Oil line fittings - OM606
Oil line fittings - OM606
Anyone know right off the top of their head the specs on the following fittings...
Solved the oil cooler line issue.
Went to the local NAPA location and they had an entire ROOM full of hydraulic fittings, hose and various bits of machinery to make it happen.
This isn't the most graceful solution, but it should work out OK. The fitting is 5/8" JIC which is the same thing as -10AN. Either of these fittings is VERY common here in the USA. I'm still not sure what the exact specifications are on the metric fitting that I cut off...oh well.
Total cost to put JIC fittings on the hoses: $22 and change.
Sweet. I will be using -10An on my new cooler lines, and will have to make up a line fo turbo feed as well, -6 or -4 not sure yet
Go with -4 max. I noticed a slight drop in oil pressure from stock line to -4 at idle. -6 would be too much!
Nice line, Holeshot!
Yeah but what would the line size to the turbo matter? There should be a restrictor at the turbo oil feed inlet... I think honestly a -3an line would work fine. I am pretty sure the stock line size is roughly 3/8" which is -6AN.
I'm going to have to see if the napa up here does that too. Would save me a lot of driving and hassle.
If I remake my turbo feed line, I'm going with -3.
Yea I dunno why ppl go with a big ass feed line if it just gets restricted down anyway...

What turbo are you using?

Seems odd, I've removed that fitting about 5 times and it's never been a problem. I just use a flare nut wrench and crack it loose. As I remember, it's kind of like a brake line fitting inside.
Now, the first time I removed it, I believe I removed the fitting from the turbo first then I went after the block fitting. The whole thing moved at first then broke free after it moved a little.
One option might be to simply cut the feed line and install an adapter to a compression fitting around the line. That way, you could put it back if needed with a fitting inline where you made the cut.
I'm still searching for the proper specs on the turbo oil feed line for the OM606.962.
I went to a few different hydraulic fitting/hose supply houses in the greater Madison/Milwaukee area and they all looked at me and said "Good luck with that!"
If anyone has any idea what type of fitting the turbo oil feed line is (on the engine block side) and some sizing details, that would be VERY much appreciated.
On the original turbo oil feed line, the tubing is thick wall and the flare is non-standard in that the angle is different.
Many thanks in advance!

The OEM turbo oil feed line (10mm O.D.) uses an M16x1.5 ISO/bubble flare fitting where it goes into the OM606.962 (turbo only) block.
So I need an adapter/nipple that goes from M16x1.5 ISO/bubble male convex to -4AN male.
I'm having very little luck finding an M16x1.5 ISO/bubble convex male fitting...and even less luck finding something in that size that converts to AN. Most of the adapters are for brake lines...and they don't use 10mm O.D. lines for brakes. Grrrr....
The search continues...
Here is the original fitting that goes into the block:
...and I TIG welded this contraption. All would be just fine if I didn't nick the tube while welding it. I put just a little too much heat and the tube melted right at the bubble flare end. $50+ for a whole new line from Mercedes only to ruin it. Damn! I should have brazed the tube to the fitting and then TIG welded the -4AN fitting on. Live and learn...

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
That blows. Can you use a M16x1.5 with a crush washer to go into the block? Or a banjo fitting and M16x1.5 with crush washer?
I have killing fittings. Shit like that adds way too much time.

I was going to go the banjo bolt route, but the block is rusty near the boss where this fitting goes and that would not allow for a smooth surface for the crush washer to seal against.
With the block in the car, there isn't much room to get in there to machine a flat surface. I'm not saying it couldn't be done, but I didn't want to attempt it.
I ended up welding the tube from the original fitting to a common male NPT to 4AN elbow (I hacked off the NPT end...). This setup relies on the original flared tubing to make the seal...which is the way to go, IMHO, if you have that option available to you.
No leaks so far, but I still want to find a good commercially available solution - even if it just sits in the glovebox.

Big exhaust leak, no oil leak!
