The 2v where the plug shooters and it is because people won't tighten the sparkplugs. The early 3v where the broken off plugs. I can repair a blown plug thread in a van in under 45 min. I can do an entire set of 3v plugs in a little over an hour. Even if a few break off. Biggest problem with ford's today is valve springs. Break them all the time in all engines.
Gm doesn't need ohc engines because when you can achieve 110% VE with pushrods, well, that explains it! They just can't build a lifter to save their lives.
The Chrysler transmissions you are referring to have been out of production for over 10 years. They have either diamler or fiat transitions now. Biggest failure now is the multiair engines and the hemi's. The hemi eats camshafts, looses oil pressure, and breaks manifold bolts like it's going out of style. The 3.6 v6 eats camshafts and oil coolers.
Honda can't build an engine to save it's life for the last 10-12 years.
Kia/Hyundai could not build a 2.0 or a 2.4 to last over 90k till last year.
All Toyota vehicles smell like curry?
Subarus just plain suck. Only reason you see them everywhere still is the eccentric owners that dump tons of money on them to save the planet.
Long story short all cars and trucks now are just terrible. Unless you have a new 6.7 ford. Best truck/engine comb hands down.
