That is true when the van is moving but I still worry about excessive heat
build up in the engine compartment when the van is stationary and idling,
esp. after a  hard drive, and if a cat is fitted. I think some shielding
may be useful, maybe modify and reuse the WB stuff? I say this 'cause I
noticed a substantioal increase in engine comaprtemnt temps when i removed
the shield (on my I4 conversion) that sits above the muffler on the stock
diesel set up. I'm not saying that the heat will cause probs, just that it
worries me :)
