Hidden rust...
« on: 11 August 2021, 02:59:05 PM »
I have a loss of power steering fluid.  I took the bumper off to check the cooling loop, but that's OK.  Removing the other underbody panels to look underneath, found a lot of wet areas which require further investigation.  But there was small bulge in the front of the metal bumper.  There's rust inside which has swollen.  A quick prod and a hole appeared... :(

Trying to remember where I've hidden the Hydrate 80 ::)

I tackled the inside of the rear wheel arches earlier this year. There was quite a bit of rust on both, mainly on the part nearest the rear seats portions (that are hidden behind the plastic liner). I started by pressure washing them to get rid of the surface dirt...  and then found I had a wet carpet! The pressure washer had blasted through. Cleaned them up, lots of Hydrate 80, then use aluminium tape as a former from inside then got the isopon out. Didn't need to be pretty, just functional. Finished it all with a liberal coating of Hammerite.

I did my rear wheel arches 3 or 4 years ago.  Fortunately, they were unperforated.  Much the same treatment.  Hydrate 80 and Hammerite.

I think I multiple problems :(

There's an oil leak which seems to be from the crankshaft oil seal.

There's so much oil around, I can't see any leak area for the power steering.  It may be leaking slowing from the steering rack.  The bellows are completely shredded. :(   The good news is that the power steering cooling loop is fine.  I may give it a coat of Hammerite while it's exposed.

A better view of the carnage that is the steering rack bellows.  The wetness beyond the split suggests that the rack seal has gone. :(

Put Hydrate 80 on the rusty bits of the front subframe.  Some Hammerite over that this afternoon.  Bumper back on.  Then off to the garage for the heavy work.  Iím getting too old and arthritic to do a lot of pulling and lifting.

All back roadworthy so that I can get it to the garage for the steering leak to be fixed.

Had another look at the oil leak and it seems to be leaking in many places. :o  Either the breather is blocked, or the pistons are letting by.  I can't see the cam cover, crankshaft seal and other bits all starting to leak at the same time. :(

Joe is very busy, but I'm in no hurry.  The car goes in on Thursday.
