Bought a 2000 2wd 5speed pickup back in December with 81kmiles. Just noticed a slight oil leak coming out of the hole between the flywheel cover and trans after 2 thousand miles. The truck had Mobil 1 in it when I bought it and I changed it with Castrol conventional oil. I am assuming this is the Rear Main Seal (RMS) leaking and the only way to fix it is to remove trans, clutch, flywheel and replace it. Did a search and didnt see much on this subject. Someone has used BarsLeaks with success and others have changed from Synth to Conventional oil. I have already switched to conventional oil and dont like to add leak stopping stuff to the engine oil. I think my only option is to replace the RMS. Any other ideas?
