Re: Rounded Head Bolt - HELP!
have been faced with this before.
When doing heads on E series, if you attempt it without Deep 6 point impact sockets, you don't know what you are doing (or simply don't hold the trade qualification)
To resovle this...
1. remove the Rocker train (again six point sockets are highly advised)
2. block off all oil galleries as best as you can
3. get a nice fine file and remove the rounded edges off the bolts
4. try again with a 14mm impact socket...if it feels like slipping, then stop and file down, swap to a 9/16 impact and continue to file until it almost fits and then bash it on.
these suckers are TIGHT to begin with.
Dont be afraid of destroying the bolt, because when doing a head gasket on these you should ALWAYS replace the head bolts...my last set cost me $18 trade.
