ok guys....i got a 03 c5500 with a 6.6 duramax...i just bought this truck and now i'm getting sick of it
...anyway, we bought it and drove it home 600+miles...well after about every 100 miles, we would have to stop and put water in it because the low coolant light would come on and the engine would shut off when we come to a stop...i'm not a complete dummy when it comes to diesels but this one has got me stumped....there is no steam/smoke coming from the tailpipe...i am positive there is no leaks on the engine or etc...it is absolutely not overheating and it is not building any pressure in the overflow tank...no puking/etc. like i've had before in another truck...runs smooth and normal...well when we got home, i shut it off...next day i went out and started it(normal) and drove it about 4 miles and shut it off...next day i went to where i parked it and tried to start it and it turned about one rev. and stopped...i hit the key a couple times and it was locked up sounding....i kept hitting the key and it finally broke loose and started...ok, now i didn't drive it then, just let it run alittle and shut it off...next day i went to start it and it was fine.....i needed to get some welding done on it so the next day i started it and drove it 1/2 mile to the welders shop and shut it off...couple days passed and he called me and said he finally got a spot open to work on it but when he went to start it, it locked up again....now i'm sure its getting water in a cylinder but i don't know how...i know i can take the glowplugs out and see which cylinder it is but what do i do then? you would think if it was a headgasket, it wouldn't have made the 600+mile trip home without overheating or something....i have read that it may be an injector cup cracked or not sealed properly, is this possible? i have no previous history about the engine but i can tell someone has done some work on it(can see fresh silicone/etc. like its been apart at one time) maybe they put injectors in it....it runs excellent with no smoke or blowby and the oil is clear and not overfull...is it possible for me to find the cylinder and have that one injector cup replaced....surely someone on here has some ideas for me...i wish i could just call someone or have them call me to discuss this..870-476-0115..Jim.....thanks in advance for any info
