Can anyone suggest a good source for OEM engine build manuals and reference material? Looking for a good source for tracking down spec's and tolerances for American V8s and maybe a few IL6's.

Hey Brent,

Most manufacturers now allow you to pay for a time period access to print/save/print to pdf all their workshop manuals for anything they have a digital copy of.

For GM: https://www.acdelcotds.com/subscriptions#

For Toyota (AUS): https://toyotamanuals.com.au/subscription

For Audi: https://erwin.audi.com/erwin/showHome.do

For VW: https://erwin.volkswagen.de/erwin/showHome.do

For Nissan: https://www.nissan-techinfo.com/home.aspx

The list goes on. Otherwise if your looking for free manuals, or info, your probably best scouring forums.

Thanks Nathan. I'll give that a go..
