Hi, I have just joined and would like to ask a question to anyone that may be able to help me. My car has started making a clunky grinding sort of noise when pushing the push start ignition, the noise only happens for a few seconds and then it's fine no other issued just an intermittent noise at start up. Have taken it to the mechanic who said he cant really tell me much as it didn't make the noise for them however had the battery tested and that failed so replaced that yesterday and when first starting it after new battery it started but turned off after about 20 secs but restarted again straight away but its still making the noise. If I can give u any more information please let me know I just have no idea what it could be and its driving me crazy ad I don't want to break down somewhere with my kids in the car! Thanks in advance for any replies really appreciate, I have a video of the noise and will try and attach it. TRIM_20180523_171753.mp4
Hi, Im new here. I recently bought a silver 2003 Corolla Sportivo with 144Kkms. It is a fun car, but it has a weird grinding noise when riding the clutch, particularly in reverse. The noise is worst when reversing from cold start. It is a kind of TZZZZZ noise that is quite loud once I start to reverse, riding the clutch, though stops once I let the clutch out completely. It is nowhere near as loud when engaging 1st, and can only just be heard if I ride the clutch during 1st to 2nd and 2nd to 3rd gear changes. The gearbox itself seems otherwise OK during normal driving, with possibly only the slightest of bearing noises and no syncro issues when driving - it is only bad when releasing the clutch in reverse. The shift action has a pretty average feel to it, but it goes into gears just fine, with only a slight snick. As a side, I find the clutch hard to get just right on take off. I either spin the clutch or bog down. The take up point was originally quite low to the floor, which I have raised a little by adjusting the clutch push rod out 2 turns. I was told that the clutch had always been like that since the previous owner bought the car 3 years ago. It had apparently had a new clutch before she bought it. I have also changed the gearbox oil to Redline MT80(?) and added Nulon additive. I can't recall if the current noise was there before I adjusted the clutch and changed the oil. Some of my thoughts are the noise could be: a thrust bearing problem, but would expect it to occurr in all gears; an input shaft bearing, though I would expect that it would be constant noise whilst driving - unless it is just commencing and is worst under load. reverse gear isn't initially fully engaging, which would be a linkage problem; or an engine or gearbox mount is shot, so the drivetrain is moving under load and hitting something? I note that sometimes when starting the car I do hear a similar noise for a fraction of a second. Any ideas? If I can't get any solid leads from here, I might try fiddling with the clutch rod and bleed the clutch cylinder and adjusting the clutch rod to see if it makes any difference. Thanks, James
