In my old S12 I had the bolts shear on the inlet side. The engine dropped a few inches. It didn't drop any further because the oil filter stuff itself in to the side of the amount. Made a hole in the oil filter though.

H'mmm I think I will try and bend a spanner tomorrow. If I cant undo them, they will have to stay stock

I've been using the s12 mount's for a couple of years without any problems.

Thats what I needed to hear! Thanks matey!
Did you find the same problem when installing the
DET ??

I just bolted the engine straight onto the s12 mounts,I didn't bother taking them out of the car.

Seeing that the CA18DET was a factory option in the S12, I dont see why one would be so worried about the S12 mounts. The things to consider though are: their age, the wear and tear on them, how they seem to hold when testing motors and placement of the CA18DET and how much vibration is felt around the car. S13 mounts are probably better due to age and the fact that the mounts themselves are different and in some ways use different materials.

i just used the s12 mounts on mine. Never had any issues. Just make sure all the mating surfaces dont have paint between them or paint/debris in the bolt threads. All this will cause less clampt friction force between the mating surfaces and the bolts will shear
