I'm current striping an engine I got from a wreck.
I planning to get the head worked, new pistons (Compression 9.6 to 1), balance the Crank ETC

When rebuilding an engine, what are critical components that must be changed and what components can you give a cleaned up and stick back in?
EG Cam chain guides, hydraulic lifters, valve spring, seat guides ETC ( and any other components you can think of ?)

Regards,
WayneB

I would throw a timing chain kit in it ( new guides, tensioner and chain ), new rings, bearings ( mains, big ends etc ) check everything for wear, including oil pump, dpending on your application springs can be left as is, likewise with the valves, if you get the head reco'd it should get new guides and seats

Replace every single gasket, seal and bearing, new rings, check EVERY component for wear with a micrometer/plasti-guage.

If any part falls out of manufactorers spec, replace it. Preferrable get new cylinder head and main bearing cap bolts.

I would recommend getting both the block and the head crack tested before even starting the rebuild.

I ALWAYS change the rings and bearings.
If the chain's stretched, replace that, if the guides are worn, which they usually are, replace those.
Oil pump - I strip and clean it, but they very rarely need anything doing to them.
Definitely get new head bolts, also main seals and sump gasket.
I usually get away with making my own paper gaskets - cornflakes packets do quite nicely :)
And haven't replaced mains bolts yet - having said that I haven't built a motor for a turbo or similar yet either, so have NFI if they need replacing for those applications. Probably would look at bigend bolts on a hell performance motor, rather than mains?
Umm....Think that's it, basically if it's worn, replace it.

if you are going to replace the timing chain you may as well get a vernier cam gear set - all the vernier gear sets i have seen come with the chain, crank, dizzy drive and cam sprocket togather, so you get all new stuff with the bonus of adjustable cam timing.
