Oil filter replaced without filling with oil?

[phloop]

I've changed the oil on this truck twice so far and the PITA #@$%! filter location has made me decide to no longer prefill the filter. If Cummins/Dodge could have found a worse place to mount the dang thing, I'd be surprised. I'm just happy the filter is so small, if it was any larger I'd just leave the old filter on. I did notice that after starting the engine after the last oil change with out oil in the filter that the oil psi came up just as quick as with oil in the filter.

Prefilling an inspection of oil filter.

Just changed my oil here last week, I do pre-fill the oil filter an lube the seal. As far as forgein particules during pre-fill I try to watch for this. I noticed the Chevron Delo 400 15w/40 gallon container I use seemed to me is using a pull tab seal instead of just a foil seal. May have been there all the time, but I noticed it this time for sure. Some are saying an checking to make sure of no plastic or foil to enter the filter opening which is smart, but I also check the filter too after removing the plastic covering (before prefilling) for any small metal particules from the center hole threading process they do at the factory when making the filter, or possiblity of a bur on the threads. If I can I do pre-fill when possible on the oil filter (this statement is from the mechanic I use an have known for 35+ years). Other day as we where changing the oil at his shop He told me to fill that oil filter with that contaminated clean oil an give it to him to install on my truck.

Every old auto repair book proberly ever printed recomends prefiling the filter. Jusy about impossable on lots of equipment. my tractors the filter is on sideways. No way to prefill.

True DP the key word was (if possible). I've done it both ways I just perfer to pre-fill on the CTD.

phloop: long arms are a bonus I don't have any troulble getting the pre-filled filter up to the mounting location, although I will say that it's sometimes difficult to get the threads lined up right...



oh, and as for oil pressure coming up -- I understand that what we have is a movable idiot needle who's actual position is simply eye-candy: its designed to make the customer happy, not to actually measure oil pressure.



Forrest: you could be right on the Hondas, esp the later ones. I was refering to 1980s vintage adjustable valvetrains. My '82 Civic was an overhead cam. lots of parts in there under near zero oil pressure. On that CTD fill tube -- does this go directly to the pan so that oil does not enter the top of the engine directly?



yea, the Delo-400 is a pull tab with foil on one side. pretty easy to take it off. But extra precaution is definately in order when you pour from the bottle directly into the center of the filter. you don't want the pouring oil to carry anything directly into the clean side of the filter.

If there would be any damage done in the short time it takes to fill the filter, then you better change your brand of oil. There (with good oil) would be plenty of oil on the bearings for some run time while the filter fills.

I'm surprised nobody has mentioned cases where the insides/media of the filter collapsing under the pressure when one doesn't prefill the filter?? Yeah this probly won't happen when one uses a quality oil filter such as Fleetguard, but do you trust that el cheapo Fram or parts store off the shelf oil filter that some use and to not prefill it?? Even if the insides of the oil filter collapsing is BS, I'm not taking any chances. I prefill every oil filter IF I can. If the major engine manufacturers recommend prefilling oil filters why not do it?

Well, Joe... . I guess you have your answer(s)!

 

[Deezal Man]

Kinda did...

I'm with you on this one... This is the main reason I pre-lube. OH. . and for those who say you can't pre-lube a filter which installs horizontally... YOu can't fill it to the rim. . but you can add enough oil to wet the element. My experimenting shows that about a 1/2 quart will be absorbed by the element where you can turn the element sideways and nothing comes out. Granted... I wouldn't take a phone call in the middle of doing so... but it can be done.

Filters on cars have gotten smaller to reduce the filling time on empty startups. The time to first oil is not that much of a concern. All the good oils have EP additives and there is not much heat. But when the 1 1/2 quarts of compressed air decide to "blow dry" a spinning main or rod bearing under load ( even at idle the diesel rod and mains are under significant compresion load) do not blame dodge or cummins for the failure. They put in a large filter canisters and recommended pre-filling. If it were an econo box the filter element would be cheap and small, more to remove the chunks, and not give any problems because they are low volume and almost never prefilled. Does not mean that one person will have a problem even if they do it the entire vehicle life. Ask a fleet garage if they prefill the 3 and 4 quart filters on the 30,000$ class 8 truck engines. One failure in 100 vehicles due to not prefilling is too much for them. But might be ok odds for you.

Holy Moly Guys!..... Alright Already! Oo.



It was just a simple question... . I thought *LOL*



Next oil change Im gonna "half fill" my filter just so I can sleep better at night



"Open Discussion"is what makes this site so great to read.



Totally Awesome Truckin... to one and all.



Thanks,

Joe

Half filling it is THE way to go. Let it sit all night so the filter media can SOAK up the oil. Then top off filter the NEXT morning the rest of the way. Thats the way my MOTHER always did it and my MOTHER was NEVER wrong. RIGHT! Oo.
