Good night companions, I am a Spanish boy who I buy escort rst MK4 evo 2 and to taken 7 months to reconstruct its motor.

I feel if my English is terrible (my mechanics is better than the language jeje)
I have a problem that brings to me of head with the motor of the car, after to spend me 2000 euros (not what they are in pounds, pardon) and not to leave themselves him almost new except for some piece easy to change, I have the following problem:
When I take the motor in cold the car goes perfectly, but when it takes awhile started (on 5 min) it begins to ignite the light of the oil of the marker, and usually it is when the needle of the temperature of the water leaves the first square and it remains in the black zone.

Then I must accelerate until 1200 rpm so that extinguishes the light of the oil, it happens little other but of time and continues raising the temperature of the water and now one becomes to ignite the light again and I must return to accelerate until 1600-1800 rpm so that one becomes to extinguish.

And the other day I had to put it on the 2200 rpm so that one became to extinguish the light and the temperature of the water was already a little over the N of the marker, it lets accelerate from fear of which much was warmed up and breaks something of the motor and already extinguishes it.

The motor this even in running or nor that because by fear not yet it removes it to take a walk by this problem, the pump of the oil and the water is new, the thermostat and barilla that also holds it, the sensor of temperature and the one of the ventilator also are new, the filter of the oil is new and the oil is 15w40.

So that so much is warmed up?

So that it passes the one to me of the oil?

And so that it does not take the ventilator? (and I verify the thermostat and if that opens)

I feel to have written as much to tell to my good problem our problems, I have wanted to give the maximum possible data in order to solve my problem.

I like much this page although until today I have not registered myself, but I read what my head gives to translate.
I wait for your answers impatient and will take care of much to my small one.
Thank you very much and already I finish that I am a heavy one

Oranoco

Have changed the oil pressure switch?

When the light is on is the engine rough sounding?

Impreza

The sensor buys it new
Rough in which felt?
Something if they sound the hydraulic activators because it does not change
I want to put to him sensorial of oil pressure with clock but in Spain nobody has it here or not yet I gave with
Thanks to them for the aid

matt p

Think he oranoco means running rough mate,

Not sounding to healthy, not good to listen to

Impreza

Until they do not pass those 5 min the car goes perfect nor a complaint the problem is when happening that time
the sound I do not see him bad my seem what if I notice to him they are the hydraulic activators mainly to the slow motion

if u have rebuilt the engine then u are getting low oil pressure this means the crank shaft and bearings must be incorrect size!

u need to check engine again and measure the bearings and crank!!


also what oil are u using?

Impreza

if you talk about to lso large stone bench and connecting rod sockets they are new also, and the one that also moves the pistons (not as it is written in English sorry) they verified it

Impreza

I leave you see you tomorrow I must go to think things with the pillow. again thanks

Impreza

Today I went away to verify whatever took in igniting the light of the oil and to 4:50 min I start being on 1000 rpm and all this without moving nothing the needle of the temperature.
I put the revolutions to him to 1200 and thus I hold on 3 min and again to ignite and now was the needle in the first black piece.
It already leaves it and it extinguishes it so that did not suffer damages, I think to change to the oil and filter to him since surely they have dirt of the restoration of the motor
that oil done to him? 5w50 or 10w40
thanks

Impreza

nobody knows that it can be?

i have sent you a pm.

Hello. Your english is quite funny - but well done for trying

Did you have the crank reground and new bearings?

Impreza

Rick :
It cheers to me that it amuses my English jeje, but I am but of town that the flowers, the 2 games of sockets are new.

PeterRST
Thank you very much done an eye to him right now

davidreader5
Thank you very much, now I watch it

D.K.

sounds like me on the JD


no offence mate

Impreza

the circuit of oil thus goes (but it fails my memory) Coje the pump the oil and it sends it to the filter it fills it and it leaves to the T that goes the pressure sensor and to the metallic conduit that goes to the Garret and soon already the rest of things goes before the T of the sensor.
if the sockets were defective, the sensor iria well since a little goes later to the sockets that to the sensor.
P.D.:now already if which you finished laughing with my English and Rick jeje

Rick

You are right - it does go to the bearings after the sensor. But, it is the bearings, causing a restriction in flow, which cause the back pressure. A pump creates flow, not pressure. Without a restriction (the gap between bearings and journals) there is no pressure.

Impreza

and some form to watch if he is that without having to disassemble?
As it was the Web of burton is that no longer I decide to me and thus I watch if they have sensors for clock, because in Spain almost not ay nothing for these cars.
thanks companions

Rick

Im not sure I understand you. Do you want a gauge to measure the oil pressure?

1.9 xr2 on 40's

i have a brand new engine in my shed, it had the works execpt a oil pump, runs for a few mins then oil lamp comes on, taken it to bits shells are still fine as is the crank
but the pump is mangled inside, its gotta be same prob mate, stuff a new pump and a crank grind and shells if needed and you'd be back in action, ive had loads of oil pumps go lately, look inside and it'll be scored to hell mine all are

Impreza

my question was some form to watch the failure of the gauges without disassembling them. and as it is the Web of burton to watch sensors that here in Spain not ay almost salesmen for this car .
I am making a maximum force to include/understand your words but ay many words that I do not know that they mean.
it will make an effort to me still more, thanks.

Impreza

today it disassembles the low ones of the motor including the pump of the oil and I gave air him to pressure to the circuit of the oil and it was put to drip oil by the supports of the tree of pistons.
It can be that normal one or it is that positions can be bad?
also watches the old ones and I saw that habia of 0.4 and 0,5.

Greetings

where can i get one of them for my garden?!?

Impreza

that is my terrible English jeje, here in Spain cigüeńal is said but no matter how hard I look for to translate it does not give it with it so I imagine a little and I put the one of the tree of pistons jeje

Moonie

Usted necesita recordar que la bomba sólo crea el flujo del petróleo. Si los espacios libres de cojinete de manivela son demasiado grandes entonces el flujo del petróleo escapará al easilly que tiene como resultado la presión del aceite baja.

En el tubo de fonocaptor de petróleo hay agasket donde lo une a la bomba, la marca segura esto está bien. Si lo se dańa dibujará en aire que tiene como resultado la presión baja.

Impreza

Moonie your Spanish gives me to whom he is just as my English, we go but made an effort the possible thing.
Today I have bought a mechanical clock for the oil pressure and it will connect in the pump of the oil, me cost with connectors and tube 27 euros that to the change I suppose that sera something as well as 12-15 pounds no?
P.D.: somebody says the Web to me of burton to watch some piece.
Thanks.

HORNETS7

you are losing oil presure!!!

so it means that the crank bearings are either incorrect size or scored!

or your oil pump is not giving correct oil pressure feed!

PeterRST

But check that one-way flap on the oil cooler first, before you do anything expensive.

Impreza

today I put the clock mechanical to measure the oil pressure and the results are that 1000 3 returns when happening 2 or 3 min marks to means bar and raising 2000 returns bar marks on 1.5 bar.
So in short the only thing that coat in clear is that the sensorial affluent mark and that the oil problem continues being there and already single is left 2 things that can be no? Or sockets or the pump of the oil or happens something to you but
