Yes, Steve R is helping from the sidelines. It was an OPC full rebuild and he supplies them so is cautious with attribution of 'blame' but is helping on the technical aspects. It was him that told me it's only truly fixable with a reseal.

My friend Peter Booth at https://www.motorscience.co.nz can help you invert your Photo and your car.

Haha, it looked fine on my iPad Safari browser. Just looked at it on my pc and can see what the comments were about. I suspect it's based on my being left handed and the consequent iPhone orientation. Evidently only iOs is able to compensate.

Benny Hill used to have a segment on his show from the U.K. that went "and now from Austraila)
and they would invert the camera.

The first page of this thread specifies Dow 111 for O rings. Is Dow 55 a general substitute for Dow 111 or is Dow 55 specific to this application?

I can't speak intelligently about Dow 111 because we don't use it.
We chose Dow 55 because of it's military application (testing and continued use). We buy it as military surplus because when we started using it, Dow 55 was not available in retail packaging.

Thanks Henry.

I think I missed it, but does anyone know how fast 1184 cures?

I am wondering if I should apply the 574 on saddles first or the 1184 on the perimeter first?

TIA,

Jim

I think I did 574 first. The 1184 skims over pretty fast.

The 574 is an anaerobic sealant (dries in the absence of air/O2) so apply it first. It won't start to harden until you clamp the case halves together.

Thank you sirs :-)

BTW, how does one keep the 1184 from squeezing into the case? I did a couple of test runs and boy the 1184 really squeezes out allot.

I am not wrried about the 574 but do worry about silicon getting inside the case.

Noticed the case thru holes only have chamfers on nut side

No wonder the old orings were crushed and ripped on one side

Should I chamfer the Bolt side?

Check the washers, as I remember half of them should have a chamfer and those go on the side of the case without a chamfer and the others should be flat?

Chamfer the holes. Use chamfered washers. Orings will be happy

Thank you Brothers

Yes all the washers are chamfered type

Will be chamfering/deburring the d-side case thru holes

You just need a very thin coat but you want some squeeze out. The 1184 is not silicone RTV and it is semi-hardening and remains elastic so it doesn't break off like the silicone RTV does. It's the same stuff used to seal motorcycle cases, also sold as Hondabond 4, Yamabond, Suzukibond 4, etc. it's good stuff.

Good Stuff, Nice :-), better use the acid brush, painter putty knife leaves too thick of a coat.

One more, is it okay to have the 574 and 1184 contact each other, like bottom of the #1 and top of #7 bearing areas?

TIA,

Jim

That won't hurt anything.

Throttle Body to Intake, SEALANT or DRY?
 

Hey Fellas,

Besides using the new back O-ring in the Wrigtwood Kit, I assume no sealant but just want to make sure. Does anyone happen to know the torque specs for the four allen bolts

TIA,

Jim

Answered my own question:

No sealant just new O-ring :D

Torque Specs, anyone anyone?
