Do you mean the bolts holding engine to frame or bolts holding cases together?
A bit of love needed for sure. Have you tried Plus Gas penetrant oil, its absolutely spot on. Some of the mount bolts and case bolts were practically welded onto my 550, a 24hr soak in that and a bit of heat and not broke and all came out without necking off.flea bay number 202951224018EAN 5010352802202I was surprised how good it is, worth a go if youve heaps of stubborn ones to do Tom.
Engine to frame would be my guess Bryan. One of the engines I recently bought in the job lot has both front bolts stuck and both underside also stuck. I was trying to get them loose when I spotted someone had snapped a cylinder stud, N/S/R and in order to get the remains out of the cases they'd cut across the gasket surface and fitted a slightly bigger stud. I threw the cases away after seeing that, I tried to salvage the rest of the studs but they refused to come out even with a LOT of heat. BTW, the engine bolts wouldn't come out either, ended up drilling one out but it drifted a little, I was looking at how to fix that when I spotted the stud. Combination of both of those was enough for me to give up. Sometimes you're just flogging a dead horse.

I’m going to spread the nut with a sharp chisel next. Thanks for all replies chaps, even if I’ve already tried most stuff, one reply I might not have. The encouragement is great too.
Phew!! I haven’t worked this hard since I had a job 😂 (Attachment Link)
