A common problem when replacing an oil filter is that the o-ring from the old filter stuck to the block during removal and when the new filter is put on you have two o-rings stacked on top of each other. This will cause a leak. Take the filter off and make sure the old o-ring did not stick in place to the block.

Filter Replacement most vehicles

This is a tip for most vehicles so don't take notice of the BMW listing....this program made me choose...!
  • Whenever replacing any oil filter for any vehicle, check to make sure it fit's correctly.
  • Don't tighten at this stage
  • Once done, remove it and fill the filter with the same type of oil that's going into the engine....this will take a few minutes as the oil will take a little time to filter through the material inside the filter.
  • Once the level inside is almost to the top...(don't worry if it's a little over filled), wipe a little of the oil onto the rubber gasket seal and fit it, tightening following the instructioons on the filter.....
  • Clean off any spillage with a cloth.
  • This meathod reduce the time of low oil pressure in the oil galleries and reduce engine wear and concequently, saves you money in the long run....
  • The same meathod should be used when fitting a diesel fuel filter....It will reduce much of the pumping required for priming (bleeding) the filter. It will also reduce wear in the injector pump....(The injector pump is lubricated by the same fuel)....
  • If you have a problem priming the fuel line, and you have a vehicle with a priming plunger on top of the filter housing, remove the whole unit with the filter in place.
  • Loosen and remove the fixing nuts (usually two)
  • Lift the assembled unit and then lower it as much as possible leaving all pipes connected....
  • Holding the whole unit upside down or at an angle where the fuel will cover the valves inside, (about forty five degrees) ....pump the plunger on top....It will pressurise much more quickly....
Happy servicing

I want replaced diesel filter from dyna lorry

there are 2 types, one is just a cartridge just like a small oil filter, this one just unscrews like an oil filter, when you replace it there is a round knob that unscrews and becomes a pump, just pump it until it becomes firm then try starting it with your foot on accelerator until engine starts. The other has a filter with a bowl under it, they have a small bolt in the center top of the housing, undo the bolt and the filter will drop free of the housing. these have O rings top and bottom and a bleed nipple off center, loosen the bleed screw pump the pump until air stops coming out the bleed, close bleed nipple then follow the same start procedure. any fuel leaks will stop your engine from starting but do not over tighten either filter because they can be damaged

My 5.9 dodge cummins diesel won't start, I've replaced the fuel lift pump, and the fuel filter, turns over. But will not start?

Most likely you just have air in the lines.Crack them open one at a time and bleed them with the fuel pump off and on till you get fuel.If it fires dont hit the throttle let it sit and idle and close the line.Does it fire up with a small whif of starting fluid?

Disconnect the electrical connector for the "Water-In Fuel" sensor from the lower end of the filter housing. Then the filter assembly simply unscrews like an oil filter.After the fuel filter is off, you must unscrew the sensor from the lower end of the old filter and transfer it to the new filter. Then screw the new filter into place. There is a screw on the top of the filter housing to bleed the air from the fuel filter assembly. Loosen or remove the screw and pump the hand pum on top of the filter housing until fuel comes out the bleeder. Then tighten the bleeder and start the engine. If you did everything correctly, it should start right up and continue running. If it starts the dies in a couple of seconds, then you must perform the bleeding process again. (SEE PICTURES BELOW)

Hint: Sometimes it is much easier to get to the filter through the right wheel housing. It may be easier to support the vehicle and remove the right front tire to get to it.

1994 Jetta oil leak by filter, can the housing where the oill filter screws in get a crack or it just a seal that needs to be replace Thanks Jerry

I suspect that some how the spin on filter has been knocked loose and disturbed the integrity of the "O" Ring seal, or the spin on filter was put on wrong and pinched the "O" Ring seal. You will have to try a new filter and "O" Ring, which means draining the oil and replacing. When fitting a new "O" Ring to a new filter, be sure that the ring fits perfectly in the slot. Coat the "O" Ring with some vasoline to hold it n place. If the "O" Ring will not fit flat in the grove heat the "O" Ring in a pan of hot water for about two minutes. This will relax the ring and take out any folds.

Oil filter leaks around the housing no matter what oil filter is used or how tight it is on

Take the oil filter off. check to make sure you don't have 2 gaskets on there. Sometimes the old oil filter gasket sticks. This will cause a leak no matter how hard you tighten. When you remove the filter and hove only one rubber gasket, check it to make sure it was not pinched or scarred. then check the block for anything that might make a gap, or that the metal is not scarred or a crack. I would use a new filter to go back( that's just me). hope this helps

Looks like the oil is leaking out right above the

oil filter screws onto an adapter housing which also has the pressure sending unit on it (above oil filter). This adapter housing bolts to the block with 3 bolts. if oil appears to be leaking from where the adapter housing meets the block (especially at the rear side of engine near bottom), then you need to replace the siamese o-rings between the adapter housing and the block ($12 part at dealer). remove lowest 12mm bolt and loosen top 2 12 mm bolts(top 2 bolts won't come out unless you drop the engine down, but loosening 1 inch is all you need), replace o-rings and retighten bolts. be careful not to get dirt/grit between block and adapter. just finished doing this to son's 95 2.7 v6 which was leaving an 8" puddle of oil after idling for only 1 minute-worked perfect

Where is the fuel filter on a turbo desail

Your fuel filter is mounted on the rear of intake manifold, under air cleaner or on rear firewall.
Just a little hint on replacing it, remove your fuel tank cap to release pressure or vacuum in the tank. I'm sending you a diagram the fuel filter assembly so it will make it a little simpler for you to replace your fuel filter. Start by removing the filter element nut. Remove filter element by lifting straight out of filter housing. It is not necessary to drain fuel from filter housing when changing the filter element.
Installation, ensure mating surface between filter element assembly and filter housing is clean. Install new filter element by aligning widest key slot located under element assembly cap with widest key in filter housing assembly.
Tighten element nut by hand. Bleed air from fuel manager/filter assembly. Connect a hose to air bleed valve and place other end of hose in a container.
Disconnect fuel injection pump shutoff solenoid wire. Crank engine for 10 to 15 seconds. Allow starter to cool down for one minute between cranking intervals. Repeat procedure until clear fuel is observed at the air bleed hose.
Close air bleed. Connect injection pump shutoff solenoid wire and reinstall fuel filler cap. Start engine and allow to idle for five minutes. Check fuel manager/filter for leaks.9df1ca0.gif
