The 964 has been a little finicky lately (exhaust leak, fan bearing, now this). I just picked it up from the exhaust shop to fix the leak around the new sport cat. After getting home I opened the boot and found that the engine carrier is cracked. Is this just an odd coincidence? I added a qt. of oil last week and didn't notice it, but I suppose that it could have been there. I also haven't noticed any change in vibrations or shifter feel.

I'm just turning 70k miles. The car has never been tracked. I drive it hard, the previous owner was an older fellow who drove it quite gently. Is it possible to have sheared from such average road use?

And now, what is this going to take to repair? (gulp) Is this an engine-out service?

*edit*
I'm just realizing that it definitely wasn't the shop - I noticed the tailpipe sitting low this morning when I brought it over to them. Of course it would be low if the engine isn't supported on the rear right side...

No need to drop the engine to take off the engine carrier. Just support with jack and then take off the rear engine tin. Take off primary exhaust. Not too difficult.

Interesing break - I've never seen it there.

Stock mounts?

Indeed - stock mounts. It looks like an excuse to go for the Wevo's along with Rennline's reinforced carrier.

I've done TWO of the Rennline engine mount reinforcements and would HIGHLY recommend them, nice piece for the $$$$$$$$.

Looks like it broke in a similar place to LuckyP's:

However Pete wasn't so lucky as his gave way while driving on track!

Strange...could the stock mounts have been so bad that they generated some kind of strange stress to the carrier?

DWS964

Does the pulley have to come off to unbolt and remove the carrier? AC Bracket?

I think this is on my list. When changing my motor mounts last weekend, it seemed there was a bit of corrosion and/or stress (paint was flaked off and rusty at the welds) at the ends of the carrier.

Hi Boxsey- thanks for posting the link to Lucky's break. It looks like the identical spot. His description makes the replacement sound much more reasonable than I was anticipating too.

As Duck says, it's not much more of a job than changing the motor mounts. Mine was taken off, the Rennline gusset plate welded on, the whole thing powder coated and put back on in just over a day. Engine was supported by a jack stand while it was off. As you've got to buy a new one you can get it all fixed up with the gusset plate before you swap it.

p.s. I guess you've put a floor jack under the engine already since it's currently putting a strain on just the one motor mount at the moment?

tgage

1. Jack up the car and support with stands
2. (I find it easier to remove the rear tires for leg room)
3. Remove the primary muffler
4. Remove heat duct
5. Support engine with lift
6. Unscrew engine mounts from below
7. Remove 10mm and 13mm bolts supporting rear oil line
8. unbolt primary muffler support
9. unbolt engine mount bolts (you may need a long extention, they are torqued down pretty well

I'm just doing this from memory so may have added or removed a few steps! I think the most troublesome part of this job is putting the primary back in (now you have a good excuse to swap that out for a primary bypass) and unbolting the bolts for the engine mount.... may need to visit harbor frieight if you don't have a long bar...

Good luck!
