[95cavspeed]

hey , i got a 1993 volvo 850 glt non turbo auto
now you guys will love this! it has 259kmi orig. miles!!! it runs/drives great minus a few probs

problem: rear bushings that bolt to body wore out so its clunking and then when i press down on the back it bounces and sounds like suntins broke more going towards the shocks or do these have rear struts?

problem: dash all works sept fuel gauge i was gonna replace the whole gauze assembley, but it could be the sending unit too i kno.

and last it has oil pressure in the crankcase / valve cover the oil cap is leaking so i guess i need to undo the black box and clean it all , is this an easy job\


ive been on this site like gonna be 3 years now, and thanks alottt!!! its the best one.
