TonyR Posted May 5, 2003 Share Posted May 5, 2003 Returned from Stoneleigh this afternoon in my 1.6 Superlight, nipped out to fill up with petrol to have a run out to Cadwell later tomorrow, started car after filling up and instantly a nasty tapping noise appeared from top end. Any ideas? I suspect cam follower or broken valve spring. Hope the warranty covers this only done 2300 miles. Fingers crossed I can get it fixed before my first sprint-Curborough.

Paul Ranson Posted May 5, 2003 Share Posted May 5, 2003 Tappet aeration can sound pretty nasty. Is the oil level adequate, and does it still rattle? Paul Link to comment Share on other sites More sharing options...
TonyR Posted May 5, 2003 Author Share Posted May 5, 2003 Thanks for the prompt replies. Plug cover, exhaust and inlet manifold nuts tight, Oil level fine and still very clean. I will leave overnight, and hope this will any allow air to clear from the cam follower. Strange how instant this occured on starting engine after a 25-30mph run for half a mile from home to my local petrol station. TonyR Link to comment Share on other sites More sharing options...
TonyR Posted May 6, 2003 Author Share Posted May 6, 2003 Problem fixed. Started engine today let oil warm up and noise cleared. Must have been tappet aeration, as Paul suggested. Edited by - tonyr on 6 May 2003 18:04:44 Link to comment Share on other sites More sharing options...
Alex Birtwisle Posted May 6, 2003 Share Posted May 6, 2003 a bit late, but I'll add it anyway... ... make sure the engine is hot and running when you check the oil ... Alex S713UMY 1.8K Viper Blue and Black Link to comment Share on other sites More sharing options...
