Engine noise on tickover

Post by Tony2 » Mon Nov 21, 2016 4:22 pm

Hi
Finally been able to log on, fab.
Bought a metallic grey 1990 Citroen BX 1580cc Millesime from my neighbour in France,he has just given up driving at 90. Really really clean car inside and out, however on tickover there is a knocking noise from the engine, not regular enough to make me believe piston or ends and goes as soon as engine speed is increased, any thoughts anyone?

Welcome to the forum. :D

Two thoughts:

1) Worn/damaged engine mount?

2) Noisy/worn hydraulic pump?

Do you have a stethoscope or long screwdriver which you can put to your ear? This may help pinpoint where the knocking is coming from. Could be anything.

If the noise goes as soon as the revs are raised then it sounds like the HP pump is under load at tickover.

Thanks guys, am back in England now and Citroen is in garage in France, am going to try and swop cars (2CV to France) over sometime soon hopefully then get down to sorting BX out. Anybody know what a Millesime is spec wise, was it a ltd edition if so, based on what?
Have had the 2CV rigged for towing with an A frame and brake arrangement, to go behind the motorhome, 1st trip last half term, 700 odd miles, was a dream, forget its there and look down at speedo, 80mph back to 60 to keep the French police happy, little change in petrol consumption, i love that little car.

My understanding is the 'Millesime' is the French equivalent of the UK 'Athena' version of the BX.

Thanks re spec of car, so what does an Athena have or have not, where does it fit in, looks quite sporty with spoiler and seats are quite smart too.
