Build Diary, Part 2:---12/20/08---I actually started removing the engine a week or two ago, but finished it up today. I got the engine out, separated the trans from the block, and removed alot of little things. Got the clutch and flywheel off the block, and about ready to bolt the engine to my stand. Tomarrow I will try and work around the rain and get the head removed and the block inside for tear down.Here is the car sitting under the engine lift frame, opened up to dry it out. I left the windows open for the last 2 or 3 weeks and we have had some pretty hard rain in that time. So it got soaked. Good thing I have new Katzkin leather seats and door panels on their way here. Interior is a bit dirty. Hasnt been driven in 4 or 5 months, so I guess it gets like that when it sits.Here is the engine in all of its non working glory:Inside of the head is pretty clean, mix of cleaning it last time, and running good synthetic oil. While all of this mess goes on, feet away sit skeletal remains of my Miata's dead relatives. I hope this isnt an omen or bad luck.I will hopefully have more pictures tomarrow, and will have time to update.---12/25/08---Got a bit done since last time, just havent felt like updating. Got everything apart, block stripped, brought it to the shop and had it machined and hot tanked. Now its back in my hands spotless, about to receive a coat of barbecue black paint, and then be rebuilt. Everything will start once I get my new torque wrenches and a bore gauge to check my bore since the shop didnt. I got the pistons out and found the oil control rings on all 4 pistons stuck compressed, so that might explain some of my problems. I will try and post the pictures today sometime, but right now its 1AM and Im drunk and tired from christmas eve party.---12/26/08---Nothing more to report for christmas day. Got some good gifts for my car, and gifts to help me work on my car. New set of tools, and an air compressor with some air tools.Here are some more pictures from the last week or wrenching on the engine:Oil pan off, along with windage tray and pickup tube. Looks pretty clean for a 110k mile engine. Another of the engine stand "rig".Trunk full of parts and a passanger side of a BP block.Once shiney and clean ports, intake side. Block and head from exhaust side.Rear of the engine with a bucket full of parts. I keep all of the smaller, more dirt sensitive parts in a large bucket that has a screw on lid with a gasket.Partly stripped block, exhaust side. Next is a freshly pulled piston, #4, look at the oil control ring... Stuck!Another shot of same piston, and a shot of the average bearing wear in this engine. Bearings are in VERY good shape, as well as the crankshaft.Box-o-pistons, and a rodless crank in block.Block stripped bare, except for that one copper washer on the oil squirter I missed.The block is now cleaned and decked, and will get hones soon, and then I shall start assembly, after I measure some things. I will paint the block tomarrow and post some pics of the final bare block.---12/26/08---Got some done. Block is cleaned and painted, cylinders honed, crank installed and one piston in. I had to go back and take the main cap bolts back out to install the crank scraper I forgot. Here are a list of my clearances and Mazda factory specs:MazdaCrankshaft endplay: Standard .0032-.0111 Limit .012Crankshaft oil clearance: Standard .0007-.0014 Limit .004MineCrankshaft endplay: .008Crankshaft oil clearance: ~.00175So my oil clearance is out of ideal specs, but just barely, and still well within maximum specs, so Im running with it.I also got the crank scraper in and everything went in without a hassle. I-J calls for between .030 and .060 clearance, my lowest was .025 and most was .032, so perfect!Here are some pics:Things are looking good so far. I will clean the other 3 pistons tomarrow and install them. That should be it for my bottom end, then I will move onto head part 2, which shouldnt be much work. I will probably strip it, have it tanked, machined another .002-.005 to have the few little flaws removed, then install it again and hope for the best on first start up. Head work should go easier this time since I bought a nifty $100 valve springs/keepr tool. No more grease and pick to fish the keepers in and out.---12/28/08---Bottom end rotating assembly complete! Now all I have to do is wait for my 3/8'' NPT bung to arrive from Jegs, and weld it into the pan for the oil return (will be plugged till the turbo comes). Then deal with the windage tray, oil pick-up, oil pump, water pump, brackets, then what ever Im going to do with the head, and its time to put it back in the car. I might actually be able to drop it back in this weekend, but Im not going to rush it, so probably next week or weekend.---12/30/08---Since the block is all but done, I brought the head in from outside where it has lived for the last 2 weeks. It was a bit wet and the oil left in it had turned to milkshake, but its going to get washed anyway, so not a big deal. I got it all the way stripped, except for #2-#4's valves, springs, retainers and keepers. Should finish it off tomarrow sometime, then clean it Thursday when Im off, and piece it back together maybe Thursday and Friday, then hopefully bolt the head back to the block, and drop it in this weekend.---01/02/09---Final stuff being worked out. Head and oil pan at the machine shop. Head is getting hot tanked, dowel pulled and another .002'' off, and the oil pan is getting drilled, and the bung welded in for the turbo return. I also ordered 2 dowels from Trussville Mazda. $2.45 each (2), but wont be here till Tuesday or Wednesday... great. Machine work will also be done around Tuesday, so not a big deal. Maybe by next weekend I will at least have the engine back together and in the car. Might even get it running if all goes smoothly.---01/06/09---Well, yet again a bit of a delay. I got my oil pan and head back, but the machine shop let me know that I apparently forgot to remove the lower valve spring shims. The only found 15 when putting the head on the machine, so somewhere between here and there is a tiny, thin shim. I guess thats another special order part I will have to get from Trussville Mazda. That will probably take another 4-6 days. I may get lucky and they will have one in stock, but I doubt many people come in looking for them.Either way, oil pan back, shop did a great job with the welding. A tiny bit of burn through, but I dont really care. Head is also spotless, and ready for assembly after I find that damn shim. So now I wait on a shim, 2 dowels and some head studs. Damn little parts holding me up!Picture time:Ports dont look as good as I remember. I guess the hot tank and chemicals showed the worst of my "porting". Inner port looks bad, outer area looks fine. I guess I will clean it up a bit while Im waiting.New exhaust side hardware from MiataRoadster. Looks great and shouldnt rust, since its all copper and zinc plated.---01/11/09---Progress is slow, but Im not complaining. Its been raining and a muddy mess, and I havent had time outside of work this week to do much more than piddle work. Engine as a whole is pretty much done, except for a few minor things like brackets and hoses. Its still inside the house though, so its going to be fun to go down 2 sets of stairs with a fully assembled engine. Here is how it sits as of tonight.I could have done a better job at cleaning up some of the parts, but with the weather lately, I wouldnt have had any time or good enough weather to do anything about it. Valve cover will be repainted though. It used to look good but all of this engine work over the last few months has taken its toll on the paint.---01/12/09---A bit further yet. Timing belt on with covers. Engine mounts on, and a/c bracket. Still have a minor pile of parts left, but they are mostly from the intake manifold which wont go on until the engine is outside.Valve cover needs new paint badly. I may just do a single touch up coat of the wrinkle over the existing wrinkle finish, then a coat or two of barbecue black high temp paint over that. I really dont want all of the hassle of stripping the whole cover, big mess and alot of time. Not much more I can do for the next 2 weeks, since this weekend my engine carry helper is going to be out of town, and this and next week I work late shift, so no time. I guess it will give me time to further clean parts and make it look a little better.---01/18/09---Nothing really going on this weekend. All I got done was painting the valve cover, and it was done kind of rushed. BBQ High temp paint over the old wrinkle finish. I also bolted on the RB header for fun. Next weekend should be the first start!---01/18/09---Got some done yesterday. Engine in and partly hooked up. Should get it done today.---01/28/09---DONE!!! As of 01/25/09, my engine has been fully rebuilt, and runs very well (so far, after 100 miles). This page is complete.
