Hi all,
I have 1964 327 SBC engine,just reconditioned,runs nice but blows a lot of oil in the air filter via the rear sump oulet tube. I am not much experience with American V-8(being European) hence my question.
I initially thought the engine was overfilled as someone has been working at the dipstick and could have blown the surplus oil away ,but I took the oil outof the sump and got only about 2.5 liter .
The engine blows so much oil in the air filter that it drips out of the front tubes,paper filter is soaked.
When I let the engine run without filter cover there is very little blowby from the sump,even when blipping the throttle heavily.No signs of sump pressure,no oil traces on the front filler cap.
I would only expect a very worn engine or one with a holed or damaged piston to do this.
Could it be that overfilling with oil caused the initial soaking and that once the air filter clogged with oil the engine sucked further oil out of the sump?
Any ideas?
Thanks,
Dirk/Antwerp

Dipstick was the original one,but was a bit mangled.
The only place where oil came out was via the rear vent tube;nothing at the front filler one.The amount was massive in the air filter,must have been up to two quarts that was pushed out.
No sign of sump pressure when I give full throttle blips.I'll have to drive her hard without air filter to make shure.

Yes indeed,no PCV valve.I was just wondering if there is some sort of baffle plate missing?
