When I installed the engine, I was torquing the big bolts on the frame horns and one of them seemed not to want to pull the full torque. It felt like the threads were going to pull so I stopped at about 80 ft lbs.  I think the problem was caused by the Kafer bar I put in that uses 1/4" plates between the frame horn and the trans bracket. This spaced the bolt out enough so I think the threads on the stock bolt are too short. This bolt is special with a large shoulder. Has anyone seen longer bolts available from some other VW or Porsche?  If I can't find a longer bolt, I'm going to have to put a helicoil in it. I've seen the kit for this but it and the drill is going to be big bucks. Does any one have experience with fixing this?  I thought about turning the bolt head down to get more thread length.

David (and all): both of us have experienced minor drivability issues post Soob-swap. David has experienced some clutch chatter. I have a little less of that maybe than him, but I've had some "shifting" of the gear spots while driving--even lost 4th once for a while. It just went away.

So I think my engine has been rocking ever so slightly under load. I was thinking that my home-built mid-mount transmission mount was the culprit, because usually anything I make for myself is just not quite up to professional snuff.

But now I think that maybe--just maybe--it's the fact that I almost certainly didn't put 160 ft-lbs on those tail bolts. More likely about 100. And since I turned the mount cradle backwards (again, looking for, and getting, just a little bit more forward tuck to the power train) I might have crushed the sheet metal on those a bit, making everything just loose enough . . .

so that my home-made mid mount's shortcomings are made manifest.

So I am thinking that if I crank on those big bolts quite a bit more, I might solve my shifty shifter problem, and Stroud might do the same for his chatter if he does the same with his torque wrench. 

 

That's what I'm thinking.

 

Could be a good link, Ed but my left rear tranny mount is toast and I'd put my money on that first in my case.  It always could be a combination of things of course.

I'm going to renew all my tranny mounts with good quality Stock spec mounts and then reinforce the whole shebang with a very stout rear engine mount with some stiff rubber mounts under a bit of preload. I have a pair of stock Soob mounts in nice shape from the donor EJ25 engine so I'll likely figure a way to mount them.

It's nice that we're all learning more about this stuff....proper torque this time at least.
