Just waiting on the pcv hose and I’ll be done for this weekend. New oil pressure sensor, put a new oring on the cam sensor, intake manifold gaskets, throttle body gasket,
new knock sensors and harness while I was replacing the valley cover gasket. Pretty easy really.

I was expecting to find a corroded rear knock sensor, they looked brand new. Ive had it for 50k though lol, somebody musta done these I guess.

Those sensors still look great. Are they AC Delcos?
