Looking for insight on what to check. I have an excessive amount of fuel into my oil pan to the point it blows oil pan gaskets. 2002 2.3 with 160k miles. It can make it about 30 minutes on a fresh gasket and oil change before it pressurizes blows it out and dumps oil everywhere. I think this is to much fuel to be rings but I’ll start with compression test. What other things should I check? Injectors and fuel pressure regulator are what Google said but I want to ask people who actually have experience with this

 

Connect the dots. You suspect excessive fuel does what exactly to your oil pan gasket? You never mentioned measuring an increase in oil volume.

What was the reason you haven't mentioned the system intended to relieve crankcase pressure: Positive Crankcase Ventilation (PCV) Valve?

 

I figured it would be easy to follow the thread. It is dumping so much fuel into the oil pan it is filling the whole thing up and blowing out the seal and backing off the drain plug Within 1 day of driving after draining, new oil, and seal. The PCV valve was replaced already, at the time I made the original thread, and it’s still doing it

 

Based on what you have posted......

If this were my car, I would get a scan tool and see exactly what the MAP sensor and Coolant Temp Sensor readings are. To my knowledge, these values are what the engine computer uses to know how long to ground the fuel injectors.

Based on this info, you can go in various directions........If the sensor values looks OK. I would recheck for excessive blow-by by moving the oil cap. If all this checks out, for some reason the fuel injectors are either being told by the computer to be "open" or....."logically" they are stuck open and dumping fuel past the rings. When/If it is running, black smoke should be coming out the exhaust from so much fuel.

If all this and everything checks out......I can't see how else or otherwise fuel is getting into the oil pan......It is beyond my base of knowledge.

 

I’ll check those readings. It does have excessive blow by, even after replacing the pcv. So could be head gaskets. It spits out black from the exhaust and coveres the back bumper

 

UPDATE: pcv valve has been replaced. Compression was 150,170,170,170. Combustion leak detector test was done on coolant, does not leak any coolant, coolant temp gauge stays right where it needs to be does not get hot.

I will be brining injectors into a shop to have them test them, I hooked them up to a battery and they all clicked on and off, did not appear to be stuck open.

anything I am missing here on the fuel side of things? Anything else to check, possibly something to do with air? Any ideas feel free to comment.

 

It's not injectors. Compression on cylinder #1 is a little low and might be caused by a loose ring pack resulting in blow-by, which could be building up pressure in the crankcase. A properly working PCV system should handle that no problem. Has the oil leaked again after changing the PCV valve? Is the hose clear inside? And how are you making sure it is the oil pan gasket and not the other oil seals like a crank or balancer shaft?

 

I can see that being the reason for some blow by, the number is lower than the other cylinders but it isn’t low, I’d be more concerned if it was down to 100-120. It still does not work after replacing pcv. I can visually see oil leaking out of pan gasket on the car when I have it in the shop.

 

What did the spark plugs look like?
What is the O2 showing? Is it properly switching?

 

plugs appeared good, not flooded with fuel, car has light on for an 02 sensor, I bought one that I’ll be putting in soon.

 

If there is a cel for primary O2 it is probably busted and causing your rich condition.
Disconnect the O2 plug and see if the engine runs better, CEL will be on, but if the O2 is damaged it and runs better then it would be best to just run it in open loop rather than pig rich closed.
