Finally got the motor pulled out on April 3rd and haven’t had the time to get it on an engine stand quite yet. But hopefully this weekend I can start wrenching on it again and start to see the failure point on this thing after taking it all apart.
It was an all day project but it was definitely a learning experience for me.

So I got to work in the car last Friday and was able to start the process of taking it down to the bare block. Something I noticed was that when I tried putting it to tdc the oil pump gear was a spline or two off. Didn’t get a picture but definitely thought it was odd.
I was able to get the head off the block and saw that my head gasket was covered in oil. I took a couple pictures of the inside of the block but this Friday I’m gonna take the rods out and inspect the bearings and hope there isn’t any terrible damage. And get myself some micrometers to start measuring my clearances and see what it needs when I take it to a machine shop soon.
Don’t know if the pistons are oem so any thoughts of the condition of the cylinder walls and pistons would be helpful!

So I was able to remove the pistons and found out that a piston ring in clylinder 1 made contact because it want gapped properly and cracked the piston and popped a piece of material off of it. It caused a ton of crankcase pressure which was eventually going to destroy all my seals and eventually the motor.
looking at the bearing material, crankshaft, and cylinder walls everything looked pretty good. I checked my crankshaft play to see if it was walking anytime soon and it was in spec.
I was also able to see that my valve stem seals are bad so that was a big cause of my oil burning issue.
I’m going to measure everything using my micrometers and dial bore gauge to make sure nothing is out of round and in tolerance. Hopwfully all the engine needs is a hone, and polish with the crankshaft. Still tons of measuring is needed ensure nothing is out of spec but everything is looking good so far.
