I have a 98 eclipse with a rebuilt 95 4G63t with only 100 miles to date. i have been driving it like a baby for the past week. The other day i noticed that i had no oil pressure on my electronic oil read out, not even when i hit the gas. although engine does not over heat. the day i noticed the smoke i sputtered into shell gas to get gas. they were out of 93 so i put 89 in and bought stp octaine boost. shorty after the gas i noticed the smoke. what do you think it could be. The gas? or do i have bigger problems my oil is black only after 100 miles fully rebuilt motor? please help.

Your leak may not be coming from the outside. The AC has an evaporator tray that catches the humidity pulled from the air in the car drains it to the ground.. Sometimes the drain gets plugged up. Clear the drain and clean the tray. Sometimes that situation is accompanied by a nasty smell.
On petrol engines, the presence of black smoke from exhaust indicates that the air / fuel is not correct. If we check and find the spark plugs on them a layer of black smoke, so no air is uncertain.
The fix is very simple: replace the filter element from the air filter, clean or replace the spark plugs and, if necessary, adjust the air intake flap from. Black smoke usually disappears after the first fixes (replacing the air filter and clean or replace the spark plugs can be done even by the driver.
Sorry to inform you of the bad news but the white smoke is engine coolant burning off and the rough running condition is also associated with coolant leaking into the combustion chambers.This will be a head gasket repair, basically a head job where you will need to machine the heads down and install new gaskets from the heads up.Get back to me if you have any more questions, thanks and I hope I could help!!!
Lost of compression is due to either leaking head gasket, valves not closing and seal properly or piston rings are worn and need replacing. One can tell if you have bad head gasket, oils contaminated by water when looking at dip stick, bad valves cause some smoke and run rough, worn piston rings will cause lots of blow-by and will cause white smoke heavily and also runs rough. Being 1968 original motor and never have been rebuilt will probably have over 100k mile will be needing tear down and rebuilt. Rebuilt it correctly will get another 100k plus. being 1968, doing your head and valves job or replacing head gasket if that is the problems and you can get by it. worn rings, I would rebuilt it completely instead repairing one or two cylinder unless you plan to get rid of it.
This is caused when oil gets passed the rings n the pistons. Its due to wear and tear or old motor needs rebuilt. now you can put a bottle of motor honey in it. or some of that smoke be gone you find in wal-mart auto section of store this will greatly reduce your white smoke till you can get it rebuilt .
