MOT fail corrosion

[brianw]

I have just had my CDT fail on the following: :eek:

Nearside Rear Suspension component mounting prescribed area is excessively corroded outer sill (2.4.A.3)
Offside Rear Suspension component mounting prescribed area is excessively corroded outer sill (2.4.A.3)


Typically on getting home I could not park anywhere near the house so have been unable to take a look yet.
It is the 'outer sill' bit that has me stumped. I thought that was the part beneath the doors and i suppose including the jacking area.

Has anyone else had this. I thought the sills where reckoned to be pretty good as a rule on our cars.

It also failed on the smoke test but the engine was cold when i took it in so am hoping a bottle of forte and italian tune up would cope with that.
It is the corrosion that concerns me.
I have always felt pretty blase on that front I guess.
Perhaps it's time to check guys.

Update:
I have just been laying in the gutter in the rain to take a look.
There is a hole on the underside of the outer sill each side near to the rear jacking points. The areas have been marked in crayon. I have not been able to get under properly to see if anymore areas are marked but from the wording I am hoping this is it.

Yeah I had this last year on the n/s rear which I cut out & welded new metal in, finding good enough metal to weld too is getting harder to find :mad: and this years MOT got advisories for the same on the o/s and two other areas for corrosion, I think that it will be it for me, I'm not prepared to chase the corrosion as I've done when I was younger, the body isn't willing anymore.

I spray through the car body's drain holes with a 360 degree lance spray of cavity wax every spring and autumn. Hopefully, that should keep the tinworm at bay!:shrug:

Yes that is the same location as where my problem is.
At the moment the holes are about the size of a ten pence piece but who knows how big when cleaned up.
I have in the past done a lot of welding on a transit i had and landrover. All done with an arc welder which was ok on the landrover chassis but pretty awkward on the transit.
Really need someone with a Mig for this.

I hope it works for you.
And to think i gave away 2 gallons of waxoyl and a sprayer that had been in my shed for years shortly before i got the 75's.
I had not felt involved enough for previous cars to use it!

Yes that's the trouble, by the time you've cleaned the holes up & cut out the rot they are three/four times the size, The rot/thin metal went up to the very edge of that area :mad: by the time I'd finished, all new metal welded in & new jacking pad and schultz painted.

Yes a MIG welder is a must. lying on your back welding upwards 6 inches from your face is a lousy job to say the least.

I use this for the suspension components:-

and clear for anywhere that it might be seen.

The area certainly does grow when you start cleanup.
I recall on aforementioned transit rhat i found a small hole right under the rear sping hanger. While a mate was dispatched to pick up a spring hanger i carried on cleaning up - by the time he got back i needed an adjacent outrigger plus another piece that I cannot recall now.
The initial hole was just the size of the screwdriver tip i was checking soundness with!

Caught mine in time:o https://i.imgur.com/aE4vhjRl.jpg
There is a cavity behind the liner, where water & mud collect. If not cleaned regularly, rust starts & moves along the sill:duh: As previously said, I've sprayed into all cavities & clean often.:cool:

I have had to weld my 2002 ZT sills this month bought the car last December with full MOT with no adviseraries think the MOT test must have been dodgey

I bought two repair pannels for a Mercedes Sprinter outer door sill
1995 to 2005 i cut them in half and used them on all four corners the profile of these small sill pannels was close enough to the oringnal sills and they only cost £15 pounds each from ebay
