turbomoose Posted June 15, 2005 Report Share Posted June 15, 2005 Have the intake manifold off to replace the oil vapor line that goes from the oil vapor / PCV box on the block to the intake boot on the turbo... Does anyone suggest I do anything maintenance wise to the car while I have all of these parts removed?? :) Link to comment Share on other sites More sharing options...
Che'_Moderator Posted June 15, 2005 Report Share Posted June 15, 2005 Good time to polish the manifold. I would also replace that evil little piece of rubber that connects the hard line to the fuel regulator. Link to comment Share on other sites More sharing options...
prasamin Posted June 15, 2005 Report Share Posted June 15, 2005 that's a good pic man....thanks alot....i say clean out the oil trap, or get a new one if possible....replace the vac line from the side of the intake manifold to the turbo hose, and wire brush all the oil lines down there....i guess you could polish the manifold too if you're good with that kind of stuff!!!Clean the EGR if you have one down there, clean the TB out too! Replace the intake manifold gasketwhen you've got it all back together, Seafoam the car, and then get the injectors cleaned and balanced and stuff....good luck, let us know how it ends up!

turboV70 Posted June 15, 2005 Report Share Posted June 15, 2005 how do you remove the intake manifold? I've tried to before but there are bolts somewhere that are keeping it on... Link to comment Share on other sites More sharing options...
turbomoose Posted June 15, 2005 Author Report Share Posted June 15, 2005 The new vapor hose from the oil trap comes with a new vacuum line that goes to the side of the manifold... which was another thing I needed to replace. So that's covered. Ill try to clean out the oil trap... and I have not found an EGR valve... just the air pump valve, which is new according to the Prev. Owners records. MY TB is REALLY clean and shiny, I havent touched it. Not one drop of oil or a spot of grime on it anywhere. The intake manifold is fairly clean inside too... a little varnish by the mating surfaces of the manifold/head. I know I should clean the idle valve too. Need to get some replacement vacuum lines from the dealer tomorrow too. Mine look kinda toasty. And Im not into polishing the manifold. I hardly open the hood so it serves no useful purpose to me. Its nice to see other volvos with them polished tho, but as far as "mods" the only thing I'd do is use some tire shine. :D Link to comment Share on other sites More sharing options...
turbomoose Posted June 15, 2005 Author Report Share Posted June 15, 2005 There are two 12mm support bolts on the bottom of the manifold, if you feel around you'll find them. Link to comment Share on other sites More sharing options...
RK850 Posted June 15, 2005 Report Share Posted June 15, 2005 TurboMoose,How's the inside of the manifold look? Is it coated with black grease-like stuff? I once had an Alfa 164. When I removed the intake manifold, the inside was coated with lots of black 'stuff'. I cleaned it w/ with some F.I. cleaner and engine felt smoother and had more power. I was thinking to do that on my 110k mi 850 but just curious how dirty is yours. some pic will be nice .RK850 Link to comment Share on other sites More sharing options...
RK850 Posted June 15, 2005 Report Share Posted June 15, 2005 by the way, how long did it take to remove the intake manifold? Difficult?RK850 Link to comment Share on other sites More sharing options...
turbomoose Posted June 15, 2005 Author Report Share Posted June 15, 2005 It wasnt hard at all to remove the manifold. Just make a mental map of where everything goes and what bolt goes where. I myself have always been excellent at this. My father on the other hand cant remember how to put anything back together.here are a few pictures of what I've been playing with... Cant wait to get my paycheck later this afternoon so I can go get some carb cleaner and clean out a few parts. Im shocked by how clean everything is at 122K This is the Compressor Bypass Valve (CBV) mating surface on the turbo. CBV CBV InternalsThe dirtiest port I had on my intake manifoldInside the manifoldInside the turbo discharge port... sorry for the blurAnd finally, I found this mystery hold on my valve cover! Is there anything missing? Or is this just some odd vent>?! Link to comment Share on other sites More sharing options...

Looks like an easy job really. Link to comment Share on other sites More sharing options...
turbomoose Posted June 15, 2005 Author Report Share Posted June 15, 2005 Thanks Doc! It's a LOT easier working on this car than working on a VW VR6 engine Ill tell you that much. You dont have all of that VR6 engine cover junk to remove. Other than that, they're very very similar in design and layout. Link to comment Share on other sites More sharing options...
RK850 Posted June 15, 2005 Report Share Posted June 15, 2005 Your manifold looks pretty clean. The black stuff in the intake port is what I was taking about. On my Alfa, the entire manifold was coated with that. Did you get new gaskets for the manifold and the injectors? The Haynes manual says they are needed when removing the manifold.You need to plug that hole. Something definitely missing there I saw your OE air filter. I think you need a K&N to unleash all those turbo power RK850 Link to comment Share on other sites More sharing options...
slilley Posted July 9, 2005 Report Share Posted July 9, 2005 I have the exact same hole on my '98 V70XC, which I have owned since new. No one seems to know what it is for, and I suspected the oil that I was finding on the top of the valve cover was coming from this hole (it looks like you've got exactly the same coating of oil that I had). Last summer, I plugged the hole, using the two adjacent screw holes, a metal plate, and a rubber stopper. The top of the engine is dry now (at least it was last time I checked it 6 months ago; I need to check it again when I do the annual maintenance this summer). However, this hole must serve a purpose, since I've seen it now on at least a handful of othe cars. Most people don't notice it, because it tends to fill up with oil so it doesn't appear to be a hole until you wipe it clean. Anyway, I hope I'm not doing any damage by keeping the hole plugged.

merlin390 Posted July 9, 2005 Report Share Posted July 9, 2005 if you remove the two knock sensors on the side of the block mark their orientation and DO NOT use air tools on them!!!!the clamps might be a PITA to take off of the oil trap but there are 3 hoses and 2 bolts Link to comment Share on other sites More sharing options...
