It sounds like a couple of more things we can try.We've spend an evening puzzling to get the 2,5" manifold in without removing the clam.
Has anyone managed to install it while leaving the rear clam on??
We've tried tilting the engine to gain space with the two lower engine mounts loose, but the centre line of rotation is too high to make this work.
any suggestions?
Unfortunately i had other things to do so i took the clam off which made getting the manifold & system on pretty easy.
I've since tightened my manifold bolts so you can get to them easy enough.
A couple of suggestions
1. do you have the original heat shield material lining the boot area on. You can get more room by taking it off
2. It may also be easier to take out the bolts from the head, offer the manifold to the head then put the bolts back in. This will give you a bit more room.
make sure taht the holes in the flange mate up to the head though. The end one's on mine needed elongating to get it to fit.
There's only one or two bolts / studs that stayed in. the rest came out with the nuts. Will try to get them out though.
I haven't tried to remove the heat shield as it seems quite ridgid.
I'll follow up the advice on bolt hole pattern check. It would be hars finding out the holes don't match and the manifold will need to get out after getting it finally in.
@rsg, I was hoping for such a moment: I don't know how I did it, but it's in.
