ballsdeep Posted April 29, 2018 Share Posted April 29, 2018 (edited) Iv done some searches but nothing quite matches my symptoms. Im getting a noise only when upto temperature my first thought was its the spigot bearing but i only had this done last year along with the release bearing, clutch and flywheel. Iv had very little time to investigate but what i have found is the noise almost certainly goes when the clutch pedal is pressed. The only other thing i have checked is the viscous fan which seems to have more resistance when cold than it does when upto temp? Cold it spins maybe 3/4 before stopping, hot it will spin maybe 2+ times. From what iv read it should be the opposite? I can also stop it by hand when upto temp. Any thoughts on this? Could it be something else maybe gearbox? Really im clutching at straws, I’d like to think a spigot bearing should last longer than 12months and less than 2/300 miles.

Dr_Doom Posted April 29, 2018 Share Posted April 29, 2018 (edited) Are you running the W58 5 speed? They’re notorious for this noise, I think it’s the input shaft bearing in the gearbox. Is it a whiring noise on idle that goes when you press the clutch pedal in a bit? 2 of the 3 boxes I had did this even after a fresh clutch, release bearing spigot ring etc...

ballsdeep Posted April 29, 2018 Author Share Posted April 29, 2018 Yes w58 on na-t so I guess it’s understandable if it’s starting to fail now. It’s been a great box so I’l look into repairing it. Is it a rebuild job or can anyone tackle it. I’m not overly impressed with dropping the gearbox again, is there any checks I can do before I commit?

Dr_Doom Posted April 29, 2018 Share Posted April 29, 2018 It’s a bit of a lottery really. It could go forever like that or it could break really soon. The W58’s do seem to last longer with NA-T than NA-TT. I think it’s the low down torque of the GTE engine that kills them. I had 2x W58s break at BPU power (400ish) before I decided to bite the bullet and go 6 speed. The 3rd W58 I had I sold to Josh on here who used it on his NA-T for quite a few years before it broke on him. I’m not sure about rebuilds etc as they only used to cost £200ish second hand so no one bothered. Now they’re going for silly money it might be worth it but they’ll always be a ticking bomb at 400ish bhp. Im not sure whether they can be strengthened?

ballsdeep Posted May 1, 2018 Author Share Posted May 1, 2018 Thanks I may look into getting a quote, it still drives and selects gear perfectly fine. When they do let go will I still be able to nurse it home? It’s just my luck, I Was planning to sell it in the summer too. Link to comment Share on other sites More sharing options...
ballsdeep Posted May 3, 2018 Author Share Posted May 3, 2018 Just had a quote to replace the bearings of £295 or £445 with them dropping the gearbox so I’m quite happy with that considering the price of second hand boxes. Link to comment Share on other sites More sharing options...
griffsplace Posted September 1, 2020 Share Posted September 1, 2020 Hey, did you get this done, did it fix it, who did you use, mine does the same so I am wondering what to do about it. Link to comment Share on other sites More sharing options...
