so i am getting ready to start the car and i just wanna prime the oiling system with oil before anything starts moving at any RPM! so i do so by unplugging the ignitor and fuel pump, turn it over for 5 seconds 3 times! oil pressure light dont go off! Now i do the routine checks and took off filter and oil feed line for turbo! turned over and no oil is coming out! bascilly what i am asking is have u been able to fix this problem by dumpng oil in the filter to prime the pump? i jut wanna know if some peeps have just had to prime the oil pump instead of getting a whole new pump!

and no one wask if the pan is dented cuz it is on good shape! and the pan was even off and everything looked fine!

thanks

Oil pressure light doesnt turn off until the car is running. When it is in on and ignition mode it stays on. It takes more than just 15 seconds to get oil flowing through the system.

oil pressure light turnos off after oil pressure has built up! i have done 3 swaps and this is the way i have done it! ther is no oil moving through the system at ALL! nothing coming out of turbo feed line nothing going into filer or anything coming into the head!

well i guess the oil ferry stole the 3.7 litres of oil i put in just before i turned it over? i am baffled as to why there is no vacum being made when motor is turned over! other then there could be buildup stuck in the pump itself?

No vac=bad compression. no plugs in it. etc

Please dont drive it or start it anymore!!....I had the same problem

your oilpan was most likely mashed in a little from the ride over on the pallet....

the oil pickup is only 1/8 of an inch away from the pickup,the slightest bit the oilpan is mashed your engine will get no oil....

pull off the oilpan......knock it out some....especially where the big square portion is out of all them little square shaped indentations right in the middle until it looks a little bit pregnant with a small piece of wood against the pan and a hammer...

dont bend the flanges and do not bang a screwdriver between the soft block and the pan.....carefully work it off by pulling on the lip of the pan around a little at a time until the old RTV breaks loose......

clean all of the old RTV off with a wire brush off of the bottom of the block and the pan...clean both mating surfaces with a generous amount of break cleaner so all oil residue is gone

for the install...run a 1/8 inch tall bead of GREY HIGH TEMPERATURE RTV in each one of those grooves you will see imbedded into the pan itself...run a very thin film of RTV around each hole so it seals around the holes.....do not get any into the holes of the block itself or you will risk breaking a bolt inside the hole because the rtv will not compress as you wonder why the bolt isnt seating in all of the way into the hole.....

not a very important part so you will not end up with any oil leaks....wait at least 2 hours before you add any oil to the engine so the RTV gets a chance to dry....if not the engine will get warm,vibrate and allow oil to seep past the RTV while it is still wet...

follow this and your engine low oil situation will most likely go away.....if not,think of it as preventive maintaining.

oh sorry i just ready your pan seemed to be good......lol sorry about that.......could it maybe be a stuck oil pump?........have you tried to pour oil into the oil passage into the block that goes to the turbo oil feed?......i heard thats a straight shot to the oil pump in that turbo oil feed hole there in the block.......I used a turkey baster with a piece of clear surgical tubing to put some oil in there and make sure at my startup.

hand crank the engine 15 or so times jsut to make sure there is no oil coming out. it takes a sec for it to actually start getting pushed through the whole system. and then if you still have nothing it would be time to check out the oil pump.

also, you did fill the filter with oil correct? and lub up the seal with oil correct?

yep i put oil in the filter pumped some down the holwe aswell! put oil in the turbo line on the block and also took off the pan and put oil in the actual pump from the bottom! nothing i have not actually started the motor just turned it over to get some oil pressure but i get nothing!

i am replacing the pump as we speak so hopefully thats it and the berrings are hopefully not toast!
