There is only 1 cam seal to replace (passenger head). The other one has the cam sensor in it (rarely leaks) and if it does, replace the cam sensor. Takes 5-10 min if you've done it before. You are working blind but there is plenty of room to fit a ratchet.

Passenger side rear is where it's leaking from but will replace both, on the SOHC 98 engine the sensor is on the front of the cam shaft, see video http://www.youtube.com/watch?v=aJlVz9SawEE

I'll be so glad when I get rid of this nasty oil on the exhaust smell.

I'll be doing the same this Sunday, it doesn't seem very hard at all. I'm going to spray a ton of degreaser back there though, I can't stand the smell of burning oil every time I park and get out. I'll try to do a write up if I don't get too lazy.

I'm in the process of putting mine back together. I ended up putting an o ring on the drivers side rear with the cam sensor. Tightened it down really well, but I'm not gonna throw some codes due to the cam sensor am I? There seemed to be some sealant on it when I took it off the first time anyways.

I also have a quick question regarding these. I ordered new rear cam seals from rock auto. I was expecting them to be o-rings, but they are shaped like shallow cups. Is this correct? I haven't pulled the old ones out yet, but if they are correct, I will be doing them tonight. I can take pictures if it helps clarify.

They are O rings as seen in the video I posted above.

I believe you ordered the wrong ones as they should be o-rings as mentioned above. The rockauto "rear camshaft seal" description is a bit deceptive as it's for a different camshaft seal. You need the rear camshaft o-ring (thrust plate o-ring). The OEM part # should be MN176208 per the sticky at the top of this forum. Just a did a quick search for the OEM part # and ebay seems to be the cheapest after shipping. I'm going to order a pair and change them out for some cheap and easy preventative maintenance. Thanks for the heads up guys! :)

Does anyone have pics or a video of the rear cam seal for a 3rd gen with the 3.8? Also do you access the seal from underneath the truck or just reach behind the engine inbetween the firewall?

Sorry if these are dumb questions, ive never done this before but need to and I dont wanna pay the dealer a ton of $$$ to do it as it sounds relatively simple to achieve. .

Thanks everyone

Did you already check Google for images and video search?

Most everything I saw was for the sport. There was one thread on another forum for a 2002 ltd but everything was basically like reach behind the engine and feel around the cylinder head for the 2 12mm bolts.

that link should have a download of a 2003 fsm on it.
Not sure if that will help at all, but the 2003's have the 3.8 I believe.
