    Default Xantia series 1 engine pinging

    I have a series 1 Xantia which pings under load on PULP 98. I took it to a Peugeot specialist in Adelaide to see if he could resolve it: no luck. He couldn't get his diagnostic gear to sync with the Xantia's - end of story.

    Any suggestions as to a possible remedy?

    Hi, the most noticeable pinging I've had in recent years had a main causative agent the same in both cases. Blocked catalytic converter.

    The other possible issue is when a timing belt has been changed and the old damper used as "indexing" for the crank pulley, if it has slipped on its rubber bonding ring then the car will be reassembled with the timing out by some amount which may vary from small to large. Again, it can ping.

    They normally ping when the ignition timing is too advanced. So, the timing needs to be retarded a degree or two. How that is achieved on a car with electronic ignition is anybody's guess. There are no available adjustments. There is no distributor. If the cam timing is out you would have trouble getting it to start, and you could risk valve damage.
    On the Xantia I had it was resistance from the HP pump which altered the timing on the crank pulley. If you remove the timing belt covers you could check the cam timing, but the crank pulley ( harmonic balance) would have to come off to check the position of the woodruff key on the crank to comfirm it's actual position. Once found to be correct, with no 1 piston at TDC, both valves closed ( on compression stroke, not exhaust stroke), the camshaft marks have to line up. With this as a starting point , you could change anything if it's out a tooth either way, but then you must ignore the timing marks on the crank pulley.
    The rubber inner parts of the harmonic balance can deteriorate which then allows the outer rim of the pulley to go off its marked position. So, you time the camshaft to the crankshafts position, not to the markings on the pulley.
    If you can't allow yourself to do that you will need to buy a new crank pulley.

    Hi,
    Does it have a knock sensor ? If so then replace it !

    Do a compression test and see if a carbon load in the head has raised it too much. The Magnetti Marelli injection system does have the capability to retard ignition using a lexia/diagbox but it is a fixed retard that also reduces performance. After experience with a 1.8 306 and several 8 valve BXs, our family thinks the combustion chamber design is not all that well designed hence the move to 4 valve configurations in later models that allow much higher compression for much higher efficiency.

    Get yourself a 16Valve Xantia, they are a fantastic engine.

    Cheers, Ken

    Rebuilt head?

    PULP 98 - which brew - is it only the local fuel you have used - tried others - not all the same?

    Long shot here - have you tried some water injection to clean the carbon deposits out of the combustion chamber?

    Thanks, everyone for your responses.

    My take from them is that the most likely culprit is either a blocked catalytic converter, or the crankshaft pulley / harmonic balancer slippage issue. Any suggestions as to the best way to check the catalytic converter? Also source of a new one?

    Could also be a faulty knock sensor. I'm not sure whether the Series 1 has one. Can anyone answer that one - and if it has one, where it is?

    As I have a couple of other vehicle options and not much spare time at the moment, this is one of those 'when I get a moment' issues - but I'd like to resolve it, as it's a nice Xantia and I much prefer its ZF auto to the AL4 in my Series 2 (twin cam is a much nicer motor though, I agree). ZF auto on the Series 2 would be an improvement.

    It doesn't have a rebuilt head and I've generally used BP 98. Water injection: not sure how you tackle that on an EFI motor.

    Ken W, you've raised an interesting point referring to Lexia. I have a Lexia setup that's supposed to be compatible with the Series 1, but haven't been able to get it to work. Any clues?
