Two Part Thermostat Housing Question...

[Joe_E]

First part...
Never bought these parts new before so this OEM green thread stuff is kinda new to me. Is this sufficient as a sealer or should I put a couple wraps of the trusty teflon tape on there as well?

Sure is a perty purple taint it?

 

[Spike Strip]

They're tapered threads, so that sealant is fine.... What's the plug for ?

[NLXTACY]

I went with them as is, no teflon.

 

[Spike Strip]

Ah, I found it - That's the plug in the rear of the intake manifold... How come you're replacing ?

And curious, is that plug the same thread as the BVSV's ? Be good to know for a desmog to plug the holes in the lower T-stat housing.

...

Cause thanks to fellow MUD member cahilc I got me one of deez...

 

[Spike Strip]

Wow... Is that new, or painted ?? Either way, sweet...

Also, will that plug fit in the lower T-stat housing ?

Just trying to keep up with the Joneses, or in this case the Spike Strips'!

Yep, she's brand new. He bought it but decided to go to a smoker.

I'll check out the plug size in the water neck and let you know the results. Besides it'll give me an excuse to go back to the basement TEQ rebuilding and parts accurement center.

I've got a bad case of Manifold envy.

Well SpikeStrip, you not only have a keen eye for nice manifolds but for plugs as well.
I tried inserting the valves into the manifold and the plug into the thermostat housing and have come to the conclusion that yes Virginia there is a Santa Clause.
I put the mic on the top threads of the plug and valves as well and both came up 16.58 mm.

So now we know it fits. Next question, would you want a plated steel plug in an area that has contact with water and antifreeze? Or would something made of brass be better suited to avoid corrosion and subsequent saddness and high blood pressure trying to remove a corroded plug?
I'd go with the brass or leave in the valves personally. My BP is high enough already.

 

[Spike Strip]

Oh, yeah, definitely brass -- Thought that plug was brass. But with enough anti-seize or the right anti-corrosion sealant, it'd prolly be ok... But you're right, just the cut-off valve ends would be good, too.

So just by cutting off the pink and purple parts, would make it a plug? What are the purpose of those anyway? (I am in the process of desmog)

One BVSV when it warms up opens to allow vacuum to the EGR modulator.
The other allows vacuum to the main diaphram of the vacuum advance on the distributor when heated up .

if you are gonna go through the trouble of cutting them up you may want to sell them to a smogman if they work and find a brass or stainless plug instead. They are not cheap.

Both plugs broke when we removed the vacuum hoses.

Thanks for the tip!

I used one of the plug holes for a temperature sending unit.
