VALVE SEAL™
OIL CONSUMPTION REPAIR
Bar’s Leaks® Valve Seal™ Oil Consumption Repair is the
fastest, safest way to solve your vehicles oil consumption
issues. Your vehicle is a good candidate for this solution if it
does not use more than one quart of oil per day. Depending on
the severity of the leak the first thing you may notice is the
engine oil level decreasing. There may be bluish (blue and/or
gray) smoke coming from the tailpipe upon starting the vehicle,
more noticeably after it has been sitting for a while, like
overnight. Your engine could also be consuming oil and you
don’t see any smoke or leaks, as it is being burned gradually.
Use with all types of motor oil, including regular petroleum,
high mileage, synthetic blends and fully synthetic. Can be used
to top off oil when low, or to replace a half-quart of oil when
performing an oil change. Works with ALL gasoline and diesel
engines.

What is a Valve Guide 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. An automotive engine can have as
few as 8 valves seals, or up to 32. These
are located on the intake and exhaust
valves and have a pretty difficult job to do
as they need to allow some oil to pass (so
that the valve stem and guide receive
lubrication), but need to prevent larger
amounts of oil from going into the
combustion chamber to be burned. When
too much oil is burned the vehicle will
consume oil, emit blue exhaust smoke and
cause valve carbon build up. This is bad
for the environment, and also the emission
system on the vehicle.
Leaking valve seals can account for over
half of all oil consumption issues.
It is amazing that such a small part that
only costs a few dollars each can cause so
many big problems.
