If you own a first or second generation MINI there are several common oil leaks to both models.
R50 & R53
On the R50 & R53 models the most common ones are the crankshaft position sensor o-ring and valve cover gasket. The valve cover gasket is a fairly easy repair as the valve cover sits on top of the engine which allows for easy removal and re-installation of valve cover. The crank sensor o-ring is on the side of the engine closest to the radiator (front of the vehicle). This o-ring is much harder to get to than the valve cover gasket and can be a much messier leak. It is necessary to remove the front bumper and support to be able to tilt the radiator forward and gain access to the o-ring. Once the o-ring is replaced we always recommend a good pressure wash of the engine for a couple of reasons. The first reason is to be able to tell if there are any additional oil leaks, and the second reason is to prevent any damage to other engine components. The lower engine mount is partly made of rubber, and if this rubber gets oil saturated it will need to be replaced.
On the 2nd generation MINI (R55,R56,& R57) there are also several common oil leaks. The valve cover gasket on these tend to leak, just like first gen MINI. If you have an S model the turbo oil feed pipe is a very common leak and can be dangerous if not repaired. The turbo charger is bolted to/part of the exhaust manifold, and here is where the danger part comes in, when the turbo pipe leaks it sprays oil on to the exhaust manifold. The exhaust can reach temperatures upwards of 1,000 degrees, and here is where the danger lies. There is potential for fire hazard if the oil that sprays on to the turbo/manifold is ignited. This is a very real hazard and cause cause serious damage to your vehicle. We recommend that if you have the turbo feed pipe leak, that you address it as soon as possible. Another common leak on 2nd gen MINI is brake booster vacuum pump which is located on left side top of engine (driver side of cylinder head). Both Cooper and Cooper S models are equipped with these. If you are lucky enough to have the S version the dealer will cover the vacuum pump under the California Emission Warranty which is 7 years or 70,000 miles, whichever comes first. If you have a base model it is only covered 4 years or 50,000 miles. Either way the dealer will charge you around $1000 to replace this part, at The Haus we can perform the same repair using original equipment manufacturer part for around 1/2 the price, and we give you the same 2 year/24,000 mile warranty on parts & labor as the local dealers.
