Engine mount failure...fixed
Oops, maybe the pinto has a bit more power these days!
Broken the offside engine mount, not failed at the weld, but about 1" down from the block. Its the mount which has all the tensile force
on...
Another job for this afternoon! Was hoping to go out for a blat seeings a sits so nice outside too!
I'll post a piccie or 2 later...

We had an engine mount failure in the stock car and discovered it was caused by a fault in the clutch and accelerator pedals. With the engine running
if you pressed the accelerator pedal to the floor and let the clutch off the floor at the same time it broke the engine mounts  Hope this helps
Cheers

So thats what I have been doing wrong!
Was quite suprised that it failed. It was a piece of 25x25x1.6mm box. Think I'll make the new one from 14swg!

I used 10g on mine, maybe overkill, but it has the weight of a V6 hanging on it, :-) and it ain't broke , (yet)!!! Cheers Ray

That's quite a weedy engine mount, not surprised it broke, 10gauge or 3mm would be better suited. Made mine out of 50 x 25 x 3 box section.
DO NOT PUT ON KNOB OR BOLLOCKS!

I usually think in terms of 3mm for engine mounts. I've got a big sheet of it, and cut pieces off and weld them together as required.
Another approach would be to use the 1.6, if convenient, and strengthen it with extra plates

That's how I made mine, very strong indeed.

Made a new one tonight from 3mm wall 30mm tube. Looks a darn sight more substantial... Just need to weld it up now and make one for the other side
too!

at a guess, using CO2, hence the spatter (mine is the same, I use it too) get a can or two of anti-spatter spray, makes things much easier! (only a
quid a can)
On the original mount, it was the weld that started the failure by the way, it cracked from the heat affected zone, pretty normal!
