Thread: light knocking when warming up

hi his n hers thanks for the reply i would imagine it could be either piston slap or perhaps 1 of the small ends a bit too much clearance i tried it again today it rattles for a few minutes but when really hot theres no knocking which i think is good cause it gives me an excuse to get it very hot so it dont knock lol

Welcome. Noises of any sort are notoriously difficult to diagnose accurately over the internet. Nothing beats a trained ear under your bonnet. What you describe is most likely light slap, might be the early onset of bearing damage (unlikely), could be something as subtle as a degraded heatshield or a noisy injector. If you tell us whereabouts on the planet you are, someone might be able to suggest a suitably local trained ear.

You need a pro to listen to it to confirm but it is probably the piston slap problem that afflicted the majority of MY97 cars. You want to hear mine at 5am on a cold morning. Sounds worse than a bag of spanners till warmed up LOL
