Dash Rendar Posted April 9, 2007 Share Posted April 9, 2007 I got blown away by a Mini today. It was well embarrasing. I put my footdown and went straight up to 0.7-0.8 bar, then #2 comes on and it drops to 0.3 bar! This has been happening intermittently for a few days now. Sometimes it boosts to 1.2-1.3, but sometimes #2 just doesn't want to know. I'm told it's my VSV sticking? If that's the case, has anyone got a VSV they can sell me? I guess all you guys that have gone single wont need yours? Quote Link to comment Share on other sites More sharing options...
Steve Posted April 9, 2007 Share Posted April 9, 2007 I think i have one you can have. Assuming you mean the EBGV VSV. Will have a look tomorrow. Have you also checked all the vacuum hoses. No splits etc..... Quote Link to comment Share on other sites More sharing options...
Pig Posted April 9, 2007 Share Posted April 9, 2007 I have one, but mine was sticking too lol! Quote Link to comment Share on other sites More sharing options...
Steve Posted April 9, 2007 Share Posted April 9, 2007 Read this thread http://www.mkivsupra.net/vbb/showthread.php?t=35926 Sounds like problem no.2 Quote Link to comment Share on other sites More sharing options...
Dash Rendar Posted April 9, 2007 Author Share Posted April 9, 2007 Yes... problem #2! So I think I need an EGCV! If anyone has one of these (that's not sticking!) that they would be willing to sell me, then please let me know. Quote Link to comment Share on other sites More sharing options...
Ric Posted April 9, 2007 Share Posted April 9, 2007 i have one of these Edit, no i dont i have the other one, egbv Quote Link to comment Share on other sites More sharing options...
Homer Posted April 9, 2007 Share Posted April 9, 2007 I think I have one here. It did stick VERY occasionally though. Quote Link to comment Share on other sites More sharing options...
Mike M Posted April 9, 2007 Share Posted April 9, 2007 Check the EGCV vsv connector is on properly, I've just had this and because the clip is broken the connector works loose. Quote Link to comment Share on other sites More sharing options...
Dash Rendar Posted April 10, 2007 Author Share Posted April 10, 2007 Well, the symptoms from that link suggest it's the EGCV. But having spoken so a knowledgeable geezer (!!), I'm told the EGBV could also be causing these symptoms... Which would be good for me, because that's much easier to get to. I've had a look at the vacuum hoses around the EGBV. They're silicon hoses (the blue ones) and I can't see any splits at a glance. Quote Link to comment Share on other sites More sharing options...
Dash Rendar Posted April 11, 2007 Author Share Posted April 11, 2007 Now #2 wont come on at all. Quote Link to comment Share on other sites More sharing options...
Dash Rendar Posted April 11, 2007 Author Share Posted April 11, 2007 It's going to Pheonix on Monday. Hopefully they can sort it. Quote Link to comment Share on other sites More sharing options...
Mike M Posted April 11, 2007 Share Posted April 11, 2007 Does it get to 4k and feel dead, hard to rev? if so i would say its the EGCV for sure. Quick TTC test and check the EGCV opens up then fault find the VSV tucked behind the wastegate VSV close to the alternator. Quote Link to comment Share on other sites More sharing options...
Dash Rendar Posted April 12, 2007 Author Share Posted April 12, 2007 Yeah, it boosts to about 0.7, and then when the revs hit 3800 and it should switch to #2, the boost drops off to about 0.3 bar. It's happening all the time now. It revs just fine... Just doesn't go anywhere fast! As for the rest of what you said... I wouldn't really know where to begin. So hopefully Pheonix will be able to sort it out on Monday. Quote Link to comment Share on other sites More sharing options...
gaz1 Posted April 12, 2007 Share Posted April 12, 2007 exactly the same symtoms as mine, although we tested the egcv and the egbv with an airline then pressure tested the system to no avail, i always seem to have problems with the twins when stock and the new hybrids so decided to bring my single conversion forward;) Quote Link to comment Share on other sites More sharing options...
s3upra Posted April 18, 2007 Share Posted April 18, 2007 Yeah, it boosts to about 0.7, and then when the revs hit 3800 and it should switch to #2, the boost drops off to about 0.3 bar.

Dash Rendar Posted April 19, 2007 Author Share Posted April 19, 2007 Oh yeah, forgot to update. Well... It was all a bit strange really. In the couple of days before going to Pheonix, the car also developed a slight misfire, but only on idle. So I got the car to Pheonix and Mark whipped the cover off the engine and promptly diagnosed that the engine breather system had been hosed incorrectly for starters. So he sorted that out, replaced a shot coil pack connector, and replaced the sparks. Then he moved the vacuum hose going to #1, as this one was kinked. And now it boosts just fine!! 1.2 bar is back! Which is really odd, because if the kinked hose to #1 was causing a problem, I would have thought #1 would have had trouble spooling. Mark suggested that the combination of these other factors, while being no major issue on their own, could have combined to result in my car being unable to switch to #2. These problems aren't black and white, are they?! Quote Link to comment Share on other sites More sharing options...
