Jonathan Posted March 18, 2004 Report Share Posted March 18, 2004 I was filling my car with coolant and now it started to leak from the adapter plate ! In near the rear of the car where the heater hose attaches. Did I put the plate on correctly? I put the adapter up against the head and the gasket then the manifold. Did I need to put another gasket between the head and adapter? Jonathan Link to comment Share on other sites More sharing options...
Boosted_One Posted March 18, 2004 Report Share Posted March 18, 2004 I don't have an adapter, Glenn filled the coolant passage and closed it off a bit. However I would think you would almost need another gasket... how would that plate seal properly unless it was ungodly planed perfect? Link to comment Share on other sites More sharing options...
HotrodTSi Posted March 18, 2004 Report Share Posted March 18, 2004 I went ahead and got an extra gasket...trying to get everything in place before I start this project. Link to comment Share on other sites More sharing options...
Jonathan Posted March 18, 2004 Author Report Share Posted March 18, 2004 Opps my mistake I do have another gasket on their. So its gasket, adapter plate, gasket, intake manifold. Should I even use the adapter? Jonathan Link to comment Share on other sites More sharing options...
Joel Posted March 19, 2004 Report Share Posted March 19, 2004 You must use this adapter. I promise 2 gaskets (one on each side). Aussie gasket should go between the adapter and the manifold, and on the head side of the adapter will be a US style intake gasket. Joel Link to comment Share on other sites More sharing options...

Ray_R Posted March 19, 2004 Report Share Posted March 19, 2004 What a pain in the a**.... Take care Shawn i agree, why did they start using the adapter plate? mine came with that water port welded up and cut out to fit. i wonder if that can still be done? seems like more work to fabricate a plate and more chances for something to leak now that the area has been doubled. there must be some other reason.

Joel Posted March 20, 2004 Report Share Posted March 20, 2004 Supposedly it was done so that way any of us that switch to an Aussie head won't have to undo the weld up job... just remove stupid plate and thats the end. Oh well. Joel Link to comment Share on other sites More sharing options...

WTFISIT Posted March 20, 2004 Report Share Posted March 20, 2004 I paid an extra $50 Canadian to have the port welded up. Link to comment Share on other sites More sharing options...

Jonathan Posted March 22, 2004 Author Report Share Posted March 22, 2004 I should not be working on cars. I reversed the gaskets to the adapter plate. All is well now. Goes to show you that you need to take your time and think things through more than once. Jonathan Link to comment Share on other sites More sharing options...

Boosted_One Posted March 22, 2004 Report Share Posted March 22, 2004 Ya guys, pay the extra $$ and have that coolant port welded up. Link to comment Share on other sites More sharing options...
Joel Posted March 23, 2004 Report Share Posted March 23, 2004 Ya guys, pay the extra $$ and have that coolant port welded up. I wish i knew about it when i bought mine. Mine was one of the first of the batch that started this whole adapter plate fiasco. I had to retorque damn plate again today, Blegh. Joel Link to comment Share on other sites More sharing options...
conquestpa Posted August 8, 2005 Report Share Posted August 8, 2005 How come I never got an adaptor plate? I got a unmodded magna intake manifold and Chad moddified it for me. I had it test fitted with a gasket I made up, and ran it, no leaks. But now I have a slight coolant leak coming from the somewhere around the intake. Its very possible that this is leaking from somewhere else weird around there. Im also curious about what type of gasket we would use here if we wanted to buy one. I assume you could buy one for the US style intake manifold and make it work. Link to comment Share on other sites More sharing options...
conquestpa Posted August 8, 2005 Report Share Posted August 8, 2005 Whoops, here's my answer from another thread: You can use the stock gasket where it meets the head. The rear water passage is resized so it has everything the same as the stock intake (atleast on the ones I mod, don't know about the others). The plenum to manifold seal can either be cut, or use some RTV glue (gasket glue). It's just air passing though there, no water/oil so that should be plenty safe, cheap, and easy.
