MANIA 0 Posted October 19, 2006 Report Share Posted October 19, 2006 So, I've got this MK3 VR6 which came with the unexpected bonus of a VSR intake manifold. What should I look for to tell if it has all the associated bits that go with the manifold itself?And where's the ECU so I can have a look and see what chip is in it?

richievr 1 Posted October 19, 2006 Report Share Posted October 19, 2006 that certainly is an unexpected bonus!!!!the ecu is under the black plastic trim at the bottom of the screen (under the wipers)you should have a vacuum tank , some hoses , and the appropriate chip in the ecu ..does your car have a dizzy or a coil pack ???

MANIA 0 Posted October 19, 2006 Author Report Share Posted October 19, 2006 yup, bonus alright! I have a green plastic ball - is that the vacuum tank? There's LOTS of hoses - I'm used to Morris Minors! It looks like it's got a coil pack at the back right looking at the engine from the front Link to post Share on other sites
richievr 1 Posted October 19, 2006 Report Share Posted October 19, 2006 yep green plastic ball is the vacuum tank ....so it has a coil on the bulkhead with a single lead coming out of the middle doing to the middle of the distributor cap...????that is a result for you as your VSR should be controlled from the ecu with its own special chip......

richievr 1 Posted October 19, 2006 Report Share Posted October 19, 2006 i'll take a good pic of my engine bay for you so you can see what extra hoses etc are needed. . . Link to post Share on other sites
MANIA 0 Posted October 19, 2006 Author Report Share Posted October 19, 2006 Yup one lead from the cap to (what I assume is) the coil pack on the bulkhead.I'll have to take some more pics when I get home (the wife has the car) and I'll check out the ECU side of it. Link to post Share on other sites

antera309 3 Posted October 19, 2006 Report Share Posted October 19, 2006 Whip off the DOHC-VR6 engine cover and you should be able to see the vacuum solenoid, its actuating rod and the lever for the manifold flap in between the two inlet runners that go to the throttle body.This shows the underside of a VSR manifold, just so you know what I'm talking about!:Get someone to step on the throttle and raise the revs gradually. As soon as the engine hits 4000RPM, you should see the lever move. Let the revs drop back below 4000RPM, and it should move back to its rest position again.If it does this, your manifold is working and no further diagnosis is necessary.Although having said that, next time you have the opportunity to take the manifold off the car, take the flap mechanism out of the manifold and inspect the condition of the flap - there should be no cracks, and it should be securely attached to the spindle. If there are any problems, get them sorted - you don't want bits of flap breaking off and entering your engine!! Most Schrick manifolds are too new to have this sort of problem, but the VW VSRs are getting quite old now. Better to be safe than sorry! Link to post Share on other sites
MANIA 0 Posted October 20, 2006 Author Report Share Posted October 20, 2006 That's great thanks, I'll check out the flap functioning this weekend.In the meantime here's a couple of pics of mine. Link to post Share on other sites
