Does my 4200 inline 6 in my new Trailblazer have a ADBV built in like most modern GM motors? Reason I asked is I change the oil for the first time tonight at 1k miles. The stock AC Dolco PF61 DID NOT have a ADBV in it at all. None. The Napa Gold I changed it out with DID have one. Not that it needed it if the 4200 has one built in. This is a 7qt sump and I filled it with 5/30 M1SS. This motor is ice smooth man. Nice motor. Rev happy though. Which is fine. It recieved a firm but not abuseive break in Thanks for the input in advace on the built in ADBV question.

No engines have the ADBV built into the block, it's the bypass valve you're thinking about, as that is what is built into the block on GM engines.
YEa thats what I meant... Ok so it's bolted to the block... symantics

Hmmm...I think nomenclature...

BAh never mind I can see this is going nowhere... Delete thread.
Starbreaker, I think the 4200 does have the bypass built into the oil filter mount.
Purolator indicates no relief valve psi which probably indicates the filter has no bypass in it.

I think that the 06 are going to do away with this feature in the GM engines. I wonder why they waited so long
