Help! oil Pressure light remains on!!!

[miked]

Ako naman ngayon ang nagkaproblema. My engine is 4D56T..kahapon lang e nagfflicker ung oil pressure light. kapag nirebolusyon e nawawala at kapag hindi inapakan ang accel pedal e nago-"on" ung warning light ng oil pressure. nangyari na ito dati last june 2009 i think but due to low oil levels.
Pero ngayon iba naman. ok naman ang oil level. i'm using delo gold 15W-30.
Last oct 2009 eto mga pinagawa ko:
1. change cyl head gasket
2. change valve seal
3. cyl head grinding
4. change oil and filter

Eto naman ang mga iniisip ko na checkpoints:
1. sending unit baka defective
2. due to oil leaks sa oil cooler lines (bka humihigop hangin kasi matagal ko nang hindi napagawa ung kaunting leaks)
3. worn engine bearings (crank and cam)
4. plugged oil filter? ewan ko lang kasi may bypass naman.
5. plugged oil filter? ewan ko rin.

Sa mga nakaexperience nito kindly share naman. it would be a great help at least i have some ideas bago ko ipaconfine ang pipip ko. thanks a lot mga sir!

nga pala, maidagdag lang. may leak na rin front oil seal ng crankshaft

the oil pressure light (the one after the handbrake ((0)) light) remains on for like 5-10 seconds and then disappears.
this is normal. The reason why it's lit remains on for 5-10 sec. &then disappear, the oil in your vehicle has not yet attained the required pressure to open the oil pressure switch. Now if the oil pressure light will not disappear, kindly check 1. Oil level 2. Oil pressure switch(N.C. position).
3. if numbers 1 & 2 are OK your vehicle might have a problem in the oil pump.

imho, medyo matagal ata kung 5-10 seconds ah. should be max 2 seconds. kung hindi tumataas ang oil agad baka masira ang engine kung aabutin ng 10 seconds.

yup, medyo nag bago na sya ngayon mag mula nung napilatan yung front oil seal. pag start mga 1 second nalang bago mawala minsan sabay na sila dun sa check light at charge light. next oil change ko will be * 229,333km nagyon eh 228,089kms na sya so i still have 1,244kms to run before the next change oil. hehehe!

normally dapat ganyan. once it happens again, check mo din baka overdue na din yung oil change mo.

naalala ko ganyan yung s3 ko before, yun pala nakalimutan ko magpa change oil, so malabnaw na yung oil, hindi na nakakaakyat.

Yep, I'll make sure to check if it's due for oil change.

Thanks!

I'll post any developments.

had it before, in my 1973 ford escort. worn crankshaft bearings. worst nightmare scenario. it was cured after the overhaul..

* kurby: most prob it's the oil pressure sending unit. malapit na ma-busted. or it may also be the oil pump... i also recommend that you use semi-synthetic motor oil. NEVER use oil additives. it doesn't have any use. sayang lang pera mo.

i suspect i have the same problem with boss kurby. naliligo na nga yung timing belt B ng makina ko. bumigay na rin front oil seal kaya nagfflicker yung oil pressure light on low revs. on high revs kasi nagooff

[kurby]

With front oil seal removed:



Yan po ang nangyari sa makina ko...
