Low oil pressure at idle and Mivec mode not cutting in 4G92 MIVEC help!

[jay_lancer]

Hi I have a Lancer with a swap to a 4G92 MIVEC as per the picture:

Recently the oil pressure has started to go low when the engine is at idle/tickover.

This is shown on my oil pressure gauge as well as the oil light on the dashboard had been flickering.

Also the car won't go into MIVEC mode.

I have checked the oil, it is at the correct level on the dip stick and was only changed about 3000 KM ago, running 10W40 fully synthetic oil.

Everything was working fine previously, then after a long fast run on a clear motorway where I was able to go into MIVEC mode, when I turned off the motorway and stopped at some traffic lights noticed the low oil pressure at idle.

The oil pressure for regular driving looks fine.

Any idea's about to fix this issue?

Many thanks

hi jay, long time din hear from your project mivec..lol
i think you have your oil filter replaced too during servicing interval.
mivec not activate is part of protection.

Looks like need to change the oil pump. Better do fast as Oil starvation is not good for the engine

Oil pump problem like vr2turbo said. the oil press been that way since u noticed it?

Hi

Thanks for the reply's, have read that my engine can suffer from oil pickup in the sump getting blocked, will look into it, won't be driving it much until sorted out

cheers

Is your oil pressure level same as before? 1bar seems a bit weak but still fairly normal, if the pressure is the same as before, try check your mivec solenoid.

 

[lsm1991]

yeah 1 bar isnt horribly bad yet..... depending on the amount of wear, 1bar per 1k rpms can be considered 'sort of normal'

definitely a little lower because the alarm was activated, also oil light on the dash board came on.

Have been advised to try an oil change to 5W50 fully synthetic oil, will do that, and check the MIVEC solenoid.

Many thanks!

change oil pump..

new billet pump preferred...

 

[vr2turbo]

Since normal drive the pressure is normal, could it be the oil pressure sensor problem?

since oil pressure goes up with the rpm (till a certain point) si if it actually is starving, it will seem fine when you are giving it some revs. Afaik, it would only know if the pressure is fine or too low without taking into account the rpm speeds (on my old junk car at least, it isnt able to relate the rpm and oil pressure)
and since he has 2 sensors (one stock, providing ecu data hense the dash light and the other for the defi, which is also going off)

jay, dont think changing to heavier oil will solve anything, but instead only mask the issue if it works. (my 2 cents)

oil pressure need to check under load. free revs sometimes pressure is ok.

oh didnt know there would be any dif

**actually... am quite sure there will be no dif, oil pressure should (afaik-lah) be affected by the temps (affecting viscosity) and rpms.

I think I will try an oil and oil filter change, maybe just partly blocked oil filter?

does anyone know the best oil filter to buy for 4G92 MIVEC Gen 2?

If that doesn't work will have to look into changing the oil pump.

cheers

any filter will do really... am running proton filters on my car...

 

[parakey]

Is there any chance there's oil sludge in your engine?

Yup, my Mitsu VR also running Proton filters.....

The oil on the dipstick looks pretty clean but its possible, anyway hopefully an oil and oil filter change will help if this is the case.

It was a used engine so no idea how long it at been sitting before I bought it and installed it.

Anyway investigations have been on hold for the last few days as I have had food poisoning

slowly starting to feel better so will look to get the oil change done next week

cheers

take charcoal pills. Hope it help.
Drink more water.

Now is discussion to help car owner, then later back to owner's car......lol
