Hi, please help me. My tuck is running extremely bad so I decided to run a compression test on it, which gave me readings of 180 psi on all cylinders except number 3 and number 6 which I got 185. But I am not sure if the gauge was even working right because after every check it would not relieve the pressure once I finished and pushed the button. Anyways, looking at the hoses attached to rear top of my plenum and PCV valve I noticed that the long hose coming off the PCV valve elbow was not connected to my pcv valve, I disconnected the hose that was hooked up to the plenum itself back above the PCV valve and when I did water came out of my plenum. I checked my oil dip stick and it does not look to have water in my oil at all. So what do I do now? Can it be fixed or is my whole engine fried now. What, if anything can I do? Please help

Hi,

I need to get some clarification. Coolant is coming from the PCM hose? I ask because PCM runs between the throttle body and the valve cover. There is nothing there where coolant can get to. Are you sure it is the PCV?

I am sorry, I should of explained better, I think someone changed the hoses around (on purpose) and put one of the coolant/heater hoses on my plenum, I don't know. All I know is that I removed a hose from my plenum and water was coming out of the tube on my plenum. I don't know which hose it was or where it connected to. What should I do?

Hi,

Not a problem. It has been awhile since I have seen one of these. It has a heated PCV system. Not that I better understand, there is coolant going to it. If you see the attached picture, let me know if that is what you are seeing.

Actually I thought it was coming right from my plenum it actually it is coming from at top hose that in that round circle that you circled. When I remove that top hose that's where the water come out and now it's all rusted. What should I do? Is that worse or what? Do I need a whole new motor now or what can I do? It's all rusted, so I got to be something fast. Please help as soon as possible. Thank you so much.

Also, I don't know if I should mention but somebody bypassed my heater hose heater core as I know that has something to do with the heater hoses I think right?

Hi,

Don't worry. The part you are referring to can be replaced. As far as the heater core, chances are it was bypassed because there was a problem with the core leaking into the vehicle. I attached a picture of the routing of water lines. Do me favor. If you can upload a picture of where it is leaking, it would help me. Also, is the rusted component leaking through a rusted area or from a connection?

As far as the heater core, are there two hoses running to the firewall of the vehicle?

The part that is all rusted is the little stem part where the hose is attached to on that part that you had circled in the first pic you sent me, where I pulled the top hose off of and water was coming out of. I don't know which hose I pulled off or what the other end was attached to. I think it was one of the hoses on the heated PCV ring that goes around PCV valve. It was definitely not the right one, I am sure. As far as the Heater bypass goes the "Mechanic" that I had change my water pump said that my heater core was bad so he bypassed it, However, I did not have water on my floor board, in fact my truck was leaking a lot of green antifreeze underneath the truck. Yet my truck never got hot at all. Weird. And please know that all this basically began after taking my truck in the shop to have my entire coolant flushed out due to another of rusty looking water. It took the shop less than 5 minutes to "complete flush" and they put in gold antifreeze they said, yet all that poured out was green green.
So basically yeah they mixed antifreeze and here I am. Please, please help. What can I do? Should I remove my Plenum again and see what is inside or what? I cannot seem to attach a pic of the part for some reason. But it was the top hose off that round thing circled in red. Please tell me what next. Thank you

Do you need help with heater / PCV routing? Also, were you leaking any coolant prior to having it serviced and was the heater working?

Let me know. I wish I could see what you are dealing with. I suspect when the heater core was bypassed, they rerouted the heated PCV hoses as well and that's why they look wrong. I can tell you that the supply line that went to the heater core first went through the PCV heater then to the firewall (heater core), The return from the heater core will run back to the engine.

Let me know.

The hoses connected to and from heated PCV going into that round thing on my plenum is what I need help with. (Actually both things).I actually can't remember if heater was working or not but I will start from beginning and please tell me what you think.
My truck was losing a lot of water turned out to be one of my freeze plugs (driver side) so I replaced it, stopped leaking. But while doing so I noticed that the inside of the block was real rusty with a lot of rusty stuff so I thought I better take to a shop and get a professional flush of the whole system so that's what I did. $175.00 later I drove home from shop truck running terrible. So once I got home I looked at my coolant in my reservoir and it was green, looked at my receipt from shop and they stated that they had flushed all old out and filled with gold. I immediately called them mad as can be. Next day went back down there telling them they need to get that gold out of my truck and that they did not do anything except ruin my engine by mixing the two together. They basically said too bad, and would not fix it. From then on my truck began leaking a lot be of big puddle of green, green antifreeze, yet would not get hot at all. So took it in to someone else to put in new water pump he said need to bypass heater core and cut off the 2 big heater hoses coming out of fire wall and looped them together. No more leaks. Now we got other problems. I took off plenum and changed out fuel injectors and put back together (possibly hooking those hoses wrong) I noticed the wires on my connector to my coolant temperature sensor were bare so decided to replace the whole sensor (underneath the truck) and accidentally broke the sensor off inside the motor. The truck is running extremely bad, very loud noises, no power, shaking, even when I make a turn I hear a loud grinding sound. Well I looked at it and that's when I removed that hose and water coming out of it. ( The thing you have circled in first picture top hose)

Hi,

Can you take a picture of the hoses you have? I will try to determine a way to remedy the issue. Also, if you broke the coolant temperature sensor off in the engine, chances are that is why it is running poorly. The computer uses information from that sensor to determine the air/fuel mixture. If you can, send me a picture of the broken sensor so I can see what needs to get that taken care of.

Please understand that it's a bit difficult for me to truly recognize what is happening with the hoses. Since someone has changed the design and without seeing what you are dealing with makes it really difficult for me. I try to envision what was done, but it is only theory for me.

Let me know.

Hello, Sorry taking so long to reply. The concern that I have with water coming out of one of the 3 hose ports that comes out of this round part that is connected to the top back passenger rear on my Plenum. (Which was most likely due to wrong hoses being attached, I assume) when I removed the hose. One hose I believe was attached to my heated PCV valve which is located underneath that part. I was unable to take pictures due to the location of the parts so I do not know what to do. That port that I took the hose off and water came out is now all rusted so I am afraid so is my inside of my Plenum and motor. What should I do? Should I take my Plenum back off? Is my engine fried? Please help. I am totally stuck. Thank you

As far as rust or corrosion in the cooling system, it isn't uncommon. What you need to do is simply flush the system. Do that when everything is back together. Here is a link to help:

Don't worry. This isn't an uncommon event.

Take care and let me know if I can help.

Okay, now this I guess is the part that connects to my Plenum (rear) (the round thing top left corner) that 3 hoses connect to and where I removed one and a lot of water came running out of. Now it says that 2 of those hoses connecting to it are for coolant and 1 connects from the PCV. (Is that correct?) Now what would happen if the hoses got switched and one of the coolant hoses got connected to where the PCV hose should of been connected and vise versa?

Hi,

If you connect a coolant hose to where the PCV goes, coolant will enter the engine.

That is what I have been trying to figure out here and need help with. If in fact that is what happened and that guy did switch the hoses around like I thought he did and that is the reason why when I disconnected that hose (do not remember which port I took the hose off of)from that thing that is why all that water came running out of it because my engine is full of water. So what then? Do I need a new engine? What can I do or have to do to determine if that is what happened? It does not look as if I have any water in my oil at all, (it is not all milky). So please tell me what I need to do to see if my engine is now full of water and damaged or what? Please

Hi,

The easiest way to check is by the oil level. If it is extremely high, then you know there is a problem. Also, water is heavier than the oil, so if you drain the motor oil, water should come out first.

Let me know if that helps. I'm sorry. I wish I was there to help. It is so much more difficult when the vehicle isn't present.

Hello, okay, now if there was water in my oil my oil would be all milky looking wouldn't it? I did drain it and it appeared to be a little watered down and not very thick but it was all just a dark black color like normal, which however really should not have been that dark seeing how the oil was just changed and only probably had maybe 20 miles on that oil. Anyways, so I am assuming that is a good sign showing that my Engine is not filled up with water then, right? Now is there any way that you can give me a picture or something showing me how exactly the hoses are connected to the Heated PCV valve and that 3 valve round thing connected to the back of my Plenum. I need to know which hoses come from where and hook up to where? (Both ends) if that make sense. But please do not send me a diagram of the hose routing for my truck because I do not have a clue how to read them, or maybe you can draw me one to tell me specifically in detail the location point of each end of each hose (those hoses mentioned above only) cause this stuff is getting all confusing. Lol. I know that 2 of the hoses that go to the round part on Plenum are water hoses and I guess 1 is for PCV? However, I don't know which one is which or where and what they are coming out of. Please help!

Hello, I'm Danny.

Sorry, you're getting confused with all the diagrams being sent to you however, we're just trying to figure out what was bypassed or switched in hopes of getting all this corrected. If you can it would help us out by using your cell phone to take a picture of all the hoses and connections and upload here to give us a better idea of what has been mis-routed to cause these problems. We do have diagrams to correct the problems. We are not trying to confuse you. Hope this helps and thanks again for using 2CarPros.
