My passenger side motor mount is not fitting right (pictures)

Well I finally got everything together and lined up. However, there's something wrong with the passenger side mount. What can I do here? Slot the cross member so the mount slides back? What about the transmission crossmember? If I remember it's slotted. Would moving that take any stress of that mount? Or will everything settle into place once its running?

What part of that picture are you calling a problem?

If you look at the rubber on the motor mount (chevy) it is a little twisted.

Who's up rights are though-es?

I got them from you. Any suggestions?

you may have to drill out the cross member out just a little and make sure that when you first put everything in that it is all loose till you get everything lined up. Once everything is straight and in placer then tighten all of the bolts. Unfortunately I think all these cross members are a little different, and that makes it hard to have a universal part that fits perfect every time. If we need to remake that side I will just let me know.

Ya, I put everything in loose and then tightened the bolts and that was the result. I think it's off by about 3/4". How can I measure the exact measurement? I don't have any fancy angle finders or anything like that. Can you walk me thru it?

whoa... this looks familiar. With the engine on a hoist and suspended ever so slightly (to help reduce any drag), get under the rear of the car with a length of 2x4 or similar and see if you can lever the drivetrain forward. Can you shift into reverse? Is the shifter further back in the tunnel hole than you remember?

Mine did the same exact thing and I found that the transaxle mount allowed massive fore and aft movement when I wedged a section of wood between the spare tire well and the end of the transmission. Were talking up to a full 1 to 1.5 inches here!

The drivers side fit fine but the passengers was all screwed due to the soft tranny mount allowing the transmission, torque tube and engine to slouch back....especially when the front of the car is jacked up.

Check this out before any further progress. The CV's should be rather straight as compared to each other and perpendicular to the line of the drivetrain. If they are at an angle from the transmission to the wheel, this is a clue that the mount is lazy and you may need to replace it or upgrade it to a more sturdy alternative.

After looking at this picture a bit further, im starting to become rather entrenched in my previous opinion of your tranny mount. See the obtuse angle of the rear of the mount as it is? Now imagine if you could get the engine to move forward.... the angle would correct itself. The oil pan is also so much further back from the crossmember than I recall mine or others. It should be quite close to the crossmember...something like 1/4 to 1/2 inch away.

Loosen all nuts and bolts of the uprights so that the engine can be jostled around first. Then, if you can, hoist the weight of the engine so that it can be moved without a lot of drag. Then see if you can push the drivetrain forward.

The biggest thing is to engage the lock tabs of the torque tube to the lock tabs of the torsion tube at the rear. If these are far from each other....this is your answer.

Look into this and let us know!

It's susposed to rain for the next couple days and I dont have a garage. So when it clears up, I'll hook the hoist back up to see if I can get everything to move forward. Hopefully, thats the cause.

Thanks for the help!

I just looked under the car. The transmission and torque tube can come forward about 3/8". Would that cause that mount to be out that much?

Thats it? Regardless, you should move the drivetrain forward so the mounts sit happily. The max that it will all go will be when the lock tabs come into contact.

i had the same problem, it was an easy fix, my motor was not straight, i measure from inside water pump to inside and moved it to the driver side by an 1 and a half, then it fixed it self

I could not get the torque tube any further forward to lock into the tabs on the torsion tube. I put the engine back on the hoist and raised it up to take the weight of the mounts and I removed them. I tried prying with a 2x4 at the back of the transmission and the front as well.
I put a 5P transmission in the car; could it be that the transmission hanger is in a different place? My transmission mount will not allow any forward movement. I think I might have to slot the transmission cross member to engage those tabs. Has anyone else had a problem like this?

Thanks guys,
Spencer

I just found this picture on the internet; this is exactly how far my torque tube is away from the torsion tube. So can I rule that out?

I think we have figured out the problem here Boy's, Spence sent me a PM with a really good picture of the mount. On his passenger side the motor mount is mounted with the two holes at the bottom and the single hole at the top. Odd, but true, That seems to be the only way to mount it on his motor. Has anyone else run into this with their cars?

I think he has the Baby LT1.....

I have a 95 LT1... Anyway, I'm such a tool.... haha I removed a bracket that was beside the motor mount and flipped the mount.... as you can see it fits. I feel like such a jackass right now! I didnt even think of removing that bracket.

Now the oil pan is hitting the crossmember.... one thing after another!! Thanks Eric for the call that really helped me out. I knew something was up....

Thanks for the help!

My bad too. I see in your gallery you have alloy heads. The 4.3L V8 came with iron heads....
You can trim the front of your upright bolt thru's by 1/2 to 5/8" to clear the oil pan/xmember

you can trim the front of your upright bolt thru's by 1/2 to 5/8" to clear the oil pan/xmember

Wouldn't I just put a spacer under the uprights to lift the engine up? I'm not sure how much it needs to be lifted right now. I'll have to check tomorrow.

too a point, but the thicker the spacers under the uprights, the angles will change some. glad you found your problem...

i thought you meant the rear of the xmember hits the sump pan face....trimming the front of the uprights will give more clearance there is all....

I put 1/2" of washers under each upright and that still wasn't enough. The oil pan is hitting the steering rack. Does anyone have any suggestions besides the one I don't want to hear?

To be honest I recommend you go to summitracing.com and buy the poly mounts. They do NOT settle at all.

What does your oil pan modifications look like?
