Isuzu Rodeo oil pump

If you tell me the exact type of the engine I can try to tell you something more detailed on the subject.
Have you tested to place a Manometro clock to measure the real pressure of the circuit?
When you say that you have made a complete over -over machine change I understand that you mean a engine repair (cylinders, pistons, crankshaft casqillos etc ..)
I imagine that for this you have taken the engine, I would look that they were connected correctly the manocontact connectors, because sometimes they resemble those of other nearby connectors and it is easy to make mistakes, and it would be made to make the pressure. electric failures; If with the clock the pressure does not rise, then you will have to check the pump and the pressure relief valve of the circuit (for which you have no choice but to remove the carter from the engine) which is a work of the fuck with the engine placed in the vehicle;



Ah, another thing, some of those models, not necessarily to yours, they used to break the pump of the pump (the pump that looks like a mushroom) and when they accelerate lost pressure, look at it too

If my dear friend changed all this cylinders, pistons, crankshaft casqillos, they gave me the car and everything perfect. For six months and then I started this light. But I already checked an electromechanical and all good. The problem is not electronic. If a clock was put, this brand good pressure during the ignition, but 3 minutes later the pressure falls very for the required levels. My concern is that this bomb is only 6 months old. Thanks friend for all that desire to help. We continue learning.

Mira Quisas is a medium silly question, but you have checked the level and nominal value to the oil?, if the answer is if, then you will have no choice but to remove the oil pump and change it, unless the sucking is obstructed. Anyway you will have to disarm for Chekar.

Yes, I already prepared to take the car to a mechanic to make the pump change. The oil that is already using the age of the car is 20W 50. Greetings and very pleased by all the aid. Edwin

Hello,

I just read the post and I have been fully reflected. I have a 1.7 Diesel Corsa of 98 and it has happened to me exactly the same as you.
I have changed the manometro, the filter, measured the pressure in Relay and finally consulted with a recommended mechanic.

Just today, I talked to him and as soon as he told him the symptoms and the car in question, without blinking he has told me after seeing the engine that the problem is the oil pump.

He has also told me that the ISUZU motor model that uses the Corsa has given oil pump problems and that its repair for the position it occupies is very difficult.

Come on, a thousand and peak euros. He has also told me that with low oil 5- something. Right now I don't remember something, that the car was going better. That if you previously have to clean the engine with a cleaning liquid for these cases and that apparently sold in car stores or I imagine, maybe in TB gas stations.

Tomorrow I will do it, to see what is the result.

What a chasco, a thousand and peak breakdown I am not going to pay that I have it clear. Let's see how much it lasts before bursting. hahaha
