Let me preface this by saying I've been driving legally for sixty-two years.
When I chose oil and filter in the day I used 10W30 Pennzoil and Fram filters. Now, whatever the house has works for me.
Nothing leaks.
I just bought this van in July and it's painted with Rustoleum forest green with a roller and a brush at the present time and I'd say no, not actually orange peel, sort of 'texture'.
No rock chips on this rig, yet, but over the years I'm sure!
I have in the past broken an exhaust manifold bolt but not in the past couple decades.
Nor cracked any manifolds.
I no longer have a need for an oil catch can or a Hellcat, so no.
Sorry, don't know what MSD is but it sounds like it has potential.
I have had a failed lifter in the past, not now, and most of my vehicles have had worn cams to some degree. I have shattered a rocker arm on a 1958 Ford Interceptor though if that counts.
Walkers? Can't say!
