98 Pontiac Montana. The oil gets out through the oil filter gasket.?

98 Pontiac Montana. 5 seconds after I start the engine, the oil filter gasket blows and all the oil gets out.


I replaced the filter and I got the same problem.


It looks like the oil can not get up in the engine.


There is any valve witch is stuck? Or please tell me what may cause the problem.98 Pontiac Montana. The oil gets out through the oil filter gasket.?
Listen to BobWeb.........GM filter part number 25010792(PF47) with anti-drain back check valve.98 Pontiac Montana. The oil gets out through the oil filter gasket.?
A couple of things could be happening-





It is common for a do-it-yourselfer to not check the filter mounting surface of engine to see if the old gasket was left behind. If the old gasket is left in place when the new filter was installed, the old gasket will likely blow. Make sure the old gasket comes off with the old filter.





Did the new filter screw on easily? It's also easy to cross-thread the filter and cause it to not seal properly on the mounting surface. The threads on the engine are more durable, so if it did go on incorrectly, you may need to replace the filter.





Make sure that you put the filter on according to the directions - usually 3/4 turn after contact with the mounting surface.





Good luck
better run with the dodge man on this one Ive seen more than one tech buy an engine for this easy to make mistake
Remove the oil filter once again and make positively sure that the old oil filter gasket came off with the old filter. Reach up with your fingers to make sure the old gasket's not still stuck in place. Also, double check for the correct new oil filter part number and I recommend buying the OEM filter manufacturer's brand. Some engines may require the car manufacturer's specified oil filter to work correctly on your car.
Get a good light under the car. Take out the oil filter. Shine the light up where it goes. See that old gasket stuck on the part where it screws in? Get your scraper and remove every trace of that. Now get your rag and clean around that lip where you just took off the old gasket.





Now get a brand new filter. See the gasket there, already in place? Get a little oil on your finger and coat that gasket with oil. Now put it on, by hand. DO NOT PICK UP THAT WRENCH. Turn by hand until it touches the surface of the engine. Now turn it by hand 3/4 of a turn more.





Make sure there is oil in the engine, and start it. Check for leaks. If it is oozing, tighten it BY HAND a wee bit more.





Clean up your tools and put them away, wash your hands. Smile, you're done.
i own a repair shop,and the only time i have ever seen this happen is when the old gasket from the old filter didn't come off with the filter and this will cause it to leak like that, you can remove the filter again and check to see if there's an old gasket stuck on the housing,that's about the only thing other than it not being cleaned off real good that will cause this to happen,good luck with it i hope this help,s.
