Oil leak and no charging
 

Hello everyone!

Let me describe my issue:
2010 Mazda Tribute 2,5l has lost oil. I noticed that by oil spots on the pavement. The serpentine belt side covered with oil. When I noticed this I decided to drive home (about 10 KM) and on half way ABS light blinked few times and power steering lost the power. Also there was not any more turn lights, Odometer indications, radio. I was able however to get to my parking lot but could not restart the engine after I parked and stopped it. So far I removed alternator and confirmed that its clean inside and all diodes are OK.
Any other idea about what to check/repair.

Thanks in advance

I’d guess the belt was slipping on both alt and power steering pump to give those symptoms. Fix the oil leak, clean the pulleys and replace the belt, then see if you still have a charging issue.

Simonsi, thanks for reply!
I actually reinstalled alternator and tried to start the engine. Everything is okay on this side (you are probably right about slipping).
The problem is to detect the leak. Is this crankshaft seal or front cover seal? All this side is covered with oil so it's really hard to tell where exactly it leaks.
Tomorrow I will add some oil into the engine and will try run it. Maybe this way I can find the source?..
Anyway I'll update.
Have a great weekend to everyone!

I would clean the engine, then run and try to see which gasket or join has failed taking into account the oil will only wet the engine below the level of the leak. If most of the end of the engine is oily then I’d suspect one or both rocker cover gaskets.

Okay.
Thank you for advice!

Hello all.
Finally I found the source of oil leak.

The stud of idler pulley that is on Timing Cover broken!..
I'm very disappointed:(((
Looking for replacement timing cover.

Ouch! Thats a real shame, hope you find a cover ok, biggish job to change it.

The job is half-done;) Only Harmonic balancer left to remove(screw is too rusted)
I paid a "Timing Cover" from a local Mazda dealer for 250CAD+tx. Picking it up tomorrow afternoon. Will play with it mostly on Saturday.
Just by curiosity the cost of replacement at dealer site is 1200CAD!!! :O CRAZY!!!
Thanks again for support!

Hi all.
Today I replaced Timing cover.
The biggest challenge was to remove Harmonic balancer bolt. After few tries with impact wrenches I made an additional tool and finally the bolt was "broken"!

Tomorrow morning I will fill the oil and will test it. ;)

Have a great Sunday to everyone!!!

Another update:
This morning the engine did not start:(
It cranks but there is no even intention to burn the gas. The battery was dead so I used jump starter. After few attempts something blown under manifolds and blue smoke has come out.
Yesterday I removed manifold and injectors line because I wanted to replace the hose that "causes" rough idle. The hose that I have bought from rockauto was wrong so I left everything as is on that side.
Could I accidentally move out the timing? or something else?
Any suggestions will be appreciated!!!
Tomorrow morning I'm going to search for a repair shop near by...:(

Thank you

Oh no - do you mean electrical smoke from under the inlet manifold or oil smoke from under an exhaust manifold?

as you have had the inlet manifold off I would remove it again and see if any wiring got caught/damaged??

It looked and smelled mostly like oil smoke, but could have been something else... There was no any wiring passing behind manifolds, I checked it carefully before to get it back.
I have all wiring/connectors rechecked this evening, looks OK.
I will try to read ECU errors tomorrow and see what it says.
Just reminded, I turned the crank with a ratchet today and at some point I felt an enormous resistance, like something blocks hard the crank. so I turned it a little bit back (means counter clock wise and really a bit) and then it moved until it gets blocked next time. And it felt like there is no compression in cylinders...

You should feel resistance every 120deg as you turn it, compression will feel quite springy, if you feel hard resistance then it maybe something else. Did you take any pictures as you changed the timing cover?

[QUOTE=simonsi;174789]You should feel resistance every 120deg as you turn it, compression will feel quite springy,

I know, but now it's not really springy now.

I did not take any pictures as nothing has changed except new cover.
