an oil extractor will never get as much residue out of the bottom of the pan as will draining from the drain plug will.
And its real important to get out as much of that as possible on every oil change.
oh dont tell him to use what the factory recommends
I made the mistake of doing that on this board and I was shamed for not knowing what I was talking about, I was shunned and felt fuggin dumb for about a minute
then I got over it
I think mine uses Method 2, I would have to check
One of them is "trans temp" not "trans fluid temp" that one is the one that is close the coolant temp. I thought that might be the temp of the trans itself but I dont really know. That is the one I tried using originally
Method 1 was just not...
I would change the fuel filter while you are under there.
Actually I would have changed it before the pump if it has not been done
When was the last time it was changed?
could be a bad compressor. Try rotating the compressor hub by hand (engine off of course) and see if you feel any resistance.
If not probably a bad compressor. But really hard to say for sure over the internet
thats why I am suggesting an oil pressure test.
I am not saying what is causing the noise since I do not know
All I know is there are other possibilities besides the tensioner/chain
that all I am saying
I am sorry that not always the case. In my many years of doing this for a living I have heard rattling on startup that goes way on engines in the very early stages of low oil pressure problems.
This is why whenever I buy a used vehicle I always insist to hear the motor startup when cold and I...
I will give you the same advice I gave the op test your oil pressure you can rent a gauge from a parts store if you don't want to buy one or have it done by someone who knows what they are doing
because oil pressure is building up and making up for the excessive clearance in the rod or crank bearings and quieting the rattle.
And yes bottom end knock can go away after startup if its just starting to go bad,
Very common I used to see it all the time on motors going bad when I worked on...
