The V8 Owners Forum -

I installed my intake manifold last week. I am not using a heater matrix and so need to connect this to bypass. I believe I have the EFI flapper manifold. The injector ports have a circular step inside which I believe is identifies it as such, casting is ERC9119. I do not remember seeing a threaded boss underneath but have since seen photos of manifolds which show one where the heater pipework is plumbed. I do not really want to remove the manifold to check I have one or not. I do remember seeing a couple of threaded holes underneath to accept small screws for brackets.

Vieiwng the manifold from the front I have the thermostat housing and to the left I have a thread boss. I also have a steel inserted short pipe on the right hand side front, I am thinking these two are the heater feed and return and I presume I can just connect these together. I also had on the right hand side near the front but on the top a small steel pipe insert which I assume is maybe a feed to the throttle body water jacket?

I also have a flat platform on the top left hand side front which looks like it used to have something mounted on it but it is not drilled.

If it is flapper (which I think it is) then the flat platform thing is for the old stepper motor thing.

As for the plumbing, its similar ot my old pent-roof manifold. I too have removed the heater matrix, and yes just Teed the heater plumbing together - I have a header tank in place of the heater matrix now. The small connection which you think is for the throttle body water jacket - I just Teed this into the feed from the top of the header tank to the radiator overflow connection.

Hope that helps

Cheers mate, so no plumbing into the underneath of this manifold like others?

just done mine, not pretty, but there's not a lotof room there !

Mines a bit different, water pump does not have a T, its the NAS cover and later water pump I have. My themostat housing points to the right. I do not have a connector at the back of the water pump either. What is screwed into the left hand boss, looks like a sensor cannot make it out and the water temp sensor is on the right top.

Thats the sensor for the gauge, mines a P6 set up, with the narrower pump, didn't realise the later pumps haven't got the other outlet ! john
