Hi All, I have searched high and low for a thread on this, my apologies if it does exist. The intermediate cover is leaking on my 1990 UK spec TR, the leak is very slow but wreaking havoc with my OCD. It looks like I can remove the cover (after draining the gearbox) with the engine in the car. The problem is I can't find a gasket part number, maybe it's sealed with a compound instead? Anyone had any experience with this? I've attached an image of the leak location (the image I found is not my car). Cheers Spence Image Unavailable, Please Login
there is no gasket, only sealing compound but before you remove this cover you may clean all and put some silicone sealing outside. this mostly helps and when the engine is out for service you can do it right
Oh, so you're saying attempt to seal from the outside and see how it goes. I have a hoist, it looks like i can get pretty good access to it with the engine in, I'll have a go this weekend. Is there a sealing compound you'd recommend? Also a gearbox oil that works well in these cars? Thanks so much for then input.
I always use RTV silicone from wuerth ( not know if available in the US ). they also have clear silicone so you not see at first sight. in my competition I use castrol syntrax limited slip 75 W 140
Sealing externally never works' it just makes a mess. It is not that hard to remove the cover after all the long studs are removed. In my experience RTV is a poor sealant for that. Use Locktite/Permatex 518. It is the equivalent of what Ferrari suggests and being anaerobic you have literally forever to get the part in place. 75/140 is inappropriate in every way for a street car. Stay with a 75/90 or an 80/90 the way Ferrari and the oil manufacturers tell us.
