intake manifold gaskets, dirty air filter. Black smoke is unburnt fuel, Either from to much fuel or lack of air/boost.

  2. Hey mackpro do you think it would be wise for him to also check fuel lines and make sure they are tight cause i have a 95 ch613 when i bought it it was having trouble starting like MTR is having the fuel system bled off after a couple hours and in the mornings it was a pain till i had enough and every connection i check and all cooper washers and i found a washer had a slight blemish changed it that cuired the problem cause i was talking to a company about fuel pump and associated items and i was looking at almost $6000 and come to find out a $1.50 washer was the problem

    His truck is a ETECH style engine with no real injection pump but I know the copper washers you talk of on the older injection pumps, they now have a steel washer to take its place.
  3. driver says it seems to run fine but idle has me concerned. would supply pump affect idle also can supply pump allow fuel to back down (checkvalve)

    The check valve could be bad, its on the pass side of the block above the air compressor. The idle issues is probably that the driver hit the cruise buttons just right and lowered the idle speed, it happens alot, I always turn this feature off in the parameters to keep this from happening.
  4. I vote turn signal switch as well. I hope your style is not the kind that you have to remove the steering wheel to change the turn signal switch. I really liked the days of the old flat dash CH's where you could change the TS switch in under a minute with the right size torx screwdriver.

  5. Not a single warranty claim in it's life which could be good or bad. Seems like a good all Mack truck with T-2180B trans and Mack rears with 3.86 gears and air ride, It came with a 64" mid-rise sleeper. Engine has Jacobs engine brake. If the cam had been replaced and the Jake pins replaced I would not be scared to jump in it and go cross country.

  6. We lost alot of customers in 2004 when they bought CX's and CH's with the AC engines. Had to change the fan belts at every oil change (due to under hood heat damage), EGR cooler failures, turbos every 80-100K miles, fan hub failures. It was bad. Afew of the customers traded them in for CV's with the AI engine set up as daycab road tractors, alot less issuses but poor MPG. The CHN's and CXN's with AC engines came out ayear later much improved and things got better as turbos, fan hubs, belts and tensioners were improved/updated. But that bad 2004 year cost us dearly here!

  7. We have had two home invasions within 25 miles of my house where the victims open fired on the bad guys. We actually have a low crime rate around here with only maybe 1 murder a year. I have had my CCW permit for almost 15 years, I never leave home with out it!

  8. Pull down the metal kick panel in front of the passenger seat below the fuse panel. Behind this panel you will find the ABS ECM and the VECU ECM. The ABS ECM will say WABCO or Bendix or some other ABS system maker . What you want to look for is the Mack VECU ECM. Its a thin black plastic rectangular ECM . It has 3 push in wire connectors but places for four. First thing to check is see if the VECU ECM is faceing up where the connectors come in from the top. If so thats a bad sign, water seems to so how get into the ECM when facing up. Regardless unplug all 3 connectors and check for green or damaged pins. If all OK and the ECM is faceing up , unbolt it and turn it faceing down and reconnect all plugins. Next is to try to catch it "not starting" and check to make sure all 4 power relays (next to fuse panel) are powering up. I think #3 power relay fires up the engine ECM. If this relay fails all will seem to work but crank no start and this failure will not set a code.

  9. I hear that they are having some paint problems over at Mack, any truth to that or just rumors? I do know that one of my Concrete customers had some paint prob. and Mack took care of them. The trucks by the way are running great an the drivers love em!!

    BULLHUSK

    Yes on the paint problems. We are having issues with trucks that are ordered with a custom color. The hood and cab come out 2 different shades/colors.
  10. The problem we are seeing with Mack building so many trucks is that all the parts are going to the factory and the PDC's (parts distubrution centers) dont have the parts we need to fix the older MP engines. Here lately we have had to get parts pulled off the assembly line to fix the trucks we have broke down. While we can always get these parts it takes an extra day to get them to us. Other that that keep on building!

  11. The GR pipe at the turbo was a $130 or so pipe including the pyro inlet. It wasn't listed for the Granite but it slid right in. I will post parts when I get truck back.

    We used a Walker muffler $70, that was 5 in and 5 out. Two problems here were.... Need a new heat shield $170, stainless, because the new muffler is 10". We neded to get 2 extra heat shield bands to secure the new muffler (10") to the side of the cab in existing factory mounts. Bands will need slight fabrication to make work. I have about $700 in parts for the exhaust system.

    You dont know the part# of that Grand Rock pipe or know what model it was for ? Thanks
  12. Boost in mountains great

    Engine brake double what it was

    Mpg up 2/10 but I drove 8 mph faster and was fighting a 20 to 40 mph head wind

    Quiet and smooth, power great

    No leaks check every day

    As all ways great service

    We need to work on finding a better muffler. Found some flow charts on some different brand under cab mufflers. I think it would help some.
  13. I am the Warranty Admin at our Mack dealership, always read the fine print on the Mack warranty , the salesmen will tell you anything to sell a truck. Most everything inside the cab (except certian AC parts by Berh) has a one year warranty its been that way for 10-15 years on Mack. As far as the steering column goes, we have had the same thing happen on several trucks but never changed out the whole column, A cable kit/ gas cylinder usually cures it. Thank Volvo for that crappy design, it came from their trucks along with that air assist clutch crap!
