I'd echo that. If a car one ton car is jacked incorrectly, then roughly one ton of force, judiciously applied, should undo the damage. The tricky bit is clamping it and tightening it up so you can apply the force where it is needed.

Re: oil pressure sender calibration widget
What Chris has done in post #37 is very sensible. The gauge only needs to be roughly right from 10-70 psi as the oil light will tell you if you have dropped below ~3psi (panic!) and the oil relief valve will cap the pressure at about 70psi on cold startups. To be frank, the gauge can't be more accur...

Re: oil pressure sender calibration widget
To test my gauge I put a potentiometer in line replacing the Sensor and I got roughly Pressure Reading 0 = 240 ohms 20 = 225 ohms 40 = 128 ohms 60 = 86 ohms 80 = 50 ohms I hope this helps, and welcome any suggestions if you think I'm on the wrong track This is roughly what you'd expect from the gau...

Re: Oil drain bolt size
It's all one welded assembly. It's not like a single piece s1 or s2 picture frame. The s3 picture frame is a two part assembly. The top bar comes off very easily with just a few bolts, but the bottom three sides are a very heavily braced "U" shape and will need a substantial amount of work to remov...

Re: S3 V12 rebuild engine misfires?
No, "more vacuum" means the engine considers it a lighter, easier load.
If you run at 800rpm and the air pressure in the manifold is 50kPa, and then you make a change and it runs at 800rpm but at 45kPa, then the latter is the better setup, whatever that may be.

Re: water oil emulsion
With that last post, it now just sounds like a bit of neglect and corrosion over time. Unless you can see an obvious squigly black line of a crack somewhere, I'd simply clean things up and refill with water as Bill suggested. The head gaskets were the most likely path since they are steel and coolan...

Re: S3 V12 rebuild engine misfires?
Dear Paul, you don't want to set up the engine to settle at 500rpm. This will present a harder load to the engine and make it more likely to stall when it gets there. The manual probably tells you to aim for ~850 rpm as a default. By comparison, to land at 500rpm, you'd have to choke off the air sup...

Re: water oil emulsion
All of the metal (aluminium) parts are several millimetres thick, so it's quite hard work to corrode your way through. The distributor sits on a level surface and if the car has been left out in the rain, water can accumulate and drain off to the lowest point. The chief suspect would always be a hea...

Re: water oil emulsion
The water pump is bolted onto the front of the timing cover and the timing cover is pretty thick.
If it hasn't come through the head gasket, then what does the distributor look like?
kind regards

From the description, you sound lean and retarded. One or the other, or a bit of both. So the whole A bank has been dismantled....

To find out, put a bag of frozen peas on the OPUS or temporarily patch in a spare unit and attempt a restart and report back.

Re: Rattling good fit !
So either the rubber seals flex slightly differently in the time it takes to release pressure or there's a bit of rust on the piston which deters it from moving back. It all points to a strip down at some point. Why? It's not actually broken in any way and the brakes work.... If you find nothing whe...

Re: One rear amber flasher not working.
I don't think I can help given the vague replies given. Get yourself a wiring diagram and refer the faults and responses to the wiring diagram rather than using terms like "amber feed wire". We still don't even know whether you have a problem on the left or right of the car. Given that this is proba...

Re: One rear amber flasher not working.
So is this the s3 car you were asking about in another thread? If so, the s3 has all of the indicators in parallel. That's the two indicators per side, the green tell-tales in the dash and any additional side repeaters. If it only happens to one item, it follows that you must have a wiring problem. ...

Re: Bad oil leak - possibly from Oil Sender/Warning Light Switch(es)?
That's a good result. Near zero maintenance work and near zero cost. With luck, the new oil switch will be good for another 40 years, so there is no pressing hurry to replace anything. Later cars had a blank plate where your senders are. Instead, the oil line leading up the the cams joined onto a li...

If the pipe is blocked, it'll be blocked where the tubing is at its thinnest point, not at the single broader tube. That means you'll have use some engine degreaser to dissolve out any solidified residue in the thin 1 to 4 tubing and then blow that out before refitting it. You never mentioned what y...

Re: Bad oil leak - possibly from Oil Sender/Warning Light Switch(es)?
That sounds very sensible. There must be a reason why they moved the senders from under the exhaust manifold to up top. They obviously get toasted down there.
