Well this is going to be a long story and because English is not my primary language so I’ll make it as short and understandable as possible.
The problem is I have zero oil pressure.


The first thing that happened
1. My water pump broke down and got stuck messing everything up and it all got replaced.
new pump, new bearings and timing belt and everything that comes with that.
The timing belt got shifted when the water pump broke but it did not seem to have done any damage to the rest of the engine (push rods, intake and exhaust valves and etc.)
After it broke down the car was driven not more than 200 meters = 1/8 miles.

2. After that there was no oil pressure.

3. Got a replacement oil pump but after fitting that one still no oil pressure. When I say no pressure in mean Nothing at all there is no oil squirting out of any hole where it should when u have normal oil pressure.

4. Someone pointed out that the pump needs to be fitted with thick grease the first time u fitted the new oil pump. That is what we did and After fitting the pump we had 5BAR oil pressure that is what’s normal The car ran for about 15 minutes and the whole time we got oil pressure.

5. After shutting down the engine cool down and trying again later the whole pressure was gone. No pressure at all.
No when we gave it some revs, nothing.



What could be the problem here? No one knows anything because the oil pump (almost) never breaks down. So no one actually knows what to do when refitting an oil pump.

There is speculation by some mechanics from my garage that it maybe could be related to worn out main bearings, or the bearing from the crankshaft, or worn out bearings rot end bearings, camshaft bearing?
I’m no mechanic but I’m guessing its pure speculation because they have no other idea on how to fix this problem.



There are 2 notes that could be important:
1.1 When the car had oil pressure and ran for 15 minutes there came a lot of white smoke out of the exhaust and it smelled funny.
maybe an indication for a blown head gasket?
Could a blown out head gasket have anything to do with oil pressure?
1.2 When it ran with oil pressure (after fixing the water pump) the engine did not run as smooth like it should.
1.3 there is enough oil in the engine block.


Can anyone please give some suggestions.
