Unfortunately, I learned this the hard way as I was one of the first to install the 2L sump after their last manufacturing run. The long screws bottoming out caused my engine block to crack resulting in thousands of dollars in damage.

The correct screw length is on the right. You should have received replacements already.

Oh, major bummer! Very sorry to hear that :-(

I did receive the replacements, but haven't had a chance to give any of it a try. Will be a post Easter project at this point...

Thanks for letting us know!!
