Weird location for a boost leak
Weird location for a boost leak
The only boost leak I have left is this area:
There is a a vacuum hose that runs from there to some vacuum tree that I assume was for all the emissions, the coolant neck from the block must have melted the rubber and now it's a bad leak. The reason it runs right by there is because there is a metal pipe that bend towards the coolant neck and that is the only way to run the line.
I'm just wondering if everyone's is like this. It seems like a stupid spot to run a vacuum line. I'm not even sure how I could fix it, another line will just melt through.
This is between runners 3 and 4, you can see the IACV and the coolant neck but I circled the line that is leaking.

I have no remembrance of what hose that is . I have 3 vaccum hoses on my motor. one to the FPR and map sensor ,1 to the brake booster ,and 1 to teh supercharger bypass actuator and that is it..If you could say where it starts and where it ends up it might jog my memory LOL.

I'm not feeling too creative on ideas for a fix, but if the hose is damaged the best bet would be to replace it and then take some measure to protect it from repeating history (like everyone had said). As for removing the manifold to fix it, I guess it depends on how creative you are ... but it would be A LOT easier to get to by removing the manifold... assuming that everything is attached to the manifold and nothing goes to the block or head or anything else that is attached to in in the engine bay.
Sry, it's been a while since my manifold has been off so my memory of this part is a lil fuzzy as well.

those things are not the most pleasurable thing to get to but typically the are hard as a brick and very difficult to remove . A stock intake is not the most fun to R&R either . I left mine intact because back during hte really cold temps I had considered using those ports to inject propane to aid in cold starting since E85 is so tough to get running in the really cold temps .
I feel for ya . Ive seen threads where guys have welded the things up or tapped and plugged then but I just replaced all of the little hoses and left it there and capped the end of the pipe that goes to the PCV valve and so far have not had any problems with it under 15 PSI of boost .I think whatever you decide to do whether you pull the manifold or wrestle with them in the car that you are in for a treat that you will have funny stories to tell about though.

Are you going to make all four ports go into one vacuum line/block?

There is no vacuum there, I think you are mistaking which ports were are talking about here. I am speaking of the nipple that comes off the VC (valve cover), I'd weld at least one more if you plan on blocking the PCV on the side of the block.L wrote:Why? That line is going to a vacuum block anyway.Kamilitaryman wrote:If you are going to block that port off, be sure to run extra vents on the VC to a catch-can.
PM me if you're interested in getting something powder coated!

Your circling in the second pic is poor. That thick hose goes to a thermostatic air regulator that opens and closes based on temprature. That valve itself could have a leak, the gaskets inside do fail. There is nothing that will rub against this either
That small hose is an emmissions line, I dont recall where it connects to but its inline with the evap system by best guess is that it goes to the volume control solenoid. If your boosted you should have this plugged upstream from the hardline anyway.
How do you know you have a boost leak? Did you try the soapy water trick to see exactly where its leaking from?
