EJ25 cam swap question - swap cam or retain cam with head?
Posted 07 November 2011 - 03:16 AM
1. the replacement heads are off an engine with rod knock - which suggests previous overheating and these do sometimes seize cams.
- cam seizure is related to bearing surface on the head or cam?
2. the original engine has never been overheated.
is it better to:
1. swap the original cams into the replacement heads?
2. keep the cams married to the heads they're in?
done lots of EJ swaps, head jobs...but never thought about this...

This is a relief to anyone who has done millions of ea82's!
I doubt the cams would be affected as much from overheats, being they are farthest from the source of heat, and are made of harder metals.

And as pointed out are easy enough on a SOHC to change later if necessary.
Now if its ugly under that valve cover I might rethink it.

i'll probably keep them with the head, but save the original cams just in case.
