I'll Try to be short and to the point. Did research.. Read 500 posts on same topic.. "06 LJ / 4.0 / automatic... Just rebuilt engine/Rods,mains,RMS,rings,lifters,pushrods,rockers, all FelPro gaskets, honed cylinders, new oil pump, same crank and cam w/ 228K miles. time and money called for a budget build. Had the dreaded small drip at rear of pan. Did NOT use red anearobic sealant as suggest. 1st takedown I tried to add RTV under rear gasket on lip , major fail, it slipped out on install or something, oil poured out. Took pan down, removed rear cap, cleaned and dried EVERYTHING, Used correct sealant as per service manual. Red Anaerobic on bearing cap small bead on both sides where shown in manual. Ultra Black RTV in 4 corners sparingly (blue FelPro pan gasket). Hours and Hours of reading and youtube to make sure I was clearly understanding. Buttoned her back up (used recommended torque specs on all bolts 7 & 11 ftlbs) and still leaks. removed inspection plate to find drip (every 10 seconds approx.) coming off center of rear oil pan lip at idle and worse with throttle. Doesn't appear to be getting slung on flywheel like RMS leak (but I didn't drive it). Pan shows evidence of abuse (she's no street queen). Looks like the rear lip of pan has been massaged by someone, probably when I had trans rebuilt. So, 100% not rear of valve cover or sending unit or oil filter or any other common culprits. About to order the Spectra replacement oil pan and new RMS & gasket to take it apart for the 4th and hopefully last time. At rebuild I use the FelPro RMS, but noticed on amazon there is a DNJ brand and whatever the OEM sells at dealership.
Questions:
- Most seem to use Felpro , Is it the best or does anyone have opinion on other RMS brands? (im replacing while im in there to eliminate possibility that I damaged seal)
- I bought the loctite red anaerobic gasket sealant #51817 and waited about 30 hrs before I put oil in and started. Is that the right stuff?
- I've seen many use additional RTV , glues, Offsetting the 2 piece RMS, ETC... , I chose to stick to the books and failed. thoughts on other than spec methods?
- I need the technique with the george foreman guaranty not to leak (for a while anyway) so I can finish getting this thing to reliable daily status again. Trying to not have to buy a vehicle by investing some $$$ in my jeep.
