Hi all. Got a serious problem with my CRD. It's complicated by the fact that this all happened close to a month ago, the day before I left for my honeymoon in South America. I just got back last night and am hoping I can get my Jeep back in running order. I know it's serious, but I don't know what it is. Here's what happened (hopefully my memory is sufficiently in tact):
I was cruising down the highway at about 60 when I started to hear a loud whining sound. My first impression was that it was something to do with the A/C system, so I shut that off, but there was no change. I started losing a lot of power, so I pulled over and shut it down. I wouldn't say it was missing a cylinder because it wasn't jerky at all; it just lacked power. I opened up the hood and did a visual inspection. I wasn't sure what to look for, but I didn't see any obvious damage, hoses blown off, etc.
I gave it several minutes to cool off and started it up again. No problems doing so, but the whine was still there. My next thought was something to do with the turbo. I wish I had thought to make a recording of the sound, but I really didn't want to run engine longer than needed. The sound increased in pitch significantly with an increase in throttle. I drove a little further and got it off the highway. It was barely able to propel itself and it started smoking
a lot - to the point that it could have been on fire for all I knew, except that it was white smoke, no black smoke. It smelled somewhat sweet, maybe plastic-y.
I wasn't about to run it any further, so I shut it down right there. A passerby stopped when he saw all the smoke. We pulled the dipstick and there were some metal specks in the oil. A friend helped tow it the short distance home and then a tow truck brought it to a local shop the next day before I left town. I didn't have time to find an experienced CRD mechanic, so it was brought to a shop where my friend has had work down on his Dodge Cummins diesels.
So the shop has had it for the last few weeks while I've been out of the country. They say it's definitely injectors and that everything else (compression, glow plugs, computer) looks fine. He ran some "BG244k" through to try and clean them, but he says the problem is electrical. He says the #3 and #4 injectors are failing electrically and are dumping way too much fuel in. He says the #2 injector is running at about 80% and the #1 is perfect. He recommends replacing all four at once. He spoke with the dealer and they want just under $1,000 each for new injectors.
A couple other notes: The mechanic says the motor sounds good and that he didn't find any metal in the oil - and that a certain small amount shouldn't be a concern if I had found some.
1. Does his assessment line up with the symptoms I described?
2. Anyone have a recommended source for four new or rebuilt injectors that aren't $1k a piece?
3. Anything he should be aware of when replacing them?
a. I've read several other injector posts and it sounds like the copper washers need to be thoroughly
cleaned for a good seal - Will new injectors come with new washers?
b. It also sounds like new injectors will require a computer tune to fine-tune their settings. Who
does that? How much $ am I looking at for that?
c. Anything else?
Other info:
2005
About 110k miles
New timing belt at ~102k or 104k
No other issues besides the recent installation of an inline thermostat
Thanks for the advice.
My baby left me when I got married, but I want her back and I'm confident we can all live together peacefully.
