Hello again,
I got the timing chains, gears and the heads off tonight. Someone was inside this engine before me and I hope we never meet.
What would you do at this point if it was yours?
Where I am dong the work. I cannot complain...
The bent pliers and the hook made threading the cable ties around the idler sprocket pretty easy. I do not have that special tool for holding the chains on.
This pissed me off. This is the right hand cam where the sprocket mounts. Someone welded the dowel in position. The worst part is, he welded on the side which burned away some of the dowel so that it is a sloppy fit in the sprocket. If he welded closer to the bolt hole or even the outside edge, the diameter of the dowel could have been preserved for location/fit-up. ...some people. HO Cams anyone? :mullet:
The inside of the cam sprocket wa srelieved for the weld. AGAIN, the location of the weld was amateur. In addition to this, there was a bolt MISSING on the left side upper timing chain guide. $%^$%
Anyway, I got the heads off. They lifted easily. I did not know there was a ground to unhook and had to get that.
This is the left head from the bottom. You can see the area between cylinders #1 and #3. My guess is that they were sucking in some coolant. as well as leaking compression to coolant. I had suspected cylinder #1 as a culprit.
Looking down at the block after removing the head. You can see where coolant entered cylinders #1 and #3. You can make out the damage to the gasket too.
I will need to deglaze/hone (at a minimum) bores #1 and #3.
The left side headgasket, bottom side up. Again you can clearly see the damage between cylinders #1 and #3.
Next, I pulled off the right side head. This looks better than the other one, even with the carbon buildup.
This made me a bit mad. Looking down at cylinder #2 (on the right), you can see damage to the face of the piston where a valve struck it at some point before I owned it.
Here you can see both heads on the workbench. The cams are still in. I will break the heads down next.
So, it looks like I need to pull pistons #1 and #3 for sure and inspect and hone the bores (or more) I probably should pull #2 as well with the damaged piston.
... should I just draw up all 8 of them and inspect the works? I have the time.
What would you do at this point?
Thanks for looking. stay tuned for more...
I am going out to my little pub for a beer now.
