Mk2 T5 Dump valve

[thebadger]

Ok, I'm aware of all the "wooo you can't do this, it'll break, or not like it" talk.

You need not apply to this thread. (thanks but I'm trying this one way or another...)

3 things I need help with.

1. What size of fitting kit suits the Mk2? is it the same as the 850/v70 mk1?
will this do? http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWA:IT&ih=020

2. Where does the vacum hose go to? Any quick & obvious pipes?

3. Which pipe does the valve attach to? I think it's the large one down the right side of the engine (bout 1/2 way down the side of the engine)

I'll do some pics to help me show what I mean. (tomorrow or sat)

Cheers in advance for any help!

(anyone else done this on a mk2 V70 T5?)

Hey Badger

Not sure about the ME7 engine, but here's mine:



Assuming that your engine is almost similar to mine, here's what you'd do:

If you remove the black throttle housing cover (See the yellow circle in the above piccy), you'll find a little "Christmas tree" (as some folks call it). You'll see 6 little stubbs coming off the "Tree". Simply pull one of the small plastic plugs off of one of the tree's branches and attach the thin vacum pipe that comes from the top of the Dump Valve.

Here's mine attached and set up:

Yup mines is identical to that minus the spangly bits, looks very tidy indeed!

[thebadger]

yeah, no such pipe or bits on mine!

I'll need to get the camera out!

[thebadger]

Ok, here are the pics I have of the ASSUMED area of the dump valve.

The yellow hose, I think it's the VACUM hose.

The red arrow pipe, I guess this is for the DUMP VALVE.

The Vac house for the dump valve is doown the front of the engine.

The dump valve is on the side of the turbo.

ME7 engines don't like dump valves from what people have posted here and on other sites. It may be worth going through a few different posts to make your mind up on the matter.

As if by magic.... the fitting kit arrived about 3 mins after I posted the pics!

Cheers alan, but my first post says I'm doing it. end of.

The Fitting kit instruction says...

the hose to fit the BOV is the hose between the intercooler & throttle body.

I think my pic of the vac hose is right (yellow arrow).

[thebadger]

You can see the "vacum" hose in the second picture (green dob on it).

The one with the red arrow at it does go to the bottom of the intercooler.

[thebadger]

the only other pipe I could guess it would be, is the one over the top of the engine.

[thebadger]

ok, I have confirmed that the pipe needed (for the valve) is the MASSIVE one, right over the whole engine! (you'd have thought I'd would noticed it!)

Anyways, my big question now is.....

do I ,

A. Cut the pipe, buy hose & fit it up top?

B. Fit to the intercooler hose end?

C. Fit it at the head of the turbo itself (back of the engine bay).

I cut mine

[thebadger]

I cut mine

The pipe, or the hose?

[Rob_ioClean]

Hose if poss, apprantly(no to sure about this) the closer it is to the throttle body the better!

yeah, my fitting guide said the same.... not much use when it's a pipe it's going on to!

[thebadger]

Ok, got some hose (not hoes) off fleabay, £3 per dod, 2 dods req. I'll get my jubilees from halfrauds or B&Q. (probs B&Q)

Of course, I could ask halfrauds to fit the jubilees.... nahh!

I'll detach the intercooler end, cut out a section about 3.5" (using a hoover to keep the plastic flecks from going to the turbo end) then fit the hose to both ends, then the T piece.

What say you guys?

[thebadger]

ok, valve was in today!

I have been looking at a http://www.forgemotorsport.com/index.aspkit for Volvo and at some forums for info and was looking to find a good link to installation diagrams for your car but cant remember where i saw them but here is a good discussion on the uses and applications for BOVs , its from http://volvospeed.com/vs_forum/index.php? Cheers LesM.http://volvospeed.com/vs_forum/index...V+installation I suggest you go down the thread to a guy who explains the reasons for [ avoid the idiotic comments !! HA HA ] Good luck and see if you can post video of the sound of that trumpet!!
