Mann W712/75 is made in Bosnia and has no ADBV. Is it safe to use in a 3800?

[slacktide_bitog]

I needed to replace the hood struts of a 2001 Firebird with the 3800, and I saw that the Mann W712/75 is listed for that car and shipped from the same warehouse as the Stabilus hood struts, so I ordered it. The filter did not result in any additional shipping cost over just the two lift supports.

Anyway, when I got the filter, I had to look at it and report my findings.

Date code is 2105, so May 2021. Mann only gives you the month it was made, not the day. It says Made in Bosnia and Herzegovina on the box, and just Made in BA on the filter itself.

Other than lacking the ADBV, it's a typical European Mann construction, Same 4 holes in the typical shape, smells the same as all Euro Mann spin-on oil filters, same round holes in the center tube.

My question is, is this filter with no ADBV safe to use in a 3800? The filter is mounted sideways.

How do you know it doesn't have that without cutting it open?

You can see the metal thru the holes in the base plate. The ADBV Mann uses in their filters is white. Other filter mfrs will be red if silicone, otherwise black.

All the 3800 engines this vintage I have installed filters on had an adbv, if it is absolutely necessary or not I don't know.

It looks like there's a Black ADBV to me

There is no ADBV behind the metal holes, I promise

The black you're seeing must be a shadow

When I look in the holes, I see the metal of the media cartridge

The old "smell test" ...

If the oil filter is mounted above the sump oil level, there is always the chance that the oil above the sump oil level can drain back down to the level of the oil in the sump if the filter doesn't have an ADBV.

I could be severely mistaken but I thought GM engines of yesteryear had an internal ADBV in the block and the specified oil filters did not have an ADBV in them .

According to the specs listed on RA’s site, that filter has an ADBV. Maybe you got a defective one?

I've owned 3 3800's and have used either Wix, Napa Gold or a TG Fram and all have ADBV's. These engines have a built in bypass. I wouldn't use it.

those GM engines have an internal bypass in the block, so the specified filters don't have a bypass, but do have an ADBV

Thanks, I knew it was something in the block .
