I had the same problem with my 86.5 and I tore the whole motor down and rebuilt it all cost me like 1500 bucks for all the parts to my supprise that there was no problem with the crank it was still within limits by my handy shop manuel. So I did some checking and found a guy talking about the same thing and he said 7MGE motors are very intollerant of low oil even by the least bit. So this explains the oil pressure being right and the knock check the oil and make sure it is full. Mine does this also but has a leaking rear main seal so when it gets low it is a good tell all it is low. Also check for oil leaks you cant see like from the distributor oil seal with all the air intake stuff in the way it is hard to see if it is leaking thats where the leak on my 86.5 was baffled me never smelled the oil cooking funny I have had a 86.5 a 87 and a 84 only time I have seen that.
