I have a 1990 740 GL 4CYL. Single OHC...Non-turbo.
While poking down the road it dropped a valve into number 1 Cylinder.
I am trying to find another engine. Anyone tried JapaneseDomesticMotors??
Anyone tried rebuilt motors?? I thought what happened to my car was rare to
unheard of........Any comments on that...or why it happened...Maybe metal fatigue???...Does anyone know what year VOVLO went back to making the B230 engines more robust. I understand that the early years had smaller engine parts...valve rods..springs..??
Thanks for all of the answers that I hope to get.
