Hello all, not my brightest day today, my beautiful 740 of 10 yars started smoking today on the highway. I stopped at the next exit and had her towed, here is what I found...I lost all coolant and oil, I replaced both and started her after turing over maybe five cranks, coolant came out the bottom of the water pump and some oil trickled out of the top end behind the top timing gear, the rear timing belt cover literally melted to the block and partially melted the top and lower front covers. I want to fix her, she has every bit of 280k but ran strong all the way until today. I did not find any antifreeze in the oil, would this mean that I did not blow the head gasket? Is there an oil seal behind the timing gear that may have blown? I know there was an oil leak at the right front corner of the valve cover that was increasing for the past 7 months. In regards to replacing the rear timing belt cover; any advice on how to get the top and bottom timing gears off and successfully back on without messing up the timing? I removed the water pump and got a new one, I pulled a top timing belt cover from the JY and now need the bottom and rear ones. Any advice would be appreciated and if anyone has the lower and rear covers, I would be interested!
Thanks so much, Noel Smith Morrow, Ohio
