Replaced the timing cover with an OEM cover, did the seal, front oil pan gasket… buttoned it all up and added a pcv valve listed for a 69 Camaro with a 427 and still have the same mystery leak.
Also replaced the valve cover gaskets while I was there… passenger side could have been an issue as the gasket didn’t appear to be well sealed.
My drag and drive is in 3 weeks so time’s running out on the truck.
Next steps… drain the oil and replace the oil pan gasket
Might be time to attempt a 4th fix and sell or LS the stupid thing. Frustrating since it starts easy, idles great, makes plenty of power and does everything well.. outside of the oil leak.
