Chen, the short answer is yes in all likelyhood that speedometer can be made to work with the three wire hall effect sensor. Simply put, the hall effect sensor will emit a pulse train on the signal wire which could possible be used by your Autometer speedometer. However there are a couple of critica...

Just drained and flushed the cooling system. The leak sealer certainly did it's job and the weeping from the headgasket has stopped. I had used Wynn's Premium radiator leak stop. I called the Wynn's distributer and asked him about the product. He was admant that it would not create deposits or sludg...

Tim Jeez, that's not bad at all then. My issue is that my motor had been completely overhauled by an Alfa specialist and has no more than 5000 km on it. So I'm a little suprised to have developed a leak so soon. Sam, with respect to re-torqueing do you mean that I should mark them first, untorque th...

Just out of curiosity, how old are your head gaskets?

SamW, too late! Damn. I will drain and flush the system this weekend, hopefully it won't have messed things up to much. With respect to the head bolts, I did check the torque of them and they were well within spec > 80 ft/lbs. I don't wan't to over torque them so I'll go the new head gasket route. I...

Leak Found! Turns out to be a weeping headgasket just below the exaust manifold. I have verified that no water is mixing with oil, and my compression is fine. Since it is not leaking badly I am currently trying the cheap fix with Wynn's Radiator Leak stop. Will let you know how this works out. Marco

MD,

that's exactly the advice I needed!

I'll give that a shot. Thanks so much for the sugestion.

Cheers,

Marco

MD,

thanks for the sugestion. Pressurizing the system will certainly tell me I have a leak, the problem is it won't tell me where the leak is.

I am loosing about 250 ml of coolant a weak through a drip comming somewhere from the right side of the engine. Do the space confines I could not determine where the leak is comming from. I know it is not comming from any of the hose junctions however since those were easily checked. The leak/drip o...

81GTV6RESTO Thermocouple theory states that heating of the thermocouple element causes a voltage gradient between the refrence junction and the measuring junction. The disconnected wires are supposed to measure the voltage across the thermocouple terminals. As the thermocouple gets hotter, the volta...

JimGreek, calibration of the speedometer unit as you described is certainly one way to calibrate the speedometer. Certainly the technique you have described is quite involved. My only other suggestion/ alternative is to simply purchase this wonderful little unit from Dakota digital; the SGI-5. Compl...

Thanks zambon,

Coach, I would recommend either taking the speedometer itself to have tested or trying an alternate unit that you know works. By the process of elimination you can converge on the true problem.

Hi Burger,

thanks for the reply. All the donuts are new, however, I spoke with the previous owner who told me I should probably get the driveshaft balanced.

I honestly can't feel vibration during driving, only during idle when I rev the engine.

I have a relatively subjective question, nontheless I think it is valid for me to ask. This question can also go under Gearbox, Clutch and Driveshat but I'll ask it here any way. I have an 85 Alfa 90 which, the drivetrain from what I understand, is fairly similar or typical to that of the GTV6. My q...

coach123 The Dakota unit has an amplifier built in. It has provisions to accept relatively low level inputs, however I don't know what that low level threshold is. The friendly people at Dakota will have that answer. In answer to your question, YES, the Dakota unit should very well be able to replac...
