Well let me start by reasons I've started this thread. I've started this thread because there are a few question I have about engine building and this may help other new engine builders that may have the same questions. I do more then reasearch all question on "google" and i know how to use the H-T search bar but search search doesn't give me a justified answer, so I have resulted to come her and make a thread.

What is "piston to wall clearance"? Is this Bore + Wall clearance of the cylinder wall?

How do we adjust "piston to wall clearence"?

How do I measure Piston to wall clearance correctly with a dial bore gauge?
What is "zeroing" the dial bore gauge?

Is this placing the gauge to the desired wall clearance then measuring the "bore"?

For instances the bore gauge is "zero" to .0030" and the bored is 81.5 mm =3.209" when the cylinder bore is measured it should read 3.209 correct?

For instance say you have a bore size of 81.5mm = 3.209" and your recommend wall clearance is 0.0030". Does this mean the overall bore should be 3.212" ?


Sorry for my Grammer,

Thanks

If you don't know what piston to wall clearance is and cannot understand what that means by the information already on the net then maybe you shouldn't try and build an engine. Same for not knowing how to zero out measuring instruments.

They have videos of all of this on Youtube for chrissakes. They go through the entire process.

I don't think you researched well enough.
What part of this video do you just not get? He almost builds the engine for you. Do what he does and you'll be fine.

BTW 25.4mm - 1 inch.
81.5mm = 3.2086614173228347 inch
This is a common conversion factor and simple multiplication.

 

buy a chilton manual for your car. im sure they have everything on that book.
if you still dont understand afterwards, you probably arent mechanically inclined enough to understand. no offense.

also use your resources. this is the 21st century. everything can be found online

good luck.

 

I dont answer, U fail....
