James100 Posted July 20, 2007 Report Share Posted July 20, 2007 fcp has copied the drawing from VADIS parts section.the weird thing is that VADIS has this presumebly incorrect drawing in their 2005 edition. then again how many PCV jobs this forum has done and the topic came up in 2007..i have a hard time following binglanx's drawing. what's the significance of the vacuum tube in the middle?Why dont we just put it this way. Look at your car and see how its hooked up on the top of the oil trap. I put my connections on just like they were originally, I still have the trap here with hoses connected to it. It is opposite FCP and the same as EEuroparts and Binglax's pics, same as pics in Haynes and Chilton manuals.If everybodys car is hooked up by Volvo opposite of the FCP pic what does this tell you? Case closed. :lol: Link to comment Share on other sites More sharing options...
bagodoosh Posted July 20, 2007 Report Share Posted July 20, 2007 Why dont we just put it this way. Look at your car and see how its hooked up on the top of the oil trap.well, problem is i'm stupid and have a tendency to take things apart without remembering what goes where. i did it a few months ago (~ 5000mi) and it appears i put it back according to vadis diagram.

Read here. Seems nobody really questioned it, they just did the FCP routing or the way it was on originally. I got my parts from EEuroparts anyway and just hooked up per the original way.Its come up before but no huge "warning","Fail" posted. Link to comment Share on other sites More sharing options...

The last hose we want to get clogged is the one that takes the fumes out. Also, the two openings, one for the head and the other for block are close to each other and if you connect the hose to air intake to the place where head hose should be it may suck up that oil coming out of the block, just my theory.

rivfader Posted July 20, 2007 Report Share Posted July 20, 2007 The picture of VADIS is wrong!!! That's not the only mistake they did. That's why many people I know who work for Volvo don't trust Vadis at all. Link to comment Share on other sites More sharing options...
bagodoosh Posted July 20, 2007 Report Share Posted July 20, 2007 so my understanding is, short term it doesn't seem to make a difference, in some cases -- apparently mine. my RMS leak was actually reduced after the PCV job with the vadis style connection.long term, it may clog up sooner or who knows.it doesn't seem that it impedes the ventilation process.man, i really thought i was done with that job. all these pcv threads and i felt so relieved. damn you VADIS, damn yooouuu.. :angry: Link to comment Share on other sites More sharing options...
bagodoosh Posted July 20, 2007 Report Share Posted July 20, 2007 i found this in VADIS:1 engine > design and function > 25 intake and exhaust > intake and exhaust > crankcase ventilation1.Oil trap2.Cylinder head inlet hose3.Cylinder block inlet hose4.Oil pan return connector5.crankcase ventilation hose6.PTC-nipple7.Vacuum hoseThe crankcase gases are removed from the cylinder block and to a certain extent the cylinder head to the flame trap (1) where the oil is separated from the gases and returned to the oil pan. The pressure differences between the upper and lower sections of the engine are equalized by the hose to the cylinder head.When the turbocharger cuts in the crankcase gases pass through the PTC nipple (6) in the crankcase hose (5) to the fresh air intake.When the engine is idling and lightly laden the vacuum in the fresh air intake in front of the turbocharger (TC) is missing and there is very little crankcase gas. Because of this a vacuum hose (7) is routed from the PTC nipple to a calibrated intake downstream of the throttle so that the crankcase gases are led directly to the intake manifold when lightly laden.The PTC nipple is calibrated to give a controlled flow of crankcase gases. Power to the PTC nipple is supplied by the engine management system main relay and prevents water vapor in the crankcase freezing in the fresh air intake terminal which would otherwise occur at low temperatures.The PTC nipple stabilizes at approximately 80°C just after the engine is started.

Geevs Posted July 21, 2007 Report Share Posted July 21, 2007 Great find Bago +1. I guess the matter is settled then. Link to comment Share on other sites More sharing options...
shurgen Posted July 21, 2007 Report Share Posted July 21, 2007 +1. I guess the matter is settled then.The pic of oil trap in the engine bay on this diagram is not correct. The opening for head on the oil trap is more towards the engine if I remember correctly. Link to comment Share on other sites More sharing options...
MrWinkey Posted July 21, 2007 Report Share Posted July 21, 2007 I'm a bit late on this thread but the back LH port(facing the car,pass. side goes to the valve cover and the first diagram is incorrect?Here look at this thread PDF page 14 shows it correct...I actually had to go look at my car cause you guys even had me confused??? http://volvospeed.com/Repair/knock_sensor.pdf I didn't realize there wasn't a Bay 13 tutorial on this guess I will have to do one?
