Wasn't happy with the last responses so i thought i would post again. Is my Mech right in saying that fixing the oil leaks in my 94 mitsubishi would only cause leaks elsewhere due to preasure caused by a worn engine? eg ..it would (oil) find somewhere else to come out??

probably. sounds like he may be trying to save you money, best to put that money twords a new or rebuilt engine and the swap, if it's not a major leak.

Pressure can build up in the crankcase if the piston rings are worn and the Positive Crankcase Ventilation (PCV) emissions system can't keep the pressure normal. Then oil could be forced out the crankshaft oil seals. I've never had that problem on any cars I owned since PCV systems were introduced, but I've never had an engine that had worn piston rings since then either. If your engine is burning a quart of oil every 200 or 300 miles, then you may have bad piston rings in addition to bad valve seals and need a new engine. Burning one quart of oil per 800 miles is considered acceptable in even a new engine.

Older cars just burn oil. It is a fact. But, here is how you find out for yourself if your car is leaking or burning it. Take a big piece of cardboard and put it under your car and let it sit there overnight or for a few hours during the day. You will see the oil drips if something is leaking oil. When you start the car (if it isn't cold where you live), is there a puff of white smoke that comes out of the muffler? This is something that you will see from the driver's seat. If this is the case, your car is burning the oil. Not much you can do about it. Replace the car if you are that concerned about it.

Possibly. The bottom line is I would not put very much money into a 94 Mitsu. Mitsubishi really does not make a very good car, I'm sorry to say. Get what you can out of the car without spending much money and then scrap it for something else.

if the pcv system is pluged he is right it will build up preasure an find a weak spot an start leeking. oil preasure drops as a engine wears and high millage an lack of service ie oil changes

Possible, where is the leak from?
You may just want to change out the gaskets just to be sure it wont...
If your engine is so "worn", you might be better off having it rebuilt...
If it's broke, fix it...i don't think it'll be any worse than the leak it currenlty has...sorry i went all over the place with this answer-lol
Best wishes

No, he is being an ahole telling you that, a leak is a leak, not necessarily by pressure..... more than likey from worn and craked rubber gaskets and seals. Take your car to a REAL mechanic.
