Hi Allen,
Without baffles, the oil gets sucked into the intake manifold through the
PVC tube and burned in the combustion chambers. If you remove the PVC tube
just after running the engine, you will see oil inside the tube. There
should be none.
I solved the rocker clearance problem by reinstalling the baffles closer to
the cover's inside surface, especially where the rockers interfered and
installed an additional thick rubber gasket for more clearance.
I did some hammering to the sheet metal above the rocker cover for more
installation clearance. The extra rubber gasket is flexible so it can be slid
over the rocker cover and under the flange after the cover is in place.

John,
Yes, the baffles had to be removed for the covers to fit over the rockers
that came with the aluminum heads...
But...if that much oil was blown out...wouldn't it be all over the motor
around the oil filler cap - or could it vaporize and not smell of burned oil?

Hi Allen,
Have you removed the baffles in the rocker covers of your 289? Your oil
consumption sounds like my crate 302 without the baffles. After reinstalling
them, the oil consumption has gone to less than 1/10 of a quart after 2500
miles.

How much oil loss is normal for a fresh 260 - 289 every 3,000 miles?
Is zero the correct answer?
I may have a serious problem. I just drove 2,000 highway miles, mostly at
65
to 70 miles an hour.
The 289 lost 31/2 quarts of oil.
No smoke, no stink, no puddles of oil.
I haven't gone under the car yet, not sure what to look for.
Thanks in advance,
