Unread post by des1770 » June 7th, 2014, 8:11 am

2013 BT50 Auto
Just had 20,000km service and told the engine rear crankshaft main seal is leaking.
transmission will need to be removed to replace the seal. not happy. Ute is 6 months old.

Anyone else had this fault.

I've read about a few, or I have read about 1 a few times. You know how it is with the interwebs :crazy:

Mine hasn't got a leak, but it is also only 2500km on the clock.

That is unusual!
Mazda's are always pretty good. Perhaps they are using the same supplier of seals that Oldhen uses in the Colorado.

The GM dealers have stocks of them waiting for the vehicles to leak. They knew when the vehicle started to be sold. That is how sure the company is of their GM product. maybe Cut Price Seals won't get a new contract.

I would be surprised if more than a handful of Mazda's have seal leak problems. If it was assembled by Fraud then different story. Perhaps Fraud are the ones getting the seals for all the 5 cyl diesel engines. Now that would be worrying.

Hoyks.
At 2500km you would hope not. At 250,000 maybe.

I think 2500km is pretty good MyDmax ,one poor bloke last night on the new ranger forum had his turbo implode after 300km,hardly made it home from the dealer!! The ranger looks good and on paper it ain't bad but the QA is terrible

I suspect my 2012 BT 50has a rear main seal leak and have mentioned it to the dealer. Gets a little damp on the transmission then I wipe it away and sometimes it gets wet again and sometimes stays dry for a good few thousand km. Waiting to see if it gets worse. First noticed it at 15,000 km, checked at service but had not reappeared. Then after 20,000km service damp again. I have driven 5,000 km in the last two weeks and has remained dry since last wipe. I thought it might be oil from the filter change but there is no evidence of spilt oil anywhere. In my case it could be clutch master cylinder fluid or transmission oil from the input shaft as I have a manual.

I have just come back from a long weekend in the high country with some strange stuff happening with the car so will start another thread about that.

Mine was replaced by Mazda just after 45,000kms.
Now at just over 55,000 its leaking again, so its going back this Friday.

I also have a leaking rear main 2014 3.2 ranger although more like a weep. My mechanic spotted it at my 15000 service. If or when I replace it I will use a good quality after market seal and get my mechanic to do the job I would not trust the dealerships on the Central Coast with my billycart. I know they will check for any possible cause of the premature failure of the seal and not take it for granted it is just a faulty seal

Picked up the ute this morning.
Dealer did his utmost to fix the leaking rear main in a hurry, including dropping drive shafts, auto transmission and all associated fluid and electrical lines..
Took them 7 hours and drove home 120KM and not leaking again...fingers crossed.

If anyone can get hold of a used seal and take a picture of it so we can see the brand and the size and features, that would be good to see.

Same with the transfer seals too.
It will be handy to know the source of the seals, ie reputable brand or unknown seals made to order by a province in some well known country. Unknown seals may not seal. Arf Arf.

Looks like i'm not alone, i have a 2012 manual 47000km started leaking a few thousand ago, spoke to Mazda they've had a few in for the same problem from the same series P. I was told that the second series Q where all sorted, by the looks of it nothing has changed as 2014 models have the same problem. Had i known earlier i would've kept my Magna at least i knew what i was in for.

My old man was told by a holden dealership that the rear main on his Gen3 V8 was leaking a few years back. I had a look and it was the rocker gaskets and it was running down the back...dickheads at the dealership didn't do much in terms of checking where the leak actually was....

Maybe check that its actually the rear main and not something simple like a cam or rocker cover...or just an oil spill...

......and its back at Mazda again. For over a week now, just phoned and it looks like I wont have it back till next week.
Rear main seal, third time in just under 80,000 kms.
The seal runs on the outer surface of the crankshaft flange, and according to a mech mate the culprit may be overtightening of the flex plate bolts, causing the flange to 'cup' slightly, hence the seal does not make full contact.
Apparently Ford issued a service bulletin earlier on about lower torque settings for said bolts. Mazda have no such notice according to the dealer service manager........

Degreased it and checked again after driving for a day or two and unfortunately it looks like the rear main seal, bottom of housing has oil coming through the join. I was hoping it was something easier to get to. I can't believe that what looks like a $5 part can be so painful and time consuming (big $$$ to fix out of warranty unless you do it yourself). What worries me is all the things that can be stuffed up whilst replacing the seal.

3 times in 80,000 kms to me is a big stuff up by Mazda, i feel sorry for you as much as i feel sorry for myself.

I'll print this page off and take it to Mazda and confirm they know what a torque wrench is!!! and no apprentices please (they have to learn, but hopefully not on my car...)

Dragging up an old thread *sorry*.

Mines done the same, certainly the front,
Mazda did the GB under warranty (after a month of arguing).
50 thou and the clutch had no fluid and started slipping too...
refilled the brake/clutch reservoir and its been fine since but getting more leaking from the front (engine) end of the gearbox.
Is it possible the two issues are linked?
I work for my weekends... and damn it, I WILL enjoy them

Well looks like Mazda haven't fixed this problem yet. I have 2016 GT auto. with just 22,000 kms. Whilst underneath today doing transmission cooler install noticed oil around motor / bell housing joint, took it into dealer and yes leaking rear seal. Booked in on 22nd of this month for transmission removal to repair seal.
