Well pulling the fuse and leaving them out for an hour had no effect.
However, of greater concern has been the large amount of white smoke when the car is on load from cold and the distinct lack of go, so with that in mind I decided to take a peek at the Turbo today. I started by removing the engine covers and then the air filter, which was when I discovered that the lower part of the filter housing is also the rocker cover The inlet and outlet pipes had a fair amount of oil in them, which looks to have been coming from the breather into the inlet, naturally I cleaned them. The turbo has a noticeable amount of sideways play in the shaft which I am concerned about. I took the vnt solenoid off to try to clean its inlet filter and check the hoses, all looked fine so I reassembled it.
From the Turbo I moved to the inlet manifold where I had seen some traces of oil around one of the inlets. It took me a while to get it removed, thankfully the TIS I have had some useful hints there. When I got the manifold off the ports were caked in black sludge (oil and soot), I guess 143k miles with an EGR does that. Still, it was when I got the manifold of that I found the vacuum feed pipe to the vnt solenoid was broken! The pipe was badly perished, so I've temporarily spliced in a new piece of vac hose until I can get some new hose and some protective heat shield.
Once all back together again I took the car for a drive and it feels better, but it's still not really quite right, time to test the MAF...
Cheers Ronnie, I wondered where the breather pipe ran to!
Hope to get my mitts on some decent vac hose today so I can replace the hose properly. Just glad my other life fixing Imprezas was able to help me here...I always keeps some lengths of vac hose in my emergency tool kit
I tried disconnecting the nav today and leaving it off for several hours to see if that would work. Nope.
Also found the radio/amp and disconnected the quadlock the reconnected it to see if the O/S speakers would come back. Nope.
I've looked at the ebay prices for the Mk 3 and Mk 4 nav units, they're fetching more than a decent Tom Tom, which seems daft seeing as neither is as good really. I guess I'll just remove it and see if one of my more electronically minded mates can see what's wrong with it, ditto the radio.
Back under the bonnet again, I failed to find some vac hose today, however I have tidied up my bodge, tried cleaning the breather filter (it need replacing really), and disconnected the MAF to see what effect that would have. Not a lot, still short on any real go below 3k rpm, I suspect my VNT maybe goosed
While under the bonnet I noticed that the aircon has been leaking from the connections at the pump, guess the 'O' rings were too far gone after all.
Took the car back to the place that charged my aircon, for them to take a look at the suspected leak...minor detail issue, couldn't see the leak for the generous coating of oil
It would appear that in my efforts to cure the Turbo issues last weekend I upset the rocker cover gasket and it's weeping quite profusely down the O/S front of the block
I pick up a new gasket set and a breather filter in the morning. Annoying really I had planned to fit the toe bar this weekend and then get on with finishing one of the Imprezas
I've made a right mess of this car lately
Well I've spent the day replacing the rocker cover gasket, and while I was at it I took the opportunity to replace the inlet manifold gaskets and the breather filter with new parts as well, as well as properly fix the vac hose I bodged in last weekend. I also had a go at cleaning the MAF film, will see if that made a difference.
Only finished the car at 9 this evening so I elected not to take it for a spin, just fired it up to check all was well, which it was. Tomorrow I shall drop the under tray and clean it off (plus repair a crack), pressure wash the engine to shift the oil spill and fit the replacement O/S front corner undertray.
Amusingly while I was collecting my parts from Coopers in T.Wells this morning the chap in front of me was buying a set of inlet manifold gaskets so he could replace his split manifold on an '01 530D, I gave him a few pointers based on my own trials and tribulations, and suggested he look at Real OEM for guidance (he said he'd already trawled the forums). Small world
