oil pressure - how much is yours running?

[Glanza_K31]

check the wire going to the standard oil pressure switch if thats rubbed through it could be earthing out that will course the oil light to come on, do your gauges all read good readings when the oil light flickers.

cheers for the reply mate, ive had a look at it all and the wires are protected (plastic tubing) the only thing is i have the t-piece just resting on top of my gearbox so may move a lil while driving. oil gauge occasionally does read fine when oil light flickers (can tell when reading properly, needle is nice a steady and moves smoothly with throttle)

try the things i mentioned the other night kei.

if still problamatic then start worrying, but i would change that sensor first.

were does the oil pressure regulator located? and what does it do to our engine? do we really need to replace it? what gains will we get it we change it? sori for a noob question (never encountered a situation like this)

thanks for replies

Hmm, interesting find Aga. :teach:

I shall have to get the pressure gauge I bought over a year ago fitted, see what sort of pressure The Bitch is running. She felt a bit sluggish when I drove her after the headgasket/timing belt was done, I'm wondering if the oil pressure has increased now the gasket isn't leaking like a seive.

Well gorgan and Dave..where i live conditions are much different..We are very far below sea level..when we have races here foreigners just "love" to remap their cars due to the conditions. Anyways everything doesn't always be universal..This is what we have done and found (the hard way too) when the spring isnt shimmed most of the 5e's dont last too long..98% damage comes from the con rod bearings and main bearings being starved of oil...

So we didn't just guess doing it but actually tried and tested via trial and error..

As Hardcoreep has the "1 off" Jam manifold i guess we too have the same issue lol...Or running in an engine hard vs. the take it easy way..

But there isnt anything to loose by adding a bit more tension, better to have a wee bit more oil pressure than a wee bit less..

but why would toyota have them the same? (im not doubting you as this is first i heard of this and u guys have the part numbers) 1 engine has a 7200rpm redline and a turbo while the other doesn't

Dave i know you're not a 5e fan at all and ive read somewhere here u said they dont last long..is it detonation or oil starvation issues?

Anyways after adding the washers (bear in mind its not like 100 washers but like 1-2 very thin ones) on WOT i get 75-79 psi

pics and guides will be usefull. will add a rep to those who will post the pics. thanks..

ok fastglanza....i now understand where u are coming from....and i now get that u mean in relation to your region/area..so all is cool buddy, just needed u to eloborate as to why u all did this....now i know

yeah...and i know its only about two washers used anyways....just to bump up the pressure a bit

question....which sump do u all use over there?--(4efte sump or 5e sump)

 

[Aga]

i don't think there's a danger of failure due to low presssure personally... around 4,5 bar is plenty of pressure (oem) and you're running 5bar...i'm running 5 bar too now on WOT (oil temps are 80 to 90 maximum though)

streching the spring and adding shims have the same result mate. but personally,the shim method is more accurate. but it needs just a very thin shim, cause a little goes a long way on oil pressure.

to install it you have to remove the oil pan, it's located near the oil pump, not a tough job, you dont need to remove stuff that's hard to install again...

 

[fastglanza]

Yes my Guru, Aga, i realized a while ago strectching and shimming = same resulting action.

Gorgan..we use the 4e sump (easy for oil drain) but i think we use the 5e oil pickup...im not 100% sure since we did this a long while ago and our garage is the only one with 5efte/5efhte reliability...but for sure it was a mix and match i think the 5e oil pickup goes deeper into the 4e sump so dat wud be a + for oil pick up...dread now u got I man 'I'tating pun dis but nuh fret im gonna give her a likkle peep Zeen ....I c d King David got yah Maloney boys badddd BULLET!!



lots of others seem to struggle..esp spinning conrod bearings etc

you don't have to be sarcastic man, i wasnt making fun of anyone...

humbleness great sign of knowledgeble teacher:teach:

no worries man u werent making fun..but i wasnt sarcastic

erm... hasnt anybody ever noticed that the 4efte & 5e oil pumps have a different flow rate? even the pressure values are different, in fact id bet my left nut that when using added washers on the oil spring youre doing it coz u leave the 5e pump...

we had come across this by co incidence, on several 5e's.. it does make sense really, an na doesnt need the same oil pressure as a turbo car..

What is the different between them? as i have a 5e one know and it seems the same as my old 4e one. Even the gears are the same as i tryed them.The only different that i can see is that my old one has on o-ring around the gears.

thats nothing bro, toyota had 2 versions of the pump.. one with & one without the o ring..

the difference between the 2 pumps is that the max the 5e pump can flow iirc was 20psi less than the 4efte one.. now im sure that means max flow, but it could also affect constant pressure i guess...

Sounds good info but how they can run different flows if their gear are the same and interchangeable?

 

[Aga]

the o ring just goes with what version of the block you have. older blocks have their own pump, the others with the o-ring, another pump. i dont think there's a flow difference.
