350SE/SEL/SL/SLC Engine Parts Pic HELP Please !
Hello ;
I need an exploded picture (parts book ?) for an early W-116 or 107 with the 116/107 V-8 engine , the alloy bracket that holds the A/C compressor to the engine block is wobbling about and leaking oil so I'd like to see what I'm getting into before I rip my daily driver apart . Anyone got a parts book they can scan ? or links to parts diagrams please ? THANX ! .

O.K. , thanx ~ the Russian source is missing that part of Group .013 that details the A/C compressor mounting .
I looked in the 107 , 116 and ALL the pages , it's nice but missing the info I need . -Nate Quote:

Did you look here? This is pretty detailed.
http://handbook.w116.org/Climate/83-522.pdf If you are leaking oil in that area it is probably the chain tensioner.

O.K. , I'm printing that out , thanx .
Interestingly , it shows York and Delco typ copressors , my car is a European model so maybe that's why it has an alloy compressor that looks different . Tensioner leaks eh ? uh - oh ~ I don't hear any timing chain noise , cold or hot . do they whip & slap when they get old and wear holes in the timing cover ? .

Thanx , I know about the timing chains breaking and ruining the engine but I'd not heard they can wear hole in the timing cover .
The chain is dead silent anyway , I was under the impression that the 116 engine didn't have these issues...

I believe the notorious chain snapper was the 380 V-8 circa 1980/81, single rowed version that should be avoided. Otherwise timing chains and tensioners on all MB's should be replaced each 150k, 200k miles at the latest. And anybody who doesnt replace the TC, tensioner and top rails on older engines is crazy cheap. New timing chain provides immense engine performance improvement. And the 4.5 116 can easily run 400k miles if well maintained.

The tensioners from this vintage have an o-ring seal, that, at least on the M130's dries out and leaks. I had a massive leak from that exact area on a 250C that was misdiagnosed as a front crank seal seal.
Also, it is possible for the bolts/studs that hold the compressor bracket to the head to leak past the threads. There is not much metal between the end of the bolt/stud and the oil galley. If that metal breaks or cracks, then the threads offer little resistance to oil leaking out.

THANK YOU CHUCK !
It appears you have provided my answer at long last as I was trying to figure out how the heck it could be leaking oil past the bolt threads . Do you know if this Euro spec. car came new with the alloy compressor & mounting bracket ? . I've been looking at all the V-8 Mercedes I can find in the junkyards , all of them have plate steel mounting brackets and Delco compressors , evern the '88 500SEC I looked at  I'm stumped now . Can you give me a link tp pix or info on this O-ring ? I have a leak in the left front engine area behind the compressor , it looks to be leaking past the bolts but might be the O-ring...

I think the plug for the tensioner is 26, and the o-ring is 29 in this picture:

Posting Pix
I can try ~ 1st. I have to get a picture then I can post it...
#1 son was looking at the sub frame bushing job to-day and may be going to attack it soon , I'll ask him if he can take some pix of it whilst the sub frame is down , you know it's really tight in there so legible pix may be a wish . I was looking at some loose AC compressors in the junkyard yesteryday , I found one I thought looked the same (?) and turned it over , said " Nissan " on it FWTW... -Nate Quote:

Tensioner Pic
That link comes back as broken or no good...
It may well be aftermarket AC as this car had NO options when new ~ zip . No sunroof , manual windows , no cruise control etc. the AC temp knob isn't a Mercedes knob either ~ I has thought it was a replacement knob but maybe not... Thread sealant ? like IndianHead Shellac ? or more like blue RTV in a tube typ stuff ? . -Nate Quote:

Got It !
O.K. , now the link worked ~ THANK YOU ! .
The oil leaking is from the left front , below the cylinder head , that plug looks like it screws into the head so maybe it is those doggone bracket bolts , I cannot see all of them anyway , will have to try again soon as I need the car ready for the 2007 No Frills Iron Bottom Motoring Tour in April.... THANX fellas ! . -Nate Quote:
