Boring an engine with a hone?
At the machine shop where I once worked, we would reline cylinders used to extrude melted plastic for record (remember them?) production. Anyway, the stainless steel liner was pressed in the cylinder, welded, then honed to size, don't remember how much honing but I'm estimating at least 0.1" or so. Anyway in those days I had a dirt bike (RM250) that I bored out with the hone, worked great as far as I could tell. I honed it to 0.0005" larger than the minimum size. This hone was the type with the rack and pinion feed, positive feed feeling. While honing you could feed taper in the bore, out of round, and when it cleaned up, nothing like those springy break cylinder hones. Anyway, remember my economy car with the bad engine problem, the 2002 escort? Instead of spending $4k on having a mechanic replace the engine with a Jasper remanufactured engine, I'm considering getting something else but working on the Escort. So I'm thinking pull the engine, checking out the damage and probably doing an overhaul myself. Since the valve seat destroyed #4 cylinder I'm thinking get a remanufactured head with the valve seat dropping problem fixed and honing out the cylinders for some pistons of the minimum size that the cylinder walls clean up. So, should I get a good home (Lisle 15000 maybe?) and hone the cylinders to size or is their some benefit to having the cylinder bored at a machine shop? Depending on how everything else goes, I may just get a rebuilt or remanufactured engine and swap it myself, spending $2k (maybe less) on an engine is a lot better than $4k for an engine in this older car. It may be good for another 5 or 6 years if I can keep clear of the deer! Thanks! RogerN |

Thanks! RogerN If you decide to rebuild the engine yourself you are much better off bringing the block to a quality automotive machine shop and letting them clean, bore and hone it. It's not very expensive and if they are a good shop they can do a far better job than you can. |

First oversize is likely 10 thou over - typical honing (with a VERY expensive Sunnen type fixed hone) is in the order of a couple thou. Get the block bored for oversize pistons, and finish honed to proper fit. A LOT cheaper than buying and using a fixed hone. Been a mechanic since 1969. |

You manage the job by putting in writing up front what the tolerance of the cylinder bores must be and then you check them with a quality dial bore gauge before you pay. We use to have customers who checked our work like this all the time. If you don't know what you're talking about, and you don't, shut your ****ing mouth. It's not worth the small amount of money you might save to do it yourself if you don't have the right equipment. |

Thanks! RogerN If you don't believe me Roger ask someone like Bottleboob. Dollars to donuts Bottleboob agrees with what I said. It doesn't cost that much money to have a good shop clean, bore and hone a 4 cylinder. No way in hell should you try and just hone that block to size. Honing is a finishing operation that's done after boring. |

Depending on how things go I may just pick up a remanufactured engine and get the car going again a lot quicker. I'm more interested in fixing the car since I have heard the remanufactured heads have the original problem (dropping valve seats) solved. The work I do swapping the engine will probably be enough mechanical work to give me my fill for a while. Thanks! RogerN |

Thanks! RogerN Roger, Hand honing is an art that takes a long time to perfect. Cylinder finish is very important even in a **** box beater if you really want the engine to break in correctly and last. Take a look at what this race shop gets for boring and honing a 4 cylinder engine. Others are slightly lower or higher. http://www.besracing.com/machine-shop-services.html I would strongly recommend that no matter what you do that you pick up a book called: Engine Blueprinting by Rick Voegelin. It will help you understand the entire process of what it takes to properly rebuild an engine: http://www.amazon.com/Engine-Bluepri.../dp/1884089267 |

I remember reading about sealing up the cylinders and checking the CC's of each cylinder with a piece of (Plexi?)glass sealed with grease over the cylinders. Each cylinder was CC'd and the volume on the head side was also checked. Very meticulous work to get everything so perfect. I'm thinking my time might be better spent on overtime and pay to have the work done. Wouldn't mind getting an engine to rebuild and blueprint though, looks interesting. RogerN |

Get the block bored for oversize pistons, and finish honed to proper fit. A LOT cheaper than buying and using a fixed hone. Been a mechanic since 1969. At the machine shop we used a home similar to this: http://www.amazon.com/Lisle-LI15000-.../dp/B000GKIE4S We relined tubes that were around 36" long with stainless steel pipe and then honed, I don't remember for sure, around 100 thousandths out of this stainless steel bore. This took a few hours to get it honed to size but we were removing a lot of metal much more difficult than iron in around 36" of cylinder. I removed 0.020" from my motorcycle cylinder in a fairly short amount of time, maybe a half hour to 45 minutes with a lot of stopping to measure several different places. I normally didn't hone because the boss had more critical jobs to do so I stopped more often to see how fast material was being removed, checked taper, measured diameter X and Y, etc. I'm confident that I could get the bore the right size in a reasonable amount of time with a hone like the Lisle, but, like Jon said, I don't know the surface finish would be right and it looks like I can have it done cheaper than the price of the hone not considering the time plus the price for the heavy duty drill. I had a buddy tell me he polished a cylinder in a model airplane engine, the piston seized up, seems it needs them grooves for holding oil! I can see that the finish could be important for proper break-in, wear, the ability to hold oil in the "scratches". RogerN |

Depending on how everything else goes, I may just get a rebuilt or remanufactured engine and swap it myself, spending $2k (maybe less) on an engine is a lot better than $4k for an engine in this older car. It may be good for another 5 or 6 years if I can keep clear of the deer! It'll take you a month to take a 4cyl block out to 010 oversized using manual honing equipment--find a shop that sunnen cyllinder king autonatic sizing hone and jave them do it for you. As far as pistons, rings, bearings lifters and so forth, I suggest order from JC Whitney, my experience with has always been good and their prices usually come in substantially below your local parts houses--though I haven't bought anything from them in about ten years, at that time the parts were still mostly from high quality manufacturers like Clevite, Michigan Bearing and so forth. |

Honing is a finishing operation that's done after boring.

Thanks! RogerN Roger, Hand honing is an art that takes a long time to perfect. Cylinder finish is very important even in a **** box beater if you really want the engine to break in correctly and last. Take a look at what this race shop gets for boring and honing a 4 cylinder engine. Others are slightly lower or higher. http://www.besracing.com/machine-shop-services.html Thanks, I was wondering what kind of $$$ ballpark the shops charged for machining services. *Looks like I can get it bored and honed for less than I could buy the hone for. I would strongly recommend that no matter what you do that you pick up a book called: Engine Blueprinting by Rick Voegelin. It will help you understand the entire process of what it takes to properly rebuild an engine: http://www.amazon.com/Engine-Bluepri...uilding-S/dp/1... I read through a book called Engine Blueprinting years ago, might have been the same one. *I remember reading about sealing up the cylinders and checking the CC's of each cylinder with a piece of (Plexi?)glass sealed with grease over the cylinders. *Each cylinder was CC'd and the volume on the head side was also checked. *Very meticulous work to get everything so perfect. *I'm thinking my time might be better spent on overtime and pay to have the work done. *Wouldn't mind getting an engine to rebuild and blueprint though, looks interesting. RogerN "Thanks, I was wondering what kind of $$$ ballpark the shops charged for machining services. Looks like I can get it bored and honed for less than I could buy the hone for." It's still very important to put in writing up front what the tolerance of the bores must be and then for you to check them with a quality dial bore gauge. It's also important that you know what the finish of the bores should look like. You want a slight crosshatch pattern. This helps retain oil to lubricate ring faces during break in. You need a automotive engine machine shop that takes real pride in their work and is beyond anal retentive. Trust but verify everything. " I read through a book called Engine Blueprinting years ago, might have been the same one" For years it was the only book available on engine blueprinting. Most likely the same one. |

Wouldn't mind getting an engine to rebuild and blueprint though, looks interesting. Look on craigslist or at a wrecking yard for one that was pulled out of a totalled vehicle; one that supposedly already runs fine, and rebuild it... --if the oil is charcoal black, don't buy it but if it's a dark amber it's probably okay, this means that somebody had at least been changing the oil every so often. |

My own experience in engine rebuilding is that it is generally cheaper to take the stripped block to a shop top have the work done. -- Cheers, John B. |

If you know what to look for and how to manage the job a boring machine like a Rottler and a Sunnen CK-10 can do a much better job. There is no real money to be saved doing it yourself. Particularly at the cost of a Sunnen rigid hone. And the minimum 2 sets of stones required to do the job properly. |

No way in hell should you try and just hone that block to size. Honing is a finishing operation that's done after boring. And he NEEDS to do all 4, not just the damaged cyl unless he wants to turn the engine into a Whacker plate tamper. |

I have many that have never been used - and many more that have been used once or twice. |

Instead of spending $4k on having a mechanic replace the engine with a Jasper remanufactured engine, I'm considering getting something else but working on the Escort. So I'm thinking pull the engine, checking out the damage and probably doing an overhaul myself. Since the valve seat destroyed #4 cylinder I'm thinking get a remanufactured head with the valve seat dropping problem fixed and honing out the cylinders for some pistons of the minimum size that the cylinder walls clean up. So, should I get a good home (Lisle 15000 maybe?) and hone the cylinders to size or is their some benefit to having the cylinder bored at a machine shop? Depending on how everything else goes, I may just get a rebuilt or remanufactured engine and swap it myself, spending $2k (maybe less) on an engine is a lot better than $4k for an engine in this older car. It may be good for another 5 or 6 years if I can keep clear of the deer! Thanks! RogerN If you decide to rebuild the engine yourself you are much better off bringing the block to a quality automotive machine shop and letting them clean, bore and hone it. It's not very expensive and if they are a good shop they can do a far better job than you can. And you're a dick . Roger , get your hands on a rigid Sunnen hone , one that has the rack type feed you mentioned above . I've bored several Harley cylinders with mine with great results . You've got the advantage of a lump of metal that you won't have to bolt into a fixture to hold it still ... plus the fact that you can hone to a fit that meets *YOUR* standards instead of whatever mood the boring machine guy happens to be in on that day . I'm bettin' that he ain't going to take the time to fit your pistons individually to .00075" . I will agree with Yonnie that you might want to have a shop clean it in their dip tank , unless you want to do like I did with my wife's car motor and take it to the car wash . BTW , from your comments above you apparently have the skills to do this job yourself ... and a 50/50 mix of diesel/kero and ATF makes a great honing fluid . And don't forget the post-hone washout !! -- Snag **** you asshole. I'm bored and honed more blocks than you ever will in a commercial automotive machine shop. If you know what to look for and how to manage the job a boring machine like a Rottler and a Sunnen CK-10 can do a much better job. There is no real money to be saved doing it yourself. Particularly at the cost of a Sunnen rigid hone. And the minimum 2 sets of stones required to do the job properly. What can I say ? I bought TWO hones at a pawn shop with several sets of stones INCLUDING THREE SETS OF BRAND NEW STONES for fifty bucks . Swapped one hone I kept the best one for some Harley parts . I kept the new stones .... OK , so I got lucky . -- Snag Still haven't used the new 400 grit stones ... |

Total cost was less than $400 Something of a fluke...but.....Grin I long term loaned them to a buddy who runs an engine rebuilding shop. Now I dont pay to have an engine rebuilt.
