1992 Evo with according to odometer about 16k miles. I have owned this since last summer and I have no information of maintenance history.
We are taking "upstairs" apart to change the seeping cylinder bottom gaskets. Will be doing valve lapping etc. while we are there as well as honing the cylinders for +.005" rings.
I have put maybe 1k miles on this and changed the oil twice to flush things. My oil has been Quaker State Mineral Racing 20W-50.
The cam chest wall has had a bump or crack as it has been welded and it's still a bit bent. Doesn't leak though.
The cam is original EPA/CAFE mandated N-grind which is severely choked on the exhaust side. Buddy has a practically unused pre-EPA L-grind which will go in. It should wake the engine while producing hefty low/mid rpm grunt.
