| Does anyone in the forum know what the maximum allowable exhaust gas temperature is for the engine in the CRD. I am looking to update the exhaust system in my Liberty and have gotten hold of the mathematics to calculate the correct pipe diameter. | |

Replying to: lightnin3 (Aug 22, 2008 5:24 am) What your technician told you about running a few miles on the highway produces the same remedy as the "nose blowing" of the EGR valve. This trick was found by Renault 'Road Angels' many years ago. They could get the cars going again without opening the engine compartment; I still do it for my catalyser once a week, preferably at night.  I have close to 85,000 miles with no issue apart from the battery. I observed that when the battery was getting problematic, the free spinning pulley of the alternator was constantly dirty. This can explain that  Since then I have a new truck again. The BFG T/A tires have 56,000 miles and still 1/4" of rubber on them. They are getting slippery on wet pavement now but have been a wonderful deal since day one!

Replying to: caribou1 (Aug 22, 2008 11:09 pm) I use your "nose blowing" trick on my CRD several times per week. I get some smoke initially but then it clears up after repeating it a second time. On a recent long trip, I performed the nose blowing a few times. No smoke/soot after the second treatment. I have been using Amsoil cetane improver and Amsoil detergent additives pretty regularly and they seem to help. I wish U.S. diesel fuel had better quality and had higher cetane. I will be replacing the hose from the CAC to the engine in the next week or so as part of it has oil soak through. I am looking to get a custom built silicone hose, with a drain to replace the existing one. Changing it is tiresome. |

I was cleaning out my Liberty yesterday. When took the top engine cover off (the one that has "2.8 CRD") I found for the 2nd time that either some field mice or some other small critters not only made a nest under the cover but also chewed the loom and insulation off of 3 wires for the injectors.  I covered them quickly with eletrical tape, but I'l have to either re-splice them with weatherproof butt connectors or just use heat shrink tubing to re-insulate the wires to keep them from shorting and catching on fire. I kept the cover off thinking that this will discourage a repeat visit from these unwelcome tennants because it will hold the engine heat and it makes it an excellent place for them to nest in. Anyone else have some ideas/thoughts on this?

| Same thing happened to me with my 05 CRD this last winter. The mice made a nest under the engine cover, using a bunch of foam insulation they tore off the underside of the cover. I repaired the bare wires with liquid insulation by starbright. I have used it for permantly insulating and sealing out moisture on jobs like trailer lite wiring, boat wiring, etc. Rodents seem to like chewing on wire insulation and they did a good job of it on the wiring for the 2 middle cylinders. Most auto parts stores and hardware stores carry it. More permanent, seals tight, and easier to apply (has a brush on the cap). | |

Replying to: lightnin3 (Aug 22, 2008 5:24 am) All you have to do is unplug the maf sensor or install a Serg and install a Provent to stop the oil from the turbo to the FCV, and about the fuel? do not ever use Shell fuel, go to any other station that you see truckers stopping and use that fuel. If you like to see your engine to smooth out you can use TCW-3 oil at 2 ounces per gallon of fuel and that will make a lot of change in your engine. I buy my at wally world (Super Tech).
