I know I posed this question in the Advanced section. But I havent gotten the reply I was looking for yet. Here is the link for those who are interested. https://www.evolutionm.net/forums/sh...d.php?t=201035

I want to know how important it is to use a torque plate when honing. Is it necessary? In my thread in the advanced section, member hostile posted a link to where I could find a torque plate. Needless to say it is rather expensive.

If this is needed, then I will be sending the motor out to be built. If not, then I can do an in chassis swap of the piston and rods. You can see the dillema.

For those who build their own motors or vendors, please reply so I can get a definative answer.

I also posted this in Buschur's forum but have not gotten an answer so I figured I would put it here in this forum where the number of people viewing is higher.

Thanks again for any help.

 

When installing new rings you should always bore hone the block. You don't really "need" a torque plate for this since all you will basically be doing is roughing up the cylinder walls so to speak with a new cross hatch pattern so the rings seat and wear properly. They cannot do this if you don't hone them since the walls are glazed and not rough anymore. When boring i would definetely say use a torque plate. Good luck.

 

^^I know that. What I want is a answer from somebody who builds these motors. Do they use a torque plate? Does AMS, BR, SBR, ect when they build motors use a torque plate?

 

yes sir.. Always use a tq plate! Honing, you can get away with it, not recommended. Boring, definately have to use it.

thanks mark. Not recommended. That was the answer I was looking for.

 

Can we get away with installing a set of 'stock bore' forged pistons (Wiseco or JE etc) without rehoning the block? Engine maybe with less than 30000miles?

 

you can.. but a fully forged piston should atleast get a hone unless the motor was brand new. I know many have done it, but you should hone it. Its not going to hurt anything, maybe some oil usage later down the road..

Depending on how many miles are on the Block, you might get away with just a Deglazing process. With this process, I believe you wouldn't need a Torque Plate.

 

No matter which way you go, just make sure to measure the "roundness" of the cylinder after your honing process is done. I have seen so many "honing" jobs that egg-shape the cylinders.

this is where my concern is. I have 25k on the motor and it needs the new pistons due to #4 cylinder piston being cracked. It really didnt damage anything else except the head. No metal made it into the oil. No scratches on the cylinder walls. Just some scuff marks that wont catch my nail. I figure I may be able to just get away with honing the walls and installing the new pistons and rods.

 

bump, just curious to see how it turns out. similar to my problem with #4.
