[Mk2] [Turbo] HELP PLZ, turbo spooling in neatral

Post by turrall1 »

i was driving last nite and the 2 just cut out, i tried to restart and the battery seemed to just have gone dead, i bumped her and she started but was very lumpy, i drove it home but it would accelerate then loose all power, the clocks would indicate rpms, ie engine was idiling when i tried to accelerate and then just kick in in irregular bursts, it used 1/4 of a tank of fuel to get 5 miles and when i got home the exhausts was glowing red but under the engine bay wasnt overly hot and the turbo manifold wasnt glowing, now the turbo is spooling in neutral, not everytime but it seems to get worst when is is slightly warmed up, then when it is hot it is all the time, somebody please help

Thanks for the replies. Had it apart today and there's nothing blocking any intercooler pipes at all, and the inlet manifold seems clear. Although i can't see in the intercooler for any blockages. Even the intake and airbox are clear and nothing has any signs of damage.

Another thing i checked was the actual turbo, and although there's no excessive shaft play the intake wheel does not spin freely, and at some points feels slightly stiff. How easy should it spin? For example if i spin it should it keep spining for a second or not?

no it shouldn't be as free as that, although not stiff either, i'd get the timing checked mate, sounds like it's badly out, that's the only thing that's make the turbo spool when not under load :thumleft:

as Andy says, it may have jumped a tooth.

when you say "under load" what exactly do you mean?

I can rev my engine in neutral and set the bov off...surely this only happens when the blower spools up...
