Tappet rattle on cold start


Recommended Posts

I have just bought a VR6 that me and a mate are going to use as a track car. when the car starts in the morning from cold it gets a slight top end tappet rattle for about 2 seconds then stops and is fine ther after.

The last owner may just have stuck any old oil in so i would like to do that 1st.

what oil is recommended to use?

also are the tappets hydrolic and do you think it could be something more serious?

Definately do an oil change first. Ideally use Synta 10w40 semi synthetic oil from VW or GSF I think. You should get a discount as a premium member at GSF although I'm not sure if there is one on the IOW. An equivalent good quality oil of the same grade would be ok.

VR's have hydraulic tappets so no adjustment there but they are known to be a little rattly on idle especially on higher mileage engines. As long as the initial rattle goes after a couple of seconds then I wouldn't worry. Replace your oil and filter and see how it goes.
