Oil pressure sending unit comes to mind. The oil pan sealing flange comes to mind.

    The choke has a link to an arm on the throtle shaft that the ide screw rides against for setting hot and cold idle. If the link is missing or the arm is damaged, the choke cannot lift the arm out of the way of the idle screw.

    There is a plug at the back of the head for machining purposes for the cam- those engines that used a plug in that location at the back, that plug can leak. There are locations where a blown head gasket does not open a path for coolant to enter the crankcase.

    It is also possible for a rocker cover gasket to leak when new if the cover is distorted or a wire is caught under the gasket.

make sure they are tight
could be time for head gaskets
make sure the old gasket from the old filter came off the block sometimes they come off old filter and stick this causes a leak due to improper seal.

There is a warm up valve on the throttle body(should have 2 small coolant hoses). remove the valve and have someone start the car while you block the port to the valve on the intake. If that clears up the problem you can cut a piece of cardboard to mount in between the valve and intake.should straighten it out.

2001. What would cause oil to leak from somewhere on the driver's side of the motor?
Could be valve cover gaskets. The oil sending unit will also throw out a lot of oil.

Valve body leak 2002 dodge stratus
A vertical cover...I had to ponder that a bit. Still not sure. The valve cover sits flat on top of the cylinder head, with a gasket between them. The cylinder head is where your spark plugs are threaded in. The valve cover rests on top of the cylinder head. It's about 14-18 inches long and about 4 inches high, kind of rounded over so the valves and valve train will fit underneath. A gasket leaking motor oil is very common there, as a lot of oil is directed there and then splashed around to lubricate the valve train. The oil is supposed to drain through engine passages on down to the oil sump- the bottom of engine where oil is kept in the oil pan.

So if you have an oil leak, and it turns out it is the valve cover that is leaking, it's an easy fix-one of the easiest gasket replacements there is.

2002 tahoe back of motor oil leak, already changed rear main
If you have oil running down the side of the block (from above the oil pan) check the lower edge of the valve cover. Those gaskets often fail to seal when the fasteners eventually work themselves loose

Check the fasteners that secure the valve cover to the heads. Torque to 3 ft lbs.

If the leak persists... replace the gasket.

Burning oil but runs very strong with good plugs
Are you sure it's burning the oil? Check your oil pan gasket and valve cover gaskets for leaks. Is the car smoking? (light grayish or white smoke is oil, black or dark bluish is fuel) Could be bad valve seals. Also, main seals can leak oil out onto exhaust parts.

I have a oil leak under my car and my exhaust smokes after i drive it
the smoke is from the oil leak..oil blowing onto the exhaust while driving....where is the oil leak? at the rear of engine? check to see if your valve cover gasket is leaking...it could also be a rear main seal in the back of engine, maybe even the oil pan gasket.

Burnt Oil Smell
Check carefully around the valve covers, this is the area that leaks most frequently occur, and being located next to the exhaust manifold can easily cause the burning smell. There is a very easy to replace gasket under the cover. Other possibilities, shop or you when changed or added oil spilled a bit and that has worked down to the exhaust manifold and is causing the burnt oil smell. Last possibility is that you do have a slow leak on the underside of the engine that is blowing back onto the exhaust system causing the smell.
