Not sure what u mean exactly. You don't need to remove the rocker boxes to run the overhead. Nonetheless, i always put the engine on one of the 3 adjustment marks before I do anything else. That way I have a definite starting point. If you are going to remove the rocker boxes, then there is no need to loosen the valves first.

Loved your video. I Have a question if you could help. I have alot of fuel coming from my exshust manifold on my 85 Peterbilt 400 big cam. It smokes more white smoke then blue, and sometimes black in color under heavy load but clears up. Engine still runs strong. Fuel leakage appears to tame down once it's eng. Is working and warm up to 170. But starts again setting and idling. When I take off after idling, it smokes like a Freight train for a few miles before it clears up. Injectors? Haven't tried ATF in fuel filter. Any ideal?

@lifeintrucking.eduardomorales

4 жыл бұрын

Mix a few cans of seafoam in fuel. When that fuel is done, then add 2 bottles of atf in each tank of fuel. You might see a different color of smoke due to the atf. Hopefully that will get your injectors working right. If it doesn't, you might need to adjust your injectors, or time for some new ones. It sounds like one or more injectors might be staying open(leaking). You need to be careful with that. It can cause damage to engine.

Do your oil changes when needed. Watch your antifreeze. If to old, might be time to change it. One of the things many don't check would be your water belt tensioner pulley. Check if there is a grease fitting. If not, there should be a plug. Take it off and replace with a fitting. Keep it greased. Pay attention on symptoms for bad injectors or camshaft. If your truck is running strong, then you should not have that problem. You have a good engine, just always pay attention when it speeks to you!

Next time around save yourself the hassle of syphoning. By re-priming your PT pump and filling the fuel filter with a mix of 80% automatic transmission fluid To 20% diesel... And pour a gallon of sea foam into your tanks.... syphoning and washing the cylinders is still the best method But usually the detergents and natural lubricants in atf and diesel will loosen up the carbon in the cylinders and when the engine is at operating speed 1500 rpm or so. It’ll just blow that shit out the stack for a little while. And then it’ll run clean The sea foam is just a post rinsing kinda and stabilizer for the fuel.
