3.6L Timing chain tensioner question
 

Need to replace the gasket for the timing chain tensioner on the passenger side of a 1994 911. Is there anything I need to look out for when I remove the 2 nuts and the cover? Is the spring going to fly out or is it just a straight forward job to do? Thanks

Nothing will fly out at you. Gasket replacement is straight-forward remove and replace, installation the reverse of disassembly,etc. Have the Bently manual handy, though, and Wayne's book for reference.

You should inspect the condition of the chain ramps and replace them if they are too worn. Also inspect the tensioners to make sure that the pistons are no extended too far towards the chain housing. This indicates a worn idler gear or arm. You don't have any tensioner noise at start-up, right?

The only reason for replacement is that it is just leaking a little bit. There is no chain tensioner noise at start up.

The gasket is easy. It is just a good idea to inspect the rest of the pieces while you are in there

I'll definitely check things out when I have it apart. Thanks for the information.

For a 1994 3.6L engine you can change out the timing chain tensioners and gaskets without dropping the engine or opening the timing chain housing. On the left side it is right behind the distributor. On the right side it is on the bottom. When unscrewing the two nuts the pressure should be released before the nuts come off. If not you can easily hold down on the spring loaded cap until the nuts are taken off. The bottom tensioner and cap will allow some oil to drain out so have a small catch pan under the tensioner. Make sure you watch how the tensioner comes out and reinstall it the same way. The plunger with the hole always faces out toward the caps. Inspect the tensioners for wear. Do not rotate the engine with the tensioners out.

Good luck
