iain Nicholson Posted March 26, 2008 Report Share Posted March 26, 2008 I have an annoying small oil leak on my S3 Turbo, which I suspect is coming from where the exhaust cam housing mates to the cylinder head. When hot every few minutes a tiny drip of oil lands on top of the exhaust manifold and obviously smoking occurs. I don't think its a very serious leak, but experience tells me that it will probably get worse and it needs sorting. As my cam belt is due for renewal I was wondering wether it is feasible to lift off the exhaust cam housing and reseal the two mating surfaces with a suitable silicone gasket? Is there sufficient clearance between the cam housing and the glassfibre sidewalls of the engine bay to remove the housing and perform this task without major surgery??!!! Regards Iain Nicholson.

th4neuk Posted March 26, 2008 Report Share Posted March 26, 2008 My old car was done by PNM for this problem and afaik he did it all in situ. It was and 89 turbo so basically the same ish.

trackmagic Posted March 27, 2008 Report Share Posted March 27, 2008 If you have access to a vehicle lift it will be a whole lot easier to remove the cam towers. Just removed mine on 83 Turbo and it was a day and half job. Have fun, Jeff Quote www.espritturbo.com Link to comment Share on other sites More sharing options...
910Esprit Posted March 27, 2008 Report Share Posted March 27, 2008 This is a fairly common problem. Dont know if its possible with 'sidewall' in place but it will be much much easier with it removed and you will have more access to do it properly. (you only want to do it once!) NB silicone is not used for the cam tower to head - an anaerobic compound is used on your vintage car. Dont forget to measure your valve clearances before you start as this will also be a job to do at the same time... cheers Steve Quote Link to comment Share on other sites More sharing options...
peteyg Posted March 27, 2008 Report Share Posted March 27, 2008 Hi Iain, Shouldn't be a problem in situ but just check that the leak is not coming from the cam cover rather than the cam-carrier/cyl head joint as it's a much easier fix and they are prone to leaking! If it is the carrier, you'll need an anerobic liquid sealant. Pete Quote Pete '79 S2 LEW Miss September 2009 Link to comment Share on other sites More sharing options...
