CRD and Sea Foam - any experience?
 
Hey. I'm relatively new to this CRD 3.0 and am wondering if anyone has any experiences to share regarding Sea Foam products. I've used them extensively on past four wheeler (like old Land Cruisers) with great results from the engine treatment and the transmission treatment.

Any insights into Sea Foam and our rigs? Really interested in the tranny additive results.

Thanks in advance.

I wouldnt add anything to the transmission in the Jeep, its all computer controlled and works quite well as is.

As far as a fuel treatment I'd look into Howe's Diesel Treatment if you're going to run anything.

seafoam advertises as being diesel compatible and I also have used it on my gasser with good results. in my gasser experience, seafoam works best when added directly to the intake manifold and then left to soak and then take your vehicle for a run. these crd diesels are much higher compression ratio and dumping into the intake make cause internal damage.
i did read a thread on the Sprinter owner forum about a guy that did an crd diesel intake cleaning with a solvent and then removed the glow plugs to allow the intake gunk to spray out, so as not to damage the engine. he said it worked well but I'd like to see the procedure and results myself before attempting it on my crd.

I would NOT put sea foam through the intake on a Diesel, it has been known to cause run away on some of the cummins trucks.

I would not trust many additives in the fuel and non in the oil on these engines because of ther design and the stringent requirements that MB put on the fluids.

I have run some AmsOil additive that is safe for ULSD fuel systems in my jeep but have not really noticed any change in performance or mileage.

Howe's as stated before is also good for ULSD and helps as an anti gel for the cold climates

your crd is designed to run perfectly well with the recommended gas and oil, nothing else

Thanks guys. I was just wondering. I've been getting some flairing from the motor when I first set off in the morning. I suspect its due to the tranny not shifting early enough. Once its all warmed up there are no problems.

are you letting the jeep warm up before hammering on it?

torquey 01-03-2013 11:09 AM

I am. I use the remote start and smoke a cigarette on the porch. Then when I get in and commence I really baby it trying to avoid the flairing. There isn't a lot of hammering going on especially not that early. 10-15 miles later on the freeway- yep. There's some hammering. I got the GDE tune.

When you day flaring what do you mean?

Re: CRD and Sea Foam - any experience?
 
As I approach what sounds like a good shift point, the transmission holds on to that same gear and the engine rpm's flair up. Like the clutch is slipping. Now that I'm thinking about it, it might be the torque convertor. All I know is that the sound from the engine jumps up an octave or so. Its a much higher pitched noise coming from the engine compartment. Once I get past first to second gear changes the road noise is too much that I can't hear if it happens in other gear changes.

there are some transmission TSB
Jeep Grand Cherokee WK - Technical Service Bulletins

including this one about water contamination

I recall a specific one for the CRD, I thought it had to do with reverse, but I cannot find it now.

I have used seafoam on my card. Bought it used with 50000 miles on it. I put a can in the in the fuel and a can in the oil. Didn't get any extra smoke but it did seem to run smother. I did an oil change 100 miles after putting the seafoam in. Definayely do not put seafoam into any vacuum hoses. Will cause major damage. I have also heard that there is a higher rpm gear change when it is cold out. Supposed to warm the engine up faster.
