Re: [DML] Need some Air


Your intake should be clean.  There is supposed to be a rubber o-ring that 
goes between the air cleaner assembly and the intake, and I almost always 
lose it, so make sure you have it.  I lube that area with silicone grease 
also.  If this area is sealed, then the filter is the wrong type or is 
incorrectly installed; the upper and lower halves of the assembly should 
clamp down on the air filter edge.

The "heat stove" is designed to warm the intake air when the engine is 
cold, to help the car warm up.  It is only important during the first few 
minutes of cold operation, and frankly the ambient temperature here in 
Texas is plenty warm about 10 months a year.  If the valve fails, however, 
it can restrict the intake or heat it indefinitely, yuk.

I believe the hose from the oil cap is to create a slightly negative 
pressure in the top-end, pulling out the small amount of exhaust gasses 
that sneak past the piston rings.  If the valve covers were completely 
sealed, they'd eventually pop or leak.  Getting the gasses out keeps them 
from getting churned-up into the oil.

The intake ductwork is in pieces, but I'm not sure what it takes to get it 
out of the pontoon.  I remember needing to adjust it, but can't remember 
how.  Here's a diagram:
