M116 and M117 injectors
My 1972 350SL 4.5L has blue injectors.
Manual says these could be: 0 280 150 015 - Injection valves without protective sleeve 0 280 150 024 - Injection valves with protective sleeve 0 280 150 036 - Injection valves with protective sleeve & double sealing ring Protective sleeve is 000 987 19 45 (Don't know if I have these or not) Injectors for M116 engine appear to have similar specs (380cc/min 37.3 lb/min, 76HP, Tested at 300 Kpa), but they are color coded Yellow. Ending numbers are 013, 022 & 034. Sleeve is 000 987 18 45. Finally to my question :- Is it possible to use the M116 injectors in an M117 engine? If so, which protective sleeve would I use? I would like to buy a set of injectors as spares and there is a set of yellows available. Anyone know what the difference IS between the yellow and blue?

This shows that the M116 injectors have lower capacity than the M117. The other site I found showed them being the same! This one say yellow M116 injectors have 254.1 g/min capacity and Blue M117 are 364.3 g/min. A bit surprising since HP of two engines is about same?

the M117 4.5 engine has a huge WOT enrichment.
that´s why you need those high flowing injectors.

0 280 150 036 are the ones in the 4.5. 024 will work as well.

Yes, that is what the manual says. It's just that someone was selling a set of unused yellow ones (034) on eBay for $80.00 and I was hoping they would work. Anyway, have abandoned that idea!

My '72 350sl (3.5 euro) has yellow injectors that I believe are original. It only has 101,000 miles on it and it doesn't look like they have been disturbed before.

[QUOTE=Graham;1902996]You could have bought the 8 on eBay for $80.00 - saved you all that cleaning
I just sold a set on the rail for $30.

If that was the case, it certainly was misleading. It said "Auction is for all 8 injectors,happy bidding." And starting bid was $80.00. But he pulled the auction anyway.

[QUOTE=Graham;1903131]Yep two of them had cracks where the connectors were. The rest just looked dirty. The auction ended with no bids but the item has been sold to a shop member.
