Trying to figure out how to fix this mess that i didnt create. I wanted to look into my pcv system cause i am leaking oil somewhere behind and below my combi valve.
Currently there is a c-shaped tube from the metal feed line on crankcase breather tube (i dont know if anyone else has this 5" tube) that was attached to a check valve flowing to the right meaning toward the sjp and then a short rubber section attached to another check valve going in the opposite direction (so yeah it has been doing nothing) and that was on a short rubber piece connected to the small branch off the SJP. I think it was thrown together wrong. I have no idea what it should look like because i read my engine hood diagram could have a mislabled direction of check valve and it is very confusing diagram to begin with. My bentley diagram is just as bad since half the items are not where they should be. I wish someone could create a 3d diagram. Anyways, can people describe how theirs is connected to the SJP from the feed line prior to crankcase breather, and confirm that i must have 1 too many check valves there? According to diagrams it looks like i am missing a t section but unsure. Here are some picts:
There was a metal check valve next to a normal plastic check valve and they were canceling eachother out, i think the plastic one was reversed by accident as i could tell since it had one section with its original one time use clip on it. I added red arrows to the direction i was thinking they should go but i think i have it backwards and am confused.
according to this video, fast forward 5 minutes in https://www.youtube.com/watch?v=Wdp8gJHTXmE&feature=youtu.be
the c-shaped tube that i have is supposed to be s-shaped and that the pcv valve is supposed to connect from it to the branch of the sjp ! i dont know what is going on with my engine then, since my tube connects over to the metal feed tube of the crankcase breather tube.
Your profile says you have a 2003 1.8T AWM. Is that correct? (The vacuum lines vary a bit over time.)
The Etka diagrams might be the closest thing to a 3-D drawing I know of.
This is my 2001.5 AWM, which is probably similar. Not perfect pictures, but maybe a start.
Note the check valve that's right on top of the suction jet pump is the oddball three-port check--the third port is on the left side in the photo (right side of car); it points towards the rear of the car and connects to another check, with flow toward the three-port check (i.e. towards the intake manifold).
Thanks for posting. Yes it is a 2003 engine in my 2001.5. I haven't had a chance to talk to my mechanic who swapped out the engine, but i am thinking the guy who had this 2003 before me probably did something wrong (i bought it from a junkyard) and then maybe my mechanic just didnt notice??? Here is a pict of looking strait on at the back of my engine and the c-shaped tube that was connected to my branch off the sjp i gather should be an s-shape with a pcv on it, but then i dont know where it is supposed to connect, it just stops right there? What connects to the metal feed tube off where currently i have the c-shaped tube still connected? I have admired your pvc clean up many times. But i am wondering how stock is supposed to go. the diagrams are horrible. Do you have a pict of whats going on more to the left toward the combi?
according to this diagram
i must be missing a T and the pcv and the s-shaped tube. though i dont really understand how the thing to the right of the green tube on the diagram is the pcv. I wish i had a good picture of what it would look like in realife though if anyone has one... I know now that i drew my red arrows in the 1st post going in the wrong direction and that they need to go toward intake. So once i know what parts i need to order from ECS, i will order so feel free to make suggestions. Still dont know what goes on that metal feed tube on the breather tube off crankcase though...
Well i am still stumped where one sets up the pcv valve. Here are 3 parts i was thinking of getting as a kit
but have know idea where to put the large tube since the youtube video said the pcv is on the s shaped tube of of the SJP branch. maybe i will buy the pcv and the t connector and an s tube but still have no idea how to set them up. Does anyone recall any pictures anywhere that happen to show them. It could be on an unrelated topic i just need some images of the back of an AWM engine bay where the pcv may be visible. I need to order parts but have no reference to go by. I have a bentley and apparently it is useless in this department since i cant understand its schematic.
here is my engine:
i have 03 awm engine, thats all i know.. i will look up pictures and try to find out the difference. Are AWM 06A blocks? i see that amazon told me that set up does not fit my '03 but it would have fit my '01. Ok, well i need to figure out where my pcv valve is still and have not found the t section under my intake. I think my dog leg is old just looking at it and probably will need to replace all that anyway.
i was thinking i could have something like this? would this would for an 06A? he has a "euro jet upper y hose" i have something similar that the puck comes off of the side of it. VWVortex.com - DIY - 1.8t Lower PCV Hose install, pics!!
i was looking at this thread and the blow up diagram was useful but it says the bleeder valve #6 is not a spare part for this model. what is that supposed to mean, can't buy it? then there is 6A which is shaped like a t and has a hose connecting off of that which is similar to what is attached to my crankcase. ARG! i just need to know what goes where to order parts. The breather valve that goes in the block is connected to the t that is connected to the bleeder valve (pcv) with has 2 branches, one branch to retaining clip 28 one to 12, what are they connecting to? where is my SJP in all of this? http://www.passatworld.com/forums/b...rs-misfiring-could-caused-ignition-coils.html
I have the breather hose (on dog leg) that connects to block, then a t (maybe the pcv in there?) that branches with a curvy hose up to a metal pipe that runs along underneath valve cover. it is damp with oil and that runs next to combi which is damp with oil, and it comes around the otherside behind the heatshield.
I guess I didn't finish my thought on that last post, where is my sjp connected to if one end of the t goes to metal pipe along valve cover and the other goes to the intake? I can only assume other engines may have the pcv on their sjp but I dont With a late awm 2003. should I go with a silicone replacement piece of the lower breather cause that's the only compatible part with my '03 awm, rest of kit not applicable.
Does this shed any light on how my SJP needs to be routed (below quote)? oh and i read somewhere that my bentley doesnt even show how my 2003 engine is specifically done so this is why i am asking for help from forum members, its not like this is easy to find out. I have spent hours reading different threads, looking for pictures that are half the time dead links. Please help me figure out how to route my sjp small branch... if anyone has a 2003 or 2004 stock, can you just take a picture of how it is routed. or if it not stock, how i could route it? Before mine had two check valves going against eachother so that was obviously useless.
"I will be doing my '05 AWM on Sunday but I'm not planning to change the suction pump despite common advice I've read. From all I've read on the 1.8T PCV systems they always stress changing the suction pump because it gets clogged from crankcase crud.On my AWM's system the suction pump's angled port is routed to the gensing root right after the air box. The top port goes to the brake booster/vacuum bottles and the bottom port gets manifold vacuum(pressure). All seems fairly clean to me, don't really see the need." 2011 akullander http://www.passatworld.com/forums/b...-cleaning-oil-gasket-[detailed-pictures].html
The question which keeps going through my mind is just how much of each PVC system (old and new engines) was mix and matched with a few other parts to result in what you are dealing with now? If I were in your shoes I would strip everything currently present and reassemble according to an accurate ETKA diagram for your specific engine.
i concur. I think my mechanic and his helper and the previous owner of the old engine which had also been worked on with 170k with multiple mechanics and other owners, had made it a real problem. I think i will go with how this etka diagram is, i just need another etka page that shows the sjp? dont know where to go to find that, any ideas?
The Etka diagram is the clearest one I know of, relatively speaking. The routing is all there, but some parts are shown is different physical locations and orientations so you can still see everything.
The suction jet pump is item (19).
Regarding the third leg of the 3-port check valve (22): it goes to another (ordinary, 2-port) check valve (50),
which then goes to a molded hose with 3 legs (38). It connects to the short leg.
The longer two legs on (38) point toward the left side car and supply vacuum to the two vacuum valves (both 31). These valves are:
> N112, SAIP valve, operates combi valve, toward rear of car
> N249, pilot valve for DV, toward front of car
The end of (38) toward the front of the car is plugged (it's just rear of the dipstick). The end toward the rear of the car connects to an elbow and thusly to a hose leading to the vacuum reservoir, which is hidden in (I believe) the wheel well.
Yes, i know that now. its all mixed up and going to try to fix it. The hose from the side of the bleeder was going up to the metal pipe (#73) that runs along the back of the engine, and i know now that the sjp was supposed to go that way. On my car #73 then has a cap on it, so doing nothing.So basically the branch of the pcv was going nowhere. my sjp branch went to tubes with check valves in opposite direction and over to the metal small hose from valve cover. I have no idea if my pcv system has been working. Also dont know if this is why i am leaking oil, but i think there must have been build up of pressure in my crankcase and probably seals are now leaking..
now i need to find out what is the part number for item 75 on that etka diagram and which port does it plug into on the air intake? My air intake may not be the right style, still trying to look into that, most of the ports are difficult to see from above. As long as i can plug #73 into my intake i think i will be able to start ordering parts.
i found an ebay item that ought to help me figure things out: http://www.ebay.com/itm/Air-Intake-Boot-Duct-Tube-1-8T-01-5-05-VW-Passat-058-133-356-P-/281401307248
i bought the 2003 intake piece from ebay (last post) andhope to install it in place of the 2001 version that i have. I dont know if i would run into any issues, but it looks doable.
Wanted to give an update. My breather system update is complete. Car running well and no issues on VCDS. I will take a long drive tomorrow to the highway and that will be the real test. Hopefully no smell of burning oil anymore when I get off the highway.
