Y'all got me smilin. Wife looked over and asked what I laffin about.
I was goin more toward the transmission fluid problem he specifically mentioned. I been runnin a bv on tranny and tcase vent on my auto buggys for years. Got idea from randy torbett back when uroc was around maybe ten years ago or so. ( jwend that was an older rock crwl organization before werock got big....fyi
)... lots of comp guys do it, I'm surprised it seems exotic to you. Most run bellows on axles, so not a issue there.
No wasent even ssugesting anything for motor... but redranger may be on to something.
Just throwin out remedies to his prob. Hope it helps!
