Interesting note on the PVC valve. I will check that. The dipstick tube was resealed. The lip of the dipstick itself isn't supposed to have a "o" ring on it, is it?
Indeed on the PVC. No "O" ring on the dip stick tube at the block. Up top may depending on the unit. It could be an aftermarket tube and some have a O ring, others have a umbrella like seal.
I am leaning toward the crank shaft seal. That is making sense and I can change the timing cover seal at the same time.
