I changed the oil to 40 weight and there is good pressure. At idle, is another story - zilch to maybe a flicker and the needle moves a hair.
I opened up the bypass valve to check it out. No news.
Where is the oil pressure sender for the 84?? I dont see it on the oil filter housing (not a spin on oil filter) and I see no part listed for it. I see no reference to the 84 sender in the Service Manaul CD or the Haynes. Why?? Does the oil go by tube right up to the guage like my old TR-6? Also no, mention of the sender on the wiring schematic.
84 190E 2.3
