Anyone have any experience with these? They seem to be a good idea on paper?

Just stick with what works, I never used the O ring type but had bad luck with the chrome ones leaking.

Agreed, the chrome suck... One would think the heavy billet though would be the schnizzle

The chrome one on my vert was a piece of crap. It had casting flaws that prevented the gasket from sealing properly. Got a stock style Duralast replacement from Auto Zone and it seals good with no leaks.

I think they're a little easier to get off

I have a cvr one that I have not yet installed. The way they do the seal, it’s one oring for the bypass hose and the main outlet, so it’s a royal pain in the ass to get it to hold while you install it. There’s another brand that does the seal with a dual oring, that appears to be much easier.

From what I understand they’ll both tend to leak, which means you’ll still end up using rtv to seal it, defeating the purpose of the oring in the first place.

Long story short, they’re not worth the hassle.

Not exactly apples to apples, but of all the products that I’ve made, the ones that we tend to have the most issues with are o-ring face seal products. So many issues getting those to seal because of the mating interface (which we don’t control). It’s the bane of my existence explaining to customers that it’s not going to seal against the moon crater surface they are installing it on.

Long story short, unless the intake manifold flange is a pristine, freshly machined surface with no defects/scratches, I would stay away from o-ring seal.

I too have had trouble with the chrome ones with the o ring
Last one I had on a car the o ring leaked so I sealed it with a gasket
About a week later the housing got a pinhole and started leaking again
Tossed it

I grew up in the " Cal Custom" JUNK chrome era..... I really question anything chrome.
The heavy Billet Aluminum housings are the ones that I am asking about..
5L5 answered the question the best on here with an Oring being a POOR seal for a pitted area....
I have a BMW and it is full of oringed type seals..... Even the hoses work on an Oring type seal....
When they work they are great, when they don't, they don't...LOL

First, get out of the 'Mr Gasket dark ages'. You pay twice or more for a pos that you can get from the local parts store or even make yourself.
and as for that BMW, a lot of the new stuff built today has a slot type mating surface that uses a rubber rope looking gasket because the surface tolerances are much tighter, flatter and just better maternal or they use a silicone type stuff in a tube to seal, I think most, if not all cars built today don't even use flat gaskets anymore.

Just don’t buy the oring seal thermostat housing where the outlet swivels. Those ones never seal properly as there will always be a small gap between the surface that swivels, and the rest of the housing. That’s really the style I was referring to when I stated they don’t seal for .

Mr. Gasket is owned by the same corp that bought out Holley and more. Who knows who’s part has been packaged for retail display. They are not the absolute junk they were, but when the Mr.G packaging has more cardboard than the gasket, Felpro is the best bet, and Victor Reinz is cheaper and is still a better part that the shrink wrapped stuff.

As a younger man it seemed that T stat leaks were fairly common... I have been out of building engines for years.... If you look at this particular gasket, it is really unique..... Anyone had any experience with it?

What engine and year?
And the non hardening form a gasket/aviation sealer #2 will cover many surface imperfections.

If you don’t know what vehicle you are working on, I sure don’t either.

This gasket looks slick. Unless you are planning on taking it apart frequently, it’s serious overkill.

I read you sold a Dodge, but we don’t know what cars Bentley might still have.
