Bonto 14 Report post Posted March 20, 2014 People of the world! I've noticed a bit of a knock on cold start in the morning. It is not audible inside the car once underway and once the engine is warmed up all is quiet. It's hard to pin down where it's coming from in the engine bay... but it is a knock, rather than a tap/valve gear noise, if I'm any judge. Sounds like 1/revolution. The car is an E28 525e, with the ETA 2.7. It's done 208,000kms though the previous owner/s wasn't all that big on maintenance. Starts and pulls well otherwise and there are no warning lights showing beyond the oil change schedule thingo. Any thoughts? Cheers all, Tom Quote Share this post Link to post Share on other sites
BM WORLD 1283 Report post Posted March 21, 2014 the eta block quite often have a bit of piston slap when cold. but check its not the camshaft or oiling to the camshft etc Quote Share this post Link to post Share on other sites
Bonto 14 Report post Posted March 21, 2014 Cheers Brent. Would have thought camshaft / camshaft oiling would have been more rackety in the way of valve trains.. but good to hear anyway. Oil change tonight before some road tripping over the weekend so will keep an ear on it and if it's all going pear-shaped well then I might be in touch! t Quote Share this post Link to post Share on other sites
