Hi all! First time post, forgive me if I do something out of the usual format.
About 4 weeks ago I scored my dream car, a 1990 760 Turbo Wagon. I got it cheap because the previous owner did not want to fix the "rear main seal" leak that his mechanic told him about. Turns out theres no real main seal leak but the oil separator was previously loved. By previously loved I mean slapped on with a healthy heaping of RTV and no o-ring. After using some elite detective skills I discovered that it was also broken in half. Cool! Easy fix right? Wrong.
Since replacing the separator and flame trap hose a few minor issues have shown up that makes me think I have a larger issue. Turbo Inlet hose (coming from air box ->turbo) tore at the pcv solenoid elbow thingy. Replaced. Drove for 2 days, lost power at 50 mph. It was good for about 2500 rpm or 40mph on a flat road, black smoke, would hear an air leak if I tried to go above that. Found hose from intercooler to throttle to be ripped. Creating a work around until part comes in.
Is this a case of 28 year old hoses being shocked by spirited driving (previous owner was 85, drove around town) or should I be looking for some other signs of poor crank case pressure? Or something else? May-hap a saboteur!
additional notes:
-engine running, oil cap off, oil spray/gargling went away after oil separator replaced.
-valve cover nuts were barely even hand tight, replaced valve cover gasket about 20 minutes ago to be safe
-inline fuel pump positive post legit just fell off when I made eye contact with it, shotty wiring. since rewired, ordered new cradle and pump. fuel filter has become one with banjo bolt on fuel rail side.
-nothing else seems to be disconnected, no damaged wires in engine bay.
-turbo looks suspiciously wet, cant confirm if PCV issue or seal issue.
Thanks for reading the wall of text.
