What Is This

[Gardiner]

Carry on with my inlet manifold saga
My 8v manifold which I am planning on using it has a pipe on left of manifold that is connected to maybe a emission type thing unsure really can this be blanked off ????
My other manifold has No hole going into engine.

i believe that is you Ehaust Gas Recirculator Inlet, you do have a 413/samurai right?...
and yes it can be blocked off it isnt important really, from what ive heard theyre more harm than good...

[Gardiner]

Would you say just make a plate and seal it over the 2 pipes ????

[Jay18]

yep thats the easiest way to do it, im not sure what theyre like on the sj's as i have a 410 which dont have EGR's but if there are any vacuum hoses connecting to the EGR valve block them off aswel, usually a small bolt that fits into the hose tightly works well, make sure you get another oppinion to make sure what im saying is right as ive not done it on an SJ before...

Can I assume that the 8v manifold was off an injection model as the egr valve is a electric type rather than vacuum operated. I see the manifold has a pipe to the heater but no pipe for the carb as a injection one won't need it. I see no reason why the egr valve can't be plated off and a tee from the heater pipe can run an SU adaptor heater and then back to the water rail.
As you say in your other post , link the tee to the water rail direct for now, just to get it running
