Have to rebuild, best options?
Ive got what appears to be a spun rod bearing. What is the opinion as the best way to go as far as fixing this? Its a daily driver 84k 2000 z28 a4. I would love to put a new cam in it while im at it, and add headers, and maybe an intake later on. What is my best option price wise? Id love a more durable engine, maybe forged pistons / stock rods or scat rods, obviously better bearings. Do I need to have a valve job done at 84k?> I want this to be a reliable engine and not be needing a rebuild for a while. I am in the memphis, TN area, and am toying with the idea of getting a salvage ls1 and throwing a cam in it, which would probably be a few thousand, so im trying to see how much I could rebuild mine for, and get another 80-90k miles out of. Any thoughts? Any idea of machining costs or other necessary evils? Thanks
