Ill feeling 164E

Yes, I fitted new ignition components thinking it might be the worn out points. They were quite pitted when I changed them. I set the timing with a strobe to 10 degrees BTDC as per my manual. I don't have a dwell meter so I have to set the points by gap size. I set it to 0.012 inches. Manuals states a minimum gap of 0.01 inches.

I'll try blocking the tube to the aux air valve and post my findings. I keep the oil reservoir on the distributor topped up. I'm not sure if that oils the felt for the timing advance though.

The kettle is always on if anyone wants to cross the pond!

The tacho does drop to zero even when the car stalls while I'm driving. I didn't know that D-jet had a fuel pressure sensor. Where would that be?

My mistake, not fuel pressure sensor, but fuel pressure regulator!

These are factory set (to 2.2bar I think) on the B30 engine, and are simple sealed units with an internal diaphragm.

If they do go wobbly the only cure is a new regulator.

The D-Jet system does rely on that regulated pressure, so I wonder if it's worth checking out your fuel pump and filter etc?

Thinking it through though, my gut feel is that this is more likely to be electrics rather than fuel delivery.

PS: Thanks for the invite - we'll all be over (complete with wives, kids, dogs and in-laws) a week on Thursday if that's OK!

[Lesky]

Thursday is perfect! Haha.

So here is what I've discovered so far. I ran it till the engine warmed and my aux air regulator is stuck open. When I cover it the tube, the idle speed drops down pretty noticeably. Is there a way to lubricate this and possibly work it free? Fuel pressure is good without any signs of a wobbly fuel pressure regulator. Also, I have a vacuum leak on the brake booster. Are there seals available for the vacuum line going to the brake booster?

Here is where air is leaking in on the brake booster. It's leaking in between the 90 degree elbow and the booster itself.


Also, does anyone know what this little guy is? (the sensor sticking in the vacuum line below the idle adjust knob) Can't find anything on it in my green manual.

If its the knob with red arrow , I think you will find that you can alter the tickover it did on my 164E

Yes, you can have a go at releasing the air slide.

The attached note from Amazon cars in the UK might be helpful.

Failing that, you could fashion some sort of manual device controlled from the cabin to close off the aux air device.

I've been told it's possible to modify the aux air valve froma 240, but I've no details on that.

I guess for the leaky brake booster it's going to be a matter of trying to source whatever actually creates the seal - an O ring etc. You could try sealing around the outside of the elbow/booster joint with Dum Dum putty. It's pretty amazing stuff!

Don't recognise that sensor at all! Maybe it's something to do with US-spec emmissions control regulations?

By the way, our flight gets in at 3 am Sunday morning - can you meet all 15 of us at the airport?

That solenoid thing above is an idle speed compensation air bleed , when the Air Conditioning pump is on the valve lets more air through to compensate for the extra load and therefore the idle speed stays the same or rises slightly ..

Ah.....so that's it!

For those of us of the Saga generation aircon in a 70's car meant opening a window.....we weren't treated to such luxuries when I were a lad!

yes Volvo had AC in the 70's the 164 TE had it as standard but 140 had it as special factory order . about £1200 if i remember correctly . Both had huge YORK twin cylinder pumps bolted to the engine ...
