Oil change

[haber rj]

I understand that when you go to take the oil filter off when doing an oil change that the there should be a certain amount of old oil contained in the filter, if the valve is working correctly. My question is this, do you add oil to the new filter before installing it like you would in a normal car or just put it on.

Haber rj, I've not tried to fill the filter when doing an oil change and it seems to not affect anything. I agree about the filling of the filter, I used to do that on my 72 vette. I don't do it on the Z. I noticed that if I don't use the car for a week and start it up the pressure takes a few extra seconds to show on the gauge. The same thing happens when I start it up after doing an oil change, it seems to take a few extra seconds for the gauge to react.

Don't know if I should be filling the filter or not. I figure the car cranks so long before fire occurs that how much wear could be happening...I don't know?

Tom my reason for the question goes back to the information that was posted on the site about the AC filters (retaining valves) not retaining the oil when the engine is shut down. Apperently Mr. Herbeck (I am not sure if it was actually him) or his name just mentioned did a test or recieved some sort of information of the oil filters and said that the only filters that retained the oil after engine shut down was the Mobil 1, Fram, and K&N. The valves that keeps the oil in after shut down worked well. In my opnion (now I am getting brave) if the oil stays in when the engine shuts down, why would it not stay in when you put some in when changing it. I am going to try this when I change my oil in the Spring before taking the car out of storage. What filter do you use on the "Z",

haber rj,

Yes I remember the thing about the filters and the drain back valves! I made a mental note to use either GM stuff or Mobil1 M-207 filters. Mostly I use the Mobil1 M-207 filter and I can say that if I use the car enough I don't even get chain rattle on start up. Therefore I think that the mobil1 filter must have a good drain back valve. If the car sits for a week without use then I get the rattle on start up with either GM or mobil1 filters. I haven't tried any others because I can get the GM or mobil1 filters easily.

I haven't had the chain rattle in a long time and believe me my car sits for weeks, sometimes months. On to another subject the chain tensioners, have you ever heard of anyone changing those, and if so were they hard to do apperently they are only plastic pieces and one side is easier to change than the other. I think that I will also go with the Mobil - M207 filter, are these available at Auto Zone, we don't have Auto Zone up here, but I am alway in Buffalo or Michigan so I will buy 2 or 3 and keep them on the shelf.

I make it a good habit to fill my oil filters up with oil before installing a new filter.

[haber rj]

FU2, I have to agree with you I do the same, but I haven't been doing that in my "Z" car. When I do the next oil cahnge I am going to put some oil in the filter and turn it upside down (over the garbage can) and see how much oil if any leaks or drips out, should be interesting

Let the oil soak into the filter. You will be suprised on how much oil will be soaked up by the filter media. After one or two filter changes you'll know exactly how much oil that can be put into the filter without it coming out.
