When to tear down motor?

[CNC BLOCKS]

I didnt say I had any worn cylinders, I sell my used motors to guys I race against usually when they need freshened.

So now you have engines run 3 years without worn cylinders, but you were saying 11 years???

Ring wear isnt a issue its clearly going to happen, especially with the thin rings of today.

Last time I saw that engine was in 2005 and it had 2 years of Sat. nite racing and 2 champion ships at that time. I am sure the rings are worn and the valve job is shot but it seems to run and run and run flawles.

Had another shop that got an engine in of mine with 8 years of racing it did have a broken main cap repaired the broken main cap rering and bearings and the builder which is a good friend of mine was amazed of the condition of the engine, Said he did not have to polish the crank and could have used the bearings over again. Said it did need rings

Here is a pic of the cylinders after 2 years of racing can't remember how much I had to hone out but it wasn't much.



I would say if your seeing alot of wear in the cylinders maybe using the wrong hone or honing proceedure or both.

Good filters, good oil and machine work they will last more then one or two season not problem.

Have you been hacked by dyno?

I already told you I HAVENT ever had any cylinder wear. You just made a whole post saying nothing, just like dyno does.

So now youve worked on that supposed 11 year old engine in 05 by my math thats 5 years.

Try 01 my bad
