Hi all,
Ive got a rack ive rebuilt myself using locally manufactured (australian) seals to rebuilt a 205 Si rack (so non-gti rack which has 2.8ish turns opposed to 3.2) using std spline drive. engine is an rfs gti6 with a 306 cabriolet (n3?) pump
its had about 5 hours of use before it blew out the top pinion seal, it was coming out like a fountain, as i was pulling into a carspace, and it had some very hard driving the day before. im yet to dissasemble it to check whats gone wrong, but im after some advice as i suspect I may be correcting a symptom not a cause.
My thoughts are ive nicked one of the high pressure seals inside (and the top one that blew out is just a dust seal more than anything, not designed for pressure), or scored the housing, the pump has a faulty pressure release valve or ive just used the wrong fluid. I used a castrol version of dextron III.
Advice/thoughts/criticism?
Much appreciated.
