Haha, alright, hope all goes good, I'll keep you posted, I'll be doing it tomorrow. So just get some vaccum line and fuel line? What size? Thanx again. And DO cap the little nipple between the primaries?

Chris

 

I didn't have to mess with the oil injector lines when I did the rats nest did I? So they should be all set right?

Chris

 

Yes cap it. But a vacuum cap assortment, about 5 feet of 5/16 fuel injection fuel line, and I want to say 3mm vacuum line. You may want to take and old vac line with you though.

 

Yeah. They should be fine. The spider thing that hooks to them goes to the larger fitting on the backside of the TB.

 

One last question, in pic 3, under the cold start thing, what do I do with this? Its a sing vaccum line. Thanx

Chris

 

More cap action.

 

Haha, thanx for all the help, sorry to be such a bother too, just wanna do it right the first time.

Chris

 

Last question, what about the hose that goes to the abck of the TID? Cap it too? thanx again.

Chris

 

Yes. Glue something (like a small bolt) in the hole where it was.

 

Question about the charcoal canister. Keep it or not? And if so, what do I do with the line off the canister? Did it hook to the TB or something? I'm lost. Everything else went good, just don't know what to do with the charcoal canister. Thanx

Chris

 

i removed my charcoal canister and capped the hard line on the driverside firewall

 

But if I were to keep it where would I run the other line to? Thanx

Chris

 

The fuel line is 5/16 internal diameter

 

I did, all is good, however my buddy just removed his fuel pressure solenoid(every other one was gone) and we put it all back together, just like mine and nothing. It doesn't even get fuel. What did we do? Anyone ever had this problem? Thanx

Chris

 

did you hook up the return and entry lines from the fuel pump correctly ? that would be the first thing to check... otherwise i'm not sure what else it could be?

 

The thing is though, that everything ran fine, he had already removed everything except the fuel pressure solenoid. We decided to remove EVERYTHING last night to see if it would help with his idle and now the car won't start. We're lost. Hmmmmm.....

Chris

 

my car has zero solenoids. but it's a S5...... i'll think about it for a bit and see if anything pops up. if not recheck everything

 

Vacuum lines do not connect to the oil injectors. The oil injectors have hoses going to them that supply air from the air pump. If vacuum lines are connected to oil injectors, than oil would be sucked into the intake and burned in the combustion chamber. Your car would smoke like a SOB! LOL!

not positive,but i think u are wrong, i believe the vacuum balances the pressue so the injectors don't pump tons of oil in.

 

The air bleed lines on the oil injectors are to help atomize the oil. They get atmospheric air on the NA's and pressure air on the turbo's. Same on the fuel injectors.

 

Where do you think the oil goes in the first place? To lubricate the apex seals. And where are they? IN THE COMBUSTION CHAMBER!

"Most of the 86-88 cars we have had the intake manifold off of needed most, or all, of the little vacuum hoses for the oil metering valves. On a few of them, those hoses were the entire poor idling problem. We just get all the hoses (5) and the black plastic "splitter" block, and sell them as a "kit". The turbo cars are much more prone to this problem due to the temperatures the turbo itself generates."

 

 

OK, now that we've discussed the oil injector vac hoses, any ideas on what would the problem would be with my friends car?

 

i changed all those to shiny red hose tech silicone when i put in the second jspec

Compare the diameters of the orifices in an oil injector with the diameter of a 4mm hose -- a few thousandths of an inch vs. a few hundred thousandths of an inch. The result is that the oil injectors admit extremely limited amounts of oil into the combustion chamber compared to what a vacuum hose would suck into the combustion chamber.

Did you ever check the vacuum hose routing diagram in the Mazda FSM or even the Haynes manual? Well, if you did, than you should have noticed that there are no vacuum lines connected to the oil injectors. The oil injectors are connected to air bleed lines.
