VNL 780 - D13 oil in pipe and white smoke

Only when parked and idling is when the smoke come out, when the trucking is moving or when I raise the gas no smoke.

 

Get it to a shop and get it checked out ASAP or it could cost you a lot of bucks. On my truck after doing a few checks I did a valve adjustment, replaced the seventh injector but the white smoke didn’t stop. I decided to send it out on a trip to see how it’ll do, and then the unfortunate, a piece broke off the number 5 valve and dropped in the engine, busted a liner, then came out of the exhaust manifold through the turbo. I didn’t get to find out what was causing the white smoke on idle but it could very well be related to the cause of this big costly problem. Thanks to Nasriza! He just rebuilt the engine for me with new turbo and all the nine yards. That man is a genius, he did me an outstanding job!

 

I can’t tell you what yours might be but my input will be get it diagnosed by dealer or a good capable shop with equipment to do so.

Mine dropped two valves not long after this post and I had to get the engine rebuilt so again get it into a shop ASAP!
