Question on crank case ventilation
I have a 65 cutlass with a 330. 45.000 miles, Had the upper end redone.
It is blowing oil out of the oil fill tube not much but thats what it did before I had it done. Pvc valves did not exist then The CVS works with original parts is connected . Is there a way to stop this or convert it to a PCV. Thanks Kevin |

Fresh air
'64 and '65 Cutlass had PCV valves!! PN 6420092 type 639 for V8...PN 6421971 for V6..you had me wondering there for a while, must have been a trick question..
 Also the valve cover should hook into the air cleaner via a metal tube and a couple of gromets according to the parts book..

Need Air
The only hook up is from valve cover to air cleaner via a tube
with a A/C Delco part ( a little roundish piece with a flapper inside) between the two, that part hooks to the rear base of carb. No other holes in valve covers. |
