I am fully convinced that "other vehicles" exist to steal valuable time from our Isuzus (which steal valuable time from the rest of our lives). Back in April, we added a 3rd Subaru Forester to our "fleet" (1998, 2002, and now a 2006). I picked up this 2006 for 1500.00. It supposedly needed a CV axle, or 2, but I also suspected it of having a blown head gasket. I figured at that price, even if I had to put a JDM engine in it, I would still come out good (car had 194K miles, JDM engines are typically around 1K-1500 tops plus shipping). It did have a bad head gasket, but as a "Hail Mary" thing, I tried some blue devil head gasket sealer. The Blue Devil lasted about 1500 miles . I also found out that starting for 2006, JDM engines are 2000 and up, and hard to come by. I pulled the engine last Monday, and pulled each head during the week. Both heads were cracked. I took the heads to Clearwater Cylinder Head (yes, THAT one) and they assured me that they could repair them, and that they had good results with doing it. The heads are off, I decided to go ahead and check the rings. The cylinders were still showing good cross hatch marks. I pulled the pistons - the rods stay in the block. Ring gap checked out good, so I will clean everything up and re-install the pistons
First picture shows 2 holes at 10 and 2 o'clock to the crankshaft. This is where the front piston pins come out. I had to make a special puller to pull the front pins out. After pulling the wrist pins, you rotate the crank and it pushes the piston to near TDC. Then, I put a 5/8 deep socket through the pin hole on the rod and rolled it to push the piston completely out. After front pistons are out, there are 2 covers under the flywheel to remove the rear wrist pins. You use a long drift to push the rear pins out from the front (the front rods can be lifted to go under them). Outer wrist pin cli[s can be removed through access ports with long needle nose pliers. Wrist pins are full floating.
At this point, I have 3 of the pistons al ready to go back in. I'll prep the 4th tomorrow and get them put back in the block.
