Timing Chain: I need to check the FAQ and look in the archives, but does
anyone have a detailed run through (pictures are helpfull) for this process.
One that doesn't require the use of the 3+ special tools would be nice.
Plenum: I'll asume I should be looking without the engine running :), but
what am I looking at / for? Anyone got a picture of what I should / should
not see?
As both the chain and manifold require draining the cooling system, I may as
well do it all at once if I need to.
