1994 Mustang GT issues getting power back/Smoke
To start off this, we took the motor out and checked everything, took out the tranny as well. Right now the one issues we are having is smoke out of the dipstick.
- All cylinders were tested while cold/warm and tested out fantastic, so it can’t be rings.
- Timing is set to 14 degrees with cam. Have messed with it more but seems to idle and rev up fine where it is.
- The injectors looked loose in the holes, but lubed them and they went as far as they would.
- When put under load it will die, and won’t keep rpms.
- Oil pressure when cold works, when warmed up I have 0, unless revved above 1200 or so.
- Coolant seems to be not circulating when I got it, but think we fixed that issue.
Cant think of anything else. But need some help.. been sitting for 2 months trying to figure it all out.

When oil pressure drops to 0 at idle or after coming to a stop,with the engine at operating temp,its normally a sign your main and rod bearings are shot.If the engine begins making a knocking sound,when you come to a stop or at idle when the pressure drops to 0,thats a verification the bearings are shot.The crank and rods ride on a film of oil and once the bearings wear out,the clearance increases between these components and once the engine warms up,the oil gets thinner and this allows the rod to start rocking back and forth on the cranks rod journal.

I agree I had the same problem with mine a few years ago, the rod bearing got wiped out when I blew a head gasket from the coolant, you might be looking at a rebuild or a new engine
The only saving grace is that you can get 5 litres for next to nothing and they aren't all that hard to swap out.

If your bearings are that worn,ring seal could be bad too,causing stalling.A vacuum test with a gauge will further verify engine condition.
