Many questions :) I'll be brief...
How can you tell what size a garrett turbo is, i see the little plaque thing but it hasn't got anything i recognise. Only has an oil feed, no water and i think i read T28's and up had a coolant feed?
What sort of affect would a leaking downpipe have? Tis leaking really bad at the min about a foot down the exhaust at a join.
Ever since last night its not boosting properly. The boost guage goes from -10 to 0 but no further. Still pulls okish at 0. Possible leak somewhere? Its not as dead as it was the other night when a turbo hose blew off tho. Wastegate still makes a bit of noise when you let off the trottle too.
Maybe just coincidence but the boosting prob happened about the same time as the downpipe leak, its possible it leaking right up where the turbo joins the downpipe but i can't be sure.
How stiff should the actuator be? This ones very stiff and bent which i know can't be good but it never went over the 6psi it is (was) running. I think i have an old T28 somewhere i can nab one off if they're the same.
Car is a 1993 renault 19 2.0 turbo, not many of these about so i doubt anyone has any experience with them LOL
Ta peeps :)
