By far one of the cleanest Z3M's for sale. Worth every penny and every nut n bolt has been refreshed.

Or if anyone is local to Basingstoke I have about 6/7 sets in the shed. You can Paypal the money to Mazza and come collect.

She's lovely mate, welcome to the very exclusive club.

That's very useful! @GazHyde sticky :D

When rebuilding the subframes and installing, this is what I do the diff bolt too.

That's the power for the injectors and manifold sensor, Can either pop that off or leave it attached.

Undo the two 10mm bolts holding the fuel rail in place, you can tilt it over for better access. Or even lift it up slightly, just holding down the injectors on 0-rings.

It wont be leaking air, it will be sucking air in. Remove that manifold cover with the two 10mm nuts and you'll have clear access. 10 minute job max.

Works the other way round during normal running mate, when we smoke test we do a positive pressure test where the smoke blows out, when the engine is running its running the opposite under a vacuum. Still stands this could well be your issue.

Welcome to the club mate, we need a picture or we wont believe you :P

It is doable, not too difficult at all, I warm the connections up with a heat gun and they clip together no problem.

10x NEW GENUINE BMW HEX NUT WITH PLATE AM7 ZNNIV SI 9905541 | eBay

They're not that expensive, at most a couple quid. The copper nuts are exhaust nuts so they'll be too big.

This could well be the cause of all your issues. you'll be loosing vacuum and sucking air in! I think they're M7 nuts using a 11mm socket, very BMW specific.

Just for info, this will suit any M52 and M54 variant Z3.
