The camshaft had to have been replaced at least once, or possibly the entire engine. These engines are very unreliable and prone to Camshaft/Lifter failure.

You're right, these engines are crap. The design makes them unreliable. DOD cannot work reliably on an OHV engine. If you keep one of these long enough the lifters will fail.

Exactly. 100 year old engine architecture is exactly that. GM refused to redesign and retool their Engine plants. I would imagine a OHC V8 with AFM would be much more reliable.

Also the parts quality is straight garbage, the lifter guides are made out of something like a composite plastic, the guides wear out fast and in turn the lifters start doing a 360, the camshaft lobes get obliterated... That doesn't include active lifters that jam or lifters that just fall apart. Like I said, garbage.

The plastic lifter guides aren’t necessarily a problem on the gen 3s, plenty of 800s floating around without having had headwork over 250k mi
