L98 Oil Fill Cap Thread Size ?
Well the Title sez it all. At my last Auto Cross I got Black Flagged for dripping some Oil. After letting the Car Idle for an hour on my lift its not leaking hardly a drop. So I'm thinking my Engine has more Blow By than my PCV can take and Oil is getting pushed out the Valve Covers. I'd like to try a Screw in Breather into the Fill Cap. I know my 1990 L98 uses a different Thread than my 1996 LT4. About 14 tears ago there was a Topic with the same problem but the Part Number of the Breather that Worked got eliminated.
