Is my GT Engine supposed to be tilted?

greensmurf20 · 07-05-2003

hi all, have a 70 GT and just wondering my my motor is supposed to sit lower on the drivers side of the car than the passenger side of the car. do i have some messed up motor mounts or is this supposed to be like this for some odd reason? thanks in advance for answers.

It's supposed to be tilted toward the passenger side about 15° for air cleaner clearance. You may have reversed the motor mount brackets.

thanks gary, i went and looked at them after reading what you said the first time, and one is a little different than the other, i assumed they were the same.

Are the engine brakets different???? I always thought they were the same. The cross member for the engine has a high and a low tower to it, but I didn't think there was any difference in size of the mounts. May have to go look at a few pairs I have.

They are different.

opelspyder · 07-06-2003

Hmmm...I must have just been lucky the 4 times I have changed engines, never had a incorrect tilt problem. Thanks

greensmurf20 · 07-06-2003

yeah, wish i got as lucky as you...LOL. might explain why you really have to push hard on the passenger side of the hood to get it to latch, but not anymore thanks to gary asi will know what to look for when i put it all back together. BTW, the machinist should be calling this week to tell me to come get my opel stuff. then he cal tell me the news on my crank and i can get bearings and a head gasket from OGTS. it was funny when i dropped my opel items off because ther was one other 4 cylinder in there, which was ford and the rest were almost all big block v8s.

I have 6 motor mounts and two of them are installed. They are all identical yet my engine tilts significantly to the passenger side. I have put a 1/2" spacer under the passenger side motor mount and it is still tilting towards the passenger side. Does anyone know for sure that the left motormount is different from the right?
Thanks, Trent

soybean · 07-26-2005

Yes, the left (drivers side) is different from the right. I didn't believe it either until I rebuilt the engine last year. I have another engine crossmember out and will take pictures for you tomorrow morning when it is cooler. 90 + degrees now. Jarrell

Dmcbrass · 07-26-2005

Look at the OGTS website. No difference between left and right mounts.

petrieopel · 07-26-2005

I have been told by Opel GT Source that the two motor mounts are the same. The amount of tilt just doesn't seem right but I could be wrong. I have attached a picture of my engine after installing a 1/2" spacer on the passenger side. It is still tilted although not as much.

The motor is supposed to be tilted! Take the spacer out. The engine support cross member has different height towers to do this, all of the other parts are basically the same, although there is a slight difference between the left and right motor mount brackets that bolt to the engine, but it has nothing to do with the height difference.

I was reading this and reminiscing of the old days when Jared was a newbie here. My, now he is almost a 2000 post grizzled veteran!

Exactly what I was trying to say. The heat had me befuddled last night. I'll still take pictures today. Jarrell

GTJIM · 07-27-2005

The left and right GT engine mounts ARE different and the motor is suposed to be on an angle - have a look at the gearbox mount bracket too.

petrieopel · 07-27-2005

I was mostly concerned with the rubber part of the motor mount. I was wondering if the left and right are the same.
Trent

spdkilz02 · 07-27-2005

yes there are, OGTS has them they are the exact same on both sides

Dan-MI · 07-27-2005

I just replaced both mounts. They were identical in height. These came from OGTS and they said there was no difference in the right and left. The only difference in them was that one had a slightly longer thread on the top. From taking the old one off I knew it was harder to thread the driver side, so I used the longer thread on that side. But other than that there was no difference.

Opel calls them "damper blocks" and there is only one part number so they are identical.
Opel Part No. 684277

petrieopel · 07-27-2005

I apologize for not being more specific describing the damper blocks but I really appreciate all the info.
Thanks, Trent

GT engine mounts, rubber piece with bolt at top and threaded hole at base, are identical, right and left mounting brackets are NOT, due to engine tilt. All is revealed in my diagram . . . clear?

soybean · 07-27-2005

Here are the pictures I just took of the engine mounts, and the right and left mounting brackets. According to the tape measure (measured from the floor), the drivers side is 10''. The passengers side is 8 3/4''. The Damper blocks measured 2 5/8'' (Drivers side), 2 1/2 passengers side. Now these are old dampers that were replaced (pictured) and the engine cradle was pulled from my 73. The Damper blocks could now be manufactured identically since the difference was only 1/8''.
