ENGINE OIL OVERFILLING DANGEROUS???

[bullet]

hi! t'was my 1st time to do a DIY change oil on my 99 intercooler turbo starex. after having drained the old oil from the pan, changed the oil filter and air filter, i proceeded to fill the engine with fresh oil. after only filling about 4 liters (the manual says oil pan capacity alone is 4.9 liters), i checked the level with the dipstick and i was petrified that the level was about an inch above the full mark. what are the dangers, if any, of overfilling? i tried to dry up the pan by draining again the oil from the pan but the level is still above the full mark. lessons i've learned: not all of the old oil is drained when changing oil; and jack up the car when crawling underneath! your two cents worth please! thanks!

did you start the engine after refilling? did you change the oil filter?

if you changed the oil filter and did not start the engine before measuring the oil will go above the marker because some of the oil will still go to the filter. but if you did both and then there must be excess oil.

there will be too much pressure on the internals of the engine. most of the oil will probably go out of the breather. and the engine will sort of lose power.

it can either go into the firing chamber of your engine and burn together with the fuel thereby producing carbon.

or it can damage your fuel injection pump since it can mix with the fuel and create what we call a fuel dellusion. (tama kaya spelling ko?)

thanks ARB. I did start the engine (let it idle for about 5-7 minutes) after changing the oil filter before taking a look at the dipstick. So there really is no real potential damage to the engine esp. at high RPM's? by the way, it's auto tranny.

Thanks Doc Diesel! So how could I remove the excess oil? I've already emptied the oil pan...

check mo again overnight. get the dip stick, wipe it and stick it back. repeat again check mo three times to be sure. he he.

me i dont go above the full mark, sometimes a tad lower than it. IMO lang i dont know if more is better.

Was your engine oil warm/hot when you first drained it? Warm oil will drain faster than cold oil.

Was the car parked on a level area when you checked the oil level? You'll get a higher reading on the dipstick specially if it's parked on an up slope with the dipstick at the back of the engine.

jackaroo, t'was warm when first first drained it; and vehicle was on level surface.

OVERFILLING OIL IS A MAJOR NO NO!!!!!!!

Its better to have a little oil (Min level) than overfilling. As we know, oil pressure builds up as we increase revs. If you have to much oil, the pressure will build up excessively, thereby posing a serious threat to your oil seals!!! Although mura lang ang oil seals, ang hirap sobra palitan nyan!

You drain the excess oil through the same drain plug underneath. Be ready for some serious splashing! :D

In my diesel ride, i only put about 3/4 full (based on the dipstick).

You can avoid the splashing by opening up the crankcase cover just a little, enough to just let the oil drain through the plug slowly.

You can also remove excess oil through the oil dipstick holder, bili ka lng ng pinakamahaba na "feeding tube" usually 100 cms in length and french 8 yung caliber sa nearest drug store and using a 10 cc syringe, aspirate mo lng yung oil, mamemeasure mo pa kung ganung kadami natatanggal mo

Nice idea but with additional cost.

Nice idea but with additional cost.

done it already, mga less than 200 pesos ata expenses. Just do it pag malamig engine and konting tyaga sa initial na pagsipsip dahil matagal umakyat yng oil

[rmsoriano]

sorry, wrong post...

[jamesjames]

More than max level din yung sakin pag check ko sa umaga. So ganito ginawa ko (nakita ko lang din sa youtube saka sa suggestion ni butchyboy)

Dito ko nilagay yung excess oil, ginamitan ko ng syringe at feeding tube (125cm in length at french size 16).
Wala pang P80 nagastos ko. Available yan sa mercury drug. Kung meron pa sanang mas malaking syringe yun ang bibilhin ko kaso wala na ata.











accent hatchback nga pala yung sakin, but I think you can use the same feeding tube size.

ung isuzu pick-up ko lagi sobra sa langis..kumakain kasi ng langis un eh..so pagnagdadagdag ako..sumusobra naman..

kaya pag change oil sagot na ng mekaniko namin un.

bullet,
Hope this does not come across the wrong way, but are you sure you checked the correct dipstick- the engine oil dipstick and not the one for the auto tranny? I can't imagine draining the oil pan and still get a full reading on the dipstick.8O

overfilling oil is bad for the engine...the excess oil will surely destroy the gasketts under the engine..and it's bad for the crankshaft.

just my .02

Indeed it is harmful to the engine. My cousin over filled his L200 back in '96, without checking the level, he drove his truck, he heard gurgling noises, the engine sputtering then without warning, the truck revved so hard, thick, I mean really thick white smoke bellowed from the exhaust and the worse thing is the engine cannot be turned off! the traffic behind him cannot move on or overtake him because the smoke totally obscured their vision. It took about 3 minutes or so before a concerned motorist approached him and opened the air filter to choke the air intake with a cloth. The engine stopped but the damage has been done, piston rings and all. After the overhaul, he sold the pick-up.

After filling the recommended oil capacity in your sump you should start the engine to let some oil fill the newly installed oil filter then check for oil leaks as well. After shutting off the engine wait at least 15mins or better after an overnight parking, before checking the dipstick again. Remember to check the oil level while the car is parked on a level ground.

Overfilling your sump will cause the motor oil to foam and create to much pressure that oil will seek exit and ruin your crankshafts oil seals, gaskets, too much carbon buildup in the combustion chamber and other costly engine damage will result.

Its better to stick in between the maximum and the minimum mark of your dipstick! :D
