briggy 0 Posted February 5, 2006 I have a 1995 M reg VR6 with 117,000 miles on it. Original clutch & timing chains / tensioners. I've been investigating several noises recently and I think I've got to the bottom of one, plus discovered some other problems. 1. A "wooot" noise when setting off in first (about 30% of the time), somtimes when changing to second (about 5% of the time) and very rarely when changing to third. It happens as I take my foot off the clutch. It's been like that for ages and I've always suspected the clutch. The other day, the clutch slipped. I floored it in 3rd at 60mph. Normally a very pleasant experience, but this time, it took off, then I lost power but the revs continued to rise, then regained power and all was well again. Sound like a slipping clutch? 2. A whining noise when the engine is cold. The pitch increases with the revs. It's not the PAS pump, the alternator or the water pump. I know this because I disconnected the aux belt and the noise was still there. Apologies for going over these 2 points again as I've already posted about these noises. Now I've noticed something else : 3. Mayonnaise on the oil filler cap. Does this always mean a failed head gasket? The photos attached (hopefully) show what I think is oil leakage from the engine where I guess the head gasket lives. These are taken while standing by the driver's side wheel arch looking across (& down) the car. Can anyone think of a good plan of action? I'm thinking a disappearing car and an insurance claim. Only joking, but I can see this is going to hurt my wallet pretty badly. I still owe £3000 on the car which is worth £4000 tops. I'm also moving house next weekend with a huge mortgage increase. To top it all, I came in to wash my hands and found there's no hot water - the central heating has packed up. Not looking for solutions to all life's problems, but some advice on how to get my car sorted would be really useful just now. Cheers, Briggy Quote Share this post Link to post Share on other sites
Trig 0 Posted February 5, 2006 Ok, i'm not sure about 1 or 2. Could 1 be the fuel pump maybe?? 3 might not be anything too bad to worry about. Do you drive short distances in the car a lot? Mayo can occur when the engine/oil doesn't heat up properly and you get condensation. Taking the car on a really good drive and getting the oil nice and hot may solve this... Also you don't seem to have attached the pictures, whack them up & it might give us a bit more of an idea. :) Oh and don't worry about the cental heating, you're moving house remember! Also dude, you probably should have continued on your previous thread: http://www.the-corrado.net/.archive/forum/viewtopic.php?t=36648 Quote Share this post Link to post Share on other sites
briggy 0 Posted February 5, 2006 Ok technical problem with photos now sorted. Wasn't sure if I should continue my previous topic as I was talking about new stuff too. Figured that some people who may be able to help with new problem wouldn't read an old subject unless they'd previously been following it. Sorry if this was bad form.

briggy 0 Posted February 8, 2006 Not exactly hot topic of the day judging by the number of replies, but I thought I'd post about the progress so far. Been to Vince at Stealth Racing. I do NOT have a faulty head gasket. The mayo is caused by condensation. This itself is caused by short journeys. Only gets to 76C when driving home from work. Makes sense in principal, but makes even more sense when you consider that it's only started since I did an oil change myself. Imagine all that lovely cold air coming in through the open oil filler cap while I'm draining the sump. Of course normally its effectively sealed, hence why there's normally no mayo. Gave it a good thrashing on the way up there and guess what? Less mayo. Got home and guess what? No mayo at all. The oil around the seam is normal. Mine just has a dark line, but no oil trails running down. Phew. The clutch is making the wooot noise. The bite point is still very low which means there's plenty of meat left on it. He told me not to do anything about it until the timing chains are done. Currently on 117,000 miles so won't be that long. The whining may be caused by the timing chain tensioner hydraulic bolt. We think this is on its way out, therefore struggles to pump cold, thick oil. As the engine warms up & the oil thins, it's fine. This means that it's not tensioning the tensioner properly when cold. Ouch! I've got a new one and will report back when it's been fitted. Cheers, Briggy Quote Share this post Link to post Share on other sites

double-6s 0 Posted February 8, 2006 good news then bud. :) and even better news is that the solution to your mayo problem is to go out and give it some welly!!! Quote Share this post Link to post Share on other sites
briggy 0 Posted February 12, 2006 Changing the hydraulic tensioner bolt hasn't cured the problem. Out of ideas now. Cheers, Briggy Quote Share this post Link to post Share on other sites
edd 0 Posted February 13, 2006 regarding clutch noise try a search quite a lot of us who have/had this noise. Mine went after stealth replaced clutch. Quote Share this post Link to post Share on other sites
briggy 0 Posted June 12, 2006 It looks like the woooot noise was the clutch release bearing. I've now sold the Corrado but get the same noise on my new car! Fortunately for me, this is under warranty (BMW 330 coupe) so I've dodged a very large bullet there. Mechanic diagnosed the noise straight away when he heard it.
