  1. 454 HAS A EXTERNAL INJECTION PUMP MADE BY BOSCH. MY 460 ETECH HAS A INLINE PUMP. I'M GONNA TRY THAT, AS TO THE TURBO, I'M THINKING ON GETTING ONE FROM (RICHMOND) THE PERFORMANCE TURBO . THAT WILL BE DONE DOWN THE ROAD WHEN I MAKE SOME EXTRA CASH, THAT IS WHY I'M NOT CHANGING IT NOW. THAT'S A LOT OF GOOD INFO HERE. THANKS GUYS FOR ALL THE HELP. GREATLY APPRECIATED !!
  2. THANKS FOR REPLAY. WHY DO YOU THINK LINERS IS THE PROBLEM? PLEASE EXPLAIN ... THANKS, RAF.
  3. AS TITLE SAYS ON MY 97 CH613. I WAS WOUNDERING IF SOMEONE HARE CAN CONFIRM IF I'M RIGHT OR WRONG OR, IF THERE IS A OTHER SOLUTION TO THIS PROB THAT IS NOT TOO EXPENSIVE. WHEN TRUCK IS IDLE AT 600 FOR MORE THEN 5 MIN IT PUSHES ANTIFREEZE OUT TO TOP TANK THEN IT GOES TO THE OVERFLOW TANK AND FINALLY SHOOTS OUT THRU A SMALL HOLE IN PLASTIC CAP. WHEN I IDLE AT 1000 AND ABOVE OR JUST DRIVE IT, THEN I NEVER HAVE A PROBLEM WITH OVERHEATING NOR LOOSING ANTIFREEZE. I HAVE REPLACED A WATER COOLER, A TOP TANK CAP, TOOK A THERMOSTAT OUT, FLUSHED A SYSTEM AND CHECKED A RADIATOR FOR LEEKS. EVERYTHI
  4. YES, THEY ARE IN (F), AND THE SENSOR IS MOUNTED AFTER TURBO ABOUT 4-6 INCHES ON PIPE THAT GOES DOWN UNDER TRUCK. RAF.
  5. DO YOU KNOW IF I CAN USE IT ALSO ON E7-454? IT'S A 18 SPD MACK TRANS. I HAVE ANOTHER TRUCK THAT HAS OTHER PROBLEMS BUT THIS COULD BE AN IMPROVEMENT TO IT. IF NOT THEN I'LL ASK THEM ABOUT IT. THANKS, RAF.
  6. TRUCK WILL BE DONE TOMORROW I WILL POST RESULTS. AS TO THE PRESSURE, THEY HAVE CHECKED THE WHOLE SYSTEM AT 40PSI STARTING FROM TURBO SIDE. THERE WAS NO LEEKS... I'M ALSO HAVING A TIMING SENSOR TIMED AND ONE INJECTOR REPLACED, THEY HAVE FOND SOME PROBLEM WITH IT. I THINK THAT THIS WILL GET MY BOOST BACK UP TO NORMAL. I HAVE ALSO REPLACED AIR FILTER AND OIL COOLER. THANKS, RAF.
  7. I HAVE CHECKED A COMPUTER BEFORE AND NO CODES BUT ONE WHICH IS A ABS SENSOR THAT I HAVEN'T REPLACE IT YET. SOMEONE TOLD ME THAT I MIGHT BE A TIMING SENSOR NOT PROPERLY SET. I DON'T KNOW IF I SHOD DO THAT. MAN ALL THIS STUFF IS SA DAMN EXPENSIVE BUT WHEN I GOT NO POWER IT JUST PISSING ME OFF !!! TRUCK DOES LIKE 100MPH ON FLAT HEHE... BUT WHEN IT SEES A HILL, IT'S A TOTALLY DIFFERENT STORY ! SO FRUSTRATING!!! THANKS AGAIN, RAF.
  8. I HAD NO IDEA THAT POSSIBILITY OF UPGRADING THRU MACK EXISTS !! THANKS FOR THIS INFORMATION, I WILL DEFINITELY ASK ABOUT THAT. THIS FORUM IS GREAT !!! THANK YOU ALL FOR COMEBACK !!
  9. I'M ONLY GETTING SMOKE WHEN SHIFTING GEARS. MY FUEL PREASURE IS AT IDLE 80 AND RADDLE 90%. I HAVE CHECKED AT MACK SERVICE. THEY SAY, IT WAS NORMAL. MY PYRO WHEN PULLING FOR MORE THEN HOUR IS ABOUT 1200-1400 WHEN IT CLIMBS IS ABOUT 1600 THANKS, RAF
  10. HEHE, FOR SOME REASON I USED MY LANGUAGE YOU MIGHT BE RIGHT ABOUT AIR FILTER, I HAVE NOT TAUGHT ABOUT IT . TRUCK IS IN A SHOP NOW FOR VALVE ADJUSTMENT, AS FAR AS I KNOW, THERE IS NO MANIFOLD LEEKS. I'M GONNA ASK THEM ABOUT CHECKING COMPUTER FOR THROTTLE READINGS... THANKS MUCH FOR HELP .
  11. TURBO SHAFT HAS NO PLAY, I HAVE REPLACED ALL 4 RUBBER AND CLAMPS CONNECTING AIR HOSES. I THOUGHT THAT COMPUTER HAD NOTHING TO DO WITH IT SINCE EVERYTHING ELSE IS WORKING FINE. AS TO THE WIRE HARNESS, WITCH HARNESS ARE YOU TALKING ABOUT?... I WILL ALSO TRY TO RESET THE COMPUTER AND WILL POST HERE ANY CHANGES. THANKS FOR HELP.
  12. hello, THIS IS MY FIRST POST HERE, I JUST FOUND THIS FORUM AND IT'S A GRATE PLACE FOR INFORMATION AND HELP. I HAVE A 2000 MACK CX613 WITH A E7-460 AND FULLER 13-SPD. MY PROBLEM IS THAT I HAVE A LOW TURBO BUST AS STATED BY ONE OF THE TECH AT MACK SERVICE CENTER. MY TURBO BUST IS AT 20-24 PSI. SERVICE MANAGER TOLD ME THAT MY TURBO BUST FOR THAT ENGINE AND THIS YEAR SHOULD BE AT LEAST 30-35 PSI. THEY HAVE PRESSURE TEST MY AIR SYSTEM AT 40 PSI AND THERE WAS NO LEEKS. THEY HAVE ALSO REPLACED BY TURBO SENSOR OR BUST SENSOR THAT CONNECTS TO INLET MANIFOLD. AS FAR AS MY TURBO GOES, WITHOUT
