[Jake Raby]

I can't believe that you still have people that haven't paid! Actually, I can because I know how group buys go and I commend you for putting this together and dealing with it.

If someone ends up not paying I'll buy two to help the group out.. I have plenty of applications for them. :-0

Still waiting on 2 payments as of today,

I'm really surprised you didn't receive mine in the mail by Friday.
I paid extra for the peace of mind that it would be delivered on time.

We Have Sensors !!

Now I need to check the status of our gauges (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/beer3.gif)

Can you post detailed pics of the ring and sensor? I tried to fit one of these recently and found that the Sensor was to close to the ring to fit under the spark plug correctly on my 1.7 heads. The tab needs to be able to bend upward without separating or compressing where the sensor is attached to the ring.

[jsayre914]

I would hope that is not a problem, but a great point. I will try to test out on my engine tonight, but I just finished dressing the motor and I do not want to dissasemble the tin at this point. I am not sure if these pics will help but herya go

(IMG:style_emoticons/default/beerchug.gif)

Worst case: They dont work, the gauges never show up and I refund all the money (IMG:style_emoticons/default/blink.gif)

I think we are good (IMG:style_emoticons/default/smile.gif)

p.s. Anybody have a head layin around, or a pic of one of these installed??

[Jake Raby]

These are the exact same sensors that I use with my data logger on TIV engines. They are a tight fit on a bone stock head, but they will work. In a perfect world a small passage is filed in the head that allows the sensor to be fitted at a reduced angle. This is not required in my experience.

[mrbubblehead]

would it help to remove the crush ring from the spark plug?

[ChrisFoley]

Here's what I've done on 1.7/1.8L heads.

I modified an old spark plug to fill the hole while I use a carbide burr to make a relief cut in the head.


Bend the sensor carefully to sit/stay in the pocket.


Much better to install the sensors under the tin rather than through the spark plug hole.

I thought this might have to happen. Removing tin is going to be the way to go then (IMG:style_emoticons/default/blink.gif)

[falconfp2001]

Just purchased online the panel for mounting the gauge. Hopefully everything is timely.

which one did you get?

I have my #3 single CHT installed through the tin and it's a pain in the balls every time I need to change that spark plug...the thought of doing it to all 4 makes me sad.

Chris
Would the procedure be pretty much the same for a 2.0L head? Also, any issues with the ring coming unseated when you change spark plugs?

[ww914]

I don't have my engine here at this time to speak very clear about my idea, but here it is. I was thinking of making a hole, big enough to put the sensor through the tin, someplace near the spark plug hole, so I can see all the action when I am installing the spark plug/sensor. Of course, there would be an appropriate size grommet in the new hole.

And, thanks to Chris for posting the pictures of the need to modify the spark plug hole to make the sensor fit relatively flat.

One other question. I assume the sensor goes against the head, then the washer, then the plug?

[rnellums]

So it looks like to really do the install properly, we should remove the tin and perhaps grind the head just a tad for the lead?

[rwilner]

Of course, there would be an appropriate size grommet in the new hole.

You'll need some type of grommet that covers and seals the hole.

The seal between the spark plug wire "skirt" and the tin is important so that the cooling air flows over the head and doesn't dump out uselessly into the engine bay.

[mrbubblehead]

on my last engine, i used the stock cht hole, but i was only reading one cylinder. and i used a quick disconnect and just unpluged it for engine removals. but this time since i will be reading all four, i am going to notch the cyilinder head, so the ring terminal sits flat under the spark plug and maybe put a dab of jbweld to hold the wire in place. then notch the tin near each side of th intake manifold. and since cold junction is not a problem with this instrument, i will probly use the disconnects again. they work good for engine removal and ring terminal replace ment, i figure the less i disturb the ring term the less it is prone to damage.
