This week, I started to get blue smoke out of my 2.8 TGV. It occurs intermittently while it's relatively cold, and only at idle (after about 15-20 sec) , or starting to move from a stop (big ploom). it doesn't always do it.
This engine proably is still under 30k, and didn't smoke ever until this week. Some things that have changed on it are:
- increased donaldson pre-cleaner on snorkel from 7" to 10" due to realization that 7" was way to small for this engine.
- drove at highway speeds last week running at 215F for 2 x 2hr stretches. Turns out that 2 months ago, when I completed my Webasto install, I did a horrible job at bleeding the coolant, and was 2 gals short (of a 5 gal sys). Now it is running at 200F on highway, and under 180 around town.
- Axles, tranny, T-case and fuel tank all plumbed into extended breather manifold.
I know that blue smoke tends to indicate oil in the combustion, but I'm uncertain how to begin the inspection/process of elimination on this.
I'm going to completely top off tonight and begin monitoring coolant and oil consumption, but does anyone have any further insight?
