rubberdubber 0 Posted September 3, 2011 Hi all After having a 1.8 16v kr for a few years, ive gona and bought myself a vr6! Spotted it cheap in auto trader, its in tvr pearlesant paint which is hideous and will be re-sprayed when funds allow but it was a good price so cant complain too much. Anyhow got a few issues which i could do with abit of advice on, 1stly the plug for the additional water pump? (see pic) is missing, i assume it has been disconnected for some reason? i assume this is bad and needs to be re-connected? it dosent overheat atall, use or pressurise the coolant but assume it must be there for a reason! Its also running abit rough, mainly just at low revs, really poppy on over-run and dosent rev smoothly, any ideas? its got the following nasty after-market accesories fitted, possibly the cause? Also noticed whilst poking around under the bonnet that theres a spare outlet on the fuel rail, looks to be blank inside but thought id better make sure there shouldnt be something on it Many thanks in advance, im new to the vr6 world so any help from you experts would be mucho appreciated Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted September 3, 2011 1st pic,the aux water pump,they run when the engine is switched off,they are common to fail but do bugger all imop....leave it be. 2nd pic ,the filter looks well dirty,clean it or replace it,also check the wiring to the lambda sensor,its close to the rear engine mount,often corrode and cause over fueling issues... 3rd pic shows the idle valve air resivour with a filter attached? possible idle valve bypassed? you need to look into that further,possible overfuelling and poor running issues... 4th pic is the fuel pressure test kit connection,this is normal.

aide 0 Posted September 3, 2011 that 3rd pic is of an ekotek valve, probably one of the most successful 'go quicker gismo' scams ever - remove it asap, as the reasoning is horse****! from memory of their spiel, anything over 2ltr will require two of them to be fitted, having only one fitted to a 2.9 will cause the valve to be sucked open permenantly - allowing unmetered air into the engine cycle all the time - hence major idle issue!

CorradoVR6-Turbo 0 Posted September 3, 2011 yea but they are attached to the servo pipe and draw air in on over run...thats by the idle valve? thats a pipercross filter not ecotec valve. Quote Share this post Link to post Share on other sites

rubberdubber 0 Posted September 3, 2011 thanks for the replys chaps! Good news on the unecessary water pump and the fuel rail, also thanks for the tips on the running issues. Good few things to check!! Now for this ecotek debate, what the feck is an ecotek?? never heard of it, whats it supposed to do! Any ideas how i can remove it and put it back to how its supposed to be? anyone got a breather pipe picture or diagram? cheers people, really liking this forum! Will get some pics up tomorrow though a little embarissed as the paint and wheels are hideous. 1st things to go! Quote Share this post Link to post Share on other sites
aide 0 Posted September 3, 2011 do a google search for it, but don't believe the hype! just remove it and replace the pipe. Quote Share this post Link to post Share on other sites
