So my idiot friend both mis-interpreted my advice and is an idiot. He bought a 170K miles V70XC without records for "cheap". He then drove it to overheating and decided to make it to a "safe" exit (this in semi-rural Tennessee...all shoulders are safe) before stopping. Motor (per a professional shop that I am not 100% confident in) says 0 compression on all five cylinders, no steam cleaned spark plugs and timing belt intact and in time.
He decided he would rather follow with a refreshed motor by me than just do a head gasket and take his chances. I found a good donor that passed both my visual inspection and the carfax test. I got it out of the donor and into my truck after five hours (I hate pulling a motor solo) and in the process observed it was in time, PCV on both ports clean, cam cover free of oil, all five plugs identical and the intake and exhaust valves through the ports look good.
Car has 180K miles and is a 1999 V70XC that failed emission and got towed as abandoned (not hard in Chicago). It probably failed partially because 4 of five injector seals were totally toast. I am pulling it apart next weekend to do a head gasket preemptively and inspect the bearings. Outside of a catastrophic event, can I expect the same bearing longevity of the red blocks (virtually infinite) and the same with oil pump? Any need to replace a pickup tube o-ring, etc preemptively?
New timing set with idler, water pump and tensionor is a given. In the yard, could not break the flex-plate bolts free. Again, what are the odds the crank seal on that end needs replaced because I am guessing it will require heat to break them loose which guarantees the need to replace the seal if not that specific bearing.
Thanks,
Onkel Udo
