Engine oil?

[taskidr8 Lurker Find all posts View Profile Close taskidr8]

Hi to all this is my first post here and I have an issue with oil/oil pressure my2006 grande purchased 3weeks ago 210kms been running well had bull bar fitted dual battery's,40mm lift,wired up fridge,lights etc and changed engine oil using 10w30.Just got the thing how I wanted headed away ova weekend towing my 16ft pop top towed there fine in 4th gear no issues what so Eva.On way home had been going for 30 mins in 5th was doing it easy as pulled ova at a tourist attraction and the oil pressure light flashed at me twice give it a slight rev and it went out so I checked level and it was fine (still about 5mm over full as per when was serviced) never thought much of it went in did our thing and came out started eng sounded fine no light so we continued on about 45mins later the light flickers again a few times and came on while driving along I figured it must have a dodgy sender so at the next safe place to stop I pulled ova and got out to check again (slight rev never made light go out like last time) I got out and it sounded like it had slight rattle in it so I shut it off while I pondered on the issue for 5 mins I rechecked oil etc all ok and thought I would start it again and see what happened as I figured the damage was already done it started and light went out as normal it made a slight rattle as it did and sounded normal again with no light on so I decided to continue on taking it easy towing in 4th again and doing 100kph at 2500rpm no more light and towed to home ok (80kms and about an hour further up the road) when we got home it sounded ok no rattles but a slight wine/wuring noise stoped engine and restarted normal again!!!
any suggestions/experiences ideas muchly appreciated please

10w30 might be a little thin with those Ks. Especially if the lobes are little worn in the oil pump then it may have trouble maintaining oil pressure when your rpms drop to idle and after a bit of a haul and upto operating temperature.

How was the previous servicing to it prior to you buying it ??? Sounds like the oil pump has either a fault as RanJ has said ?? Blocked oil filter ?? Or sump screen is blocked ?? Personally don't think it has anything to do with oil being to thin as my mate still runs 10w 30 and has well over 250 k on his... For it to be rattling it's not getting oil. I definately wouldn't be driving it any further till you fix it or you may be replacing the engine... Cheers Steve

Thanks for the replies Ranj & Steve will speak with toyota tomorrow and see if they have any ideas it's running perfict still and not making any noise at all so looks like its gunna cost$$$ to find out what it is not really what I want this early (I want my 80 back!!!) I'll post up results when they come to light cheers

It could be a sender issue, any decent mechanic or dealer will be able to fit a gauge and see if the pressure is ok or not.

How hard is it to change the oil pump on these? Is it timing belt driven?

So I decide to stop being lazy after tea and removed the sump after reading that these engines also suffer from the carbon/sludge problem on the oil pick up same as diesel the results would amaze u I'll try work out how to post pictures ASAP (dunno of there is a 5post rule here) the build up would have had the pick up 95% blocked and was unable to see through the pick up mesh the sump had half a cup of loose build up floating Around in it and all needs a good clean and reassemble in the morning I'll post up results and pics ASAP cheers Darren
Ps: any hints on posting a pic from my phone?

Definitely a petrol? The diesels have had issues with injectors seals leaking which led to the oil sump screen clogging up. Otherwise I would have to suggest a lack of maintenance. An oil flush will help clear out galleries that may have sludge in them.

Definitely lack of servicing I would say. I havnt read anywhere of the V6 clagging up unless it wasn't serviced. The diesel is a totally different kettle of fish. Do you have the full service history ??? OIl may be clean but also if not knowing the history it may have been changed the week you bought it to make it look clean to the buyer......As MJ said your are referring to the 4L V6 petrol motor ?? or have you posted in wrong section.??....Only problem with using those flushes is yes it will remove all the sludge and shit but will also dump it into the sump and possibly block the strainer again. It may be a process of flush, drop sump, flush drop sump etc including filter until its nice and clear...... Cheers Steve

Defently petrol and yes I am with you on the lack of Maintnece thing I would say changing oil brands (not knowing what was previously used in it)may have contributed to the loosening of build up in eng also I have done long runs in it since oil was changed not round town as previous owner (shopping trolly) there for a lot longer periods at full running temps and probbally the better quality oil I used cheers Darren

Yep, flush and dump and refill and dump and refill. Sorry about questioning the engine but it is easy to post in the wrong section and as Steve said not really anything reported about the petrol.

That's why I thought I would warn that it can happen lol not any thing I would wish upon anyone I'll be cleaning it all out tomorrow and refitting sump it's on my hoist so it's not a hard job to do every service or two!

Have to remember the oil galleries in these high tec motors (nearly all late model cars) and all the moving parts have such fine tolerances so any sludge may become lodged. I certainly wouldn't be leaving it long between flushes and cleaning the pick up and new filter. I would say your extremely lucky and havn't done any damage. The rattle was probably no worse then when you do an oil change and wait for that few seconds for the pump to fill the new oil filter up going by your description. I think your correct in saying putting new oil in then giving it some going away and at higher speeds has probably loosened it up which is a good thing or it may have got to the point of no return. Personally I would be changing and dumping every 500k or if there is any hint of that oil light flashing itself at you.....Just my personal opinion......Cheers Steve

Yes I am with u Steve I won't be leaving it very long at all and in the next 3000kms it will probbally get changed at least 3 times and the sump will come off the third time again for reinspection of sludge issue (unless light comes on again) then I will be upset lol as far as gallery's go the loose partials can't make it there unless they are smaller then the meshing on pick up the only real major issue with the unfiltered partials that do fit through is damage to the oil pump I will be checking oil pressure tomorrow with a master gauge and test running it with the gauge fitted to get an idea of pressures so at service time I can retest and compare to get an idea if it is happening again (hopefully not).I will report back tomorrow
