kas_1611, thanks for the info on the air filters. I've struggled for years with different VP reps on the idiotic design of their assembly and request for an assembly with a replaceable element with only a shrug of the shoulders as a reply...I've toyed with the idea of just putting on an aftermarket filter, but don't know the intake requirements (flow rates), so have been hesitant to mess with it.
How did you arrive at the particular K&N filter part number and shape, as they seem to have an enormous inventory to choose from? I will look to buy the same next time I go to replace the air filters - thanks!
And thanks to the rest of the contributors on the D2-40 topics! I took my heat exchanger
forward cap off to ensure no impeller fragments had made their way up to the tubes recently (all clear) and decided to just reuse the old oring when re-assembling since it looked fine (about 900 hrs on the engine). I knew better, but at big bucks for such a simple piece, I caved to my cheapness...I must have crimped an edge upon reassembly because it leaked from the bell cap enough to set off my bilge
alarm/pump after just a few hours of motoring. Lesson learned about re-using old orings and especially about carefully reinstalling these caps as they slide on to the tube bundle a good ways before finally seating (use lots of glycerin).
Although you've listed a cheap
source for the o-rings, has anyone invested in an o-ring kit where you size the ring from a spool of the necessary diameter and angle cut and glue the ends to form the ring? Perhaps too much art involved in this, but just curious if anyone makes their own?
