Re: engine knock
check your header bolts. mine started knocking cause i lost a bold in the header. also, obviously check your oil level.

Re: engine knock
Keep a close eye on your oil pressure! If you don't have a guage install one. If it sounds like a bottom-end "hard knocking" you could have a bearing failure, or it could be "piston_slap".
