That's too low. You mentioned a rebuild, so it is most likely too little torque on the crank pulley. The oil pump probably had just enough friction to drive it at first, but now the pulley is just spinning free from it. IIRC the torque is more like 250ft-lbs. I had to go back and retorque mine when I did a rebuild. Use a flywheel lock to do it right.

 

I don't know if it will cause the oil pressure to never register, but it will definitely cause a delay in oil pressure.

 

I'll check the torque again, I torqued it down to 210Nm last time but maybe my torque wrench isn't precise enough.

 

is it really a targa? or a convertable?

 

It's a targa, in Europe the 944 with sunroofs are called targa. I'll take some pictures in the future. First I've got to get the thing running. At the moment I'm regretting the fact I sold my perfectly running 924 and bought this piece of sh*t.

 

just curious.......why not go for the 951.....???

 

The 951, if I was a rich man....

The 951 is much more expensive in the Netherlands than the 944, they are much rarer to find so prices are easily twice as high as the 944. Also the 951 uses more petrol than the 944 and parts are more expensive. The price for petrol is 3 to 4 times higher in the Netherlands than in the US.

I don't need the extra power of the 951 although I like the front end better. That's why I'm very glad my 944 has a 951 front end. My car has everything I would like to have in the 944, power windows, power seats, sunroof, fuchs, sportseats, factory alarm and an under spoiler. The engine is rebuild, the interior is mint, and the car had a total respray, besides that I even like the colour. Yes life couldn't be better IF ONLY THE DAMN THING WOULD HAVE OIL PRESSURE!!

 

Socialist taxes on gas. All refineries pay the same for a barrel of oil. Costs basically the same to extract a gallon of gas. The rest is some profit and mostly taxes. Like the taxes here on cigarettes. The tobacco companies and retailers make a total of 60 cents a pack while the feds and states skim off over $2 per pack. Then the fed and states come out with their anti smoking adds. Hypocrisy! Note: I do not smoke. Never have.

Have you checked the oil pressure relief valve? Or replaced the oil filter with a MAHLE? Checked the wires to the oil pressure sender? Tightened the crank bolt?

Pull the plugs and the DME relay or the sensor connectors and crank it till you get pressure. Don't start it and run it to test.

 

Fan, with all the work you've done on the engine, I'd be inclinded to suspect the crackshaft pulley and/or the alignment of the oil cooler housing.

If the oprv is bound in the open position it will allow the oil to flow from the pump, directly back to the sump bypassing the cooler and the filter and all the oil galleys in the motor.

Pull the starter, install a flywheel lock, then from the front use a deep well 24 mm socket and a long *** breaker/cheater bar to torque that thing down, if you still dont have pressure, check and re align the oil cooler housing. Then check the oprv. Make sure the green o-ring is at the end.

 

Make sure the washer on the crank bolt is on in the right direction before torqueing further.

 

The washers concave side out?

I heard something about an oil gallery plug possible being blown out, does anyone have comment on that?

 

Hollow side goes towards the engine allows room for the Woodruff key. so that the pulley seats against the gear and the oil pump. If put on backwards no oil pressure and a damaged woodruff key and maybe pulley damage... hope that is not what happend.

 

210nm -= 154ft/lbs

I can't see how a simple oil and filter change can suddenly result in a complete loss of oil pressure.
I think there is something else here

Had you done any other work at all at the same time ? have you replaced anything else other than the filter ?
Did you use an engine flushing /cleaning oil or additive??? if so there is a very good chance you have loosened some sludge and blocked one or several of the oilways
Did you use any silicon based gasket cement?


I would probably check the filter first and make quite sure you have the correct part and it is properly fitted. If you had the relief valve out I would replace it with a new one.They are not expensive and it will eliminate that as a suspect.
I just can't believe that the pulley is suddenly going to lose torque and the pump fail because you changed the oil and filter.
