Hey all. I recently replaced the fuel pulsation dampener in my '90 V6 PU. Well, in the process of removing the plenum, I had to disconnect all those little vacuum hoses on the passenger side of the plenum. Well now I have a "port" and no hose connected to it. I know, I'm an idiot for not tagging all these hoses to make sure they all got reconnected ok, but I didn't. Now when I start up my truck, blue smoke comes out the exhaust. I'm guessing this hose is the reason for that. Here's a pic of which hose I'm talking about....

the bottom circle shows the "port" and the top shows where this "port" comes from. If someone could do me a favor and check their PU and see where this hose connects to....?


Thanks!!

 

Is it the PCV valve? The PCV should have a U shaped hose going down.

 

The Small Hose Goes To The C/c Vac,large Hose Is Brake Vac

 

Where exactly is the C/C vac? Theres no other open port to be seen for it to connect to. :\

 

blue smoke- that doesnt make much sense- that means u are burnin excess oil- i dont think it could have much to do with those lines- ive run without many of those lines before on the same engine- it idled rough but no smoke- u sure its the hose fault- excess oil could mean a lot of things from burnt valves to broken piston rings- or oil left on top from a recent rebuild

 

well i figured that's the reason because it never really happened before that. no recent rebuilds. so... those may be a possibility. it has 240k+ miles. but, smoke only comes out when I start it up, and that's only sometime, not everytime. as for the hose... i noticed something is coming out of that port and it's all over the side of my engine. so that leads me to believe it's somewhat important. I dont know if it's gas or what, that's why i posted this. and trust me, if there's anything I dont want leaking out of my truck, its pricey gas. on top of that, my power steering is essentialy busted, and so is the clutch master cylinder. i have clutch fluid all over my carpet now... GRRR. plus my water pump leaks coolant. ::sigh:: this poor truck's seals are ALL WORN OUT. damnit!!!

anyways, any more info would be great!! ;D thx

 

just reading my post i realized that probably IS GAS. the blue smoke is probably because bad fuel/oil mixtures... ??? yeah, no?
