Hi all,

While on this relaxing trip I have allowed my mind to wander around the question as to why the Clasco seems to consume copious amount of oil- a quart every tank of fuel. It runs well, shows no evidence of leakage or smoke but every time I check it is a quart low. I celebrated the dip stick and it appears to be spot on.

I came across this from another forum:

"

One of my other vehicles is a GMC motorhome, they have a known issue with oil consumption if a car engine ( Olds 455 ) is used with the car valve covers. They still have baffles, just not good enough.
the motorhome and high performance 455 valve covers have really good baffles for the PVC and the breather as the breather will suck oil at WOT.

So you do need baffles, good baffles or you will suck oil out of the engine. And no, it will not show up on the plugs.
"

Does this ring any bells with any of you?
