engine rebuild

im having to take the engine out to weld the frame so im thinking engine rebuild just because one cylinder is leaking oil slightly onto spark plug so mayaswel do rebuild something i never done before while engine is out my question is do i get a standed set of ring and slap them in or do i need to rebore the pistons if so wouldnt i need like larger rings for 800cc bore kits they have advertised or would i need to have them sleeved professionaly bit of a grey area for me always tempted to try doing this though on a veichle

 

nevermind rang the shop up they said they just give it a light hone should be rite think i will just go standed size rings if i do it maybe change cam chain and friction plates and leave it at that

 

Split the cases and replace the alternator chain guide and replace the starter clutch rollers and springs. The chain guide fails from age, and the rollers and springs from use. May as do both jobs while the engine is already out.


Also, the shop won't really know if a light hone will do the job until the cylinders have been measured (unless the original cross-hatching is still evident).
Are you sure the rings are where the oil is coming from and not the valve guide seals?

 

never thaught of valve guide seals ....on this one ..but i decided to put this off anyway because i live in a share houese and the owners have a large dog that gets into everything i think i will wait till i have my own place i could have it apart for a month or more

 

You don't have to remove the engine to replace the valves oil seal.

ok i spose there under the valve cover with shims and what not still have to check the clearence of those anyways ...

 

If it's the oil seals the head will have to come off. It can be removed with the engine in situ. Check the clearance after the oil seal job.
