Hola hombres,



I don't know how it happened but the oil pan on my '04 Titan has somehow developed a NASTY leak in it <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/102.gif' class='bbc_emoticon' alt=':smt102' /> At first, I thought that the leak was originating from the gasket but upon closer inspection of the pan I noticed a decent sized hole in the middle of the oil pan. If I wasn't so livid at the prospect of paying for a new oil pan then I would be able to appreciate the irony of a vehicle named after Greek mythological deities being phased by such a seemingly minor mechanical issue <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/104.gif' class='bbc_emoticon' alt=':smt104' />



Enough about that, let's get into the meat and potatoes of this DIY article. For those who are interested, this is the procedure for replacing the oil pan on a '04 Titan:



Note: Thankfully, I had the assistance of my neighbour, who is a very experienced mechanic, so he was able to provide not just his expertise for the job but also his engine hoist. If you do not own an engine hoist, there may be another way to access the oil pan but I just went along with what he did.



  1. Remove engine assembly.
  2. Remove lower oil pan, loosening bolts in reverse order shown in figure.
  3. Remove oil strainer from upper oil pan.
  4. Gently pry and remove upper oil pan from engine block. (refer to this Titan diagram if necessary: http://bit.ly/p1eKcX)

  1. Apply liquid gasket to upper oil pan mating surfaces.
  2. Install new O-rings to oil pump and front cover side.
  3. Tighten upper oil pan bolts in following numerical order:
    1. No. 15, 16
    2. No. 1, 3, 5, 7, 11, 13
    3. No. 2, 4, 6, 8, 10, 14
    4. No. 9, 12
  4. Install or connect the following:
    • Rear plate cover
    • Oil strainer to upper oil pan
    • Lower oil pan, tightening bolts in order shown in figure




That's the entire painful procedure my friends. I'm sure that there's probably a better way to perform this job but hopefully this write-up will assist someone out there who is just as pissed off as I was! <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/027.gif' class='bbc_emoticon' alt=':smt027' />

Nice how to. Was your hole in the lower pan or upper. Until your post I had no idea there were two. Hmmm
