The doom blue Passat - braking for parts

  • bunglebus changed the title to The doom blue Passat - rockin'

Why is it some jobs escalate? All I was going to do was find out which of the injector leak off pipes was causing a whiff of diesel in the car (a regular and very easy job), but they all looked dry. However taking the engine cover off reminded me that I should actually replace the rocker cover gasket that's been weeping for years and has been "in stock" for months. But of course I dropped two of the domed washers into the depths of the undertray, and while one was visible and retrieved with a magnet on a stick, the other was nowhere to be seen. Damn it, I'll have to take the undertray off, and if I'm doing that I might as well change the wheelarch liner it attaches too (also in stock for some time) and devise a way of preventing the captive clips from falling out every single time I try and put the undertray on, and all that means I can also access the washer bottle to reseal the pump that's been leaking ever since I had the cambelt replaced!

However - on jacking the car up I found the elusive washer, which was a bit of a relief!

Here's what a 275k mile VW TDi looks like with regular 6K mile synthetic oil changes

Oh and I found the leaking pipe on startup...

I'd noticed my rear pads getting a little low a while back so I ordered Brembo pads and discs (discs didn't look bad but I'd just rather replace the lot for the price difference).

My mate just moved to a house with a double garage so that was ideal for keeping the rain off.

Funny how sometimes you set out to do a job and realise there's something else wrong - both sides had one very seized slider in the caliper which took a bit of getting out. Sanded and copper greased them but I've ordered a new set as the galvanising has clearly vanished off them.

They must have been causing the brakes to drag a bit as the car seems to roll much more easily now, the slightest gradient and it's away.

Last changed in March 2020 so they've not done too badly I suppose

Having done the rear brakes mere days ago (!) I wasn't too amused to get out and smell something unpleasant and lots of heat coming from the OSR wheel. Oh well I've got new sliders and carrier bolts to fit anyway

Poops

Oh well I'll clean and grease the originals again. Disc definitely looks like it's got hot

But everything seems free, sliders, handbrake mech etc. Carrier looks a bit crusty though

So I ran a file across the contact points, did the other parts the pads touch after this pic too

Still feels slightly tight after refitting everything, I wish I'd actually found a cause of the problem. Could be the piston but this side had a new caliper in the not too distant past.

Might as well look at some other bits then, got a whiff of diesel the other day which usually means the bleed off pipes are leaking - they look OK but there's oil all over the rocker cover, only just changed the gasket! Bet it's those breather pipes - cover left off to diagnose.

Might as well fit the new plastic dipstick tube then - old one crumbled to dust so that was fun trying not to get any down inside the metal guide. Bits can live in the undertray until the next oil change!

Oh and I found the bracket that holds the engine cover just about to fall off, no idea how the nuts came loose but I nipped them back up

Bleed off pipes done

I think the oil leak may have been me, I had this clamp around the bracket as well as the pipe rather than just clamping the pipe. Changed it now so I'll keep an eye. I don't like the clamp on the other pipe so I'll change that for an original type one or a jubilee jobbie

OSR caliper still getting hotter than the NS. I'll wind the piston in and out a few times, if that fails it'll be another caliper. Bloody pattern parts 😐
