There is more to the crankcase breather system then that. See this thread:Breather Thread

Thanks Shane, I shoulda been following that thread.



I saw the two hoses from the right cam cover, but they both go to the filler tower, correct? Or is there a T someplace? The TB was filthy, so I couldn't see if one went to the TB-elbow.

Oh, it is quite fancy, isn't it - after a liberal dose of brake cleaner and using a fiber optic flashlight I took another peak down there.

The rear cam cover hose goes to the U, the front to the fill tower, and lastly a hose from the fill tower to the front of the U. BTW: there's nothing in PET, nor the WSM which show the 85-86 breather hoses, that I could find?

The hoses to the TB have got to go!

Nice stable PorKen. Looks like you'll be busy this winter.

Exactly why I made them disappear. It is no wonder there is always some oil in the '85-86.5 intakes.

Tim,

The neighbors probably think we deal drugs or something, with the hardware we've got parked out front. Everyone else on our block have 'regular' cars.
...

Now after driving around town, and getting a few miles on it, the driveline is starting to get better. The transmission is shifting properly, albeit with no kickdown, as the cable to the trans is buggered. The whine which I thought might be TT bearings seems to have gone away after filling up the transmission to the proper level! The engine is perkier, but it's not as peppy as the '81, yet. The car just feels massive compared to the '81, except when I hit the brakes, then it feels like a Lotus.

On the flip side, things are starting to konk out. The odometer stopped. The A/C blows hot. Dash lights are out. An oil leak off of the passenger cam cover makes a big cloud of smoke at every stoplight.

I unplugged the key-in-ignition switch under the pod to stop the chime - I'd forgotten how annoying that is.

Nice... Sounds like you really made out on the car. Once you get it ship-shape, it will be quite the cruiser.

Dave,

Yeah, it's cool. Well, mechanically speaking. The paint is OK from afar, but the body is full of bondo - old timer at the Mercedes shop I get parts at said: 'that car's been to the fair'.

I'm over the purchase high, but now I realize that it's going to need a lot of parts just to safely drive. It's cool that nothing has been changed on the engine since the factory, then again, nothing has been changed since the factory!



It's nice to have two, ya know... I don't have to drive boring when I've got one down for service.

"All Original"

Still, as much DIY as you do, sounds like the generally-advised $2-3K will get you a damn nice cruiser... barring major trans issues. That noise is most likely TT/TC bearings. Great car for $6500. Don't worry about the bondo, it helps traction.

I finally got her all tuned up, and today put I put in Rotella 5-40 synthetic. I didn't drive it, as I was forcing myself to wait for a working PorKensioner, before changing the belt.

All I can say is - it was worth the wait!

On the way home tonight, returning from MalWart with another gallon of Rotella (forgot that two gals is just shy), a brap-brap-honda starts speeding past me, slows then speeds past. We happened to get off at the same exit, where I knew there was a two-into-one lane right after the offramp light. I put it in [2], and as I turned wide into the outside lane, put it to the floor. The Honda was literally frozen in place as I wooshed by, with that sweet turbine sound of the 32V. Then it hit second and the tail went side to side. (Jepers, it really has to rev up there to get into second gear when you have [2] selected!)

And this is stock, but for an RMB + air pump delete (and a PorKensioner)! I replaced the Temp I and II sensors, spark plugs wires, plugs, distributor cap/rotor, almost all of the intake boots. I replaced the idle control valve, which is cool now that it works. I think the MAF may have been rebuilt. It has a slightly messy bead of clear silicon around the cover, and AFAIK works fine. I attached the overflow hose on the trans reservoir, which was previously dumping oil everywhere after sitting.

I replaced a bunch of fuses, fixed some vacuum leaks, now the A/C works fine. I took out the ratty placemats, and the carpet looks OK. Still the hatch release doesn't, the horn blows - a fuse, the windshield is cracked, sunroof is kaput and leaks, bondo... but man is this a sweet car for ~4 grand total so far. Especially from a few feet away.



I had a local muffler shop make the RMB, after I showed them that the ball joint only need a simple flare to connect it. It's really not loud at all on the stock true-dual exhaust system on the 86.5. It doesn't have mandrel bends, but anything is going to flow better than the 20lb pumpkin!



Shane was right when he said that "the 86.5 is the GTS of the OBs".

I'm reminded of that recent credit card commercial. "Vely, vely, vely revardink"

I have the same interior and piping except for my carpets are black. White, red, and black is exotic and manly .

You really made out on that "test mule", Ken!

The piping was red originally, but has faded or has had the color removed somehow. I would like to vinyl paint the piping black, sometime.

I unplugged the horns, and plugged them back in, and now they toot! One of the horns had the connections reversed, but I shouldn't think that would matter. I plugged them both in the same way, and they work, but it probably just needed the terminals to be reseated.

The ABS is pretty neat. I tried it out on this tree covered back road, with thick piles of wet, squishy leaves, downhill, off-camber at about 10mph. Under full braking, the car shifted side to side slightly as the braking shifted wheel to wheel, but it did stop straight in a fairly short distance.

With the 2.20 rear end, even with the low 2700rpm torque peak, it's not quite quick enough for my taste, around town. I'm going to bump up the cam advance by 2░ cam, and see how she does.

PorKen,

Sounds your 928 isn't unlike most that haven't been babied by guys like us on the list. When you first get most 928s from regular joe's there are many little 'gotta-fix-its.' They get that way by sitting and through neglect.

I took my P-cars for a spin this morning on the curvies and found that the 968 needed a new DME relay in this colder weather. I had a spare and it starts easy again. My 928 can sit 2-4 weeks and immediately start up. I don't let that happen often but when the snow/salt hits, it stays in the garage.

Wonderful cars...and once you "learn them" the 2nd car is pretty easy to diagnose and fix....relatively speaking I guess. I'm still learning.

Good motoring...I love that white paint you have.

Harvey
