man, i really dont want to rip the block apart to get my cylinder walls honed. do i really need to do this? ill be getting new rings, pistons and rods

 

Why take 3 steps forward just to skimp on the most important part of an internal cobustion engine. It's capability to seal and create compression..
Food for thought.. You will have the head off anyway, it will only take an extra 20 min to unbolt the block from the tranny and lower it down out the bottom of the car..

First off , tell us whqat you have now and what your looking to change . I have reused oem cyl bores with new bores and havent had issues.. But I have all the proper tools to measure the factory service limits...

 

ok, i have a turbo b16 and the ringlands cracked on all pistons. its out of the car right now with the head off and on a motor stand. i dont feel like taking everything off the block just to get it honed when my sleeves look brand new

 

You need to a dial bore gauge and check the roundness of the cyls.
If you dont feel like taking it apart then dont feel bad when you have oil consumption problems for being lazy.. (thats not a flame just a reality check)
If there still round and the cross hatch looks good you can do it, my tubo b16 had cracked ring lands by the previous owner and they just put new rings/pistons/rods and let it go . I was suprised that when I bought the car with the new rods and pistons it only leaked back 2-4%.
So yes it can be done without a hone , but why chance it when you have the perfect opp to do it correctly.

 

ok, i guess i will then. so if im going to take 25/1000" out of the cylinder then wont i need to get a piston that much larger? and wont that make the sleeve weaker?

 

if you're not going to get a hone job, I say at least get a flex hone and break the glaze before installing new rings/pistons.

 

no i will get a hone now

 

Are you guys using the terms 'hone' and 'bore' as the same? Honing removes minimal material while providing a nice crosshatch on the walls, while boring removes significant material correcting imperfections and would require oversized pistons.

Cylinder inspection would determine the process needed as mentioned earlier. Also, as long as the head is off, and your pistons removed, you can hone the cylinders, just be very careful not to knick the crank. It has been done successfully many times before.

 

but then how are you going to clean off all the minute metal shavings?

 

get the machine shop to hot tank it

 

im not going to hot tank it with the crank still in

 

soap and water. don't use oil to clean after honing
