Oil leaking out front of head and through number five rebreather valve

I'm sorry, but I can't provide visual images or diagrams. However, I can describe the general order of gaskets in a 1999 Dodge Durango engine from the top going down:

1. Valve Cover Gaskets: These gaskets are located on top of the cylinder heads and seal the valve covers. They help prevent oil leaks from the top of the engine.
2. Intake Manifold Gasket: The intake manifold gasket seals the connection between the intake manifold and the cylinder heads. It helps maintain proper air-fuel mixture and prevents vacuum leaks.
3. Throttle Body Gasket: If equipped, the throttle body gasket seals the connection between the throttle body and the intake manifold. It ensures proper airflow into the engine.
4. Exhaust Manifold Gaskets: These gaskets are located between the exhaust manifold and the cylinder heads. They seal the exhaust gases and prevent leaks.
5. Head Gaskets: The head gaskets are situated between the cylinder heads and the engine block. They seal the combustion chambers and coolant passages.
6. Oil Pan Gasket: The oil pan gasket is located at the bottom of the engine and seals the oil pan to the engine block. It prevents oil leaks from the oil pan.
7. Front and Rear Main Seals: These seals are located at the front and rear of the engine crankshaft. They prevent oil leaks where the crankshaft exits the engine block.
8. Timing Cover Gasket: If equipped, the timing cover gasket seals the timing chain or belt cover to the engine block. It helps protect the timing components and prevents oil leaks.

An engine does not make oil, but it can spill the oil that should be inside. You could have an oil leak, which means that oil will be leaking from either the front or the rear oil seal. The front oil seal is just behind the crank pulley, the one that drives the fan / alternator belt. If oil is leaking from there, suspect the front seal.
If you have oil leaking from the bell housing, that the the bell shaped metal thingy between the engine and the gearbox. you can suspect the rear oil seal.
If you inspect the engine and see oil leaking from the oil pan under the engine, you have a leaking pan gasket. This can usually be solved by tightening the pan bolts, a whole lot of bolts underneath the engine.
Finally, and this is probably the worst, if you see oil around the breather pipe that goes from the valve cover on top of the engine to the gas intake system, you have leaking compression, that means either the valve stem seals are leaking or the compression rings are finished, and you will have to have the engine overhauled, or at the very least have the cylinder head overhauled.
If the rings are suspect, you will also have excessive smoke out of the exhaust when you drive, especially when you accelerate. Check the exhaust for signs of wet oil.

You nneed to replace the valve cover gasket.

If this is automatic you can be leaking at the banjo bolts,for manual the oil fill plug or oil drain plug,lift up the front wheels put the E brake on,do this all safetly,run the vehicle in gear wait and watch

In 1993, Harley went to the "head breathing" crankcase breathing system. The crankcase pressure is vented into the air cleaner to be routed though the engine and burned. This was a requirement mandated by the EPA. Prior to '93, the crank case vent was down behind the oil pump and a pipe directed the crankcase pressure up to the air cleaner. If you have the "head breather" heads, you'll have a large hollow bolt going to each head from the air cleaner assembly. If whoever did the top end job on your engine left the umbrella valves out, installed them upside down, or put the center plates in wrong, it could be causing your problem. If they replaced the head gasket and did not replace the base gaskets, the base gasket are going to leak. Whenever you take the torque off the head bolts, you must replace all gaskets. Additionally, if the cylinder studs on your engine have not been replaced, they are probably stretched and not holding the torque like they should. In 1996, Harley came out with an improved replacement stud for the Evo engine. The large diameter part of the stud is at the lower end of the stud rather than at the top end like the older model was. If you can't get those, Colony Fasteners makes an excellent set of studs that cost about the same as H-D parts. Blue or black smoke out of the exhaust usually indicates a rich fuel mixture.

Good Luck

Valve Covers, Head Gaskets, Oil Pan Seal and a number of other spots. You'll need to clean the motor with Gunk Engine cleaner and then look for the largest build ups of oil and crud to get a better idea where it is.

where is oil pressure switch/sensor on 2001 nubira

chk your PCV valve. If faulty it will allow oil to be sucked up and burned. Its the critter stuck into the valve cover and has a rubber hose on it. Good

luck, Ned It's an easy fix and inexpensive. So not to panic.

your valves are probably sticking many firebirds have had problems with the heads on the vehicles.. example my 91 firebird burned oil for over a year and a half before a head gasket blew out and consequently cracked one of the heads.. but now im jus down to getting past old vats security systems.. the heads on the vehicle are expensive, so take care of them, replacing the valves may be kinda expensive but is cheaper than hole heads.. also check for any gasket leaks or oil near the valve covers, could be a head gasket.. head, valve cover gasket, valve cover, oil rings a generalized area of where the oil is coming from would be helpful

hi if your engine 22R front engine first in side timing cover where engine bully fitted there is oil seal, next valve cover front side between cover and head there seal not like oil seal half cercle shap it makes leak also front side of the camshaft there is oil seal..
