| Subject: | Induction leaks where and how did you find them |
Folks,
I'm still chasing a small induction leak impacting only my #1 cylinder.
I'm trying to list all of the potential places and methods of testing.
Places so far:
Upper injection port fitting or plug
Injection fitting assembly
Lower injection port fitting or plug
Intake runner in sump
Intake runner connecting hose
Intake runner pipe
Intake runner gasket at cylinder head
Valve cover gasket
Rocker arm oil drain fitting at engine case
Rocker arm oil drain fitting connection hose
Rocker arm oil drain fitting at cylinder head
(last four most likely with loose intake valve guide as a leak path contributor)
Testing methods so far:
Tighten worm clamp screws
Replace gasket
Replace hose
Spraying water on suspected area with engine running (DANGER WILL ROBINSON!)
Where have you found them and how have you found them?
Thanks,
Ralph Capen

Ralph,
What makes you think you have an induction leak?

Carl,
Good question - I ran a bunch of tests as I am trying to flow balance my fuel injection
system. One of the tests was to run at different manifold pressures
25" and 15" and look for a consistent temp change across all cylinders....my #1
didn't change like the others...the remaining text points to a leak in the inconsistent
cylinder.
The temps are well below the danger zone - but you can easily see the difference
in the graphs between high and low power settings.
Ralph
