Synthetic Oil change last week 5w-10w 30 honestly cant remember been a busy week
. Well aware of the piston slap its not that...Sounds like its coming from the intake....maybe more the driver side...not sure. Checked the exhaust manifolds last week and there was no signs of leaks...welded up a tiny hole near the pass. side cat. Ive had exhaust leaks on past LT1's and it doesnt really sound like that...Gonna have someone look at it tommorow. Thx for all your help guys...
