Low Pressure D Eclipse

good who could help me with my problem .. I have an eclipse GS 1992 Motor 4G63 was bn with oil 20-50 .. a mechanic I recommend the use of 25-60 xq the high temperatures that are here .. The oil was very thick .. ps changed it again by 20-50 but follow the fault .. in cold it rises but when the pressure is heated, the pressure to the normal minimum level .. who knew of a fault the same. Will the pump be forced damage x 25-60? XFAVOR HELP .. I would like to know what tests do to rule out or know if it is the bomb

Hi Alexandroq28.
I do not know the 25-60xq and had no news of him, but you say you used the 20-50 again and the problem persisted, you may have wear in bench caps or the pump derivation valve broke down with the oil you used. Multigrado oil has a low viscosity at room temperature, which allows more ease of pumping inside the engine and by increasing the working temperature degrades much less than the monographer, so I do not think your problem is the oil. Luck.

Thank you friend .. if here the Shell Halix 25-60 is sold .. In Concluction Debria Anilla and change the shells to the benches and connecting rods D Un Vz? (Make the engine) This derivation valve is where the signal signer D is from oil?

Hi Alexandroq28.
The derivation valve is the same pressure regulatory valve and goes to the outlet of the lubricant pump or in the same pump body, before doing something, the compression to the engine to verify status of the rings, if the regulatory valve is well inspected a preferable bench cap the closest to the steering wheel and one of connecting rod. In bench the lower cap shows the wear and in connecting the superior. Luck.
