Useful, but most of the stickies are stuff you can't find in your manual.

I've seen that they show you HOW to do it, they just don't tell you... how much to do it.

Nice! Referenced.

my honda manual says the flywheel bolts are 76ftlb torqued not 87.. I just did a clutch so I was curious when I saw that number on this thread.

another honda technician says so too.

yeh those connecting rod specs must be wrong because i torqued them to 23ftlb and tried turning over but it didn't budge, was so tight that i ended up loosening the harmonic balancer bolt, can someon give me an accurate connecting rod torque spec for a y8?

they speak of the actual size of the bolt which is calculated by the threads not the heads size. FYI
