Bildo Posted August 26, 2010 Share Posted August 26, 2010 Basically the car has been running spot on for about 8 months now, then I took it out for a drive tonight for the first time in 3 days. As soon as it started it felt more sluggish than normal, so I decided to keep my eye on the boost gauge.Where (from what I remember) my turbo used to kick in at about 3-3.5k and be at full boost by about 4-4.5 (guestimate) it has now decided to start at about 4.5-5k and not even reach full boost by the time I feel comfortable changing gear.I have gone round and checked the pipes for boost leaks, plugs and leads aren't very old at all, actuator seems to be hooked up like normal etc.Has anyone had a similar issue and resolved it? Could it be dump valve related as I've not yet checked this.Any input would be greatly appreciated as always.Cheers! Quote Link to post Share on other sites
bucketep91 Posted August 26, 2010 Share Posted August 26, 2010 checked for cracks in the wastegate? double check the pipes aswell matecould try blocking off the DV to rule that out too Quote Link to post Share on other sites

Blitz Posted August 26, 2010 Share Posted August 26, 2010 I had a similar problem and it was a crack in my manifold Quote Link to post Share on other sites
DavidAshton Posted August 26, 2010 Share Posted August 26, 2010 What are you using to control boost? Quote Link to post Share on other sites
Bildo Posted September 7, 2010 Author Share Posted September 7, 2010 Sorry for the lack of responses, had a busy few days.Little bit of an update for you all, not too sure as to whether the two issues are linked or not, but I've had a bit of an unpleasant evening:I'll explain more when I get a chance.

daz gt turbz Posted September 9, 2010 Share Posted September 9, 2010 arrr tits, bad time mates, whats gone on then? Quote Link to post Share on other sites
Bildo Posted October 16, 2010 Author Share Posted October 16, 2010 Sorry for leaving so long to respond to this. Luckily it wasn't as bad as I had initially thought, it was all pretty dramatic and had me fearing the worst. All that had happened is I was on quite high boost, combined with travelling at motorway speeds. There was a hairline crack in the turbo oil feed and the pressure had made oil spray everywhere. Luckily I turned the engine off before all the oil had got out and the engine's running fine again now.On a less positive note, I'm still not reaching full boost until 5k and it's starting to get really frustrating!I guess I'll have to check the dump valve, if its not then remove the mani and take the heat wrap off to check for any cracks, if not then I guess it'll be wastegate checking time.

Socks Posted October 16, 2010 Share Posted October 16, 2010 race-tech's braided oil feed/return is a godsend, the damage this sort of problem can do is VERY costly. potientially taking out the turbo, engine etc...So for the sake of £60, i know what id rather do! Glad to hear its sorted mate, fingers crossed you find somthing simple causing your slow boost times... Quote Link to post Share on other sites

I need to make sure I get this sorted first due to being a bit strapped financially. Quote Link to post Share on other sites
Ryan Posted October 16, 2010 Share Posted October 16, 2010 Have you checked your boost controller or actuator one of them could be causing the problem Quote Link to post Share on other sites

Note - You should feel the diffrence straight awaybut make sure you watch your boost gauge and keep it safe don't over boost for your setup.Cheap actuator upgrade Quote Link to post Share on other sites
