RE: W116 280SEL Advice please
G'day,I live in Moorooka,I've had a few 116's so here goes...
Re the sunroof,the motor is in the boot,behind the spare wheel,if the motor is buggered you can replace it with a window motor(same part) ,Tony Spinelli at german wrecking in Rocklea has them Cheap.There is a hex bolt sticking out of the winder motor bracket,if you still have the tool kit ,there is a strange looking bolt(sometimes it's clipped to the bracket) that fits on to the drive and is turned with wheel brace,if the cable is still good you should be able to open and close the roof manually.If it won't move ,there is probably dirt in the tracks and it's making it hard to move,soak the tracks with INOX,wd40 is too weak.
Re the noise,Replace the engine mounts,theres one each side and one on the trans.
Trans in all OZ 116's except the mighty 6.9 are all 4 speed.Make sure the tires are close to stock size ,revs are normal,wind it out to 200 and you'll find you don't even reach the red line.If the noise of the engine is intrusive,and you are really noticing it at motorway speeds ,the engine mounts have definately sagged too much,always make sure the exhaust is in good nick,if the resonator is too small (typical of cheap muffler shop installs) you will get really noisy operation.
Finally ,make sure the tappets are adjusted correctly and the timing chain is fairly recent.
