When i start my truck up in the morning (usually in the mid-upper 30's) it starts ok but it runs rough for a few seconds and it will smoke heavily of white smoke for about 15 seconds.

My guess is that the grid heater isn't working somehow but im not sure. I don't think the VP-44 is goin out because it still runs fine. I've heard that the grid heater rarely goes bad but it could be a relay?

 

it could be the grid heater......it seems like one day last winter it was VERY cold and i forgot to plug my truck in and didnt let the wait to start light go off and it ran like crap for a few seconds and smoked like crazy haha ...

 

I can tell when my grid heaters are on.... the voltage is real low. If I forget that they are on, & hit the wipers .... they are noticeably slower.

The poor altenator can't keep up with the load... don't add to it's woes by running seat (bum) warmers or other high electrical loads.

 

Thats why we have dual batteries, so we can run that stuff while the heaters are on. Or, do what I do, get an Espar, and you won't need those grid heaters anymore.

 

The white smoke is raw fuel. This is caused by extremely low cylinder temps. You do need to check out the grid heaters. Mine will white smoke a very small amount if it gets down in the 30's. Be sure the heater system is working.

 

with my new vp id hardly smokes, with my old vp it smoked alot when cold at startup . might be a sign of things to come, but my old vp smoked heavy for 4 years before it died.

 

would this be the intake heater?

 

yeah the intake heater is the same thing as the grid heater

im gonna do some checking and make sure everything is connected right. Maybe i missed a wire when i replaced my HG.
