Engine coming apart?
I am trying to help my friend, his high mileage GTU has lost oil pressure and feels like it is running on one rotor. When he accelerated a bit to clear it up, it blew white smoke. It is hard to start, and has never been overheated. He also said he heard a loud metallic sound in the engine.
I'm thinking it needs to be overhauled (DUH). Plan on helping him do a compression test tomorrow night, will post the #s. Basically my question is:
What would make a motor lose oil pressure and possibly compression at the same time?

If the oil drops pressure it doesnt take but a minute to loose compression.... The oil between the seals and housing actual acts like a seal itself. Thats why if you have a flooded motor you shoot ATF or oil in it to reseal everything. Thats if nothing is scared already...

Most of the time, "lost oil pressure" is just "bad oil pressure sender". If not then it will be something obvious like a broken oil cooler line.
It's hard to say what the issue is since the descriptions of the problems are poor.
Only running on one rotor could be many things besides compression. Bad injector (which would make sense considering the smoke), bad plug, bad wire, etc.

Mine eats plugs like 12 year olds snort pixie sticks....
Might want to give the regular tune up a try and see what happens. Hey, it needs to be done non the less right?
