I have an 82 GL Wagon 4X4 ans since I have owned it it has ran strong but the oil pressure drops to almost nothing when it is idiling for a minute, what could the problem be? Also the front end has started making a kinda rattling/cluncking noise when cruising between 1500-2000 RPM's (4th gear driving 35-40 MPH) my steering boot started leaking a while ago so i am going to replace it this weekend, could it possibly be the tie rod where it connects into the rack? or would it be in the CV axel / transmission connection?
