My S3 was running underpowered and blowing a fair bit of blue, diesel smelling smoke.. I decicded to adjust the pump timing and things have gone from bad to worse..
Being a later model series 3, i was sure that the flywheel was stopped at exactly the 15 degree mark on the flywheel before i removed the pump.In doing this i did not pass the mark and rotate the flywheel back, i approached it from the direction of rotation only. When i took it (the pump) off what struck me was that the master spline looked to have been further past the 20 degree line from the horizontal as specified in haynes/workshop manual. If you ask me I'd say it was 25-30 degrees.
Nonetheless i inserted the tool and took the backlash up, turning the tool clockwise as specified. By now the master spline was at least 40-45 degrees past the horizontal mark scribed on the engine block. Re-positioning the pointer indicated an unachievable position of the pump, in that the pump is rotated as far clockwise as the mounts will allow. The pump cannot be positioned to the new position as directed by the pointer.
I re-aligned the spline on the pump to match that of the engine drive gear, and re-assembled the whole lot. To say that its billowing smoke now is an understatement, it's absolutley pumping it...!
Has anyone any ideas??
I'm thinking about using the tool to turn the drive gear anti-clockwise, back to 20 degrees and starting from there, but to be honest, I'm lost!!
I'd really appreciate any info anyone has on this one.
Thanks a lot - Pat
