Today on Motorz, Chris is taking our small-block to the machine shop Presented by AMP Research. In our previous engine rebuild episode, we showed you how to tear down a Chevy 350 all the way to the block .Well the next step is take it to a machine shop so that it can be checked for cracks and cleaned up before we can rebuild the bottom end using products from Mahle Motorsports and Eagle Specialiy Products. Britt Bostick the owner of the owner of NewTech Engine Systems in Ramona California, did an excellent job machining our block. He took it from a boat anchor to a usable block that with just a little bit of paint will look like new. Now lets head over to NewTech to see what it took to get our block to look like this. Britt’s shop NewTech Engine Systems is located in Ramona California, he has a ton of specialized equipment that most of us just don’t have access too. So when it comes time to machine your block you need to take it to a shop like NewTech, now since Bret has a full service engine building shop he can build anything from a daily driver to a full blown race motor. Now we could also have him assemble the motor for us but that would take all the fun out of it. Well Britt, thanks for letting us into your machine shop, everybody wants to know the process of machining a block so what’s the general overview of what we’re going to do today. [Britt] Ok, well, first off we’re working with a Chevy 350, you guys have already stripped it down so it’s going to go into the jet-wash tank, after it comes out of the dish washer, then we’ll buff it and get it all clean. [Chris] Using a camshaft bearing tool, Britt removes all the bearings in our block, we’ll use the same tool later to install some new ones then he removes all the freeze plugs, using a punch, hammer, and some pliers next step is to magnaflux the block to make sure there aren’t any cracks. [Britt] We’re going to mag it with this magnaflux mag, and this powder is basically blow the excess off and you look for cracks this powder is consists of cast iron, talcum powder and it’s got a color in it so you can see it do the lifter bores a lot of these later model 350 Chevy’s they lighten up the casting so they have a bad habit of cracking up in the lifter bores Well, that’s that, you guys lucked out. No cracks. [Chris] We’re going to take a quick break while Britt gets our block ready for line honing. [Chris] Well you’ve got our block setup in your line hone machine, what’s going to happen here? [Britt] We’re going to dress the main saddles, get all the burrs off them, the other thing I like to do is go along and ease the edge here, that way when we’re done when it goes on assembly, you’re not peeling metal when you push the bearing in. We’re going to go over in a bit and cut the caps, and then we’ll rough line hone it and we’ll get it to the low side of the spec and then at that point we’ll measure up the crank and we’ll put a bearing in it and we’ll physically measure and check the clearance. [Chris] Britt uses a belt sander to deburr and champher the main caps this will make it easier to install and remove the bearings during the assembly process then he uses a cap and rod reconditioning machine to square the main caps in preperation for line honing. [Britt] Now that we’ve cut the caps and we’ve filed these mating surface, we’re going to go back and file the edge here. [Chris] In preparation for line honing, Britt puts the all the caps back on in a specific order, adds some bolt lube, puts the bolts back in, tightens them down, then torques them down to spec. Britt uses a setting fixture for the Sunnen dial-bore gauge, setting it on a low side, he’ll line hone our block to that setting. Now once that’s done we’ll put the bearings in, use a micrometer to measure the crank size, set the dial bore gauge again and then verify our clearance and make adjustments as necessary [Britt] So we’re at minus 3, minus 3 and half, minus 3 minus 3 and about 2/10’s, minus 3 and this was a minus 2 but we’re not going to get excited about that because that cap is wider and it cuts slower [Britt] This one is half, second one is half a thou, half a thou half a thou, about 4/10ths [Chris] a micrometer or a mic, is a precise measuring device when you need to measure something down to 1 thousandths of an inch or smaller, Now we’ve got our crank from Eagle Specialty Products, what do we need to do to it? [Britt] For right now we’re going to mic it, because we want to get the size of it, put a bearing in that block and then set the dial bore gauge to the size of the crank and then that way we’ll get an accurate on what the oil clearances will be but since we’re here, we’re going to go ahead and mic the main and the rod journals and record those on a build spec sheet for later references because we’ll need the rod sizes when we compare the oil clearance on the rods, when we get to that part. Now we got the gauge set and bearings in there and the caps torqued up, gauge is set to the size of the crank we’ll just gauge this hound dog and see what we got for clearance. All right, we checked out clearances with a standard bearing in here, it so happens the crankshaft, a lot of these manufacturers will put the performance cranks on the low side so we ended up with 2 and a half clearance, and since you’re going to run synthetic oil we want a little less than that, so we put some 1 under bearings in here and we’re going to check that now. And we in fact have 1 7/10ths clearance, so we’re going to call it a day [Chris] All right Britt, we’re done line honing the block and we’re standing in front of the block master, what is this thing going to do to our engine? [Britt] We’ve got a fixture that BHJ makes, and we’re going fixture is all up, put it in there and when we’re done it’ll lines up the cam and the mains and the deck surface 90 degrees to each other and then at a 45 to the centerline of the block you’ll find these blocks will be rolled one way or the other and they’ll be off end for end, so this makes all the cylinders will end up being the same size when we’re done. [Chris when we’re done. [Chris] When we’re done squaring up our block in the Block Master we’re going to move onto our cylinders. So hang in there, we’ll be right back with more Motorz [Chris] We need to use the micrometer to verify the diameters of each piston before we hone the cylinders, that way we’ll make sure we end up with properly sized cylinders. We’ll bolt on a torque plate to simulate the stress that the head will put on the block and then finish honing our cylinders [Chris [Chris] Next, Britt cleans out the lifter bores so that the lifters are free of rust and debris then to prevent damaging the skrits of our new Mahle Motorsports pistons Britt chamfers both the top and bottom of each cylinder then finally he chamfers the distributor hole which makes our block more accomodating to an aftermarket distributor with an o-ring Now that our block has been machined, the next step is to test fit our brand new crank from Eagle Speciality Products, but before we do that we have to pop our caps off, put everything back in the jet washer and get that thing clean again, after adding some assembly lube we can install our crank and our caps and then take one of the pistons and put it in each cylinder to make sure we don’t have any clearance issues, our cap bolts did clear, but it was a little bit too close for comfort, so Britt took a sharpie and marked the area and then opened it up a little bit while the maching of our block is done, we’re not, so hang in there for Partz, coming up next Partz is brought to you by the Sears Blue Tool Crew We have just about every size standard and metric Craftsman socket in our shop so that we can quickly finish our project and meet our deadlines, now we’ve got the standard chrome sockets as well as impact sockets for our air tools in both standard and deep sizes. Most of the time that’s all we need, but occasionally we encounter a fasterner like this guy where our deep sockets just aren’t deep enough. In tight situations like this quite often the best tool is an open end box wrench, but as you probably already know, unless the sitation is ideal, which it rarely is, you can never get the leverage you need and the open end wrench just keeps wanting to slip off. That’s why Craftsman came out with this max access socket ratchet and drive tool system there isn’t a bolt in the world that is too long for this innovative tool due to its pass-through system, which elminates the need for deep sockets, plus the max access system provides exceptional fastener clearance for long bolts and it fits in spaces where traditional sockets and ratchets can’t included in the system are two low-profile pass-through ratchets that are 40% stronger then traditional ratchet designs, only have a 5 degree ratcheting arc which allows you to turn a fastener in tight spaces without a huge swing just like the standard ratchet versions these feel great in your hands thanks to the ergonomic paint handle design, also included with the system are extensions and a adapters for both 3/8″ and 1/4″ sockets so you can even use these ratchets with your regular sockets, pack it all up to go with the included plastic carrying case and have a piece of mind that if one breaks you can replace it thanks to Craftsmans lifetime warranty.

You probbly already know about vehicle programmers that plug into your OBDII port they quickly increase the performance of your vehicle, conduct tests and more. SCT has been making them for years, like their SF3, X3, or even their touch screen Extreme. SCT’s automotive programmers can increase your vehicles horsepower, torque and throttle response and a whole lot more all by optimizing your vehicles engine management computer. But what if you’ve already got a iPhone, an iPod touch, or an iPad. Now if you’re like me you’re wondering why the heck we can’t use the mobile devices that we’re already carrying around to tweak our rides brain. But the only way to interface with you cars computer is via the OBDII port, which is located under the dash in 1996 and newer vehicle. So how do we get this to talk with this. Well our good friends over at SCT figured it all out by creating the first bluetooth OBDII interface of its kind that communicates with your iOS device. It’s called the iTSX and not only will it give your vehicle more perfromance in 15 minutes without getting your hands dirty or even cracking open the hood, but it can also monitor your vehicles engine parameters, read and clear diagnostic trouble code and measure your vehicles performance by using the built in performance calculator all wirelessly. It includes a variety of configurable on-screen virtual gauges and layouts and for parents with younger drivers the iTSX also has the ability to set a vehicle speed limiter for increase safety Yeah, my daughter is going to just love me for that one [female] Dad! [Chris] It’s currently available for 1996 on up, Ford and GM gas and diesel vehicles, this is by far one of the coolest and most useful gadgets I’ve seen in a long time. We’re already having a lot of fun with it the iTSX app is available right now in the Apple AppStore and you can find out more about the iTSX hardware by clicking the Partz button at our website, motorz.tv.

Next up is Tyler who writes – Hey Chris, I love the show and watch it all the time. I own a used 1997 Chevy S10 and it needs a lot of work. ANy advice for a DIYer like myself? And do you know of a good place where I can get a cheap OBDII reader? [Chris] Well Tyler, of course in additional to Motorz you can check out other shows on television and online, but the best thing for you to do is to check out a Chevy S10 enthusiast website, there are a lot of great people at those forums and they can help you out with everything you’re trying to do, because they’ve probably already done it before as far as your OBDII reader, head over to Sears.com/tools or check out your local Sears store, because last time I was there they had a ton of options and check their Facebook and Twitter accounts as well, because they often have discounts Iggy wrote in and said – How should I install an oversized drain plug in a 1989 302 HO motor? I started to slowly turn it into the oil drain pan, but there was too much resistance. This is a stock double hump oil pan with two drain holes [Chris] Well Iggy, you should try to use a thread tap to try and repair those threads to you can use a factory sized plug, now if those threads are so far gone you’re going to have to use the thread tap to create some new threads, then get a new, slightly larger plug for it. and finally Chris asks – I’ve got a 2003 Kia Sedona with 80,000 kms and the crankshaft needs to be replaced at Kia. They asked me for $2,500. Do you think it’s worth it or buy another car? If so which minivan would you recommend? Thanks for your help! [Chris] Well Chris, you should check out what else may be wrong with your Kia Sedona, as well as the status of your pocketbook to make that decision on your own, but if you do move ahead with a new minivan, check out the new 2012 Dodge Caravan RT, and the copperhead pearl coat. Now that’s a swagger wagon!
