[DeTomaso] Oil Smoke From Breathers

[Dan Courtney]

Hi Jack,

I eliminated the PCV valve as a cause, next up I'll replace the Mobil 1 with non synthetic oil. The engine and cam has about 2,500 miles now, can it make do without the ZBBT?
If I still have this issue, how does one test for valve guide or valve stem seals (with the engine together)?

Thanks,
Dan
