How would an oil filter cause an engine tick?

[SHOZ]

With the infamous Hyundai TSB about oil filters refusing to die, just what would be happening for a filter to cause a tick on start up?

I know there may be some filters that have drain back issues but if the filter is not at a 90* angle they will still have oil, maybe siphon out?

The Hyundai filter has a high bypass of 20lbs, most AF filters are less.

A torn filter would not impede the flow.

It can happen, anything from a clogged filter to insufficient flow that cuts off oil from the engine. If you use quality filters, it shouldn't be a problem, just stay away from the cheapy cheapy filters and your engine will never know the difference. I prefer to use OEM filters on everything because I know they work and were designed for my engine, never had an issue.

Flow through the media. Cool oil is many times thicker than oil at Op Temp, no matter what weight/grade you use. The media only has so much area and is a restriction. Hot oil passes much easier.

That's why I always recommend an oversized filter if you can find one the fits ... More media area, so it passes oil easier no matter the temp

But would not the pressure relief valve open? Especially with the low end filters having very low settings?

I thought from poking around on here that filters with poor or no anti-drainback valves were a common source of startup ticking...that parts of the engine could be oil starved from flow back through the filter after shutoff. I guess I could see cold oil and a faulty bypass valve also leading to ticking on startup, curious to see other thoughts on this topic.

Odd things can happen with a filled/clogged oil filter. I would replace as it's cheap and will cross one thing off your list.

This is more to find out why a filter would cause this. Especially seeing as the OE filter has the high bypass.

If it's just a short ticking upon start-up, I would say it's due to the filter and galleries draining out due to a leaky ADBV. Some engines are very sensitive to a leaky ADBV, and some engines aren't. If the engine ticks on start-up after an oil and filter change, then it's sensitive to the galleries and filter draining out due to a leaky ADBV.

If an engine ticks all the time, it's a mechanical issue and not necessarily oil system related. If it was related to the oiling system, then it's probably a weak oil pump or stuck open pump relief valve, not the oil filter unless it was totally clogged and cutting off most of the oil flow causing the pump to shunt most of the oil back to the sump.

Positive displacement oil pump - should still provide plenty of oil flow even with cold thick oil.

ADBV should only be a problem if the open end of the filter faces downward, but could be suspect. Some strange combination of oil galley design and capillary action and oil pump lash and parking on uneven ground allowing the oil to siphon back to the sump? Failed bypass in a cheapy filter(if there is no bypass built into the block)?
The tick should go away after a second or two with a positive displacement pump, but it shouldnt be there in the first place.

+1, but you're not supposed to ask that.

I've still not gotten a good answer on what the Hyundai oil filters have that other, non basement level, filters don't have.

All but the filtering specs are top notch. But Hyundai has not ever published them. An old Youtube from Australia Hyundai showed 99% of <50 micron first pass.

Hydrostatic principal would consider even a straight up filter as just part of the U-tube - If the side with the tallest column of fluid is not restrained - evacuation to point of equalization occurs.

A bad ADBV will at least cause all oil ABOVE the filter to drain down no matter what the filter orientation. Even if just the part of the oiling system above the filter drains down, it could cause start-up tick if the engine is super sensitive to any part of the oiling system draining down.

Okay, so Fram Ultra, Mobil 1 Extended Performance, TG, Wix XP are all more than adequate filters? Metal end caps and a Silicone ADBV aren't uncommon.

I have an engine tick (Hemi) but was able to get rid of it by running 5w20 Redline. Long story short, Purolator yellow was just fine but their synthetic blue filter brought back a tick on the same oil. Went to Royal Purple and again tick was gone. The tick on syn blue was minor compared to the one that Redline eliminated. But bottom line when you have a finicky engine, it reveals when you use a product that has weaknesses. Happy with the RP filters, have cut a few open and really satisfied they are high flow.

 

[Triple_Se7en]

Hard to find Royal Purple oil filters around the Detroit area. The high flow filters most discussed here are the K&N filters.

What's the criteria to categorize an oil filter as "high flow"? Especially when the oiling system is fed by a positive displacement oil pump.

High bypass psi?
