Do you have tool accurate enough to measure the wear? Have to read the manual to see if the wearing parts are in spec?
Wear isn't always 'visible'
As Dave said, all the worn bits :)

Rhys it depends what you intend doing with the engine....

Are you stripping it for fun and the learning of how an engine goes together if so get some measuring tools and learn how to measure to find the worn bits.

this isnt a bad excerise to do if you dont intend on running the engine in a car you are not going to keep for a few years.

If your building an engine to last well lets see
Main bearings
Big end bearings
Cam bearings
Pistons and barrells
Valves
Valve guides
seals

These are proberly the most common items.

the only way to learn is get a clunker engine and strip n rebuild it an see if you can make it run again, without spending too much money on it but dont expect it to last too long

Get yourself some appropriate measuring equipment (micrometers, inside guages, dial indicator, etc.) and read the manual!!!

Good one Dave :D Helpful as ever

Rhys, check the crank were the end float shins are. If they cut a groove thru the crank down into the area were the fly wheel dowels are located that will cause a oil leak. When this happens the crank is junk.
Other wise as Dave said in his 2nd post. Valves rings and big end bearings for sure for sure. :thumb

Rhys the most important item to check is the Crankcase and this must be inspected with a magnifying glass.

If the case is gone then so is yr motor no matter what else you replace you wont have a decent engine.

Unfortunatly case inspection comes with engine build experience, you can measure all the opening on a case but experience tells you when its STUFFED

hey
when the motor was built by stan a few years ago the case was perfect but there has been some corrosion between the sump plate and the case.
checked out all the flywheel and rear main is fine!!!on inspection with engine running it looks like oil is coming out between the crankcase join where it splits apart??? is there a seal or sumthin to stick in between there where re assembling it?
cheers
