The factory has no published values so you know I am not referring to that. How do you still hang on to the fact that there is no problem when random people are still losing engines. What do you think caused this guy's hole in the block if it wasn't a thrown rod?

I gave the OP my opinion, based on my background I think my opinion is worth something. Go grab a textbook and read some more about engine failures while I actually work on and repair real life engines with my own hands.



cause you said it yourself. This is still a random issue with much more cars driving on the road than blowing up. I know a little bit about cars and have built many myself, and I will still stand to say this is magnified due to the forums presenting those only w/ problems.
Not saying that the issue is huge, but it is definitely present and there are many cases of premature bearing wear documented on here. The cases on here are also not showing the possible engine issues from owners not on the forums.

Anyhow, the OP asked for a way to increase reliability and since his engine has failed and he needs to source a replacement, it would be smart to add some clearance since he has the opportunity to do so!
