200sx-Starlet-Jay Posted June 25, 2009 Posted June 25, 2009 hi alljust before i took my NA engine out to replace with the fte, it made a weird rattle in lowish revs, around 2-3k. say u was in gear 3/4 doing 30 mph, then put ure foot down to the floor, it rattled until revs pic up. but if u drive car hard through all gears it doesnt do it?!! its defo not a knocking sound.. recently the other starlet ive got me hands on, its doing same. has 65k on clock, full service history, runs fine no problems, but has started to do this rattle. any ideas???in comparison, when the vvti went on my s14, it made a very similar rattle. it was just the spring that needed replacing.. would it be somting similar on this? like tappet rattle or somting?

Sparky Posted June 25, 2009 Posted June 25, 2009 Yup sounds like a bit of pinking to me, do as Dub says Quote
Steve GT Posted June 25, 2009 Posted June 25, 2009 id say it sounds like what dub and sparky are saying would be he first thing to checkbut BAZ2CRAZY has a good point. in low revs the engine tends to vibrate more so does exhaust etc so just check that theres nothing touching the engine that could be rattling on it or as is stated heat guards etc Quote
200sx-Starlet-Jay Posted June 25, 2009 Author Posted June 25, 2009 could be pre-ignition, try retarding the dizzy. how do you do that lol?its had a new set of plugs recently... some platinum ones. would they have caused it? same ones that where in mine as well. Quote
Sparky Posted June 25, 2009 Posted June 25, 2009 2 bolts on the dizzy cap, undo them and to retard the igntion you twist the dizzy cap towards you I believe, only need to do it a tiny bit but just try it and see, if it gets better, retard a bit more or vice versa Quote
200sx-Starlet-Jay Posted June 25, 2009 Author Posted June 25, 2009 lol just took it out quickly before i was going to attempt it, so i knew exactly in rev range to look for it... and i cant get it to do it now lol. engine was cold tho so may have somthing to do with it! Quote
Mikey Jay Posted July 1, 2009 Posted July 1, 2009 If you're on about a ticking sort of rattly noise I had it on my n/a starlet, my old Paseo and current PaseoThink someone once told me it might be the injectors....?(don't quote me on that though) Quote
