If you have replaced the engine mount....a question
 
I'm in the beginning process of this, I got my car up at the top of the jack stands..or about 18 inches. I scotched (single blend )the front tires and removed the tray, then loosened the bolts slightly...just broke them to movement....and I thought this is not going to be that difficult....and then I tried to put some pressure on the pan to support the engine....it is so high I had to use my largest floor jack and a urethane jacking puck......and then the $#*&^% jack is in the way so I cannot work....tried it from the side and it is still very much right in the middle of everything.....any suggestions ??

Thanks in advance

Hey Dwight. I just did this two weeks ago. I used a car ramp I had. You know one of those angled ramps with a flat spot you drive up on? I put that directly under the engine and then I used a scissors jack, just like the one in your front trunk, on top of the ramp. If you use the factory jack it has a bump on top of it, so you might have to come up with something. Maybe drill a hole in a 2x4 to fit it. A hydraulic jack might lose pressure and leave you in a bad situation...

I have not done this one yet, but I'm planning to and read a write up recently that suggested that the scissors jack is the way to go.

Thanks
 
Will try the scissor jack tomorrow after work...did you guys use locktite on the bolts ?

mikesz 12-04-2014 04:25 AM

I have pressure treated "blocks". Maybe a foot to a foot and a half long maybe 8x8 and put the scissor jack on top of that to support the engine. Worked fine and I could get under to replace the water pump, thermostat, and front engine mount.

Here are my instructions ...
 
Install Front Engine Mount

As stated above a scissors jack to support the engine is the best solution. It's also the safest solution since it's a mechanical, not a hydraulic jack.

Happy Boxstering,
Pedro

No locktight. I never found a torque for the four studs. I put the studs into the body at around 15-18 lbs. torque the nuts to spec. Sorry I cant remember that and no access now

+1 Scissors jack
Use a piece of wood to distribute pressure point
Scissors also allows you to raise and lower motor while you work under there. You'll need every inch of working space to get your hands/wrenches on those bolts
Can't remember if I used Locktite. I'm thinking I did

Pdwight 12-04-2014 02:27 PM

THanks everyone, I'm off to busted knuckles time......LOL

Engine support bar from the top. Great to have in the arsenal as it comes in very handy and leaves the underside completely clear.

Pdwight 12-04-2014 04:01 PM

Just got 2 of the 4 studs out...can it be done without removing the coolant hoses ??

dghii 12-04-2014 04:54 PM

No need to remove hoses but you need to unclamp them from their holder just forward of the mount. You can maneuver the mount out by pressing on the hoses.

Krieger 12-04-2014 06:54 PM

Yes it can be done! I read on Pedro's Garage to lower the engine 3" to help facilitate removing the mount. I did this with no problems. The scissors jack is your friend. I also loosened the brackets on the under body for the coolant pipes so they could drop a little.

Krieger 12-04-2014 06:56 PM

Pedro posted his link in a previous post. It was helpful for me.:cheers:

Pdwight 12-04-2014 07:16 PM

Got it done.....whew....like building a ship in a bottle

Krieger 12-04-2014 07:30 PM

Nice! Now drive it like you stole it!

Pdwight 12-04-2014 09:18 PM

The old mount was holding by a thread,the rubber material was shrunken and gone for the most part. If I ever have to do this again I will definitely drain and remove the coolant hoses....they were the most difficult part of this job. I could not get a torque wrench on the top two bolts...I got it tight and it will have to do, I torqued everything else to the correct torque and the two bolts that go trough the center of the mount did have locktite on them...I used red since you have to have it out anyway to change the mount. I also installed the new rear control arms so as soon as my headlights get back I am set...the rear wheel bearings will have to wait until after the wedding.

Thanks for everyone's help

especially Pedro my old friend

Wedding? What wedding?

Porsche9 12-05-2014 07:05 AM

Just replaced mine this morning (my indie did for $80). I actually noticed that my shifting at times got notchy (engine was moving). Sure enough the old mount was shot with the rubber craked and falling apart. At the age these cars are my thinking is that if it has not been replaced it needs to be replaced. Shifting is now smooth as butter.

Pdwight 12-05-2014 10:36 AM

$80
 
A deal I would have paid $100 without blinking an eye.

I am getting married next week 12/13/14

My last time (I promise)

I want the car to look great for the going away car....lights from Particalwave in soon to finish it off.

Porsche9 12-05-2014 11:55 AM

$80 is not enough to get me to do stuff like this myself. Nice thing is my work is close to his shop so he gave me his Cayenne to get to work and then dropped my car off and took the Cayenne back I didn' even have to go pick up my car.

Congrats on getting married. Hope you are as lucky as I am. Been married over 20 years with no regrets.

Did replacing the rear control arms take care of the noise? Good luck on the wedding:cheers:

Pdwight 12-05-2014 06:35 PM

Dont know...have not drove it yet...lights are in transit

No. Im pretty sure that 15 is way too low. Pedros write up has the torque specs for the studs. They are pretty high, in the 30 to 40 ft-lbs if i remember. If you dont torque them to the right spec, they will pull out when you put the nuts on them and you will be in a world of ******************** trying to get a a helicoil in there. Be warned.

Pdwight 12-05-2014 07:56 PM

Those were easy
 
I torqued all those to 35 ft lbs per Pedro's instructions. I simply installed the 4 studs using a 1/4 inch drive 7mm socket until they bottomed out and were tight...then the nuts. The bolts that you never actually take out are the ones I could not get a torque wrench on. If the coolant hoses were removed it would be a pretty easy job.
