Cool, yeah if you have wiring experience then it is fairly straightforward.

When I say I soldered the terminals, I meant that I took the connectors apart and pried the crimped terminals off...

[bmwman91]

Yup, all the plastic stuff goes away and you also have to make some new VC fasteners to replace the 2 shorter inner ones. Harvest the rubber grommets from them. Then use some M6 threaded rod, washers...

The wire is grey with a black stripe, and both connector bodies are black. It sounds like you found the one we are talking about. It is the only connector up there....

[bmwman91]

It sounds like a gunked-up idle control valve. As the engine warms up, the oil residue softens and allows the idle control valve vane to more more freely. The ICV is buried on the back of the engine against...

Ha, yet another victim of the LLCO wire connection. "Hmm, this thing is unplugged, I must have overlooked this....."

[bmwman91]

I have not had the front clamp (bracket OP is looking for) on the car for 15+ years and never had an issue. Granted I am running an aftermarket cat which weighs like 60% less than the stock one, but I...

Some (not all) Motronic 1.7 variants used in our cars have ignition coil fault detection circuitry. Only later versions seem to have it. Basically, when the ECU wants to charge...

Ha, yeah I need to just go get on it already. There are a few shops in the area with dynos.

I went and put some gas in it this evening, and then proceeded to "enjoy" it around town...

[bmwman91]

I am glad people found the thread interesting. For now I have no immediate dyno plans, but I will see about getting some runs in at some point....

[bmwman91]

Yeah, it was interesting to see the guts of it. It is so dead simple. The motor is pretty weak, so it would not take too much oily goo to get it stuck in place....

[bmwman91]

The things welded onto the intake manifold are Metric Mechanic's "pulse chamber" modification. They claim improvements to mid-range torque via resonance tuning, but I have no idea what actual...

[bmwman91]

Does it feel particularly weak when trying to get going from a stop? If you give it a large throttle input, either in neutral or when releasing the clutch, does it seem to lose power?

It...

[bmwman91]

Hmm, well it has been so many years since I drove a stock M42 that it is a little hard to say how abnormal the response to the throttle blips is or is not. Those stock flywheels are heavy as shit. Assuming...

[bmwman91]

It does not look terrible. But, it is either some old/original design, or the rubber seats disintegrated over time. If you look at pictures of a new one, you'll see the difference. I am not sure how important...

[bmwman91]

Brake cleaner is probably fine. I think it is mostly acetone.

Well, vac leaks really only affect stuff around idle, so if you are feeling hesitation above 2000RPM then it is probably something...

[bmwman91]

A fairly common cause is a sticky ICV. Did you clean yours out with some carb cleaner?

Can you describe the "hesitation" behavior a little more? Does the engine lose power as you...

[bmwman91]

I have found that very often the oil leaks on the M42 are from the round outlet from the oil filter housing. It is relatively high up and mostly obscured from view, and can run oil all over the engine....

[bmwman91]

OK, as promised it is time for the photo dump of app the stuff I have done since the last set of photos.

The rear shift carrier mount was in bad shape, and sort of expensive to replace, so...

[bmwman91]

Given that you live in Canada and use socialism units instead of FREEDOM UNITS like us Americans, some 15mm (19/32) and 8mm (5/16) hose will be fine. That stuff seems to be fairly readily available all...

[bmwman91]

I don't unfortunately. However, user roguetoaster still has one or two for sale at a very reasonable price I think....
