cylinder boring

[richardtan]

Dear Sifus,

Can an old engine be bored to make it as good as brand new?
To what extent can an engine cylinder be refurbished to be like new?
Also, is it cost effective?

regards
Richard?

an old engine can be bored out, u need to see the manual (if stated) on what is the maximum u can shave off, OR just bore the minimum dats needed; dat can be dependent on how much u need to shave or the available pistons selection

u only can bore not more than 2mm

Thank you Sifus,

does it really help make the engine nearly as good as brand new, if done correctly?
I am thinking of getting a second hand car and refurbishing the engine. But not sure if cost-effective. Thanks for reading.

regards
Richard

reboring and rehoning the cylinder wall... fit in new pistons... refurbish ur conrods and crankshaft... new main bearing, new conrod bearings, new piston rings, new valve seal...

all the above done with proper measurement and clearance as specified in workshop manual... i'm sure u will get a close to brand new engine after that...
