Was - Did I kill my starter, ...? - Now - Please help me with my timing belt...
 
Hi after I redid my coolant reroute and changed fluids I stated my car today. Started well, then stumbled and won't start again. The loose sensor wire of my oil temp gauge might have hit my starter.

Now the car sounds a bit strange - like a wirring sound and doesn't start. Did I kill my starter or maybe?
After a while of cranking some white smoke came out of the intake... And I can smell fuel...

Maybe I give the starter a small push with the car in gear or hit the starter with a hammer...

I will also try to reload my firmware on the MS3 tonight and reload my MSQ. I think I might have corrupted the firmware...

Any other ideas?

curly 03-22-2012 09:58 AM

Shouldn't of killed it. I grounded my socket wrench directly to the power bolt a number of times, that's always the point in engine removal that I remember to disconnect the battery.

Mine's been fine, 120,000 miles and still starting strong.

rharris19 03-22-2012 10:13 AM

If the car is cranking then your starter is fine. I would look elsewhere.

Zaphod 03-22-2012 02:59 PM

I am a bit lost now here...

As I wrote above - The car started at the first try, ran for some second and now nothing. I cannot get reasonable RPM readings in TS,

This is how the car sounds, when I try to start:



I suspect something I can't really believe - could the cam belt be gone?
I couldn't see a thing because of the covers and the darkness...

Please help me out.

I will try to reflash the firmware tomorrow anyway... And I will swap my DIYPNP and see if it starts...

curly 03-22-2012 03:07 PM

I fucked up your tube link, but it didn't work to begin with anyways. ----.

Zaphod 03-22-2012 03:10 PM

Should be working now...

Reverant 03-22-2012 03:20 PM

Looks like no cam signal? What does the composite logger report?

Zaphod 03-22-2012 03:36 PM

Gonna look tomorrow... After the reflash.

hornetball 03-22-2012 06:47 PM

If the engine is turning over really fast, it means no compression. I stongly suspect you've broken your timing belt. Pull your valve cover. It will tell the tale.

Fortunately, the Miata engine is non-interference, so this is actually not a big deal.

RattleTrap 03-22-2012 08:22 PM

No compression, no valvetrain friction. No cam-drive!
BTW, that 'white smoke' is fuel. No smoking...

Zaphod 03-23-2012 02:08 AM

I am a non-smoker - so don't be afraid... ;)

I also suspect the cam-belt - the engine sounds so strange and turns over very easily...

I am going to pull the Cam-cover this afternoon.

Are there any good pictured How-to's about the cam-belt change online? I got the factory handbook but maybe there is something more pictorial out there...

Reverant 03-23-2012 03:33 AM

You might as well tak a peek through the oil cap.

Update - so it's not the Cam belt - I had both the oilcap and the cam-sensor removed and both cams are turning, when I turn the crank...

I swapped in my DIYPNP and it's also not doing anything else...

Might have to swap another cam sensor in...

Here is a (very) short composite log:

https://www.miataturbo.net/attachmen...1&d=1332499357

Maybe someone could have a look...

Reverant 03-23-2012 08:06 AM

Not enough data in there, you need to crank more. However, the crank sensor signal does appear a bit odd.

Zaphod 03-23-2012 09:02 AM

I pulled the cam cover to have a look at the CAM belt - looks fine - though it seems to have some slack.

Could you have a look if the timing marks and teeth between do look correct?

@Reverant - to get a longer logfile I will have to re-attach the cam cover.
Will do as soon as the timing verified...

I pulled a COP before I pulled the cam cover - there is no spark.
The MS3 is working - verified on the bench/stim.

@Reverant - nd the others off course too - here is a little longer composite log...

https://www.miataturbo.net/attachmen...1&d=1332513957

Please have a look

Here is a pic of my composite log:
https://www.miataturbo.net/attachmen...1&d=1332514800

And here a pic how the NB signals are ought to look:
http://img38.imagefra.me/img/img38/7...wm_5981b1a.gif

Looks like my Cam and Crank signal are out of sync??? The two following Cam signals should be inbetween two crank signals - looks like its a bit early just before the Crank signal - I am no expert on that, so please excuse my bad description...

BTW - what does the red line mean?

Reverant 03-23-2012 10:58 AM

If both cam gears look properly aligned, then it looks like the crank pulley has jumped instead. All 4 teeth on the crank pulley should be fully contained between the 1 and 2 teeth on the cam gear. On your log, one of the crank teeth is between the two teeth of the cam gear.

Zaphod 03-23-2012 11:33 AM

I just edited my post when you replied...

This means a complete belt job I suppose...?!

Reverant 03-23-2012 11:40 AM

I guess so.

Zaphod 03-23-2012 11:58 AM

Could someone explain the red line in the composite log please.

FatKao 03-23-2012 02:59 PM

Errors. It usually pops up on the tooth AFTER the actual problem.

Zaphod 03-24-2012 09:13 AM

New pictures - exhaust cam slipped one tooth ?!

Here are some pics after I removed all the stuff:

https://www.miataturbo.net/attachmen...ine=1332594802

Looks like my exhaust cam splipped one tooth - correct?

Here are some pics after I removed all the stuff:

https://www.miataturbo.net/attachmen...ine=1332594802

But what bothers me is - why is my crank pin not at 12' o clock and why did someone (my previous shop that did put in my built engine) make a mark at that point (which aligns with the cam marks (at least with the intake cam at the moment... :loser:)
See pic:

https://www.miataturbo.net/attachmen...ine=1332595893

Edit:

More weirdness...
When I align my crank with the pin up like this
https://www.miataturbo.net/attachmen...ine=1332595893

I am at TDC for cylinder one... (I checked with a very scientific method...)

http://www.ingenieure-reichel.de/upl...2/mx25_008.jpg

With the Crank aligned like this the cams are standing this way:
http://www.ingenieure-reichel.de/upl...2/mx25_009.jpg

What the f...?

Was my check correct, do I have a brainbug, what is going on...?

Please help me out here...

Zaphod 03-25-2012 05:14 AM

Nobody?

Reverant 03-25-2012 05:24 AM

Looks like the intake cam gear is off 1 tooth, which is what you are seeing on the composite log. I can't even tell what is wrong with the exhaust cam.

FatKao 03-25-2012 10:43 AM

Your timing is totally hosed. Whoever put the belt on set the cams when the crank was at BDC not TDC it seems.

olderguy 03-25-2012 10:47 AM

Pull the belt off, check to see that the pins are in the proper place in the cam gears, and redo the whole thing.

Zaphod 03-25-2012 10:58 AM

How would the engine run in that configuration?

I am going to do the whole timing again after I have seen that somewhat geeky but quiet helpful videos...


Zaphod 03-26-2012 07:23 AM

I turned my crank today some more times to see if I can find a spot where the marks all agree... but they where really totally off. As to bee seen in the first picture above it looks like the 1st cylinder was at ~BDC when the cams were at the marks.

How could an engine run this way for 2 years...? Most of all - my signals must have been so that the DIYPNP and the MS3 were able to ignite and inject?
Would this even be possible?

richyvrlimited 03-26-2012 07:42 AM

It won't have run in that configuration, the belt has just jumped that's all.

Zaphod 03-26-2012 07:46 AM

Sooo much... :eek: o.k. then - lets get on.
Assembly as soon as I got my water neck blocking plate and timing belt / tensioners.

Zaphod 03-28-2012 06:49 AM

Parts are rolling in..

Got the belts and tensioners today...

https://www.miataturbo.net/attachmen...ine=1332931780

The freeze plug is installed:

https://www.miataturbo.net/attachmen...ine=1332931780

olderguy 03-28-2012 07:35 AM

A lot of members, me included, put a plate over the freeze-out plug as insurance that it stays in position. A small weeping leak can be detected and overcome, a sudden empty system is another thing.

Zaphod 03-28-2012 07:48 AM

I should be getting that plate this afternoon - thank god I got a friend that can machine these things for me...

So I finally found the main problem that caused all that fuss... me...:vash:

Maybe I shoudl be renamed into Faezaphod or something like that...

When I tried to remove my front waterneck this winter I removed the upper cambelt cover in a very Fae-like way... (though I didn't use a sawzall, but a huge screwdriver..) I removed the cover, did see that there is much more to the waterneck removal - and reattached the cover. But a piece of the cover broke and got ripped of by the cambelt and mangled between cambelt and the crank cambelt pulley... - I suppose that was the point where my cambelt jumped over quite a large bit...

So on to the fix:
That is my third hand I used when setting the cams and attaching the cambelt..
https://www.miataturbo.net/attachmen...ine=1333003686

Thats how it looks now - have to reassemble the rest today.

Just wanted to let you know that the car is up and running again.

At first I overtightend the belt - but the second attempt was good.

P.S.: I had the timing light to reference the timing and I have seen that there is no difference between the DIYPNP and the MS3 in timing for the 99-00.
