is my power steering pump bearing damaged/ worn out?

excuse my muscle spasms, Im still trying to locate the random intermittent rattle sound coming from my engine and Im slowly going insane.
(I just spend another 400€ for an oem DISA valve, being sure it was the last potential source of the noise. It was not -_- )

So now I replaced my (only one year old) belt tensioner and checked all other accessory pulleys while I was down there.

And while doing so I noticed: the power steering pump is suspiciously loud, when shaking it clock- and counterclockwise.

There is no play forward and back though…

could this be my problem?

engine health after 175k km

service history had a 50.000km gap, but the cams dont have any scratches on them.

I guess thats a win

does anyone have a picture of a dark blue Z3 with a red soft top?

Im 98% certain on getting a regular black soft top replacement for my montreal blue roadster.
But just curious what it would look like to have a blue on red combination.

is 650€ fair for this soft top?

Im potentially buying a used replacement top for my M44 1.9l from this imported donor Z3 M.

The seller is asking 650€.

A decent soft top fabric in germany is 600€ at least and this would save me some of the hassle required to install it.

what do yall think? good deal or no

replacement for M44 throttle body gasket? (13541739809)

Has anyone got a workaround for the discontinued throttle body gasket on the M44?

original part number is 13541739809

I want to replace it for a potential air leak, but dont want to take it out before I can find a replacement, because I might damage it and make it even worse

the measuring in the pictures is in cm btw

M44 throttle body gasket discontinued?

Does anyone have an alternative to the oem M44 throttle body gasket (13541739809), since its no longer available and there are no replicas anywhere?

BMW doesnt even list the dimensions for you to find a solution -_-

M44 fuel hose discontinued

Im redoing my fuel injectors and wanted to replace the 40mm fuel hose connecting to the fuel rail.

BMW lists the part 13 531 748 684, number (4) in the picture as no longer available and doesnt link a replacement.

Due to the high temperatures under the intake, its not just any other 8x13 fuel hose.
BMW calls it „FPM“ which is DIN ISO 1629 high temperature fluororubber material.

What part number should I replace it with?

Injectors for M44 (Z3/318is)

I wanted to get new injectors for my M44, but the only place selling them is BMW themselves for almost 300€ per unit.

I contacted some shops about rebuilding my original injectors, but they said they couldnt do it.
They are missing the protocols and adapters for the machines to check them properly.

Guess you could try and rebuild them yourself, but how could you check if they even work correctly after all?

ultrasonic bath and new O-rings is what I could do myself. What liquid for the ultrasonic machine should you use for these old injectors though?

My car suffers from a shaky idle. Its not bad, but its bad enough for me to worry about it.
Fuel consumption is fine, but you need to drive a long time before the fuel smell in the oil goes away.
My Z3 is very prone to have the oil smelling like fuel. Its way more sensitive to this than any other BMW Ive driven.

so my thought is, its dirty old injectors causing an incorrect fuel mixture at times

door sill maintenance - rubbing plastic causing surface rust

just removed my door sill trim, because I noticed the plastic rubbing on the paint and causing rust already.

I scraped off all I could see and put some rust converter on it. Gonna order some touch up paint and protective film to prevent this in the future.

While the trim is off, I noticed access holes to the inside of the side skirts.

Is this the perfect time to spray it full of fluid film?
Or are these drain holes where water needs to flow freely? (talking about the larger holes seen the first picture)
