    Somewhat of a novice.........can this be done, by me.........or am I looking at a "service-call?

    With the engine running, full of oil, look under the vehicle and see if it is dripping or running out between the engine and transmission. It may be a rear main oil seal gone bad.

Oil change from the dealer. I have 2016 f150 with 37000 km

Yes it can be at high rpm or extremely hard loads it can cause timing chain tensionors to wear guide excessively. Also it could cause PCV system ,which evacuates emissions vapors from cylinder blow by and H2O vapors ie. steam (while returning said emissions and contaminated vapors to intake to be burned throughout the intake during emissions cycles and checks) to oil out PCV(positive crankcase ventilation) Circuit making check valve stick, fail, or malfunction causing oil directly pull ie. vacuum from intake cooling cyclinders causing problems

Could it be a pluged pcv causing oil to get in number1&2cylinders

Conceivably. A clogged PCV valve could cause crankcase pressure to rise and force oil up along the pistons, but one would expect it to occur on all of them, not just those two. Also, some vehicles don't even have a PCV valve. Without knowing specifics on your vehicle, I can't make specific answers.

2003 Toyota Landcruiser - dripping water from AC unit inside car, passenger floor board...AC works fine...clogged drain line ???

yes the drain line is clogged,, its located along the firewall and is a bear to see,, if you get under the vehicle, and look along the edge you'll see it don't blow air into it , that will just make the clog worse, take a wire, and gently ease it up into the tube, working slowly , be ready to get wet,, once you loosen the clog the water behind it will flush it out, and sometimes there is quite a lot

I am trying to find out where the fuel filter is located on a 1989 Jeep Cherokee?

The fuel line should be running along the inside of the frame on the driver's side of the jeep. Under or around the driver's seat there should be a quite large inline fuel filter, again, along the inside of the frame. You need a special tool purchsed from the parts store that unlocks the fittings.

My car will stall when stopping. I have found oil in the air filter compartment, and the car runs well otherwise. In other cars I have owned this was fixed by replacing the PCV valve, yet I was unable to...

Yes, this vehicle is equipped with a PCV valve!

It is located underneath the intake manifold, slightly above the oil filter.

Although difficult to see, if you look from the driver's side through an opening under the intake manifold, you'll see a sensor. Look to the left of the sensor and slightly below for your PCV valve.

It is a little elbow with a clamp and may be covered in oil.

Your patience and dexterity will be tried, however you can replace it yourself.

Please let me know if I may assist further.

Shooting oil out of dipstick

Your engine breather system is blocked....this means that the only way that the compression caused on ignition that is getting past the piston rings and into the block can escape is via the dipstick tube.
Check breather for kinks and some have filters ensure that these are not blocked

Oil coming out of dipstick

What engine? The oil level is good, not to high? If yes, it has too much crankcase pressure. Change the PCV valve and check the crankcase air filter. Also make sure you have vacuum at the PCV.

2004 dodge ram 2500 waisted oil.

Check Out your pcv

" Inspect the Positive Crankcase Ventilation (PCV) valve. Shake the PCV valve to verify that the pintle inside of the PCV valve is free. Replace the PVC if the pintle is not free"

and then check this Tech Service bulletin TSB 09-05-00 Spark knock and oil consumption due to intake manifold pan gasket oil leak. .
"If the intake manifold plenum pan gasket is leaking, an additional vacuum source will be created inside of the engine at the location of the pan gasket leakage.- Engine combustion blow-by gases, oil vapor, and air from the crankcase filter/breather may be drawn past the leaking pan gasket and into the intake manifold. In most cases when this condition occurs, an engine at idle will create the highest vacuum and lowest amount of engine blow-by."

All instructions for the test and fix are in the bulletin. Don't do anything to void your warranty this is for your information and knowledge.

Your oil manufacturer should not be an issue if it exceeds specs for your vehicle (most do)
The oil weight may be an issue if you are not using the recommended weight. (still unlikely)

Plugs are different definitely stay only with the manufacturer recommended for best performance

While 1 quart per 3000 may not seem outrages to some any oil leakage from a new vehicle should be unacceptable.

I cannot suggest any other recourse than these other than to make sure you have all your trips to the dealer documenting the complaint and the resolution or lack of solution. If you have tried all your resources to fix the vehicle it may be time for different direction and a different group of professionals.. So maybe yes to your question " there sumting wrong wit my truck???"
