Engine ignition timing has been messed up. Have a qualified mechanic check & reset it.

cyborg123:
I believe the valve stem seal was replaced due to the plug being soaked. OP, come and clarify.

That said, is there an OBD port on a car of that year? I'm not sure the OP can enjoy the benefit of a scan.

TRYGO:
Terribly sorry for your situation.
What the mechanic replaced is called VALVE COVER SEAL. And I don't see how that could result in the tining being tempered with, as Kong as the belt/chain wasn't part of the repair process.

All the parts replaced, shouldn't have being replaced in the first place. Keep those parts, and have the car SCANNED of codes first! Without doing that, you'd keep throwing money at parts.

Isn't there a check engine light on the dashboard displaying?

I hope the "rewires" you called haven't spliced the car's wiring harnesses, and did terrible connections?

Yes they say its oil seal, but he changed a seal in the plug wire "distribution box". I don't know if he replaced the right seal.
Can the oil seal be located at the "distribution box"? Or has he replaced the valve seal instead of oil seal?

Please don't mind my lame terms.

Its a 2012 Mazda 626.

cyborg123:


From the picture you uploaded, your car can't be a 2012 model. I'm thinking 1994 - 1996.

There is a seal on the distributor cap assembly but I don't think that can cause the spark plugs to get wet. From your initial complaint, I think your mechanic has replaced your valve stem seals but he has somehow messed with the ignition timing assuming all vacuum lines and wires have been thoroughly checked.

What exactly did the mechanic do to the "unusual noise" he detected?

solosolo111:


From the VIN check it actually shows 2012 version to my amazement. Its only one of the plugs that is always soaked and the mechanic says its oil seal that is leaking and I left the car with him for the office. By the time I came back he showed me a little thick round rubber that he had changed from the distributor cap assembly. He said he traced the "unusual noise" to the timing belt and got it resolved, he never told me what he did. Am going to get another mechanic to do a thorough check of the oil seal and timing belt.

Thanks alot for digging deep.

TRYGO:
Absolutely! The timing belt can be reset, if your mechanic knows what he's doing. He might know what he's doing, considering that he did replaced the oil seals by the ignition timing area.

If your car uses a distribution box(has spark plug wires), then, probably the ignition has being retarded too much, causing it to not start.


PS: If it displays the key sign, without starting, then I suspect there must be something going on wrong with the ignition module ID. It may not be identifying the signal being sent from the ignition, to the ignition module.

It could also be that your car's security system is preventing the car from starting, if it has developed some kind of fault.

Where is your location?

solosolo111:
Got an experienced widely recommended mechanic to handle the job. Got the timing belt reset and the distribution cap which he discovered to be faulty replaced. Finally he has also discovered the brain box is affected (burnt). He is going to get a new brain box for it. Though the one the car came with is a sensor brain box, because of cost he wants to try an open brain box.

Any major difference between sensor brain box and open brain box?

This the update so far, I will keep you posted after the brain box is replaced.

Thanks for your useful contributions and care.

@cyborg123, @TRYGO

I have never heard of those ECU (brain box) terminologies before.

Y don't you just get the original Brainbox, and program it to the car? Saves you a lot!

Car came to the shop without a fried ECU. So, how cone now, a brain box was fried, and has to be replaced? Sounds .....

After replacing the faulting ECU(brain box) and the Distribution cap, the car has finally picked up and is doing fine.

Cause of the damaged ECU(brain box) was discovered to be bridged wires. This was messed up by the initial hands that handled the car on my absence, because I drove the car down myself to the mechanic, the only problem was the oil seal leakage. I came back to pickup the car only to discover it could no longer steam when started.

Thanks guys for all your numerous contributions and very useful suggestions.

@TRYGO, @cyborg123 and all others am indeed grateful.

Lesson learnt: Take your car to a trusted hand. I have never used that mechanic before, taught it was a minor problem any mechanic could fix only to end up in a serious mess.
