Tick, tick fixed tnx to Donnie!
Developed a ticking noise about a month ago and also noticed that my oil pressure had dropped abit. But the lowered oil pressure did not alert me to anything that would associate with the ticking noise. It should have but tnx to Donnie, it's now fixed!
Donnie has alerted me and others about the infamous oil tubes used in the 119 engine. Also on the CD-ROM, there's a MB TSB (issued in '95) about these oil tubes. What goes wrong?? Check this picture of an oil tube removed from my engine this morning. Actually there were two with the ends blown out!! One on cyclinder #2 and the other on #3. How about that!!  The oil pressure is back to normal (stays around '2' bar) at idle and NO MORE TICK! Tnx DONNIE! Last edited by JimF; 05-18-2002 at 11:49 AM.

OK, I am going to go and get a eye check-up now as I can't see *****. Are there many special tools needed to do this R/R, looks like you might only need the tubes and a set of valve cover gaskets?
Thanks Donnie.

No more tick!
Roas: Stevebfl's latest pic shows them clearly; It's #65 in the first picture.
400E: On the ALL-DATA CD, the TSB is located after clicking 'ENGINE'. A sub menu called 'TSB' come ups. There's three (3) items on my CD. If you want to see what it says, click below ('WWW' house) to go to my web page, then select Menu #18. Stevebfl: Tnx for the clarification.

R & R oil tubes
Roas, I'm sure you figured it out already but if not here's how to remove them using Steve's annotated figure.
 To change a pair of oil tubes (in blue), loosen and remove the camshaft brackets so as to slip the 'tits' (red arrows) on the oil tubes under the camshaft brackets. Do ONE-PAIR-AT-A-TIME since the camshafts are under tension. Then replace the bracket and tighten before moving on to the next pair. That's the way I did it. Parts: 1) Buy a valve cover kit because you will want to change the gasket and the spark plug seals. 2) Will probably need a 'breather' tube assy. Mine was like the petrified forest!! 3) Will probably need the chain tensioner clamp. If it is as brittle as mine was, it will break when trying to remove it. That should do it.

The "ticking" we are talking about, is it a loud, medium, or quiet sound at cold start-up?
I'm wondering if this is one of those maintenance items that should be added to the "Must Do", "Should Eventually Do", or "Don't do until it Happens" list.

Not sure that you would want to do this as a scheduled maintenance item.
Having gone through this, I now know what to do if the oil pressure drops/changes suddenly! Didn't have a clue before but now it would signal removal of the valve cover(s) to immediately fix. But the bad part is, that you may not get a tick-tick sound right after the oil pressure changes. Thinking back, the oil pressure changed, then about 2 - 3 weeks later, the ticking started. If you don't wait, you would have to pull both valve covers in the worst case to find the 'culprit'. It only takes ONE open oil tube to drop the oil pressure but without the tick-tick, it's a crap shoot as to which side it's on. Re 'SOUND': Mine was a nice clean tick, with a 'clean' note. Not a 'smashing' sound but a more clean tick! Anyone can hear it from the outside although it's almost impossilbe to hear in the car with the windows up. Hope that answers your question.

Are the new parts updated/different part number?
Thanks for sharing. What kind of oil do you run, Jim? Are you the original owner? Awesome harness, BTW-my car's not been over 100, and I beat it BAD on the track

The oil tube part number is the same as it is in the photo: 119 180 03 66. That's the PN that was in my car although the TSB says its 119 180 02 66.
Some discussion: Why the hell isn't that part just a single molded tube. What's with the plug in the end??? As a design engineer for 41 years, that design is just waiting to fail!!! Putting in an end cap that can blow out! Since Mercedes issued a TSB in 1995, that means that this part is (and has been) a problem! So why haven't MB improved it?? Enough of that soapbox. Bought the car three (3) years ago, and have had no major problems with it. I use 20-50 Valvoline every 3K miles. Last edited by JimF; 06-08-2002 at 03:24 PM.

Yes Jim and Steve, thanks for sharing!
There are many V8 M119.974 500E/E500, 400E (M119.975), S-Class, and SL-Class owners out there that are very fond of our little machines, every little shred of information like the kind you have provided ensures that these engines will be around a long, long time. Regarding my maintenance question earlier, I was unsure if this is something that does happen to this engine eventually, given enough time. This is the first mention of Oil Tubes here that I can recall, so I am trying to get all the details straight. Thanks Again.
