Keep engine smooth and rattle free at startup. If your engine rattles at startup it can be because your oil filter doesn't have an AntiDrainBackValve (ADBV). If you buy a cheap Fram oil filter you are doing more harm than good, even if you change your oil often. Check with your brands over there I know that PureOne or Wix/NAPA Gold have an ADBV valve. If your car rattle only at start up chances are if you use a filter with a ADBV it will be a memory! Hope that is helpful, peace Sammy

You guys are unbelievable! It is obvious from this post... http://www.mycarforum.com/forum/Aftermarke..._diff_P1399315/

 

..that many of you don't know that an oil filter can either keep oil in your engine if you have a AntiDrainBackValve (ADBV) or let it drain down into the pan without one. I could care less what brand you buy, just for those of you who want to keep oil in your engine, YOU HAVE TO HAVE AN OIL FILTER WITH A AntiDrainBackValve (ADBV).

 

I'm not sure what fixed this guys car but it is possible that he changed his oil filter to one that had a AntiDrainBackValve (ADBV). It is also possible it was the oil giving him temporary relief, but the "rattle" may come back. Advertisement? You guys are too much.

sounds good if it works.

 

on cold mornings the venerable 6 yr old goo will have a very coarse engine sound. tt my engine oil is 15W-60 probably doesn't help. after idling for abt half a min the engine sound back to normal.

 

so the oil will really not flow back to the sump with this valve? is it an entirely good thing? (maybe some stuff in the oil shd be allowed to settle on the sump or sth?

First of all, most of you probably arleady have the backup valve and don't even know it. Most OEM filters have a back drain valve, most cheap replacements like Fram do not or they dont work at all. They work, when the oil flows through the top of the filter it pushes the valve open, when the oil pump stops the valve shuts because there's no pressure leaving your oil in the filter and the engine. If you don't have a backup valve, the oil in the engine will just go through the filter into the oil pan. The valve looks like this, it's the silicone part. BTW, I prefer if you bro's don't buy this type filter if you think this is an ad.

alamak u just "condemned" "NAPA".shd have masked the brand.. hee hee.

 

i just changed oil n filter at my usual place. i saw the filter but i dunno if it has the valve. will remember to take a look at my next oil change, shun bian ask the mech if tt filter he use will keep the oil in the engine instead of flowing down.

 

but hey wait.. if the oil is in the engine then when u take dipstick reading after switching off engine and a few hours later it SHOULD be the same right? mine is quite different...(by electronic dipstick on dashboard). shd be accurate cos when i park on slope the reading changes too.

 

the reading is abt 4/5ths a short while after i stop the engine. it is full a few hours after i stop engine.

Dipstick is reading your oil pan level not your engine level. If yours is different it can be do to several conditions, cooling temp no backvalve letting oil to the pan, etc. Sounds like you don't have a backvalve bro, the oil is going from your motor into your pan. It is a very small level that will barely show up on a dipstick, but it is enough to cause you wear on your motor. You should do some research on good brands, because some of the cheap ones will not work as intended. Some of the good ones even keep the oil in the filter when you change your oil, so there's no mess. I could give recommendations, but after the reception I got from posting this informational thread, I'll pass. I don't need to get flamed which seams to be a pass time for some of you guys in SP. I leave it to the individual car owner to find out which are the best for you. I hope this is helpful to some of you guys, Peace Sammy

I think you got it wrong. Oil enters from all the small holes and exits from the big hole in the centre. this valve is to prevent oil and crud from flowing back out through the small oles. it doesnt stop oil from flowing back down into the sump. Think of it as a one way valve.

Then you definately have it wrong. Like i said, the oil flows through the smaller holes, the crud gets filtered out by the element and the clean oil flows out through the hole in the middle.

 

If you wish i removed my gauges the other day and still have the adaptor sandwich plate which i will take a pic of so i can show you how the oil flows.

The big hole in the middle is where you screw it on bro.

 

Which is more ideal? Get the mentioned oil filter or dilligently change the normal oil filter every 5K? I only keep my engine oil and oil filter for 5K.

I prefer it with the valve as there is less likelyhood of the stuff that was filtered out getting back into the engine, plus its abt $1 difference for a filter with the valve

You can change your oil every 500 miles but if you have a low quality AntiDrainBackValve (ADBV), then everytime you start your motor you will not have oil lubricating your parts until the oil pump pushes it back through the empty filter- and then until it fills and pushes into your oil system, or about 5 seconds or so. There are two functions of the AntiDrainBackValve, one is to ensure solids not to escape as someone already mentioned, the other it to keep the oil in the motor at startup. Every ADBV can perform the first function, only high quality ADBV's can perform the second. This is extremely important on any engine with a side mounted oil filter and especially 4 cylinder motors.
