Did you manage to get your gearbox/clutch problems sorted mate? Crackin' looking car.
Yeh I did, sorry never updated the thread about that did I.
The release bearing had packed up making it abit of a struggle to drive. So it was booked in for a new clutch at a transmission specialist. When the gearbox oil was drained they found some small pieces of metal, so it was completely stripped down. A new bearing was required along with a seal.
I got the car back after they'd had it for 3 days and was very happy. But one cold morning I was changing from 4th to 3rd at about 50mph and was met with some resistance. I found it would only do it for the first 4 miles after setting off at 5.30am in the morning.
So I was straight onto the phone to the transmission specialists telling them about my concern. They said that it was very strange and every part had been inspected thoroughly and there were no other signs of wear apart from the parts that were replaced. Now at any old garage I would be a little dubious about what they were saying but as my Dad has known the owner for 10 years I did believe what they were telling me.
I had wondered if it could be the oil, as it only happened when very cold as if the oil was too thick and causing the resistance. So I asked them what oil had been used and he showed me that their system said to use 75w90 on the RS172 2.0 16v. Which is obviously the wrong grade.
I got myself down to Renault bought 5L's of ELF 75w80 and did the change myslef, did the engine oil/filter whilst I was in the pit.
Since then I have deliberately taken it out when cold and the gearbox feels tight and smooth for every gear change. I am 100% happy that there is nothing wrong with the gearbox, but I would advise people to check what oil garages are putting into their 1*2's.
