I am new to the forum and just purchased a 62 m-62 that was an ex forest service fire truck with wyoming. It had the contential gas engine i was told from the guy i purchased it from but had had a hole in the block when he got it. He replaced it with an LDT-465 not sure of the year, hours, or miles on it and neither was he. he added a mack turbo not sure what number. He added an electric pump and added another filter right after the pump. He redid all the wiring and other what nots as well.
After i purchased it i drove it the 40 miles to the city for the night and it ran great no issues or anything plenty of power on hills. the next morning i drove around 90 miles heading home and started having issues. It started cutting out under WOT and puffs of blue smoke. the night before and the morning it rolls coal like a freight train in all gears until i get to around 2500rpms in 5th. then on WOT itll roll it again, but no blue smoke at all. But it did smoke excessively on startup until it got warm.
after the blue smoke started going up a 6% grade it really started cutting out bad and was only going like 15mph up the pass. after getting down on the lower ground it ran great again. I refueled and added Howe's like I had done the night before. after driving for around 40 miles it started cutting out again and just not having power at all and killing every mosquito within a 20mile radius. it just smokes very excessively. he said he had the pump turned up but maybe its way to much.
i finally got to my destination and i noticed it had a fuel leak right near the fuel lines at the ip. i took the ip lines off and cleaned them all out and cleaned the ip threat holes to make sure it just didnt have dirt in it. the fuel leak is fixed. purged the air out and still very excessive smoke. and lack of power. it also has a **** of a tapping sound in 5th doing around 2000- 2750 rpms like a lifter. it does it all gears at the high rpms but it is not that loud with it parked in neutral and i revved it up. the oil level is good in it and no obvious leaks.
Any suggestions on where to start?
He said he had replaced all the filters when he installed the extra one and the electric pump. I added good clean #2 diesel at both fillups and Howes diesel additive as well.
