Pouring oil in not sure where it is going

Check to see if the oil cap is on correctly. Take the oil cap off and put it back on. If you just put some oil in your vehicle some of the oil may have spilled onto the engine and will burn off unless you clean the oil off the top of the engine. It could be a valve cover leak. Look under the car for an oil leak on the ground and if you see fresh oil then take to your mechanic.

You may have a minor oil leak and not see any dripping on the ground. The van is under load going up hills and will run slightly hotter. If there is oil leaking in or around the exhaust manifold it will give a burning smell.

Look underneath. Is there trans oil leaking? Its red and thin so should be dripping easily.
Is the trans correctly filled? Low oil will prevent it moving. Check trans oil with engine running. Should be near high mark.
Is the smell oil? Or are the brakes jammed on?

check for oil leaking onto the manifold from a leaking tappet cover gasket

Check the valve covers for small leaks, the oil will run down onto the exhaust manifold and this causes the burning smell. Oil leaks on this model and engine is a very common issue.

Cheap way to go is tho change the filter and that will tell you if you have metal in the pan, if you do gears are bad or smell the oil, if it smell burn or looks darker than what it should be

Hi Kiwi, Have a look for oil leaking onto the exhaust system, particularly onto the exhaust manifold. I'm fairly sure that you'll spot something from there. Regards John

Make sure the drain bolt is tight and filter is tight first then look for your self and see If the value cover has oil around it if so it is the covers if not it could be your seals

If you're sure the transmission is slipping then it's not a universal joint causing it.

Classic test for loose universal joint in driveshaft: you'll feel the car vibrate, vibration will increase with speed. Getting on and off the throttle when you moving will cause the vibration to change- might get better, might get worse but it'll change each time you let off the throttle and then push it again.

Are you sure the transmission is slipping? If you feel that it is then the first thing to do is check the transmission oil. If it's low then top it up, that may solve the problem. Smell it, if the transmission is slipping it'll have a burned smell and will be other than nice bright red in color. If it's slipping you'll also see dark matter in suspension in the oil and the oil color will range from dark red to black.

If it's definitely slipping but the oil isn't too black yet you can sometimes get more use from it by putting a thick transmission goop in it- be sure the transmission is warm when you pour it in and drive it a few miles to give the goop a chance to mix in well.

there is a port and it takes r123a and it has a green port on it but if it's leaked out you mave have to have it vachumed out, if you charge it be sure to get R134a with oil so that you don't burn up the pump, when the thing leaks it loses oil.
