I have just had my 2014 XTR Dual cab 70,000km service carried out and was informed that the rear main seal needs to be replaced due to an oil leak. I was also told that if the replacement seal doesn't stop the leak the engine will need to be replaced. As fortune would have it I have two months of warranty left. Has anybody had the same problem? I have read on a few blogs that some BT50 owners have had seals replaced but not whole engines.

I have a 2016 BT50 3.2ltr, at the 20k service I reported the engine to be leaking oil onto the floor of my garage. Mazda reported post service the Rear Main Seal needs replacing. The seal has just been replaced and I will be keeping a close eye on it. Anyone else here that has had this issue?

BILs 2014 Ford Ranger had to have leaking rear seal replaced under warranty as well .... same beast. Sounds like a common problem that hopefully manifests whilst under warranty. Guess it is a cheaper option for Ford and Mazda to just repair the few that leak whilst still in the warranty period rather than do a recall. After that owners expense :woot:

The only reason they are saying if the new seal wont stop the leak is because the shaft may have some wear on it due to the seal but to replace the whole motor is a load of crap they just have know idea at all. A speedy seal would fix that up in know time and they should know this and on mine when they changed it they found not enough sealant around the housing was put on if you can believe them.

Hi Guys,

Thanks for your comments. It does sound silly to replace an engine because of a leaking seal but the service manager also stated that they had done several engine changes because of it. Maybe there is something Mazda are not telling us about these motors. There may be more to it than a leaking seal.

More then likely its because of the warranty, putting a speedy sleeve on a motor is a good fix and very cost affective but one could argue that because its under warranty this type of fix is unacceptable so this is why maybe they replace the motor. But for a vehicles crank shaft to have worn groves in the shaft at even 100k's is unlikely not enough to worry a new seal anyway.

My BT go's in for a new oil seal tomorrow. See how long it lasts. Its starting to sound like a problem for these 3.2 lt motors.

Picked up the BT from Mazda this afternoon after oil seal was replaced, talking to service guy Mazda have known about this problem for some time and only fixing when noticed. The bit about motor replacement is if the seal is to badly  leaking and the patch will not cure. He stated that it was more cost effective to replace the motor than to strip down the engine insitu. Mazda must be making to much money!

Hi Guys, I am after some advice. I have a 2014 BT50 and back in March this year (driven 16,000 kilometres) I had an oil leak fixed by the local Mazda dealer. The report from Mazda said the leak was due to, "insufficient seal causing oil to bypass". Apparently, they replaced the crankshaft oil seal and the job was done under warranty. I found the leak after seeing a few drops of oil on the garage floor.

 

A couple of weeks ago, after a trip over a lot of gravel roads, I had a local mechanic give the car a quick check and he found that the rear main oil seal had started to leak (26,000 kilometres on the clock).

 

I took it back to the same Mazda deal and they told me they could see the oil, but could not find a leak. They cleaned the oil up and asked me to keep an eye on it. When I asked how it could be there if there is no leak, they tried to tell me it could have been a result of oil being spilt at the last service. I was not impressed but as I do not know a lot about motors, I agreed. When I got the car home, I checked and I could see there was fresh oil again. 

 

I would like to hear from any other BT owners who have had problems with getting Mazda to fix an oil leak under warranty. I am sure they are hoping they can put me off until the car is out of warranty, next March.

Paul,

Take it back to the Mazda dealer and ask that it be repaired under warranty. If they give you a hard time just mention a report to the ACCC will be lodged also to the Ministry of fair trading "aka" lemon laws. If the car is under warranty they have to repair or replace. If they still refuse to deal with it try another Mazda dealer and see there response. Good Luck.

take it straight back paul and tell them that you had an independent mechanical assessor look at the car and it is shown to be the seal..........possibly an RAA (or interstate equivelent) report MAY add more weight.

 

had mine looked at today, back order on the seal with a two week waiting list so It will have to be done along with the service after I come back from our next foray into our magical land (heading out all of November returning December)
