larry, the problem with the 2.7 is that the oil pickup and passages in the
cylinder heads are too small and it causes a large amount of sludge to
form, thus reducing the oil flow to the top end, and damaging timing chain
and valve train. as these are an interference engine, if the timing chain
breaks, pistons hit valves, and so on.. ive seen 2.7s with 40k miles on up
to 120k miles fail. it all depends on the maintenance of the vehicle. sorry
you feel that way about toyotas, but my truck with 200k miles and original
engine, etc, is much more impressive than my dodge intrepid 2.7 that
failed with 45k miles on it, and my dodge truck (used to have) that the
transmission failed at 70k, and both had had oil changes done every 4k
miles since new, trans fluid flush every 25k. it now has a 3.2 with almost
20k miles and is running perfectly.
