It's all ball bearings...
The build on my 94TT is keeping it interesting. It appears that whoever owned it 2 owners back did some head work (port & polish, Ferrea valves, Ferrea valve guides) but not all (stock original valve springs, retainers etc). Anyone know why someone would do the valve work, specifically the Ferrea valve guides, and not do the valve springs? Particularly when the car has miles on it (103K now), has the original springs and the car was at most BPU +. Also, are the Ferrea valve guides oversized and do they indeed wear rather quickly? The head guy said the valve guides were in there very tightly and was hesitant to knock them out before having properly sized replacements. Any help would be appreciated, the car just keeps killing me
