AC Delco Oil Filter PF63... Questions on Filter Revisions....

Looks like all the 10522 oil filters in the Wix on-line catalog have the 'WL' prefix. The 57060 does not.

When my nephew asked me last year to get him a WL10255 filter, I asked him. "Are you sure?" 'Yep' The number seemed completely foreign to what I had seen from WIX.

WL10255 on the left, 57045 on the right.

The WL10255 has the same number of holes, but a different shape. It will interesting to see if WIX revises the hole count to match the newest PF63. Also the WL10255 is slightly shorter. I don't have a PF63 to compare to.

On a side note, w/ the new truck, I now have 3 57045 filters that nobody in the family has a use for...

When I went to exchange the 57045 I had bought, the 1st WL10255 I checked was made in Mexico, the 2nd filter was made in the USA. This was @ the same O'Reilly's store in New Hampshire.

If the specs & tooling are the same, they should look the same.

Wife and I did our Honeymoon in Mexico.

They got flush toilets and paved roads, better than Illinois. Who knew, right? :rollin:

So the PF63 was 'revised' for newer versions of the LS motor, how does the higher bypass pressure affect the lubrication system of older motors?

I think two of the reasons people avoid Mexican sourced products is the outsourcing from Canada & the US. Also does GM lower the price on a Silao built crew cab compared to 1 built in Ft Wayne?

I think when my plant closed in 2009, the wages at Silao were a tenth of the ones in Oshawa.

Yes sir, I expect so. It's why they are there. $$$$

Just making the point that quality isn't dependent on the dirt the factory is sitting on.

I lived a long time in El Paso Texas and of course the sister city is Jaurez Mexico. Wife worked for a auto parts supplier in the US that used allot of across the border labor and paid them US minimum wage. They lived in Jaurez and worked in El Paso is what I'm saying. Our house at the time cost 10 times more than that same house in Jaurez and so minimum wage in the US allowed them to live quite well in Mexico. Point being that the US suppliers benefit from the lower labor cost IF they source in Mexico, but the labor pool is doing fine. They live in nice houses, eat nice food and drive nice cars. They are skilled and make a good product. Unlike the garment industry in China. Trade with another country is a two-way street.

Yes but what about the employees that aren't in a plant in the US paying US wages? Silao is closer to Mexico City than Brownsville.

That's a good question. Keep in mind the oil filter bypass valve opens when there is a pressure difference greater than the valve rating THROUGH the filter media. In other words you could have 80 psi going into a PF63 (22 psi relief) and as long as the pressure coming out is at least 58 psi the bypass valve will stay closed. The function of the bypass valve is to allow the engine to maintain oil pressure even if the oil filter is plugged. The concern GM had with oil filters that have 15 psi bypass valves in newer engines is that under certain conditions those engines could develop enough oil pressure to open the bypass valve even though the filter was not plugged, which would allow unfiltered oil to circulate through the engine.

So then, would there be any issues with using a 22 psi bypass filter like a PF63 or 10522 in a Gen. IV LS? I would think that if you left the oil filter on long enough to plug up you might see slightly reduced oil pressure as a result of the higher bypass valve setting than you would with a PF48 or 56070. Then again both the PF63 and 10522 have more filter media in them and should be slightly less restrictive and take longer to plug up. The oil pressure sender is on the gallery right out of the oil pump so any issues with the filter would likely show in reduced oil pressure. I have on occasion used PF63 and 10522 oil filters on Gen. IV 5.3L's and 6.0L's without any issues and I have been told some dealers do the same.

You can see the bypass valve in an AC Delco filter looking through the center hole. It appears that the 15 psi valve is orange and the 22 psi valve is yellow.

Interesting trivia- the Gen. III LS didn't use an oil filter with a bypass valve, the Gen. III's bypass was in the oil pan. The reason the Gen. IV's went to a metric-thread oil filter is so you could not use an oil filter without a bypass. The oil filters with a bypass valve like the PF48 are metric thread.

You are not going to like my answer to that one.

Ever see a photo of the earth from the space station? Yea, there are no boundaries. Seems we in the US have this idea that those ''Unalienable Rights" GOD GIVES are only for US/Canadian citizens and only if they agree with us. There is a bigger picture...Acts 10 34,35 Read the entire account to get the context.

People say someone is taking their job then refuse to pick fruit/veggies or wash dishes or wait tables, clean toilets and change bedding in hospitality services. They see those jobs 'beneath' them. Then is when they beg someone to do those jobs. This line of demarcation is linked to a 'living wage'? Yes! But more so to a 'station of status'. Oh, we have a caste system here. We complain someone is taking a living wages job then wipe our feet on the backs of those who take the jobs we reject. Jobs by the way whose wages they LIVE on.

Anyway...... Peace to you and your house.

So you think it's OK for production workers in Mexico to be paid 1/10 the wages of employees in the US or Canada that are doing the identical work?

We were told in Oshawa during the early 2000s the plant's profit on each truck off the line was $5000. Not sure if that was in CDN or US dollars.

Maybe if GM dropped the prices of said vehicles due to the lower labour costs, some of the push back would be reduced. You don't know how many times I heard, 'If your wages were lower GM could lower the price of vehicles...'

Right.

As I mentioned earlier, the cost of living there is about 1/10th. When I lived in El Paso my $55K home was $5K in Jaurez. If I had kept my refining job in El Paso and lived in Jaurez I could have bought a mansion.

Now that tics people off but good. :crackup:

What I think is people treat other people poorly. Fairly isn't part of the human calculus. Ecclesiastes 8:9 is a summation from the wisest and richest King ever to live on earth.

We keep looking for a solution from the very ones causing the injury. Humans. All of us. We stink at self-rule.

This is meant as an example of my experience of union wages versus non union. Using me as an example of non union. My wage as a non union heavy equipment operator in 1973 was 5$ per hour. I fueled my equipment, checked the oil etc. My skills at the time was considered medium. I hadn’t reached finished grading yet. The job we were on had a section that was union. The operator made about double my pay. He had a supervisor, fueler, greaser that came with him. Costing the site owner much more. My salary afforded me enough to buy a home, car payment etc. With enough of those union type situations everything costs more because of the initial cost going in. That’s what happened to Detroit. Why there’s more plants in the south. Ultimately in the far south. Unions played an important role with labor no doubt. Then they jumped the shark. I know an ups driver making 150K a year to drive a little truck. His retirement will be the same pay. He won’t even be 60. He drives an 80K suburban, just bought a 5 bedroom house. That’s great everyone says. That’s exactly what drives cost for everyone. I grew up happily in a 1500 square foot house with one bathroom. That was middle class. Not anymore.

That's what I grew up in too. Bought my parents' house as I finished my apprenticeship when they retired. Nobody wants to start in a house that small any more.

Anyways, we're getting away from the intent the thread.
