Broken Passengers Side Motor Mount Bracket

I tried a search on this, but today search is not working for my iphone... So bare with me.

My understanding to date is that the drivers side engine mount bracket is the one most likely to go. Of interest, when my engine was rebuilt a year ago, the passengers side mount bracket was broken, and welded, but not reinforced (they did the fix and painted everything before telling me).

One year and a high performance track weekend later (~2.5hrs hard lapping) and the passengers mount is again broken. It is in the shop, so i have not seen it, but i assume the weld is the location. Not surprising.

Fyi i am using heavy duty rubber engine and transmission mounts, so nothing too aggressive.

Any thoughts on why i might have passenger side issues when the drivers side is the usual problem? Rust is nil. I am wondering if this is a symptom of something more than "shit happens".

Either way, i will get a quick fix now, and get the i.e. drivers side plate just to be sure, and work out a passengers side reinforcement also. Any reinforcement tips for the passenger side?

Thanks for any help

You're talking about the bracket that connects the rubber mount to the block, right?

 

Find a later- style mount- Gordon's right, they're stouter.

 

But that is very odd- if it was mine, I'd start looking at how it failed.  I've broken a couple of 

driver's mounts, but never the passenger- even the earlier one...

I seem to be good at exceptions. Also had failure of both timing chain master link retaining clips....

Trying to find the common denominator here. Likely will see it when brushing my teeth.

The part on the front subframe

Is this what i think it is?

Reason #57 why i the wrong rebuilder was chosen. Not setting valves before running, timing chain master link clips, no pins in suspension links, missing bracket.

Should i also trust that the old oil pump shims in the parts box were not needed with a new pump and chain? (You dont need to answer that one...)

I am quite surprised the car still runs... Thank god someone else who knew what they were doing finished the work.

I'd get that bracket on there pronto, before the fan chews up your rad on hard braking. There are some other motor mount threads currently with pics and photo from shop manual on clearance. I'm a bit fuzzy on how high you'll have to lift the motor to get enough clearance to slide it in.

At some point you might want to pull the pan and check chain tension.

If that bracket is not installed under the pass. side mount, your engine may shift and the fan may contact the radiator.  That is why they call it a limiting strap (or bracket).

 

Simply jack up the car, put it on stands, then use a piece of lumber and jack under the oil pan while you slip the bracket into place.  You'll need (2) 13mm wrenches and an Allen wrench/socket.
