Oh interesting!! So I found a leak! Now fixed but the econo gauge is still wrong. Vac gauge steady at 16mmhg. Is that too low for a M117??

Oh that's inches of Hg not mm.... I'm keen to replace the half shafts and book in for a RWC. Hopefully they won't look too hard at the rear ball joint boots but if they have to be replaced at least I have options with the Ball Joint Dr.

It’ll be interesting to try this out! No permanent mods to be made & completely reversible.... No FD internal hump, no bridge, no internal grille, no concave lid.

Well that wonít work unless you mod the fuel lines & other stuff so shelves that idea for now!

Better news with the help of a mate all the way from WA we found the vac leak under the battery! And fixed the EGR, EZL & trans mode hoses which were incorrectly fitted or disconnected by the PO! And now the econo gauge works perfectly & presumably other systems too... I donít expect the EGR to be working after all these years but if itís blocked up Iím fine with that!

Replaced the HPFE solenoid block which was found to be seized or blocked up too. Just gotta love NOS parts if theyíre still ok! Now the RR strut has started to leak but at least weíre making progress! The low pressure light now goes out after I adjusted the cable & it even goes to high position! You can hear the solenoids working when sport mode is activated even if the switch light isnít working (yet to fix)!

Looking forward to finally replacing the gauges & giving her a more thorough wash!!

Sounds like you've taken a big step forward with the HPFE system, doesn't sound like too much more work to get the car back on the road more permanently.

Thanks Sean yes itís amazing what you can find if you go back to basics & trusty old methods! They were used for generations for a reason!!!

I am very determined to see my projects come to life so I canít give up!!

I would say yes but I donít know them personally. Keep in mind the factory made things to suit a wide variety of consumers & turbos chop up the sound waves regardless so they may always sound muted compared to NA or supercharged engines. The TT BMWs in the GT Class at The Bend were quiet compared to others but still had very good pace!
