Default Gasket leaks from hell...........

So, I decided to tackle an oil pan gasket leak. It was leaking from the front driver side corner, bottom front where the oil pan and timing cover meet and a small bit from the back.

So I take off the pass. side motor mount, starter and jack up the motor enough to clean up the oil pan and mating surface. Put new gasket on and rtv (orange high temp) the corners. Fire it up the next day and it leaks just as much from all the same spots

Let the motor cool and redid everything again, this time I sealed the corners, front and rear with "the right stuff". Fired it up and it leaks just in the front but worse than before. In about 20 mins of idle it left two fist size puddles.

One puddle formulated below where the accessory component bracket meets with the block on the passenger side. The other from the corner driver side of the pan again. ( I don't think it's coming from the intake manifold I know that can be one of the places that leak).

I'm thinking about taking everything off the front of the motor and replacing the timing cover gasket and any other seals that are in front (might need some insight into this). Also, going to buy a new oem oil pan and replace the gasket again. The car is nearly perfect all but this dang leak and I just want the car to be done without the leaks. The motor only has 16k ish on it and runs great, I don't want to have to clean up oil every time I drive it.

What gaskets should I replace on the front besides the timing cover?
Any other insights?
Thanks

fel pro gaskets have never let me down. when you take everything off the front pull the timing chain cover and see if theres a crack or something on the bottom causing your leak

Sounds like you tore something somewhere along the line. I would remove the oil pan and timing cover and reinstall new gaskets. If everything is clean and dry like it should be, no RTV should be necessary.

Remember, timing cover goes on first, then oil pan.

Thanks for the advice (timing cover then oil pan) glad this isn't my first rodeo or I might have missed that

I think I might just go with a new oil pan and gasket and see how that goes. I'm guessing the oil pan is warped from previously being over tightened. Both leaks are in the front and one of them clearly from the driver side front corner.
