I'm trying to track down an oil leak and suspect that it's coming from the banjo fitting at the side of the sump. My question is, do I need to remove the sump pan to reseal this banjo fitting or can I pull the fitting and reseal without having to remove the sump pan?

Also any suggestions as to what to use to improve the quality and leak tightness of the oil cooler lines? Currently I'm using high pressure fuel injection hose. Suggestions?

I also see that there are bypass kits available. If the oil cooler was originally there and you bypass it what do you do to replace the cooling of the oil crcuit?

Please comment on at least the banjo fitting question as I'd like to try and stop this oil leak. I've already change the oil pump, front and rear main seals, and seals around timming belt. But most of the oil seems to be coming front the oil cooler side of the mil.

Thanks in advance for the help. The mil has about 330K miles on it and runs strong (compression still in spec and within 3% cylinder to cylinder)
