smoking
i know i ask a lot of questions but im still learning my truck when you start it it smokes a white bluish smoke for a minute and then quits the latest thing i done was a cold air intake i hear a hissing sound from the back of the engine but cant feel no leaks cuz i thought a leak would cause it
its a 2000 7.3 thanks |
I am a beginner myself , wonder if one of your glow plugs are not working allowing that cylinder not to burn the fuel prvided to it, but once the heat from the engine is sufficiant starts to burn at that instant. Don't know what a cold air intake is assuming you removed the air heater???? because of that I could be totally wrong. Told that glow plugs either work or they don't no in between.:hellox:

it did take it a few times to start ill check that out wonder how to check it thanks man
|
Possibly just cold. Mine usually only smokes blue when it is cold and needs an oil change.
|
mine smokes when it is cold out and i forget to plug it in. the hissing is probibly comeing from your turbo. im new to diesels so im just telling you what i have experienced:tu:

The only way that I have seen to check glow plugs is to remove them and use a jumper cable put the positive cable on the end where the elec. connector hooks up and the negative on the threaded part. this requires removing the valve covers to get to the glow plugs. Time consuming but can be done in a day. BEWARE of the oil that drips down the glow plug holes the manual says to rotate the motor with a ratchet 3 complete revolutions to push out the oil that fell into the cylinders when you remove the injectors. If oil is not removed it could cause hydrostatic lock of the motor this wil ruin your engine. You are only removing the glow plugs don't know if the 3 times is nessesary but if it were me I would play it safe (lots of compression in there ) simple task compared to a major repair bill.

Its probably smoking clue cause its cold and not burning correctly until it warms up. Diesels need to warm up to burn properly. The hissing in the exhaust backpressure valve, it closes when its cold to help the motor warm up. Your truck is fine
