Joe's Answer: The "NBeater"

Recommended Posts

Indeed! Glad you saved it bud. And yes, clearly your wife loves you very much.

 

Also also, dude that's some awesome memory and drawing..and evidently you keep your tools really organized. I have to hunt every time I want to find a tool...i suck at organization

It was lucky that I had just cleaned everything up, so that they were in the right spots! I'm usually "semi organized". I track tools like gazelle in the wild. Things periodically return to the watering hole (toolbox), but I know where they were last seen in the mean time. 

This weekend I changed the oil, replaced the alternator belt and accessory belt, and swapped the mismatched worn out, cobbled together front sway bar endlinks with some fresh FM links. Less clunk/ bang leaving the driveway 😉

I would have installed a mazda replacement plastic under tray (car came without one) as well to help ensure cooling airflow, but several of the mount points were found to be compromised...bolts broken off in them, tabs bent to hell, etc. That'll be a quick project to make new tabs, and zip them on with the mig gun. Just need the time 😞

The engine removal process has been smoother than expected for a 20 yo car...I suspect most of these bolt have been broken loose in the past few years lol! 

It's all but ready to come out. Just need to confirm it's all disconnected , attach the picker, spin the mount nuts off and lift...

Glad I'm going over the thing out of the car. Itll be easier to find gems like this left by the previous owners. I think the connector was supposed to stay away from heat...think it was laying on the egr tube 😲😬

Best first Fathers day ever! 

New water pump, coolant reroute kit, cam seals, timing belt and tensioner, oil pump, and front /rear crank seals got in today. Tomorrow, new clutch, and sealing the oil pan properly. And finding a nut to hold the oil pick up to the wind age tray. The last person in the oil pan thought it was unnecessary apparently..but thought that 2 full tubes of rtv were needed to seal basically everything  lol...

The NBeater hath been reborn. It shall henceforth be known as "Gateway Drug". After it's reliability makeover, it will be used to entice co workers into coming to try track driving...the first one is free...

During the past 4 days it received in no particular order a few new parts:

Clutch Kit, clutch slave and master cylinder with stainless line, a "gently used" 5spd transmission from craigslist, shifter rebuild, motor mounts, water pump, oil pump, timing belt, cam seals, front and rear crank seals, re-sealed the oil pan, new egr tube (old one was cracked), new exhaust manifold gasket, supermiata coolant reroute kit, supermiata crossflow radiator, new coolant hoses, FM rebuildable driveshaft, new brake booster vacuum hoses, and a coolshirt system. 

Car feels fantastic now (my hands and back are a different story !)  Only major maintenance left is to pull the cams at some point measure the existing shims and order new ones for the 13/16 that have clearance which are out of spec by a few thousandths. And perhaps throw fresh dampers and streetable springs on it - 700#F / 325# R  spec miata rates are getting old on the street. I have a pretty new feeling, '99 salvage title Miata, that I'm not concerned about cosmetically. Exactly what I was shooting for 😉20190618_154805.thumb.jpg.5e1f9a7eaf7ccb1c5299d0dc5fa0eac2.jpg

Success! Ran great temps all weekend with my buddy Mark Churchill at the helm. Coolshirt worked great. Coming from a Corvette Grand Sport, his only question was where all the horsepower went haha!

Tell him the name of the game is to increase his min speed.  Driving a Miata will make him faster in a Vette.

Any data Joe?  I’d be interested in those min speed references.  Here’s mine from the weekend vs a slightly faster time in the other direction back in April 200TW RE71R:

Sadly, no data from the Miata. I have an Aim, but it was in my BRZ, and I forgot to offer it up to Mark in the Miata. My wife has expressed interest in taking the Miata to be her track car (and trade her WRX for a mom-mobile), so it'll be out again no doubt.

So it turns out that the disconcerting thumping that I have lived with for the past month WAS the diff hitting the underside of the car when going over bumps of just the right size at just the right speed...The noise sounded like something heavy hitting the underside of the car somewhere with some oomphf!

It had been getting progressively worse since I had the motor out and put it back, so I spent Saturday night and Sunday morning pulling the diff, knocking out the old bushing remains from the housing and slapping in some urethane Energy Suspension replacements. I suspected that the diff was hitting the underside of the car. When I got the diff down out of the car, I was 95 % sure my guess diagnosis was correct. There were a few witness marks where the diff had rubbed on the sheet metal, and some shiny spots on the top of the diff. The old bushings had broken down quite a bit, and I think jacking the car up by the diff as much as I have since I got it, just forced their hand. One was ripped 1/2 way through both of it's rubber "arms", and was crumbly. 

New bushings in, and the car is great again! There's one spot on the way to work about a mile form my house that would both cause the noise every time I drove over it. A right hand sweeping turn that has a nasty bump at entry and another about halfway through, that served as my test bed. I hit it 5 times in a row - just making laps over it progressively faster each time, giggling to myself maniacally. No more thump thump thump sound as the diff bounced off the underside of the car ahaha!  

There are two steel bushing retainer type plates that the Energy Suspension kit requires you to strip of their factory rubber parts and re-use. The look from my next door neighbor  was priceless when they waved to me - Sitting on a bucket in the driveway, old MIG gloves on, ratty tshirt, ratty old workout shorts, propane torch in one hand, vice grips holding the steel bushing being de-rubbered in the other. Full-on caustic smoke motorsports smores being made and me beaming through it all - happy as a lark with the knowledge that my commute will likely now be 50% less likely to kill me when the diff drops out :)

Houston, we have a problem. The car runs well, but appears to be losing water somewhere. I cant find any leaks from hose connections, the coolant re-route additions, the coolant tank doesn't appear to have any cracks. This leaves one place where the water could be going...and I did get it hot when it lost alternator / water pump belt tension back in April. Im worried the head gasket was damaged, or the head warped some? There's no leak into the combustion chamber bad enough to produce white smoke, but it's mostly distilled water / water wetter in the system anyway. The splash of glycol was for leak detection through smell - might not be enough to produce white smoke.

Changed the oil when fashioning an oil cooler setup yesterday, and it didn't look like there was water in it.

I have one of those combustion gas detection kits for cooling systems on the way, If it turns out there is a head gasket leak, I assume the heating incident did it, and it's worth getting the head inspected / squared up while it's out. Any recommendations for a Machine Shop in Houston that does good work?

I have a 1.8 HG if you want it.  Had ordered it when I planned to pull the head, but didn’t once it was the lifters.

I also have a NB1 head in great condition should things turn south. Plan is to take full inventory next weekend, I may have more than that....

I saw on the spreadsheet you had a couple for sale ;)  Are either/Both surfaced and true, ready to install?

One is an X-Factor non-SM-legal head with an MSM intake cam. It was/is amazing but have to determine whether it sustained damage in the big wreck at Barber. 90% chance it's still good.

The other is an OEM NB1 head ready for install. Unknown mileage but good condition.

Love the brotherhood here! Sorry to hear about more issues Joe. Any plans to run in the Dallas area, or COTA before the year is over? If you drive the beater, I want to sit in it for a laugh 🙂

The track crowd is strong with the camaraderie vibes - brotherhood is the right word choice for sure.  

Sit in it? Hell dude, you can drive the rolling riot of hillarity, pending  it surviving my impending potential head gasket swap 😉. Just tightened up all the coolant hoses, checked for water leaking anywhere, didnt see any. But i also pulled the spark plugs, and they all look identical / perfect, so im not sure if water is getting in a cylinder or not...the car feels strong as it ever has to me. The coolant test kit to see if combustion gasses are getting into the system will be here tomorrow. Hopefully more definitive results from that. If not there are a few other tests i have read about to help exonerate/implicate  the head gasket 

I'll for sure be up there at MSRC / ECR again before years end buddy, I'll let ya know!

BAM! Block tester kit detected NO COMBUSTION GASES IN THE COOLANT! That plus the spark plug condition leads me to believe that the head gasket is in all likelyhood still good 🙂

Had to drain some coolant from the radiator to use the test kit. Upon refilling the coolant, when I touched the bleeder screw on the coolant reroute at the back of the head and it was pretty loose. Might have been the culprit right there...locked it down pretty good this time, hopefully coolant loss problems are solved !
