air bleed with plenum coolant bypass

As gorgeous as that engine looks in the pictures above, it looks even better in person! It is simply AWESOME!

Thanks Paul.....it may be all coming off if I can't pass emissions in Nov....We'll see.

Boy I hear you there Rich. That's why i sold everything and went back stock. Well almost anyway. Passed with flying colors here in Idaho even with the Flowmaster Cat-Back.

Ada and Canyon (where I live) Counties in Southwest Idaho require smog checks biannually. DEQ Nazis wouldn't give me a waiver for the air injection system and it was just going to cost much to retrofit everything for the AI and cats. Even then no guarantee I would pass, that's why I removed the headers and chip. Now I have Marc's piggyback chip in so I can remove it easily and just have the stock chip in for smog.

Well in PA, if you get Classic tags (15 years or older), an emissions test is not required. Another benefit is once you pay the $142, it's good for life, never have to register again. Just get it inspected once a year. The downside is your only suppose to drive the car once a week (no way anyone would know that but you) and the tags are purple.

I may be wrong, but it appears to me that the crossover hose set is only brought up to circulate hot water around the throttle body. THAT I bypassed when I bought the car new. I just ran a rubber hose under the plenum to connect back to the tank. I like the look of plugging the water ports. It looks to me that the large coolant return tubes carry coolant back to the upper radiator hoses from the same place as the TB heating hoses. There would be no air pocket as the main returns are located in the same place. I would rather cool down the plenum and ram tubes as much as possible.

I had bypassed the coolant from around the throttle body on mine back in 1990, as I had done on both my 1985 and 1989 cars. I actually showed that trick to Guldstrand when he was at my shop in 1985.
I DO like, since I'm not using hot coolant around the throttle blades, to eliminate that hose system that returns back to the overflow system. I will be powdercoated the entire top side of the engine in Silver miniflake soon. It seems to me that with the water returns just under the plenum, that there could not be any air trapped there.
IF there was an inch of trapped air in the plenum ports, all the better. I don't want any added heat into the plenum.

I found the picture below of my injectors at FICs website with the blue plastic caps and double O-rings. Just to be safe I emailed FIC to get their input. I'll update the thread once I hear form them.

I spoke with the techs at FIC. The blue caps on the tip of my injectors are called "Pintle Caps". Their only purpose is to allow you to remove the injector without dropping the O-rings in the manifold. They are going to send me a few at no charge and I should be able to pop it on without much effort. They said I could put it back together as is without the cap, but since it's apart anyway might as well put them back on.

That's 'cause you got RC's, you rich *******.
