Hey guys, need some input on this one.
Been fighting with Napa a little on this one, pushing it up to Wix.
I've been running the 1311's on my 1990 Volvo 740, a now gone 96 Volvo 850R, and a 91 Dodge Ramcharger 5.9. The 1311's are spec'd for the 850 and the engine now in the 1990 (strange, Wix shows a different filter but the OEM didn't change). The Dodge shows a different filter, same design, just lesser filtration and lower bypass pressure.
So...the issue:
I've run the 1311's for several years, never an issue, until the redesign. The previous ones (white cans) were solid. Put the black ones on the 1990 and 1991, both started having delays at EVERY startup before building pressure, 3-4 seconds on the Volvo, 5-6 on the Dodge. After about 500 miles the Dodge started getting what I thought was a sticky lifter. Ran some crankcase cleaner (1/2 can of Seafoam, 60 miles of light driving, drained, new filter and oil), noise didn't change. Swapped the cam after finding what appeared to be a failing lobe, new lifters, no change in the noise. When that filter was removed following the breakin on the cam, got minimal drainback from the block, odd for this vehicle. New filter, fresh fill of M1 10w40HM (standard fill for the rig for many years), about another 700 miles in the oil pressure started dropping. Still having the delay on building pressure. Ordered up a set of mains and rods, new pump, and thought to just try a different filter.
Installed an M1-204, the delay is gone completely. Cracked it loose, started puking oil as it always used to do (all over the driveline). Pulled the pan, mains were good, rods were down to the copper. Rolled the new shells in, reassembled, fresh fill of M1. Oil pressure has returned, builds pressure by the time the engine has lit off after 4 rev's., even if it's sat for 3-4 days.
Swapped the filter on the Volvo last night, went from 3-4 seconds to build pressure to having 45psi by the time the engine lights off after 4 rev's.
Talked to a friend, has a 94 Volvo 940, runs the 1311's the last couple times, has a noisy bottom end now, didn't have it 6 months ago as well, OP light takes a few seconds to go out now, didn't do that beginning of the year, and he's on top of maintenance as well as I am.
So, the common element here, the new version of 1311's.
Right from the get-go I can see there's no longer a support spring behind the ADBV, where the previous white ones did have it. The 1307's have it (spec for the 1990 Volvo's original engine), the 1085's (spec for the Dodge) have it. I can easily push a screwdriver past the ADBV into the filter cavity on the new ones, can't do it without puncturing the ADBV on the old version.
Anybody on here run into this since the redesign after the Mann buyout?
Any thoughts on the scenario?
Napa will buy back the filters, but it would be nice if they'd cover the cost of the bearings at least. My bigger concern though is keeping others from having engine damage due to lack of pressure buildup.
I'll stick with the M1 204's since they are spec'd for my entire fleet at this point.
Sorry for the mini novel. lol
