Kase Posted July 28, 2011 Share Posted July 28, 2011 (edited) Okay. I have had this oil leak on the front of the motor for a while now. I have changed every oil seal on the front of the block and the rear main seal (during clutch installation). The leak is coming from behind the cam shaft pully (driver side). Can the CVT be the problem? The last mechanic told me he swapped the two camshaft pulleys and the leak was still on the driver's side but I don't have much faith him. The motor runs great; just leaks oil. (Car's a 1990 2+2) Edited July 28, 2011 by Kase Quote Link to comment Share on other sites More sharing options...

(Car's a 1990 2+2) there are seals/o-rings on CVT cam sprockets . check on the backside of the sprocket . might want to put some dye in the motor and run it until starts to leak , use UV ( black light ) light to detect leak , if you can get one . good luck Edited August 19, 2011 by Domzs Quote Link to comment Share on other sites More sharing options...
Jehannum Posted August 19, 2011 Share Posted August 19, 2011 there are seals/o-rings on CVT cam sprockets . check on the backside of the sprocket . might want to put some dye in the motor and run it until starts to leak , use UV ( black light ) light to detect leak , if you can get one . good luck The O-rings are actually right up front. All you have to do is undo the 4 8mm bolts on the front of the intake cam. Be prepared, though, as there are springs under there, and they will shoot the damned thing off at you.

Jehannum Posted August 28, 2011 Share Posted August 28, 2011 front and back . You talking about the cam seals? There aren't any O-rings on the back of the intake sprocket. Quote Link to comment Share on other sites More sharing options...
Kase Posted September 1, 2011 Author Share Posted September 1, 2011 Okay. I bought new cam shaft pulleys and Gonna install them this week. The oil seals are new and it just had a complete head job including new valves and lifters. On the end of the camshaft where the pulley actually mounts there is a shallow groove about 1/4 inch back from the end and I thought that was for another o-ring but I was mistaken. Hopefully this works; think I might replace the oils seals again just for good measure. Quote Link to comment Share on other sites More sharing options...
