That would be Torque Power Manifolds for the gaskets.

Ah yep, that's them, never would have found them otherwise, cheers for that.
Looks like they don't do gaskets for the earlier style though, but I suppose no harm asking if that's a path worth pursuing.

Those still leak out of the gasket material, ask me how I know....

These days I always smear a little RTV around the coolant ports and cover any part that may come into contact with coolant. Effectively I'm using RTV to "seal" the gasket material.

The basic Permaseal ones will be fine (they could even be rebranded NZ Gaskets here), they have a very small bead around the ports but not really necessary in this application. Always use RTV or something suitable around the coolant ports, as well as the extra sealing there is usually some corrosion that needs filling and its a good way to stick the gaskets down so they don't move during installation.

Other side is a bit clearer, zero bond to the manifold face and you can see it just walked up.


I'm quite certain a better gasket will fix it no problem, just thought it was interesting how bad it was in a short time.

Let me know how you go sourcing those.
I ordered permaseal conversion gasket set yesterday and got a call today to say mid next month before they are available.

On another note, I'm running those TP intake gaskets and haven't noticed any issues in 6+ years.
I think I trimmed a back corner for coil mount clearance upon install, but that was all.

I hunted around and found someone who claimed they were in stock, according to the tracking info they've shipped. Price is ridiculous of course.

To me it almost looks as though the gasket wasn't getting good compression in the center and blew out.

It looks like it's an N/A application, so I wouldn't expect lots of crankcase pressure. But having silicone only on the outside coolant ports could make it thicker in that area and cause lower compression on the center of the gasket. It seems like overkill, but maybe add a small amount of silicone to all the ports?

A lot of the time the gasket issues are caused by having the heads and blocked machined and not taking into account the manifold and valley facing but boy that looks real bad to me with lots of movement occuring. Perhaps a few retorques of the manifold over time may help.
