Hey, all.
Very basic question. Does pressure in the oil pump increase with rpms?
A couple of months ago I was tooling about on some backroads - not
aggresively, but definitely working the tranny a bit.
I'm accustomed to rev-matching when I gear down now. Just habit.
I was dropping from 3rd to 2nd at about 40km/h or so. I blipped the
throttle to rev-match (~2500rpm), and for a half-second I smelled
something burning. It dissipated immediately. Then, next 'blip', I got
the same thing.
This was at the tail-end of a 4-hour drive through the mountains. I
haven't had the same symptom since.
A couple of *weeks* ago, I got a hint of smoke coming out of my hood
scoop. At that time, I was driving very sedately, just driving along
the in-city highway, at about 60km/h. I stopped the car, popped the
hood, and there was a small bit of smoke close to the area of the
turbo.
It dissipated quickly, and did not recur.
I went in to the dealer, and they diagnosed a small leak in the oil
pump seal. They resealed it under warranty.
I'm guessing that the burning smell a couple of months ago, and the
smoke a couple of weeks ago are explainable by the same thing - oil
pump seal leak. My question would be - could my 'blipping' of the
throttle up to 2500 when rev-matching into second be a bad idea,
speaking from the perspective of oil pressure etc? Or is this just
likely a bad seal that was gonna go anyway?
Thanks,
BD
