The purpose of the valve stem seal is, to prevent the oil from the cylinder head; entering the combustion chamber. So, the valve stem seal, plays a critical role in, controlling valve lubrication as well as oil consumption. But, if the valve stem seal is worn, the valve guides may be either; starved for lubrication or flooded with oil.

Fel-Pro® Valve Stem Seals. Fel-Pro engineers analyze the OE design for every application. The OE design is tested and benchmarked. Based on the analysis, we determine the material used, considering the durometer (relative hardness) of the rubber, temperature requirements (both extreme heat and extreme cold), resistance to common oil types, tear-resistance and leak rate.
The valve gasket seals the connection between the valve cover and valve chamber. If there is a buildup of oil around the outside of the valve chamber where the cover attaches, the gasket may be worn and require replacing. To confirm the source of the leak, wipe away the oil buildup and run the engine for a short time. If oil returns to the same ...
The fact that you are seeing any oil in the intake ports tells me that your intake seals are leaking. That's very likely the source of your smoking problem. BTW, if you look closely at a Harley valve seal for the shovelhead, you will notice that they are not all that special.
They often leak at the rear of the cylinder bank, and a cursory inspection would make it seem like the rear seal. I'd definitely have a real close look at the top of the engine right in front of the false firewall. Also have a look at the oil pressure sending unit, below and behind the oil filter housing.
The valve covers are located at the top of the motor and they are a common source of engine oil seeps and leaks. The valve covers are just that, protecting covers over the valves and rocker arms at the top of the engine. The valve covers are bolted to the top of the engine and a large egg-carton-shaped gasket made of rubber or cork that seals ...
6 Signs Your Valve Stem Seal Is Leaking. Valve stem seals control oil consumption and lubricant in an engine by allowing a specific amount of oil inside the valve stem as it moves. A controlled amount of oil is crucial in maintaining adequate lubrication. Otherwise, too little oil can cause various components to wear as parts rub together.
Posted August 29, 2013 (edited) I see a lot of older YZ250 with oil leaking from the rubber portion of the Power Valve linkage cover gasket. The oil always covers the area around the water pump. A few years ago I figured out that the cause of this problem is wear on the main powervavle shaft and the bore it rides in.
Valve packing is a contact seal and its mechanism relies on maintaining a very small gap between two surfaces, just like with every other seal. What causes smoke from a leaking valve seal?

A HM oil might help. I've seen stem seals break like glass, ripped, and valve stems totally missing the seals. The best thing to do is replace them if a HM oil doesn't work. Using too thick an oil to stop a consumption issue from bad stem seals in an otherwise good engine might cause other problems over time.
on a normal small block, the valve cover mounting flange is flat behind the mounting bolt hole, which allows a gasket to seal and prevent oil from even getting to the mounting bolt/stud threads and wicking out. with the way these heads are machined, the oil is always splashing right on the threads, so it's gonna find it's way up the threads and ...
My OCV solenoid valve was leaking through the o ring even with the oem replacement. The shop tried a bigger ring and it still leaked. They ended up cleaning it off and using hondabond with the ring to seal it in. No more leak. I know some have said hondabond is not recommended, but figured that is better than leaking oil all over.
For small leaks, the location matters the most, as a leak from the front crank seal or the timing cover will shorten the life of the timing belt or engine drive belts, while a valve cover gasket leak will get oil on the hot exhaust manifold, potentially causing smoke or even fire.

Has classic valve stem seal leak symptoms....smoke after idling for a long time, or smoking after going down hill for a few miles. Smells like oil. Oil consumption was about a qt/1000....then qt/500. In the last thousand miles it has used 1 qt/100 miles.
i seem to have some oil leaking from around the oil control valve on my 06 mazda3i 2.0. from what i have been able to find, it seems that this leak is fairly common, but i couldn't figure out if it is usually the valve itself that leaks or if just changing the seal out will solve the problem.
Bad Valve Seals Symptoms. 1. Blue Smoke From Exhaust. The most common symptom of a bad valve seal is blue smoke from the exhaust pipe. This can either be caused by a leak of the intake valve seal, which causes the engine to consume and burn oil inside the combustion chamber. It can also be an exhaust valve seal leaking, which will push oil ...
Leaking Valve Seals. Leaking valve seals result in blue-gray exhaust. Engine oil is leaking past the valve seals and into the combustion chamber. These seals allow the valves to move up and down while providing a thin film of oil for lubrication. Exhaust smoke occurs when too much oil leaks past the seal.
The simple answer is: A seal that fits around the valve stem and valve guide to prevent oil leakage. The more detailed answer is: A valve guide seal, also known as a valve stem seal or valve seal, is located on the engine cylinder head inside of the valve springs.
