I have 2007 mini and it is burning a lot of oil and has been for a couple years. the mini service dude told me to put in 2 quarts every thousand miles as well.

tell me, did you find any problems that caused this consumption of oil or did Mini just tell you that the car was the way it was.

thanks Chris

Ditto the oil cooler.

THIS FIXED MY OIL CONSUMPTION ISSUE.

BEFORE FINDING THIS FIX I HAD DONE

OIL FLUSH

STRIP DOWN CYLINDER HEAD AND DECOAT HEAD AND REPLACE VALVE STEM SEALS.

REPLACED PISTON RINGS AND DEGLAZED BORE.

FITTED THE 2 BLANKING CAPS NOW CAR SPOT ON. HOPE THIS HELPS

This technical modification is applicable on the following cars:

• Peugeot 207 GT / Rallye / XS / THP150 1.6 Turbo 150/156hp

Stopping oil from getting into the intake manifold directly from the crankcase

The latest and greatest modification for getting rid of oil in our intake manifold, which is causing so many problems in the cylinder head and intake valves, comes from Peugeot themselves.

The new RCZ and 308GTI with the THP200 engine have a small difference in their intake manifold compared to the older models.
While the manifold body is the same, there is a very small cap that closes the rear PCV hose in the THP200 engine, which does not exist on the THP150 and 175hp engines.

PCV is the Positive Crankcase Ventilation system, which forces blowby gases back (and a lot of oil coming with it) in the intake system.

This cap is very cheap and available from Peugeot (part code 0361S4 ), using it saves the trouble of having to clean your intake from oil and combustion residues.


The difference between the intake manifolds can be seen in the following pictures from Peugeot Servicebox.

Part number 8 is the cap that closes the PCV return hose from the engine to the intake manifold.

Installing the cap in THP150 / 175 engines

First remove the rear PCV return hose. Press the clip to release it from the engine cover.

Intake manifold side

Press the clip on the intake manifold to release the hose again.

Remove the hose from the engine bay.

Install the caps

<*** src="file:///C:/Users/Gary/Desktop/oil%20consumption.php_files/3.jpg" alt="Closing the PCV return inlet, intake manifold" />

Both caps installed, no more oil in the intake manifold.
