Faulty oil pump?
Posted: Mon Feb 20, 2017 11:23 pm
Hi,
I had given my 1970, 1098cc 4 door saloon for non engine related work. Unfortunately for various reasons, the car remained with the mechanic for 2 years without starting.
After being started recently it was taken up a steep hill for testing on first gear at high rev(35 kmph) to a distance of 300 meters. On reaching the top of the hill we stopped & noticed that there was oil dripping (about 10 ml on the ground) around the rear cork sump seal. Few drops from the dip stick sleeve and a drop or two on the front tappet cover.
Thinking it to be a minor issue the car was driven for about a total of just 20kms over the course of the week. At the end of that, the engine oil had fallen below minimum level (was noticed since the engine was knocking).
A litre of fresh oil was poured (around minimum level or just below) & the car started for a minute. After turning off, he opened the oil filler cap & inserted his finger & touched some components in there. He suggests to me that they should be oily even if the oil is below minimum & the car is started for just a minute. He suspects the oil pump.
1. Should his finger have oil residue in the above circumstances?
2. How to know if the oil pump is malfunctioning?
The workshop manual (pics below) doesn't contain any information about identifying a faulty oil pump.
Multiple other problems (electrical, etc.) have cropped up & I want to start with oil issue.
Many thanks.
