    Re: WJ 4.7 engine failure

    Geno, Sorry to hear about your jeep. I have never heard of any major problems with a 4.7. Maybe the previous owner did not maintain this engine properly??? I had my VW for 3 days and blew a turbo.....$2K..Pervious owner used wrong oil......

    Dodge/Chrysler 4.7
    TSB #1802901 -- SOME VEHICLES MAY EXHIBIT A CONDITION WHERE IN THE OIL PRESSURE GAUGE INTERMITTENTLY DROPS TO ZERO. *TT (NHTSA ID #629157, DECEMBER 28 2001)

    TSB #01025 -- SOME VEHICLES EQUIPPED WITH 4.7L OR 5.9L ENGINES MAY EXHIBIT A CONDITION IN WHICH THE OIL PRESSURE GAUGE MAY INTERMITTENTLY DROP TO ZERO. *TT (NHTSA ID #628203, NOVEMBER 07 2001)

    Hmm, think there may be a problem there?

    So, has any-one used the local place, All About Engines for a rebuilt engine? I could get one for 1,500 with a 1 year warrenty. Please let me know.

    SAD, SAD, SAD

    The previous owner claimed he did good maintenace, who knows.

    For the 60,000 miles Shauna & I put on it, we changed the oil every 3,000 miles. Looks like that was $$$$ down the drain.

    Re: WJ 4.7 engine failure

    If you have had the vehicle for 60k miles I don't think the sludge has been there that long or the damage would have occurred sooner.

    Is there just sludge in there or grime too that might point to dirt getting in?

    Have you lost any coolant?

    Sometimes failures in the PCV valve can have negative effects on the oil too.

    Man that just sux

    I'll look into that.
    BUT
    With all the research I did, I still belive there is a VERY STRONG CHANCE that the oiling system has a major flaw in the design. Just way to much pointing at this engine with all the consumer complaints and the TSB's.

    I'm still looking for the "five credible sources" that say that the oil ports on these engines are at an angle which causes the ports to clog and cause extreme amounts of sludge.

    Re: WJ 4.7 engine failure

    I'm not too familiar with this motor but there have been other motors that HAVE had that problem for sure. I think one was the 2.7 L. Passages too small and hard angles causing fluid friction. If all other causes are eliminated, that just might be part of it.

    Do you keep all your oil receipts? Maybe contact the oil manufacturer and let them know what is going on.

    Your correct, I seen alot of bad reports on the 2.7l as well.
    Also
    I found a few different Class Action Law Suites against Chrysler for sludge/warrenty related isseues.

    Receipts? naw, I buy in bulk since all my XJ's and the WJ use the same filter. I dont keep the receipts, and I dont use the dealer, jiffy lube, walmart or any of thoese places, so no record there.

    I still need to come up with a future protection plan, maybe an addative like seafoam or something I hate adding anything to the oil, I just prefer to do my oil changes at 3k, but you seen where that got me.
