Ya know...you said "replacing periodically" and it got me to wondering if..a fresh and clean one would prove any benefit to...engine vacuum.
Surely that's the original part in my truck.
Very curious to see what's inside - what are the chances it's lasted 43 years and works @ maximum efficiency?
I'm anxious to see what's inside.
Does an old booster filter kill brake boosters AND / OR have a negative effect on vacuum numbers?
How very curious.
Whats up with a before and after reading?
You could do a test see?
OMMFG WHAT IS INSIDE THAT DEAL?
I forward the idea that a clogged up booster filter reduces engine vacuum.
If THAT is true, it
would thereby INCREASE blow-by and have a
directly negative impact on valve stem seals.
Follow?
Everything that follows behind it has to
work.against it. That would compound quickly.
I want a new one now.
Thanks Mister B.
Prove the theory!
