Suction Pipe?

[TG-2002-320i-328ci]

With Arizona driving season (non-A/C vehicles) kicking off in the next 4-6 weeks, I finally started the arduous process of replacing my dead starter. To give myself working room on my CSi, I'm removing several hoses and the last three suction pipes. Even with gentle (hand) removal, the cylinder #4 "suction pipe" must have had a hairline crack form over the years, or a previous mechanic may have over-tightened the bolts - because the pipe came off in two pieces.

The pipe is marked 6 Zyl 225 (BMW) 1 256 568. I get zero results searching "1 256 568". RealOEM.com has the part marked on Diagam 11/40 #14 as 1161 1 256 567 (note the "67" as opposed to "68").

I've checked with wallothnesch.com, and they also use the "67" part number and they are out of stock. There are a couple of sellers over in Lithuania and Latvia selling single units - but do I want to trust them (I've travelled in both nations and love them... but...)?

Also, the 1161 1 256 567 part number comes up as a part number for later M30 engines (5/6 series).

Thoughts?

That is the right part, later l-jet cars used the same C runners, best bet is to find a used one. Strange that it fractured.

I've found a new 1161 1 256 567 on bmwpartsdeal.com. Never heard of them until today, but they had one - or, let's hope that is what shows up.

I was surprised by the fracture, given that all three slipped right off (no sticky gaskets). Nothing should surprise me about a 50 year old engine...

Get new gaskets while you are in there.

I ordered those before I dove in. The only issue now is that I will have 5 dull pipes and 1 shiny new one, which then gets me thinking about having the other 5 vapor-blasted. I'm never able to just replace one part on this car...

You could go a littler crazy and get 6 320I (77-79 ) C tubes, they are a bit bigger in diameter

Thanks, Rick

Or, leave the new one out in the weather for a while to dull down to match!!!
If you vapour blast the inlets you will need to do the rocker cover also, then…. And finally paint the engine block
The finished result will look great.

It would seem to me that every guy who went with the 320I tubes has some well-weathered tubes in a box somewhere.

Many causes for aluminum alloy breakage, including poor casting or even rough handling (e.g., dropping). As an alternative, you might consider taking the two pieces to a reputable machine shop or welder. Numerous fixes available.

we regularly those in the trash bin.

I can look today if you want.

By the way - for this starter job I bought S-Wrenches, a used 17mm Snap-On U-Joint Socket, as well as a thin 17mm open wrench that I ground down. None of those would fit or give me the leverage to remove that top 17mm bolt on the starter. However, I could get the box-end of a 17mm wrench on the nut with some room for movement, but the length of the wrench did not provide enough leverage.

Solution: buy a Harbor Freight (great for single-use jobs) 17mm wrench, chop off the open end, then used a metal pipe with an interior diameter close the width of the 17mm wrench handle and voila - leverage. The bolt immediately came loose.
