If I were an oil leak... where would I be?, sub question: does how you delete emssions cause a problem? Options

[qatar11]

Say you rebuilt your 5SFE from the ground up.... and say... you have the kind of oil leak that would require approx 1 quart of oil to be added every hour (Endurance racing conditions).. Where would this leak be coming from?

- *Every* seal on the engine is new (inc. valve guides)
- Most of the mess is on the transmission side of the engine / engine compartment
- Removing the access plate? the back of the flywheel looks dry / I don't think it is the rear main seal

Other interesting tidbits:

- The PCV has been deleted and replaced with a little cone filter... should this be replaced with a catch can?
- The EGR has been deleted and a large bolt has been used to block the port... has anyone deleted EGR and if so how did you do it?

Is anyone running a proper oil pressure gauge? What are you getting? @ High RPM and high load and when we are full and cold - we are high (60-70 psi) As we warm up, it drops to 50 psi or so... and then we lose oil until things get very low... 40 psi or so.

Welcome to the club. I'm about to get a new oil pan. I've taken mine off and put it back on twice already. The first time I did the "4mm" bead recommended amount by the books. It leaked in that same spot.

I then did a bead that was like 3 times as thick. It's leaking again. I'm about to just grab some grey permatex stuff and smear it across the surface, or get a new oil pan.

P.S. I used this type of pry tool

The flat side is thinner, and you can make it fit between the mating surfaces, and then just slide it across to break up the silicone a bit.
