I noticed a great oil leak under the car today, from left side, seems just over the suspension arm.
Leaks a lot with engine on and less when off, so I suspect something under pressure.
What can it be?

 

Could be other sources, but if this began abruptly, the first thing I'd check is that your oil filter is seated properly and is tight. Maybe just change it to be sure it's not a bad gasket. One other thing that comes to mind is the oil pressure sending unit/sensor, near the filter pedestal.

 

They are both ok, already checked
the car ha always leaked a little drop of oil
but now it's an oil stream!
could it be the large gasket of the pan?

 

Potrebbe essere la pentola dell' oglio.Ti suggerisco di mettere del colorante nell' oglio. Ho speso 2 mesi, cercando di trovare la perdita dell' oglio, ho cambiato la pentola dell'oglio, la guarnizione della pentola dell' oglio, ho provato a cambiare la guarnizione l'ingettore dell' oglio(O ring)e avevo ancora la perdita. Ho pulito il motore dappertutto, ho guidato la macchina, sembrava che venisse da tutte le parti, ho repulito il motore,a questo punto mia moglie pensave che gli facessi le corna, perche' spendevo tutto il mio tempo lavorando sulla macchina. Dopo che ho messo il colorante nell'oglio, mi ci sono voluti 2 minuti per capire da dove venisse. Percui ti suggerisco di provare il colorante.

P.S. la mia perdita di oglio, veniva dalla copertura della catena dell' oglio.

 

well thats interesting, wish i could read it

 

From Babelfish...

It could be the pot of the oglio.Ti I suggest to put of coloring in the oglio. I have spold 2 months, having tried to find the loss of the oglio, I have changed the pot of the oglio, the packing of the pot of the oglio, I have tried to change to the packing the ingettore of the oglio(O ring)e I still had the loss. I have cleaned up the motor everywhere, I have guided the machine, seemed that it came from all the parts, I have repulito the motor, to this point my moglie pensave that you made the corna it, perche' I spold all the my time working on the machine. After that I have put coloring in the oglio, me there are intentional 2 minuteren in order to understand from where it came. Percui I suggest you to try coloring. P.S. my loss of oglio, came from the cover of the chain of the oglio.

 

so tony is saying put die in the oil, and look for the leak. He did, after replacing the entire engine (?), and found his leak from the front cover (?).

 

front cover, rear seal, omp, oml, or ya oil pan.

 

good job so so. the key word here is . use the oil die frist. dont guess save your self some time and money .
good luck

 

olio and not oglio!

 

Anyway, I will get the car to Mazda, they said it is the oil pan gasket.
tonytt please keep posting in english

 

just make sure before they put the oil pan gasket on. tell them to clean the engie and put the die in the oil it may look like its coming from the pan but there about 8 different place it could come from.

 

sounds like motormounts

 

like i said 900 and 1 places it could come from put the die in and you will be sure
