I need some help on something. My pickup just started smoking white at mostly all startups like the valves are bad. Also when i get on the highway and step on it real hard it will blow a puff of white smoke and then goes to black smoke. I dont think its the valves because i just had the head off, checked and o-ringed about 10,000 miles ago. Any help is appreciated thanks.

 

What lift pump are you using? If it is the BD in your signature you are likely going to need to replace that along with the VP44. White smoke is a sign of injection pump death.

Check for codes P0216 to be exact.

 

Ya im using the BD which has been good to me. It never usually drops below 10 psi except for lately its been droppen to 5 due to bad filter i believe. I will have to check the codes but i think i have had that P0216 code on there for quite a few months now.

 

Your filter change may fix this whole thing up. In general white smoke is just a lack of enough fuel to burn the same as Black smoke is an excess of fuel. This can be a result of weak or dead LP, Bad VP, or something clogged in the fuel system. The Clog being the cheapest and easiest to check for.

 

Correct, but if the clog has been there a long time the VP might be damaged as a result. This means $$...

 

I know the filter needs changing so ill try that tomorrow and see how it goes. Thanks

 

If the filter doesn't fix the problem don't forget about the screen on the pick up tube in the tank. Your trucks gettin to that age where the gunk accumulation in the tank may be startin to build up also. It's not as easy to do but you can drop the tank and put it back up in a few hours even doin it by yourself.

 

I think ill do that once i get a rainy weekend. I need to change out the sending unit anyways. I changed the filter the today and i can still get it to drop down to about 4 psi with it only set on stage 4 on the edge and the smarty turned off. Ive never been able to get it to drop below 13 turned all the way up. It may be time to upgrade to a fass system with 1/2" lines to but cant quite afford it right now.

 

Airdog has the same lifetime warranty, better specs and is lower in price. Just in case your interested. Or in my case I went to a belt drive mechanical LP system. I got tired of burnin up electric motors.

 

What does it all take to get one of those belt drive ones and how much would one cost. Who makes them to. Thanks
