Your problem is not as descriptive as I would like to see and I have questions. You said that dexcool leaked. Did the raiator drain or leak in to the oil crankcase? Was there Dexcool coolant mixed with the oil? If there was, you could probably buy a junkyard 80,000 mile engine cheaper than fixing this one and have better confidence in it. If the coolant did not leak and flood your oil crankcase, there are other cheaper to fix possible causes for the knocking.[/Quote:f0e421f708]
The lower intake leak was very minor and no mixing of fluids had occured. I would add about a cup of antifreeze per week. Sometimes you could smell antifreeze when finished driving it but rarely saw drips because the leak was so minor. As of right now the oil pan is off and a couple of the rod bearings are shot, one being spun. Today im going to measure the rod journal to check for round or loss of material. If this rod is not reusable do you know if it is possible to remove the piston and rod with the engine in the van. Also do you have any suggestions why the oil pressure was lost to begin with? I dont want to go through all of this work and fire it up and not have pressure. I want to make sure im not overlooking some kind of internal pressure loss problem. Thanks in advance!
