The small screw on the oil filter housing is to drain the oil from the filter. After you unscrewed the smaller bolt, you have to attach the small plastic drainer cone, which starts the oil flow. Then, you can unscrew the whole oil filter unit with that tool and the oil won't flow into your face as it had been drained previously. If you have no plastic cone next to the disposable filter element, you should not unscrew the smaller center bolt as you cannot drain the oil and the oil flows as you remove the filter assembly.
Yes that true. I think its just waste of time. Next time i will leave the smaller bolt on and just unscrew the whole unit. I ask in dealership mecanic if they do that and he say that they dont unscrew smaller bolt because it doesnt matter

@@igoris992 I also skip this small bolt in the greater majority of cases.
Sometimes it is worth opening it to avoid screw stuck and o ring failure.
nice job
Is this engine timing belt or chain?
I think that it is timing chain
Diesel engine has a belt, which must be replaced at the specified intervals. Only the vvti petrol and hybrid engines have timing chain.
This 1AD FTV is chain drive engine
@@igoris992 wow. I was not aware of that.
