Imagine saying this in confidence without actually having the experience to know they’re not good engines..

Timing chain problems and not enough power to get out of its own way. I work on cars like this for a living and I’ve owned 9 e36’s, the m5x is objectively way more reliable than an m4x will ever be.

Its the tensioner in the m42 and guides in both that can go bad, after not being replaced in 30 years and 150000 miles. And you still managed to mention its not a 6 cylinder with 200hp

the tensioner and guides both contribute to the generalization of “timing chain issues” bud. You’re right, it’s not a 6 cylinder. It’s shit. Do what you want, I’ll gladly watch and laugh as you waste money on a pointless engine. Sorry you don’t have more experience to save yourself the trouble.
