Some of you may know that I buggered up my heads on my /4 a few months ago. I put in a step-down stud on the exhaust and put it in crooked. I pulled the heads, sent them to the machine shop to have them fixed up.
In the process of pulling the heads, one of the cylinders stuck onto the head. In pulling it off, I broke one of the rings on the piston. Lovely! So I then pulled all of the cylinders, and honed them to break the glaze. I just bought a new set of rings, and will re-ring all of the cylinders. I will be putting new rings on the pistons this weekend and possibly installing the cylinders. I bought a ring compressor too. The pistons, rods and crank all stayed in the case, except for one piston I took off for measurements, etc... I will be putting that back on too. This is the first time I am doing this. What oil should I use for assembly? Since the pistons are already on the rods, I will be slipping the cylinders down onto the pistons. Any hints there on how best to handle that? All of the push rods, rockers, etc.. were marked for their cylinder, and will be going back where they were. Is there anything else I should be looking for, doing, etc..??? Oh, what's the torque setting on the nuts that hold the heads on? Is there a preferred pattern for tightening those? TIA |

Steve,
Not sure I follow your method on measuring the correct height. I understand what the measurement is for, I just don't know how to determine the correct thickness of those shims. The cylinders have shims already. Can I add another shim to make up for the removed material or do I just get a single thicker shim? I spent about an hour last night cleaning the pistons. I will see how they look this morning and go from there. My goal has been to do as little disassembly as possible. The plan being that I would have less to do when I put it all back together. It's not working out that way. LOL. |
