Having problems with your 1998 Volvo S70 ?
Car is knocking
\015 I had to replace the heads on my engine in April every since that time my car knocks within the 1st 20mins of starting the car up, the knocking seems to be coming from under the car. When it is warm out side it doesn't knock. lately it has been knocking everyday since it is colder out side.\015
Sounds like a bad connecting rod bearing or a carbon knock, de-carbon the engine and retest for noise, if it is still there the engine will need to be torn down the crank refinished and new bearings installed.
