When I start up the car cold, it seems like the engine is fine...but like after driving it around for a while...a engine noise somehwat rattling bothers me...then after you go idle for about 10 mins...the noise goes away again...any ideas? | | | 07-23-2005, 12:05 AM | #2 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Make the radio louder. It sounds like the VANOS. The noise goes away once the oil starts circulating. It is pretty normal. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 07-23-2005, 09:23 PM | #3 | Senior Member Join Date: Dec 2004 Location: Colyumbia S.C.

does it do it continuously once it starts such that you'd be able to track it down? if it's the cat heat shield, you can search on the forums for something like "cat heat shield" and you should pull up some good threads. __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 09-18-2005, 07:44 AM | #7 | Junior Member Join Date: Apr 2005 Posts: 9 | my car was just diagnosed but i'm still skeptical about it...they said it's the timing chain...i didn't have it checked at the dealer...do you guys really think they diagnosed it right? how much do you think the repairs will cost (parts and labor)? is it still safe to drive it under the circumstances? | | | 09-18-2005, 04:01 PM | #8 | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 | is the person you took it to a bmw specialist? i'd get a second opinion i think. how many miles on your car? if you truly need to replace your timing chain (can't imagine - i have 212k on mine and it's fine), it may be expensive. did they give you an estimate? perhaps if it's timing chain related, they just need to replace the timing chain tensioner? __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 09-18-2005, 04:44 PM | #9 | Junior Member Join Date: Apr 2005 Posts: 9 | Quote: Originally Posted by cali-ti is the person you took it to a bmw specialist?
