206 head gasket

[lexi]

Have a 206 03 plate 1.4 petrol auto here, just acquired, belonging to my daughter. The classic signs of HGF. Oil dripping down onto aux belt from HG line on off side of engine block. Creamy brown on expansion tank cap and black oil inside the tank. First line of attack. Is there an oil cooler to check with it being auto? Got to do the HK anyway but need to look for associated or other possible causes first. Thoughts please. 53k miles on car.

DO you have the VIN Lexi, so I know what is fitted.

So yes, this has the oil cooler as seen in the diagram.

Thanks Marc. Anyone any experience of these coolers failing...........and fixing them? Still probably needs HG doing anyway but will look at this too.

Sorry - I've not had an Auto - since the Semi-auto C-Matic on the CX!

Elis did a modification on his C5 X7 with AM6:

and David had to change his cooler after the dreaded chocolate milk shake episode on his C6:

Those oil coolers have been known to fail. As you say you have an obvious head gasket oil leak, so replace that cooler at the same time, it wont be very expensive.

If there's oil escaping the HG then chances are it needs doing anyway, but the oil/coolant mixing could also be the thermostat housing on the gearbox end of the engine. Our '06 1.4 had oily coolant and it was the plastic housing not being sealed to the head properly, but they do warp/crack too sometimes.

Why they used plastic for this part in the first place I'm not sure, probably lasts "long enough" and is cheaper than alloy...

Thanks for reply’s I am away atm but got a phone call from daughter to say cat would not start. She got rac out and looks like engine has seized. She says she saw no overheating light, parked the car and would not start in morning. RAC man put auto in neutral and tried to turn crank pulley with spanner and no deal. Will see when I get back

So just back and went round for a look at this 206. Got a 22mm socket on Crank pulley and the engine turns freely. Took rocker cover off and valves moving as normal. Don't know what Rac man was turning, but Grandson says he was talking about an 18mm socket on something?? Symptoms are the same in that starter will not operate. Will get back round when weather dries up here and strip off starter after having a bang at it while on the key.
There is what looks like an aftermarket key and possibly an ignition barrel swop. The original Pug key and fob seems redundant and will not fit the ignition barrel being a different cut to the aftermarket one.
Could be immobiliser ? Left Multimeter in caravan after pussying with a fridge at weekend. I suppose MM on the starter and it drawing volts when key starter turned will rule out immobiliser fault? I will try jump leads from battery to starter although Rac man said he tried this ...........I will try again though!

So yes, this has the oil cooler as seen in the diagram.

Marc: Is there any info on how many teeth the cam belt has from that vin? There are 108 tooth and another one. Just gathering bits up ATM

[GiveMeABreak]

There are 104 teeth on the belt for the TU3JP engine on that VIN (PSA Part number: 0816F2). They also have a cheaper brand part: 1633126680.
