Hello guys,
just "finished" fixing my 8 (new engine). It runs great but there is some issues I'd like to ask you about:
First there is 2 connectors in the front I don't know what they're for ^^', guess something on the airbox?

I don't know where those 2 hoses go too...

And there is that hose, every time I rev hot coolant comes out. I may have connected the wrong hose or something like that.


Hard to tell what goes where from the tiny diagrams a friend working at mazda got me. Hope you guys know what those are Thank's a lot

 

The top one looks like the coolant level sensor. Likely it is broken and when it is plugged in the light is always on

The other lines are all the jet-air and breather lines for the intake manifold. the metal parts go from the line sticking up in the last picture and attach at the rubber bellows into one of the plastic elbows. The other rubber lie is likely the breather line. Depending on the model year of the car it will either go from one of the plastic nipples on the rubber bellows to either the oil fill tube or to the rear of the upper intake near where the oil filter is

Hope that helps


Has your car thrown a CEL?

 

Yes my car has a CEL, well it's been sitting still for a couple of months and we just throw the engine in. I have the cobb accessport, but it says there is no cel lol
Thanks for the info about the hoses, it looks like i messed up and put the wrong hoses at the wrong place, will look into it tomorow after work when there's sunlight ^^'
Thanks again

 

Found the hoses purposes (after some search (lot of search) ) Breather lines, the hose with water is the one going to the TB. Hopefully I can finish assembling my car tomorrow after school as I finish earlier than work.

 

The hose on the right in the second picture, with a sharp 180 degree bend at the end goes to your omp vacuum manifold. Probably important! You'll need to take off the upper intake manifold to get to it. Mine is not connected in this picture, but the 180 degree side connects right here and routes forward in the engine bay to the intake accordion. Since you're down there, I'd check the condition of everything you can, including the four vacuum lines leading to each oil injector. (weird tenticle looking thing)

 

And btw, it can be easy to break that vacuum manifold, don't do it!

 

thx lifelongpilot, found it and it's all done, only thing that remains in my hand is this hose going from oil neck to Idon'tknowwhere, on the vacuum diagram the hose goes straigt before de TB, but in 2006+ models It goes somewhere else.


but... where? lol only thing that remains I guess

 

Doesn't 2006 and up have an oil catch can for that? I guess if you had to have one left to fix, that's probably the easiest. I don't know where in those models the catch cans are mounted.

 

That's what I'm looking for, I know the 2006 and up have a system because of the white cream in vaacum hoses but I don't know How it's made, can't find where goes what. I found that the hose goes to a service nipple, what even is that? x) thx a lot

 

found it! for the ones interested

 

Where does that hose connect? looks like it goes to the intake manifold? thx

 

That is the jet air, it connects to the lower intake manifold. But the picture you put of your engine bay, the one that isnt connected is supposed to go to the intake accordion. you have some extra hose on there that isn't right. Can you say, in order from top to bottom, those three connections are? That bottom one looks funky

 

wait, I think the one you have connected to the bottom elbow on the accordion is wrong. That is the one that needs to connect to your oil filler neck. I'm stealing this pic from the internet because my engine bay doesn't have the stock hoses. There should be a short one straight from oil filler neck to the bottom of the accordion

 

Your pic is a pre2006 model, look at the diagram i posted ^^ the oil neck doesn't connect there anymore, but yeah I switched the hoses that were wrong will take a pic when sun's back it's night time now

Thx for the info about the jet air in the exhaust manifold, only one i was missing

 

haha face-palm

 

found about the 2 connectors near the coolant reservoir, on goes on the trunk opening system, on the side of the engine, on goes just on the chassis on the outside (there's a hole in it near the coolant reservoir too, wide enough for the connector)

I've got no more CEL I'm glad, engine still takes it's sweet time to start hot but gonna change the starter and the coils for the BHR ones. Engine's new and I don't feel like having problems with this car because I did not change a old part.

Except for a little squeek squeek noise from the clutch (new clutch) probably because it needs to be bleeded again (changed the clutch line for a braided one and put air in the system like an *ss)

Thank's everyone about the infos and for your time

 

Awesome, enjoy that new engine!
