It's there, I've installed a new vac pump.
Problem was the oil pump.
Thanks

The 1.6TD Quantum CY engine was solid lifter and used the pump with 30mm gears.  If your engine has hydraulic lifters and a turbo/oil jets, then you should use the pump with 36mm tall gears.

Thanks for the info. It's a turboed NA with mech lifters, no oil jets. The oil pump is bigger then the original one that i removed.

If you don't have the hydro lifters or oil jets then the 30mm pump is fine.

What?  30mm is fine?  Bigger is always better.  Well unless it is a bill to the electric co.
