Re: To Babbit or Not To Babbit vs Inserted??
I have just tonight installed AER inserted rods in my B engine. I plastigaged them and they all checked out at .0015 clearance. I was very happy to see this. This is so much easier to work with than the babbitt that was failing one at a time. I lost # 4 babbit and had it redone with Ron's Machine shop and he did a very good job. Then Babbitt rod # 3 failed. Had to tear down again. This is when I decided to go to inserts. AER also rebuilt an A engine for me about a year ago with inserts. This is a very smooth running engine and I am very pleased with it.
Now, I have a question> If the clearance is the same .0015 as the babbitt clearance, why would there be a greater need for pressurized oil system? I would appreciate your thoughts. Thanks, much,
