Hey guys i looked at a Starlet earlier and the owner was advised that this was "Piston slapping", however even when cold there is no sound, it can only be heard when the car is revved as in this video at idle, when putting slight pressure the gas to maintain revs and when decelerating.

Wierd thing is when accelerating it can't be heard =/ Hope this is clear as i'm rubbish at explaining stuff :p

Any idea what it is? Thanks!

*Edit* - Going through the list http://www.foxvalleymarc.com/Tech_section/troubleshooting_engine_noises.html i must say that it sounds very much like Wrist Pin Slap watching this vid http://www.youtube.com/watch?v=mVgqHai2qJE&feature=related

I'd say he's chancing his arm walk away thats not piston slap, on forged engines you will get piston slap when there cold but it goes away as soon as there warm that big end is gone imo correct me if I'm wrong people......

Bugger..it was changed on september of last year so yeah, raced lol..

Thing is the motor is only £700 and has a clean shell, reckon it's worth either fixing the motor or throwing a new one in? It's an M reg with 88k miles =]

Thanks
