it is 4-6 bolts (2-3 for each tow eye iirc) and a lot of spot welds. If you can't weld best thing to do would be to get everything off (bumper etc) drill/chisel the welds then bolts the new one on and drive it to be welded, would be the least cost.
it would depend on garage doing mot, I was advised just to do the 4 bolts up 2 either side and use pop rivits to replace spot welds, went through test no trouble. Plus I had one for test last month and they rekon the cross member no longer comes under test seemed strange to me but they passed it and to be honest the back of it was all rotted out.
The people doing my mot seem good! They are picking out all the small details too, which is a pain as theres more stuff to fix, but i like it as i like my car to be 100% road worthy as i rely on it every day as its my only car!
Ill have to ring up local welders monday, see what they say. Then ring up mot peeps and book in for the free re-test they promised!
How bad is the rot?You can cut out the infected area & plate up if it's not riddled.
The labour charge is dear because of the stripping out involved,if you got the bumper off it would be a good start for them...
The crossmembers have holes in the top which let the water in,when it's fitted use these holes to squirt some waxoyl inside then put tape over the holes to keep water out.
You can protect the section before giving it to your welder with paint/stonechip etc. provided you keep a few inches away from the ends where it will be welded.You can touch the welds in afterwards...You can get stonechip in aerosols which gives a good finish & you can paint over if you want..
Have you tried a new (expensive) lambda sensor or a low mileage secondhand item for your emmissions problem?Or try taking yours out with a 22mm spanner and cleaning it with some carb cleaner & taking your car for a good blast before the test to clear the cats & exhaust out...
Found this guy on E Bay with aftermarket sensors for K10's,(Item number190304894755) I've mailed him to see if he's got for K11's as I want to try one on my car.Gotta be worth the £20 ish he sells for.
My crossmember was completely rotten, but was passed through MOT (a few days before i bought the car )
took it back to MOT gagrage to quiz them but they had passed it as it was was more than 15cm away from any safety brakes/ suspension parts
They put a new one welded on for me for reduced price £120
I dont know if they felt guilty for passing the car through the MOT, or sorry for me being ripped off with my car purchase, but i didnt complain.
