So, the air silencer on my 5444 has fallen apart. The part is no longer available and while I could probably reconstruct/refabricate it, I have an additional issue in the short term which is that my engine
room is suffering from decomposing foam in the noise
control barrier. I've ripped out 95% of what is bad but a complete refit
is going to be time consuming given the extent of wiring
and fixtures that will need to be removed for the process. In short, it is not a confidently clean environment
There were two listed original parts
for the engine
...a silencer shaped like flattened teardrop with a vent at the bottom, and subsequently a round flame arrester deal. The latter is what I have and if it had a foam cover it is long gone and I have not found one to replace it.
Given the lack of a spec'ed replacement part being available and the state of the engine room, I'm contemplating a clamp-on K&N filter. I'm assuming that virtually any model that fits the tube (guesstimating 2-2.5") will provide adequate airflow.
There is a certain amount of blow-by that comes out the intake...not a huge amount...let's just say it drips steadily but slowly as the engine runs. Is this going to saturate the filter and cause problems or a hazard? If so, would installing an elbow
to mount the filter vertically be a solution? Does the blow by need to exit or if no exit will it be reincorporated/burnt back into the engine?
Thanks for any and all advice.
