To be able to take correct measurements, I had do clean it up a little.
This is how the cylinder head looks before assessing what to do.
ANY THOUGHTS?
Advice, ideas AND suggestions are very much appreciated.
I think these `macro` pictures are showing a condition that`s probably and hopefully not as bad in real life as they seem here. It is the camera that kind of exaggerates damages such as pitting, scratches, crack width etc.
Yes, the head doesnt look too great and it has cracks.
Those cracks are located between the intake and exhaust valves, probably the widest gap is at the front, cyl#1. I would estimate it to be 1mm but not sure. The tip of an exacto knife blade fits in it just a little
but that is not some good comparison or a scientifically accurate measurement.
Now that the surfaces are somewhat cleaner than when the head came off, time to take some time to measure warpage.
This engine was sending gases into coolant and I saw it too when I got it started after some sitting... a possible overheat event is unknown, I`d put my bets on a YES.
What is it that these pictures can already tell you?
(and what`s the max warpage that you`d allow?-- in case this head checks out as a worthwile candidate for a revival attempt. should the greenbook be followed? they would junk any head over a 0.5mm gap I think. maybe 1mm, I cant remember. )
