Evening all,
Been a while since I’ve posted on here, been busy with work and that rounding off to a month off. So the car was straight up of jacks to refresh the engine bay and sort out a few niggles the cars had.
Problems were a wheel bearing that was so loud I needed ear defenders at 60mph!
An overboost limp mode issue I’ve had since I bought her last year.
And a worrying amount of filth in the engine bay.
So I’ll just stick the photos up for everyone to see. Safest to say the clamshell design of these cars is amazing. 3 hours work and I had the entire front end off and that was fighting with 14 years worth of corrosion. So I treated all the corrosion spots on the chassis rails with zinc phosphate and then painted over with a cheap tin of hamerite. It was only stone chip size so can’t see any repair anyway. And I wire brushed the engine block and painted that with engine enamel. The brackets were all painted up in the enamel as well. Gave me a good chance to flush out the cooling system and clean the intercooler again.
Quick one first though! After all the fighting trying to find the overboost/over speed code issue.... turned out to be as simple as a broken turbo to cat clamp! I can only theorise that the absolute complete lack of back pressure was allowing the turbo to overs spool and therefore cause the overboost.
Wheel bearing was easyier than I was expecting. I bought a whole second hand hub from a 1.1 Mitsubishi colt and sorted the bearing while the car was on the road. Made it a one for one replacement. Only problem is that both of the dust shields were completely rotten. Very annoying but I checked with my MOT inspector and he assured me that dust shields are only required to be fitted on drum brakes and the only issue I might run into is brake fade if I drive through a deep puddle then try to stamp on the brakes (or other situations like that)
So the car drives great now, but fixing the worst wheel bearing I can now hear that the other front one is going as it’s slightly noisy in the straight and goes away when I turn. But that’s no issue to change the other one when funds allow.
Have picked up a turbo under-boost code now but very intermittent 🤦♂️
Much better than an overboost condition as I can now drive the car at 70mph without it dropping into limp mode!
But that’s going to be a split pipe/vacuum line or loose pipe so I just need to have a hint about, and the vacuum line I may just buy a couple of meters and replace the lot. (Can’t be worse than my 535D that had about 6-8m of vacuum piping!)
I also wanted to get the manifold off and clean everything up but not a single bit would move, even with my impact, so I left it alone as I can’t be dealing with snapping a stud!
Anyway, enjoy.

To do list now, is the other wheel bearing. And I think that new shocks are needed at all corners so I might change the springs at the same time.
