I keep one set for the wife's Fit (wrong taper lugs instead of wheel bolts, yeah yeah yeah), but the rest can certainly go away. I am, but I'd have to figure out shipping.

So, I got a new job last week. Its in downtown Atlanta, which is not really conducive to driving a manual semi-sports vehicle like the Audi 90 Quattro, at least fuel wise. So I went to 'resurrect' the Jetta. First order of business, new Harmonic Balancer:  Cool! Engine started up easily with a new battery! Then I noticed some rust...  Uh oh...  Oh poo poo. Its the cancer. CommieGIR fucked around with this message at 03:42 on Aug 22, 2015 |

So, after some Google research, the concensus is the Compressor is either bad or the Compressor RCV is bad. So, either way, the compressor has to come out. Seeing as rebuild parts are cheap, I'm gonna take a crack at rebuilding it.  Compressor.  High and Low lines sealed.  Compressor is out! Lets take it apart!  Valve Cap removed  Reed Valve Plate and Valve Stems removed and bagged  And there it is. The pistons and the Refrigerant Control Valve. My main concern is the scoring on the face of some of the pistons, but I see no damage elsewhere. Moisture issues maybe?

How do the bores check out? Assuming it functions just like any other compressor, they might be wore out. But I don't know that much about it.... Also that's cool you took all that apart.

Sat for 4-5 months, now it doesn't, so it would be odd for the bores to suddenly go bad. I suspect the Refrigerant Control Valve.

Follow up: Ordered the Refrigerant Control Valve and gaskets for an SD7V16 compressor. Rebuilt mine with nothing but photos as a reference, refilled with oil, filled system with R152. HOLY CRAP COLD AC. It works! Now I can run my more fuel efficient vehicle to drive downtown instead of my fuel hungry performance car.

repost from the VW Audi thread: So i got the 15 tdi last weekend and my question is this, it seems that tdi's actually have a pretty serious breakin regime (according to the tdi hive mind forums), is this something i need to be following or is it more of an undying urban legend? I really was enjoying my 47 mpg city, but with this break in driving i am down to a measly 30mpg city.

Just make sure you are following the recommended oil change cycle, other than that, drive it hard and drive it fast. Wearing in the TDI motors involves some good heavy driving.

So call me crazy, but could i just buy some sandbags and throw them in the trunk? That would force me to use more throttle/load and help get a better seat on the rings (but not have to speed as much), or is this a totally stupid idea?

Drive it hard. You will sacrifice fuel economy now, but it'll pay off with better longevity and sustained performance in the long run (performance including fuel economy, worn rings later means you use the same amount of fuel but lose power to blowby).

Lord of Garbagemen posted:its the dsg but i can rev it up high, im just worried about getting popped by the fascist police around here. Technically, running the motor hard IS introducing a heavier load as far as the piston rings are concerned. Adding weight is kind of a way to work around it, but its better to just hard rev the motor and might not really get the seal you desire. Remember: Piston Rings seal due to the gas pressure from the combustion chamber, higher pressures (i.e. sitting in higher revs) will help push the rings into the walls, creating a better seal and, in the long run, better 'seating' for the rings into the wall. You want to italian tune it every now and then...say, when coming off on on ramp or merging. Give it a good thrashing. You want to do this in like Gears 2-4, not 1st.

I read the guide on the forums and he said 75% throttle and i found myself doing like 60 in a 35 pretty often. Ill keep the revs in the designated ranges and just goose the throttle when its appropriate to do so.

I wonder if the need for break-in could be reduced by machining the bore to a sufficiently low roughness.

Enourmo posted:I wonder if the need for break-in could be reduced by machining the bore to a sufficiently low roughness. The idea is you want the differences to hone themselves out to make a more perfect match with the rings, the idea being: No machined part, ring or cylinder, is perfect, so if you can let the ring and the cylinder 'match' themselves through initial wear, you can get a more perfect seal.

List of things the Audi 4k still needs from looking over it today: - Coolant hose from the water manifold to the turbo coolant flange - 2 x battery terminals in the engine bay for the battery move and another distribution block - Power steering pump from a 200/5000 and hits mounting bracket and power steering hoses - 3B intake hoses and intercooler Things that I should do before going road-worthy: - Run new fuel and brake lines CommieGIR fucked around with this message at 22:19 on Sep 26, 2015 |

Started the Audi 90 this morning, only to be greeted by a very chunky sounding lifter rattle. Not like the normal Audi lifter clatter until the oil circulates, but a nasty sounding metal rattle. So she is parked till I can get to the lifters. Not too expensive to fix at $12 a lifter, but not worth risking motor damage to drive.
