Your First Engine Job - Checking Cylinder Bores For Roundness And Taper Using An Old Piston Ring

This time around we talk a little about the evolution of the typical passenger car engine and how factors based on that evolution dictate how you may want to approach your build, and we illustrate time honored methods for checking the condition of a cylinder to determine whether it can be worked with as-is or if it needs to be sent out to be bored.

If you want to really learn the tricks to building a great engine, listen to Uncle Tony. Its the same as learning to become a great chef by listening to a 5 yr. old describe his happy meal.

Your videos are a godsend. I have an old Ford 144 inline six I got for free off craigslist. Just having fun tinkering with it and learning to rebuild an engine. Not something I want to take to a machine shop and drop a grand on getting blueprinted. After getting the pistons unstuck finally I was faced with the question of: "should i get this bored?" People on an internet forum were telling me I need to (and I might), but I was thinking "I wonder what Uncle Tony says about this" and you had a perfect video for it.

I always hung out with the old guys when building engines… now I’m the old Guy! Id study manuals to learn, now it’s to remember😂

Have learned more from this series than I did in 2 years junior college automotive technology.

I’ve honed a lot of small engines. I hone might right in my parts washer with mineral spirits. I direct the spout at the cylinder wall, turn on the pump and hone away. The mineral spirits flush the cuttings and grit away as I go.

Tony and Kathy, I believe these videos are stepping stone to mass subscriptions. Tony, you are such a great teacher!

[keeganhache]

Hey man just wanted to say that your videos are very helpful for the guy at home. Don’t listen to the machine shop guys that think their process is the only right way to build an engine. I’m a young kid and I’m porting the cylinder heads on my dads 318 and doing some cleanup or “blueprinting”. We need more mopar videos like yours. It seems every YouTube channel has worked on or talked about Chevy 350 small blocks.

This is exactly the type of information a beginner needs.

While running the piston ring down the bore checking for roundness you can check the ring gap at each stage to see if there's any taper.

Thank you Uncle Tony. These little "tricks", tips are absolutely great for the newbie and oldie as well. I am 68 but I still pick up something new or something triggers connection to a memory that I consciously had forgotten from the past. You, David and Andy are leaving a legacy that will stand the test of time.

I've always used diesel when honing or as cutting oil or anything like that, but growing up on the farm we always had diesel fuel around just waiting to be used as a solvent/lubricant, so that's what we used. We also used it to wash our hands when we were done working on anything that got our hands greasy/oily. The diesel fuel we used back then seemed like it was a lot more "slippery" or lubricating than the ULSD available now, so I use WD40 or lite engine oil as cutting oil now, but still use diesel for engine cylinder honing.

While you're checking for light gaps in the cylinder. Go ahead and check the gap with a feeler gauge at the same time. Save a step. Otherwise, perfect explanation. Easy to follow and very good information

When I built my last stock class 440 we did a lot of these trick because we needed to do a fast build. My head was spinning because I wanted to do it “the right way” but my guy said “this is one of the many right ways and we’re racing” so I’m all for it. I was balancing rods and pistons with a drill and a belt sander and he was checking taper this way!

I remember when you hit 100k subs loving watching you grow. "If you throw it up in the air and it comes back down it's too heavy" UT

[samhicks]

Important last sentence from Tony gave us all a clue, "Now i can confidently get standard bore piston rings" The take away is: Don't order anything or open a catalogue until the block and the rotating assembly is inspected!

[ericsugalsku]

Hi uncle Tony . I have to keep commenting on this series of videos. These are great for real world engine building. This is what most guys and gals are doing in there garage and driveways. I commented before I wish I had these back in the fabulous 80's when I was doing this outside in a driveway.

[SpiveyNatas]

As a rookie and first time hone user. I will try hone oil first and go very slow then try gas when i get comfortable. This has been one of the most informative videos i have seen . David Vizard, Steve Morris and yourself really know how to teach what you know. Your explanations and instructions make learning this stuff way easier. Thanks for sharing and giving me the confidence to try a engine rebuild my self .Stay healthy and happy.

If you have an engine you just want to get back together like this I suggest finding a hone with the fixed adjustment rather than spring loaded. You can do a much better job of honing and correcting the bore in the process. Having honed hundreds of blocks there is pretty well always a few thousandths taper and a fixed stone lets you get that out whick makes the rings and pistons much happier and it will last a lot longer.

Dude I rebuilt my 5.9 cummins, in frame overhaul my first engine and followed your steps without ever watching your videos. Just used my logic, worked out great truck is running strong and great.

[spankyham]

Just 2 items I hope you will cover in a future installment : How to feel the feeler gauge so you know you have the right one because it is easy to go a couple thousands once way or the other between loose and too tight. Second would be which stones to use because there are different grits and that will be based on the type of rings used. Great series! I wish I had a teacher 20+ years ago that taught me this stuff!
