Last Saturday, I drove my brother to buy an auto part for his car in my 2003 corolla.I decided to change a valve on my crankcase cover(PCV Valve) which had been blocked for about 2 months due to smoking.I must emphasize that I never had issues with the car.The auto spare part dealer said we should buy a complete crankcase cover with the valve since he wouldn't sell the valve alone.We got the cover and opened the engine top to replace it but were shocked to see massive sludge that had formed flakes.The cover we got didn't match anyway so we decided to clean the old one and put it back.On starting the car,the oil indicator initially went off then came up after some minutes.This has continued with further checks pointing to the oil pump not pumping enough pressure .I bought a new oil pump (Briscoe) put it after some of the sludge was manually removed with diesel.The oil pan was removed while doing this.I also changed the oil and oil filter still the pumping is still low.NB I change my oil at regular interval with mobil oil.Please I need suggestions on what to do

Call Yinka on 0802 558 3908; he should be able to sort you out.

Thanks Onwan.More suggestions needed please!
