Mechanicals / Re: What oil to use in 2024

Last post by daantjie - Today at 03:22 PM

Well "colder" and "cooler" are of course relative.  Our friends in Edmonton will consider -40C colder

If your ambient is above freezing (0C) then you can run easily 10w or even 15W at the low end.  I run 20W-50 good old  Castrol GTX in my 6.9 here in Vancouver year round but I never drive it in Winter but we see nowhere near the low temps they see in Alberta and such.  That's just stoopid cold in anyone's language...

I used to use 10W40 semi-syntheic for M110

Mechanicals / What oil to use in 2024

Last post by mrkozzy - Today at 02:16 PM

Apologies for not spending too much time reading old posts on the topic.
Its 2024 and things (oils) change hopefully for the better.

Havent had to worry about oil type for years.
car got serviced regularly by the same mechanic and he took care of the type of oil.
Now I and the car are in another part of the world with a much cooler/colder climate.

I want to get the oil changed and put the car away for the winter.
M110 engine.
What to ask for?

Mechanicals / Re: All brake light bulbs?

Last post by mrkozzy - Today at 11:57 AM

Did this a couple of years ago.  Check out my pictures in the link below.  I posted on this back at the time.

All the LED's are are straight swap depending on the purpose. (eg: indicator, stop, brake etc)

Correct that the indicators need a relay. This can be purchased to suit the globe type from the same source.

(If they don't have the relay, find a better supplier! - someone who knows whats required.)

What about the other lights? Are they all the same? Meaning could I place in other 21w bulbs? I see a few different kinds in here...

The indicator and brake lamp bulbs are Ba15S (p21w) bulbs. You can find plenty of aftermarket led versions online and in parts stores.

I would be careful putting in LED lights for the indicators, as the lower resistance can affect the speed of the indicator flasher relay, and cause issues there.

My recommendation would be to use halogens in that case. However, it is possible to retrofit a new relay into the old bosch socket. Some new relays are load sensitive, some aren't, the ones that aren't are capable of running LED or halogen lights at the same flashing speed, so I would retrofit one of those.

Solution!

I'll keep it short and sweet for somebody in the future to follow along to.

Before the fix

Bosch Relay has 3 pins. Bosch relay follows DOT/SAE standard: J590C/J945
(Aus local parts store) Repco has Narva flashers with 3 pins, and the same standard (J590/J945) [No C- dont know what it means haha]
The flasher is 21W x 6 bulbs, w116 has 4, but it works fine regardless.

The Bosch Relay features 3 prongs labelled: 49, 49a and 31.
49: +/ignition
49a: Lamps (the flashing one)
31: -/Ground

The replacement features:
B or X: +/ignition
L: Lamps (flashy)
E: -/Ground

(It can vary so please read the label on the box)

Soldered on terminals

Neatened it up a touch

I then soldered on some cabling, and put some connectors on. And voila, works fantastic.

Finished product

Perhaps if one was so accustomed to a blinker sound, a buzzer could be attached to the flashing line of the relay, but I personally dislike the sound, so I just left it as is, with a quiet tick tick.

Last post by adamb - Yesterday at 03:50 PM

Just checked 07.3-280 regarding replacing the fuel pump. It seems that up till april 1980 the check valve was internally in the pump, and after april 1980 the valve is external. The internal system used a hollow bolt to attach the hose towards the filter onto the pump, while the external version uses a cap nut to attach the hose. See https://handbook.w116.org/Engine/107/M117_45/073-280.pdf

Do you know how your hose from pump to filter is attached (or perhaps share a picture)?

It took me a while to make time to look at this issue but I finally got round to it. Max was right - the problem was due to the replacement pump that didn't come with a check valve. So pressure was dropping because fuel was flowing back through the pump.

After fitting the check valve the pressure stays at >3 bar with engine turned off. I checked all other pressures and they are within the required ranges.

Here are pics of the old and new set-up.

Mechanicals / All brake light bulbs?

Last post by NalgeneSF - Yesterday at 12:18 PM

Want to replace my brake light and turn indicator bulbs with new lights which are preferably LED. Anyone have the part numbers readily available? Or have done this job before. Would also be happy with the right bulbs as it seems like there are 4 or 5 per side and I'm not sure how to match the part numbers online. Bit of a silly question I know, but would be helpful to hear all.

There will be a very clear break in the wire if blown.
