Discussion and questions related to the course Engine Building Fundamentals
I posted this in the Practical engine building Forum as well but still haven’t gotten a response so I figured I would try to post it here.
So I’ve put together Engines by checking the main bearing clearances both with and with out the o rings in between the case half’s in the past and both engines were fine. But this time around I’m building one that is definitely going to have a big increase in power compared to the stockish engines I’ve built in the past and want to make sure that I am indeed checking my main clearance the right way so that there aren’t any problems down the road. So I got a question for ya Andre. When you assemble Subaru engines what is your preference when it comes to checking the main bearings? Do you use the oil o rings in between the case half’s? Or do you assemble completely dry?
Why don't you try it both ways to see if there is a measured difference. Then you will know.
