Do You Know The Dangers of Bad Valve Stem Seals?

Oct. 09, 2022

Before understanding the harm of a broken valve to the car, we need to know that the valve oil seal is Valve stem seals provide a defined metering rate of oil to the valve stem interface of internal combustion engines to lubricate the valve guide and minimize engine emissions.

Do you know the dangers of bad valve stem seals?

Its bad to drive with bad valve seals. Bad valve seals allow oil to leak from the head down into the engine cylinders where it can burn up and exit via the exhaust.

In case, the valve guides and seals are leaking, oil can accumulate on top of the valve and cause it to lose the seat or create a gap. It could further lead to issues with compression, which would cause poor combustion and power loss.

Do you know the dangers of bad valve stem seals?

Essentially, valve stem seals prevent oil from entering the combustion chamber from the cylinder head. A damaged seal can cause engine oil flooding that will lead to engine failure.

What happens if you don't replace valve stem seals? If your valve stem seals are either missing, broken, worn, or installed incorrectly, it will cause your engine to use up a lot of oil than usual. Your engine still can compress, but it will use up a lot of oil.


An issue with a valve seal and/or a piston oil ring will result in excess oil getting into the combustion chamber and burning up, causing higher oil consumption and a whole load of nasty blue-white smoke to spit out of your exhaust
