francis Posted July 12, 2006 Share Posted July 12, 2006 I'm wondering the same, I have a UK TT6, it's done 113k miles and doesn't have any problems that I know of, no smoking etc. I double decatted along with a CW SMIC and Fluidyne Radiator about 4k miles ago, I don't intend on raising the boost and it's boosting to 1.0bar at the moment.... hopefully it'll keep running smoothly for a while yet!

Suprasteve Posted July 12, 2006 Share Posted July 12, 2006 Type: Jspec 6sp manual Age of car: 1994 Time since going BPU: aprox 12 months Miles before BPU upgrade: approx 75,000 Miles recorded since BPU: approx 15,000 Boost level: max 1.2 bar Problems: None *touches wood* Useage: admittedly i'm very heavy on the right foot, but isn't that the whole point of having the power otherwise i would have bought a Micra:p Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 12, 2006 Share Posted July 12, 2006 That's all very nice. But the other side of the coin is all those people who fitted hybrids or singles --- didn't a *good* chunk of them experience BPU-Kaput? The market isn't exactly flooded with used JSpec turbos.

Homer Posted July 12, 2006 Author Share Posted July 12, 2006 I don't believe so John, on either point. I was hoping some of those that upgraded to post their results here too. Quote Link to comment Share on other sites More sharing options...
SUPRALOOPY Posted July 12, 2006 Share Posted July 12, 2006 BPU time/ 2 months, miles on car 77,000, boost 1.1 bar, miles used 4,000 at the most. PROBLEMS..valve stem seals,turbo seals(maybe/definetly) Quote Link to comment Share on other sites More sharing options...
chilli Posted July 12, 2006 Share Posted July 12, 2006 well all instances of valve stem seals are totally unrelated IMHO so lets disregard them in the context of this thread. Be interesting to know what is up with yours for sure supraloopy, thought we were doing well but there will always be failures - even brand new fails sometimes!

But i'm going down the turbo route ATM. Does anyone know how to get the pcv valve out of the cam cover? although i don't think this is the problem as ive srayed it with carb clean till the can ran out hhehehe:d Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 13, 2006 Share Posted July 13, 2006 ... ive srayed it with carb clean till the can ran out hhehehe:d Make sure that the carbcleaner is marked as 'safe' for oxygen sensors. It doesn't take a lot to poison them. WD40 is the worst. Quote Link to comment Share on other sites More sharing options...

Pig Posted August 31, 2006 Share Posted August 31, 2006 I had probs after about 10k of BPU i think it was the actuator. this made the turbos perform irratically (some times number 2 would not come on etc) P.S DONT buy second hand turbos Quote Link to comment Share on other sites More sharing options...
mattanna Posted August 31, 2006 Share Posted August 31, 2006 Well my aristo which has done 98,000 miles now need oil pressure switch and prob big end shelves doing and i am looking at a bill of about £2000, it is not bpu, so the bullet proof theory on these engines is fast losing credance with me[ANGRY][/ANGRY] Quote Link to comment Share on other sites More sharing options...
jase_93tt Posted August 31, 2006 Share Posted August 31, 2006 Mileage before BPU 64000 Mileage now, after BPU (1bar) and Single turbo upgrade 73000 Problems - none (touch wood!) Driving style - 100 miles per week @ 50/50 light/spirited Quote Link to comment Share on other sites More sharing options...
supRo Posted August 31, 2006 Share Posted August 31, 2006 BPU Approx 1.5 years. 85K miles at start of BPU 50/50 -1.0 to 1.25 bar - 50/50 light/spirited current mileage - about 111 K miles (will have to check) 3-4500 mile oil changes (using Shell Helix 10/40 and silkolene 10/40) Turbo timer always used (Probably excessively! lol) Problems - None There was a time when I did get 'blue start up' smoke when I used Optimax. I then switched to Ultimate/Tesco 99 and I've not had the start up smoke for about 8 months. Guys if you do have the 'blue start up' smoke and use Optimax, try using the other brand petrols for a few weeks to see if it stops! Quote Link to comment Share on other sites More sharing options...
