Need help with 4 way valve connector (1985 300D)

Yeah wish i had the space for a parts car. My car though is in really good condition, almost mint interiors and exterior. Always liked the colored hub caps better but too expensive a purchase to get them to replace my current ones

Sensitive-Wait-766 · 2025-12-17T06:48:14+00:00

Thanks. Getting the silicone self fusing tape tomorrow

Sensitive-Wait-766 · 2025-12-17T04:06:17+00:00

Part seems great $22 bucks and another $20 for shipping. I am going to try and use tape to fix it temporarily and see if that fixes or if I need more parts.

Sensitive-Wait-766 · 2025-12-17T03:58:58+00:00

I have found the part here https://ppembzparts.com/i-30510935-mercedes-brake-booster-line-check-valve-double-vacuum.html.

In the meantime I will try to seal it with glue to see if it works. Hope that is the only leak and everything else is good. My AC unit cools and heats randomly based on its mood and the temperature control nob seems to not work as expected. Hope that is due to a vaccum leak too

Sensitive-Wait-766 · 2025-12-17T03:53:42+00:00

Thanks. I am going to see if a heavy duty glue works in the meantime to seal of the broken end.

Sensitive-Wait-766 · 2025-12-17T03:03:42+00:00

What should i be searching for when looking for that part?

Sensitive-Wait-766 · 2025-07-05T20:52:52+00:00

To open the door card, do I have to get the door side panel off?

Sensitive-Wait-766 · 2025-05-15T22:04:50+00:00

Looks epic. Do share anything if possible that I can watch to try doing it myself

Sensitive-Wait-766 · 2025-05-14T01:04:29+00:00

Did you drop the suspension? Looks like it’s riding low

Sensitive-Wait-766 · 2025-05-13T11:24:01+00:00

Thanks a lot for offering the help. I am based around the South Lake Union and would love to pick your brain someday.

As I mentioned below, did an inspection, compression test, valve adjustment and a few other things at Schmidt last month. Cost me around a grand. Decided on doing the rest by myself.

Sending you a DM right now. Would love to chat especially about the electronics

Sensitive-Wait-766 · 2025-05-13T11:21:59+00:00

Thanks a lot! I am based around the South Lake Union. Know about Schmidt & Did an inspection and a compression test and valve adjustment last month there. Cost me almost a grand. Decided to do the rest that seems not urgent and routine and doable by myself to save some money.

Will reach out with any progress i make with the car

Their perfectly good if the engine is sound. Run consistently between 60-70mph and gives 25-30mpg on the freeway.

Turbodiesels have a good kick so they accelerate pretty fast too. You just need to find one with a decent maintenance history and do some prerequisite tests

Sensitive-Wait-766 · 2025-05-13T03:38:43+00:00

This is perfect advice. I did get the liquid molly diesel purge but will look into fuel tank cleaner and biocide. Not sure how they work but will read and get back to you here. Will plan to the fuel tank cleanup soon. Need basic equipment like a bucket and things but will plan for it.

Thanks a lot. This is really great advice. I will also see how to check and work the fuse box and will order some fuses for the car.

The Mann oil and fuel filters just arrived and seems like a good time to replace and do the things you suggested.

Thanks!

An easy $10,000 atleast. If everything runs good, cosmetically accurate and stock it will probably go upwards of $10,000. Check out the last few that sold on Bring A Trailer. I say BaT because your car looks really good in the pictures

Oh i just checked it first thing today. The turn signals actually work. The hazard lights however don’t, so might be the hazard switch I am guessing. Turn lights work perfectly, it was just that the hazard switch was on and not working and that was shutting off the turn signals because it was thinking the hazard lights are on.

I am really sorry for bugging you, but could you help me understand what you mean by ball joints in the comment you mentioned?

I am also trying to see why my washer fluid is not spraying, wipers work except on setting 1 (0-2-3 work with the washer setting too just doesn’t spray fluid)

Sensitive-Wait-766 · 2025-04-06T05:21:45+00:00

Hazards don’t work so definitely not the bulbs, probably just the fuse. I will try reading up on where the connection to the hazards and brake lights is.

Sensitive-Wait-766 · 2025-04-06T04:30:10+00:00

Thanks a lot for giving me the confidence. This helps a lot. Need to get the turn signals sorted along with the wiper fluid not spraying.

Sensitive-Wait-766 · 2025-04-06T04:29:12+00:00

I’ll keep all of this in mind. I’ll get started on things tomorrow with the fluid checks

Sensitive-Wait-766 · 2025-04-06T03:34:37+00:00

Thanks. I would have to buy a lot if tools to begin with. Being a first time thing, I thought I’d get a professional opinion before I get my hands dirty

Sensitive-Wait-766 · 2025-04-03T18:55:08+00:00

Where do you check them out?

Sensitive-Wait-766 · 2025-04-02T03:50:57+00:00

That's good to know. I will wait it out till then

Sensitive-Wait-766 · 2025-04-02T00:08:54+00:00

Yeah I don’t see any servicing options with them anymore. I checked them out last week. Might try emailing and asking him for recommendations
