1st Gen R50 Cooper Most liked posts in thread: R50 oil seal?

Your MINI is not leaking oil it is marking its territory. All engines weep, seep & leak a bit.

 

I hate oily engines too. I clean all of our engines twice a year. Keeps them nice & spiffy.

 

This would be the Library article on replacing the crank sensor seal

Crank Sensor Seal Replacement - Library

 

The crank sensor is a quick fix with a bit of black RTV, don't waste time replacing an o-ring that will do the same thing down the road, just take the sensor out lay a bead of RTV around the base, and reinstall.

The crank seal is notorious for leaking, but while cheap, you need to investigate if that is actually the culprit. A leak over there can be anything from: oil pan gasket, timing cover seal, crank seal, filter housing gasket (would have to be REALLY bad), or even a failed filter o-ring if you recently did an oil change. But the latter usually ends in you expelling about 3-4 quarts of oil all over the ground before noticing the leak..


If you do find that you need the seal, we have them on our website: MINI Cooper Crank Seal R50 R52 R53

You will also need the crank pulley install tool, 3 jaw puller, and the MINI tool to install in the center of the crank so you have something for the puller to engage against, you need the special tool or a bolt and cut the head off, you will cause damage to the end of the crank if you don't.

We rent out the all the necessary specialty tools except for the 3 jaw puller which you can get from your local parts store.

Check you PS fluid. The hoses are know to leak. If you are low you must use the correct fluid to top up. Pentosin CHF 11, you can get it at O Reilly's auto parts.

 

Is this the seal you may be thinking of?

^^This process sums up everything you need to fix that damn O -ring. ^^

Most people think they have a leaking oil pan gasket which is not the case. This damn seal leaks oil down the front of the engine and blows back on the oil pan making it look like your oil pan gasket has failed. I had the same issue and only replaced the O-ring and cleaned my oil pan. Now, going on two years, my oil pan is still dry.

I also think the replacement O-ring is a little larger then the original one and that's why it was leaking to begin with and the new one correct the defect.


Kind of sounds like an F56 oil issue? :idea:

 

They used to say if your British car was not leaking oil.....it was out of oil.

I hate oily engines so I'm swapping the seals on a regular basis. I think I've swapped the gearbox seals for axles 6 times already because once in another car I didn't finish a rally because the seal blew.

 

That is a common failure, clean up with alcohol. Yes you can drive it, but you need to replace it. My MINI is on its third mount. It is DIYable.

Send Steven at eMINIparts.com a PM he can set you up & very likely be the best price you'll find.

Some folks like aftermarket mounts, but for me I use the stock one. The NVH from the aftermarket ones would bother me.

 

Spiffy...nice word

 

I just removed the nut,jacked up the engine and put a rubber donut on top of the mount.
