seriously no more of this ****. Thank you.

now on to the question. Yes the car can run like sebba said if the t-belt only skipped a few teeth. But if you think there is too much oil in it why not check the dip stick and see . If there is then do the oil change and see if the noise goes away. Or go to your mechanic and have him perform a compression test on the cylinders. That will instantly tell you if you have any head gasket issues

 

Maybe the jolt caused a timing jump?

 

If there's anything i've notice in this particular site is that an INSANE amount of people here that guess (including some of the MODS) and are constantly giving advice that can make any experienced technician laugh. That includes YOU. If you would only listen to your own advice given above, your post count will be cut in half. Everything he said is completely accurate especially the fact that coolant/water reaching the combustion chambers will result in white sweet smoke out of the exhaust. Your other posts in the thread regarding "white smoke" is absolutely hilarious. What makes it so hilarious is how arrogant you are in pointing how right you are and wrong the other guy is- esp when the other guy has very valid points. Before the days of decarbon cleaners, old school technicians used to slowly induce straight water into the intake of a running engine as a means of cleaning out carbon build up and IT WORKS!

Back to the topic- the 6G74 3.5L IS an interference engine. If you suspect the timing belt has jumped- check your ignition base timing. Mechanical mistiming will result in ignition mistiming. Otherwise, the leftside cam cover is easily removed and the right side has an inspection plate.
If your crankcase is overfull, have your mechanic drain it to make sure it is onlyoil down there and not oil and water from perhaps a blown headgasket. The added water in the crankcase will make the oil level appear high as the oil will rise above the water as it seperates.If it is 5 quarts overfull with straight oil, have him pull out the plugs and check that they are not oil fouled. The added 5 quarts plus high RPMs can blow a ton of oil passed the rings and oil foul your plugs quickly. Did you happen to catch a glimpse at the temperature gauge when this problem initially happened?

What is the security cards feature for in the overhead storage compartment???? Just bought this truck and not familiar with that.

 

The timing belt does not have to be broken. If the engine runs, but nosy and smokes, it's possible that the timing belt jumped a tooth. This will put the valves out of sync, but not by much. I definitely would not be driving it until you have it checked out.

 

I had a BMW with a problem that sounds similar, it was a con rod snapped. It started again but ran horrible. It wasn't cheap to sort
