Well i have to say fixing all 3 at the same time is better then doing them at 3 different times.
^ Very true. haha.
Actually I miswrote that, it was a coolant hose at the back of the engine. Looks like a mofo to change, but easier with the valve cover off.
Anyone know what the coolant hose at the back of the engine on the intake side is called? it's not one of the heater hoses, it's on the other side. Looks like it's clamped between two pipes, or nipples off the engine. About .5 to .75 in diameter and maybe a couple inches long if I remember correctly. Never seen it mentioned of before. I'll have to take a better look at it after we get it towed home.
One of the lines that goes to the intake manifold? Or it's just in that area?
The only diagrams I have are of 1.6s, and there's nothing really like what you're saying on those. Oil cooler line? It's been forever since I've seen a stock setup, so I could be way off on that one...
Does anyone have a link to a decent parts diagram that might show that area? I cant find it in any of the coolant system diagrams, and the dealer can't find it either. My car is in a random parking lot at the moment but i'll grab a photo when I get to it.
If you know the shape of the hose, you can find it here and get the parts number:

What the F is this?? I think i've found the culprit..

Over an inch of play, but the bolt is still tight. Something's not right here. The bolt looks to be rounded off as well. Wonder if this car's been to Miata Technologies in a former life? :) Double checked and the TB is still busted.
Steven, that's the right hose, thanks!
Ouch, that's not muy bueno at all. I can't tell if it's just harmonic balancer or not, mine did go out, but it never came loose like that. It would just slip and i couldn't adjust the timing.
Broken crank shaft?
EDIT - Would a broken 'key' make it loose like that? (dunno)
It gets worse...
The bolt was actually not tight, just rusty. Almost hand tight. I pulled it off to dig further.
The key has been missing for some time looks like judging by the dust inside the channel.

Does everyone see what I see? I had trouble getting a good photo in this light. I'm in unfamiliar territory here...someone tell me how bad this is... I read on M.net things like this could result in replacing the crankshaft(engine) Is this damage light enough to be maybe repairable, or is it finally time for a 99 swap?
Better photo. In case you're wondering... the timing belt is fine.

Does the crank bolt thread back in? Is the key way damaged?
Give me a call after 10am at TDR and I'll see if I can offer suggestions. We have repaired a few damaged key ways.
We also have all hoses and hardware in stock.
The crank bolt threaded back in just fine. The keyway is damaged on the crank, but the timing gear looks ok.
Obviously it's time for an LSx.
How badly is the keyway damaged??

You can probably clean up the keyways and loctite a new key in place.
Where are you in Euless? I have to run over there in the next couple of nights. I might be able to stop by if you'd like. When I took mine apart it had some of that "dust" present, and that main bolt was loose too. I used loctite on the key and the bolt and put it back together. So far so good.
Can you see the photos? They're pretty indicative of the damage. I'd get better photos but a monsoon just moved in.Quote:

Jake, I might take you up on that offer. I want to see if it's minimal enough that locktite would fix it reliably. I don't want another failure while autocrossing or something. What days are you in Euless? I'm close to 183 and main.
Well on a positive note, your clutch might be perfectly ok
I hope it's a simple fix! Sorry to hear this.
I'm with Rob, this could've easily been the culprit for your issues.
You guys could be right. Also it's probably a good thing it didn't fail on course at WOT. Seems like it's a common problem associated with botched timing belt jobs..improper torque.
I think I got lucky judging by some of the photos I've seen. I'll have to bust it completely down to make sure, but I think the locktite fix is in order. Anyone have a harmonic balancer and the 'cog' (timing gear) laying around? Mine may be reusable, but I think i'd rather replace them. The bolt i'll get new.
I wouldn't even consider reusing that gear (I'm in the camp of replacing when you do a timing belt though...stupid Z habits).
Same with the belt, but I can't imagine you'd reuse that if you have a new one waiting already.
I'll probably go that direction tonight. Let me know if you'd like for me to stop by.
When was the last time you changed the water pump? you are practically there, it may be something else to consider.
i know i'll be checking mine this weekend just for fun..
I have a water pupm ready to go in. After I compete the damage assesment I plan to overhaul as much as I can while I'm in thereJake. Ill just be tearing down more tonight so swing my if you're in the area. Ill pm you my address.
Can someone look at these photos? Looks like i'm one tooth off on the intake cam.I count 20 teeth between marks and the intake is off just a hair. I don't see how it could have jumped a tooth given the belt is tight as a drum and the car has been running perfectly fine before monday.
Actually come to think of it the idle went haywire and the car seemed to rocket off the light with minimal gas right before it died. But if the failure existed at the crank, how did the intake(or exhaust) cam jump a tooth? Wouldn't it be more logical that the crank be off? I dunno, just thinking outloud. Anyway, the photos...

I've seen worse locktite fixes on Miata.net, so locktite it is. If anyone has experience with this fix that is available thursday, that's when i'll be taking off work to put this mess back together.
You sure the 1.8l should have 20 teeth between the cams? I know a 1.6l is 19 teeth. Pretty sure the 1.8 is the same..it's been awhile though, so I would triple check that online.
Also, did you rotate the crank after you lined everything up? You need to get it all lined up, then rotate it all the way around again to make sure everything is still lined up, then rotate more for the tensioner part.
^ That's what I was saying (well maybe I didn't say it well, I had greasy fingers) I count 20 teeth, unless i'm counting wrong. From what I read there's supposed to be 19 teeth. This was the old belt before removing it, and there are 20 teeth, looks like it jumped a tooth when things went bad.
I couldn't rotate anything with the crank because the crank was free spinning inside the timing gear without the key present. I just removed the belt, and gear. I'll make sure everything is at TDC when installing the new belt. For now I still have to pull the cam gears to get to the WP.
LOL...yeah, completely forgot you're still just tearing down. For some bone headed reason I thought you put the belt back on and had 20 teeth. Sorry..it's early.
not to get away from the timing belt problems. I had a coolant leak like 3 weeks ago and I think it is the same hose you have leaking. Mine came out of the rear of the engine and ran under the intake. I couldn't fallow it after that. It was leaking at the coupling holding it to the back of the engine so I just pulled it off and cut it clean, added a straight through and ran another hose to the rear of the engine from there. It's working so far. I needed a quick fix and I know that the hose is old and might start leaking again but if that happens I will deal with it.
WTH... what else is going to go wrong with this project.

Cam pulley bolt. I set the torque to ~40lbs per miata.net. Exhaust bolt went on fine. Intake bolt, something never felt right, never got even close to tight, then felt really loose all the sudden. I immediately stopped and backed it out slowly. Guess i'm lucky really, but now i'm sourcing a replacement. I'm going to replace both in case the other one is damaged as well.
Could over torquing on a previous job do this? I don't think I ever came close to 40lbs during this whole job.
???
Yep.... Make sure you double check everything.Quote:

Has anyone ever actually changed this blasted thing, because Im not convinced it's ever been done on an installed engine in the history of miata wrenching. I'm about to pull the intake manifold unless someone can tell me it's possible otherwise.
I have two of the super long needle nose plyers, one is curved at the end. After an hour I've only been able to mangle the clip and tear the neck of the hose off at the clip. anyone have experience with this cursed thing?
Yep been there done that... Move the clip out of the way then just cut the hose off the bib.
Then throw it across the yard it will make you feel better!
Success!! Man those hoses were a PITA. Yes I threw them both across the yard.
