Magnum gurus: I have a 360/380 crate magnum and wondering if anyone knows if there is an anti drain back valve to the filter on these motors? Twice I've pulled the filter off and no oil drains out whatsoever ... thought that's kind of odd?
 
There is nothing added to the oiling system on those that I ever heard of. Was the engine cold at the time?
 
if there is an anti drain back valve, it would be in the actual filter itself
I bet a quick google search of the oil filter part number will tell you
 
The only way I've seen this on Magnum or LA motors, is when they've sat a few days. I deliberately let the car sit a couple days on my magnum powered Scamp(and previously owned LA powered cars) to do the oil change. That way when I remove the filter, it doesn't leak oil onto my headers.

Then save some oil to dump on your headers since the filter doesn't....

No kidding. :D
My Wix (Napa Gold) filters have the anti drainback silicone valve built into them, and I also have never seen anything in the block.
I have had that stuff all apart recently also.

Thanks for the feedback everyone ... yes, i'm not complaining about not having to clean up my headers! I did do this with the motor cold and sounds like this isn't too uncommon.

I removed the filter to inspect as I recently started the motor and had a lack of oil pressure momentarily upon startup. First time it happened and I started wondering if the antidrain on the filter had failed. That's why I decided to remove it. Then, when no oil leaked upon removing the filter, my mind started wondering if there wasn't some other anti drain valve or if I don't have another issue in the oiling system or a bigger problem internally. If no debris in the filter, gonna put the new one on and see what happens.
 
Do you use the 90 degree adapter? If not and your oil filter threads up to the block the oil will stay in the filter regardless since it points almost strait up. A momentary lack of oil pressure at start up is normal since there is no pressure built up to where the sensor is.

No, no adaptor ... and your point is exactly why I was concerned bc if there's oil in the filter and the galley from the filter to the block, and nothing has drained back, there should be almost immediate oil pressure (which is usually the case). What I also didn't describe during the questionable startup was a pronounced valve tap with the lack of oil pressure(which makes sense). So the question became, why no oil pressure for the few seconds which is out of the ordinary.

Since my post this morning, cut the filter up and was no metal shavings or specs or indication of a catastrophic issue and the drainback valve was intact so gonna try to self prime it and fire it up a couple times over the next few days and see what happens.
 
This is why I use an accusump. My car (and I suspect many others) can and often does sit for long periods. With the accusump, 80 lbs. of oil pressure dumps into the motor and pre-oils it quite nicely before start up.

I have had two magnum crate motors a 300 hp and a 380 hp both after sitting a couple days have some clatter when starting and quickly goes away. I was wondering if the right angle adapter worked on a magnum block.
 
Here's an oiling queation. Building my Magnum now. I had a new high volume Melling oil pump for my la. Will it work on my mag?
 
As previously stated, do not put a high volume oil pump on your engine! You dont need it for your level of build, it will only cause problems and suck HP

Already posted it up for sale. Gonna get a stocker. Would like to source a windage tray. Just bought a factory replacement LA style oil pan and pickup.
