I've heard of a good number of these cracked heads now. I sure hope this isn't a trend. I wonder if it's linked to the uneven head bolt pressure. I'll start a new thread... |

Mine isn't the head...it's the block that appears cracked. |

Bad part I still owe on it and gonne need to save mony to buy the parts  Oops, my bad Jrsavoie, I was asking the OP about his oil. Is that the Mobile one Turbo Diesel 5w-30? Mobil 1 td truck synthetic comes in 5w40, not 5w30. I think jrsavoie used a non synthetic amsoil, am I right? No. The Amsoil is a full synthetic 5w30 heavy duty diesel engine oil - I have used this in all of my GM 6.5 diesel engines since the 1990's http://www.amsoil.com/lit/databulletins/g1301.pdf I use Amsoil European formula that is recommended by Amsoil tech services for the 2006 Jeep Liberty CRD. They have both a 5w40 and 5w30 blend https://www.google.com/search?q=Amsoil+ ... 3&ie=UTF-8[/quote] Jrsavoie, you made my day, thanks for the link. I'll definitely look into getting it for winter. |

sorry been gone for awhile finally getting around to the tear down. and finally got enough money to buy the parts. Since I am close to 100K service I am also doing the timing belt, water pump, and glow plugs as well. to answer correctly a earlier statement and question. I use Mobile 1 5W-40 full syn. Diesel Truck oil. I got into the rockers tonight and found 3 rollers locked up. going to take the rocker cover into work tomorrow and clean it and I got all 16 new rockers soaking in oil right now. Why in the hell are the cam gears not keyed in. |

This thread got me thinking.... A few years ago I had my oil pressure light come on a couple times while at a stop light..., as soon as I pulled away it went out. I pulled over, checked oil and it was fine. I decided to change the oil and filter anyway and then if it reoccurred start trouble shooting the issue. The oil change and filter solved the issue. I assumed the oil filter I had been using was bad (pretty sure it was the old Motorcraft fl400 before they shortened it, I could use them on two of my vehicles so it was easy) and didn't give it much more thought. I have been using T6 oil for ages and mobil 0-40 prior (except first 15,000 miles when the dealer was putting 15-50 dino in as part of the free oil changes...I was less than impressed when I found out) Any possibility that the oil filters are playing a role in the rocker issues? If they aren't holding enough backpressure (or whatever it is called). I am handy and not afraid to take on many things mechanical but I am by not way even a decent shade tree mechanic, this is a WAG |
