Engine building guru ?'s
 

Hey pros just have a couple of questions reguarding engine machining 101.

1)If an engine block was line bored, how long of a running time before dimensions would or could change?Would all caps be the same demension?or could one or two be different?


2)When disassembling a short block and you noticed a bent rod,would you check the bore for damage and could a bent rod cause a cylinder to go out of round? If the cylinder was on the border of SO-SO would you take the time to fix it right or just slap it together?


Thanks way in advance

These are just "IN GENERAL" questions.They could be "MY FRIENDS" blocks that I am asking about. :eek:

I was kidding :D :D Put them back up silly. I need answers to my engine building woes,but I have to be a gentlman about it,no name calling or pointing fingers.I appreciate all the info you guys provide.I just trying to figure out why I went from,"you just need a valve adjustment"(old builder) to "the machine work on these blocks s--k" we need to do it right this time(this was from new builder). :eek:

Here is a picture of the rod that came out of the damaged cylinder that was over looked.Would this cause the out of round condition that would also oil down this cylinder?This rod came out of the stock running motor during the first build.


Thanks

Its upside down MOM

When I look at the picture of the rod it looks like it has stock rod bolts and nuts. Arp nuts are usually 12 pt on connecting rods and most aftermarket rod bolt nuts are also black or polished looking from the extra treatments they get,not browish rust colored. Sounds like your "friend" needs some serious motor work to straighten out "his" problems he has found,Smitty

Thats what it is turning out to be,only a couple of hours run time after full machine work and rebuild now its back out and needs all machine work done again to make it right,almost sound like "He" got ripped off and didnt get what he paid for from first builder.But thats just my opionon.
