How does the oil pan pick up screen and crank shaft look like

calculation:
Weldone for the job. Please what is to blame for this?

sultaan:
Is the right side of the engine missing chain guides?


I think they never changed the oil just topping it off.

If it was changed the gunk won't build up like that. The owner might be saying one thing but since none can actually say they saw the oil changed work with the worst case scenario.

We have a Toyota 4runner 2007(V6). 1GRFE with the following fault errors pulled out from the pcm

1) P0016- crankshaft position-camshaft position correlation (bank1 sensor a)

2) P0022- camshaft position 'a'- timing over ratarded(bank2)

3) p0012- camshaft position 'a'- timing over-retarded (bank1)

4)P0456- evaporative emission control system leak detected (very small leak)

Symptoms exhibited by vehicle:

1) oil light flickers
2) so much internal engine noise
3) sluggish movement

Diagnosis:

** Since oil light flickers, an oil pressure tester would be used to determine oil pressure from the oil pump using an OTC oil pressure tester. After this is done a comparison would be drawn based on what the manufacturer recommends

N.b oil pump is an internal part within the engine

a lot of sludge and worn our bearings

Engine comes down.

Following to see what happens next.
