Evening all just purchased a tidy disco 2 TD5 with low miles. Went to change the oil and found one of the oil jet's when I drained the oil. In the process of taking the sump off now and I have now found what's left of a thrust washer... Question can I change the thrust washers in place or is it a lower end re build?. Funny thing is the engine was running smooth as with no noises or clatters.
