OK, I guess it's time to rap this up. I tapped the hole to 5/16 thread, wrapped a bolt with a bunch of thread tape and cranked her in. After testing out it DID have a little better oil pressure but I'll be damned if it didn't still have the bad chain slap after it warmed up. I was MADDDD! I figured I had too much work involved to give up so I tore it back apart again, this time I jammed an extra piece of spring in the 2nd tensioner...... so much that I could barely re-assemble it. I installed it and test drove it tonight, no more rattle |removethispart|@ 2500rpm's and up. I ran it hard and ran it easy. I'm gonna drive her now and quit worrying about it, no more noise and it runs great. Hope this helps somebody "get by" one day cause it was a sum-bich for me. Thanks for the help foredom and all others!
