Change d rings, pumps, gaskets, guides, metals, pistons, seals and seals, I am in Los Angeles California where we are average 70 to 80 fahrenheit, the oil I put the high mileage, the thickest there was
I put castrol oil 10 -40 for vehicles with high mileage which is the one that normally put
The oil is perfect. What pumps were changed, the oil? Sounds like there is an obstruction in the oil veins. When it is cold, the density is higher, but when it warms up a little, the pressure increases and the viscosity drops. The same goes for the oil, being new. Was the filter changed when the oil was changed? What compression does the truck have?
Oil pump, water and every oil change I change the compression filter I need to check well with my mechanic who was the one who helped me check and tells me that it is fine, thank you very much for the prompt response
Sorry, I thought I understood the last message. Is the compression ok? The values as soon as they are ?. (It is important to know their value individually.)
Not bad, I would only recommend Liqui Moly Engine Flush, or one of the Liqui Moly line, after using it, the oil and filter must be changed again. However, I reiterate, the pressure drop is due to obstruction in some line. I discard the pump as it tells me that it is new (so I also rule out the sucker (the one that sends the oil from the crankcase to the top).
