check volvo forum

What you are probably hearing is referred to as "piston slap". It occurs over time as the side-to-side motion of the piston as it moves up and down in the cylinder slowly wears the lower walls of the cylinder, changing it more cone-like. This causes the bottom edge of the piston skirt to strike the bottom edge of the piston wall as it transitions from its lowest point to begin its upward stroke. This was a issue on the Volvo Turbo engines. Google it and you will see that they made changes in 1993 to help prevent this. This problem will not go away. Eventually you will break a piston skirt and that will be the end. If you can, get the engine overhauled before the damage is permanent.

About 700 RPM

Volvo recommends for Volvo S80, changing the timing belt every 105,000 miles. Needless to say, they are pretty religious about this now.
The B20, B21, B23, and B230 engines are non-interference engines, meaning that the camshaft can be rotated independently of the crankshaft and no damage will result to the engine. That is, if the timing belt breaks, the valves will not hit the pistons; the engine will simply stop.
On the other hand, the B234 16-valve engines and any of the other Volvo multi valve engines are interference engines. Loss of the timing belt in these engines will result in severe or fatal engine damage.
Your car might be fitted with:
2.8L (VIN 90, 6th & 7th digit, B6284T eng, turbo)
2.9L (VIN 94, 6th & 7th digit, B6294S eng)

Most car dealers recommend maintenance services at 30K, 60K, 90K and so on. The 30K service is mainly focused in inspection of the systems and replace of the fuel filter.
The 60K is expensive for cars with timing belt. The coolant, transmission oil and filter, and the brake fluid has to be changed. The air filter and spark plugs has to be replaced at this time too.
Most costly is the replacement of the timing belt. Volvo recommends for Volvo 240, changing the timing belt every 50,000 miles. Needless to say, they are pretty religious about this now.

Hi,
From your very brief description I can only guess a response?
First is the Battery o.k? next is there a glove box light or boot/trunk light stayng on? does the Radio turn off when ignition is off?
Check all areas for possible power drain, failing this I presume you have the B23 or B20 engine? your alternator Diode pack may be faulty leaving an open circuit when not in use.
You could try disconnecting the alternator to see if it sorts it.
Finally try using a Multi meter to see how much drain is being taken from battery when engine is not running.
Hope you sort it?
