So, a leak could cause richness? It seems to only be rich while at lower
speeds, especially idle.
Could you be a bit more clear on where your leak is? If it's a bad
hose, then you may be able to trim a bit off the end of the hose and
make a better connection, or you may need to replace the hose.
All hoses are replaced. On the left side, under the throttle body; goes to
the M.P.S..
This would apply to both the PS hose and the AAR hose.
If you have a crack in the IAD casting, then you need to replace it,
but I've never heard of one of these breaking.
When I remove the throttle body, I will check it.
most leaks in that area will only affect idle speed, but a large leak
at the PS hose would cause rich running, especially at idle.
The openings all were clear and the oil clean about a month ago. Can I
use
oil that is five years old as filter oil? I would think it is no good
for
engine oil (additives broken down).
It's probably still good for either use, but using it in the air
cleaner would certainly be fine.
Cool. We can use it when my Father gets his '64 Beetle on the road (would
want to change the oil every 1,000 to 1,500 miles due to it sitting so
long).
Thank you,
