Wondering if anyone has had problems with their bottom end of their motor. Crankshaft, Main Bearings, Rear main seal. Cant find too much info on the reliability of the ecotec 2.4 and how many miles do you have is 125k+ too much for the bottom end how many miles could I expect before main bearings go out? Anybody out there with over 200k on the stock block?

I believe thst a member is past 300,000 miles with no bottom end issues. In fact i don't recall anyone with any bottom end issues on this forum , but i am certainly no proctologist.
