- This video shows the process it took to replace the rear main seal of my 1999 Jeep Wrangler with a 4.0L and manual transmission. The exhaust pipe prevented the oil pan from sliding out so I had to disconnect the exhaust pipe from the header which allow enough movement in the exhaust to remove the oil plan.
The replacement parts used are
Fel-Pro BS 40612 rear main seal set
Fel-Pro OS 34308 R oil pan gasket
Scott, I just bought a 99 and it needs valve cover and RMS. This really did give me the information I needed. I feel confident doing the mechanical work, and based on your video it looks like it’s a small pain in a$$, but is do-able!! I just got nervous about getting that far into the engine, but your video showed me exactly what I needed! Thanks for taking the time and effort to record and post it!
Best step by step video yet
This gives me the Confidence to do this myself.
Well played.
Hey man....quick question. I just realized after installing my oil pan gasket on my 2000 TJ, I didn't push the oil pan gasket up into the grove in the back next to the rear main seal. Did I need to do that, or do you think the gasket seated properly when I tightened down the bolts? Make sense? Thanks for your time, and you did a great job with your video.
Doing this tomorrow! Well done!
This was very helpful 👍
Very good video - I assume everything sealed up OK?
There was some residual dripping the following week but everything sealed up and been working great for 6 months now.
About how long did it take you? Obviously you were recording video so that adds on time.
I probably spent 5 hours total over 2 days. I wasn’t in a rush and the exhaust disconnect/ reconnect added a lot of the time.
Whats the consequences of over torqued oil pan bolts
I would not imagine much if they are slightly over-torqued. The bolts need to be tight enough not to come loose. The oil pressure is low compared to cylinder pressure and torquing the head bolts.
Hey Scott, I recently bought a 1998 Jeep Wrangler. Doing more inspection on it I noticed that the skid plate was missing 3 bolts on one side but had all three in the driver side. So I was thinking how is it in place but I saw that they went ahead and weld it..... my issue is that I need to replace the rear main seal and the gasket in the oil pan. But I was wondering if I would need to remove the skid plate ?? Please help. And if I need to some how remove the muffler pipe ?
I didn't have to remove the skid plate. The transmission is mounted to the skid plate. When I added a 3 inch lift I also lower the transmissions by inserting spacers between the frame and the skid plate, so you may want to unweld the driver side at a later time. The exhaust header collects to a single pipe which runs to the catalytic converter. That is what gave me problems. The coupling is only 2 bolts 9/16 if I recall correctly. I did unhook the hanger for the muffler and tail pipe to allow for more movement. The hanger brackets are insert into rubber pieces. Hope this helps.
@@scottrogillio1436 thank you for taking your time and letting me know ! All these other videos I noticed they were removing the skid to get to real but I’m assuming since I have the original one there was no need for me to do that. But you went ahead and encouraged me this morning to get my project started ! And thankfully I was able to get that dam seal that was pretty challenging lol ! Now I’m on my way to buy the parts. I notice when I was removing the oil pan.. I literally put my ratchet and half a turn and they came lose .... from my understanding they supposed to be torque to a certain spec and also theres maybe 4 screws missing...
