Thanks to many of you who posted all manner of good tips on this. I've had the o ring and crank pulley seal on hand for over a year but was dreading the job because so many had to drill out those pesky oil pump cover screws. Today was the day.
So I thought I had the screws handled with a new 90 degree Lithium Ion impact screw extracter. Uh, nope. Total fail. It didn't get any of them out. I bought two hardened phillips tips to use and they fit so beautifully I had to tap each one gently into the screw. But nothing moved. The phillips heads bear the legend PH3 and I got them at a tool shop. They are very hard.
So Plan B. Laid a board across the engine bay, padding the fenders. Crawled up with a breaker bar and a socket that fit the phillips tips - a 1/4" socket. Then, pressing firmly to keep the Phillips tips from rising out I cranked each one in turn. They all let go with a gentle crack. I then had to fully remove each screw and put it in the bench vice to pull the Phillips tips out, so firmly did they fit, before moving on to the next screw. The long breaker bar contributed by giving me overwhelming force with very little drama and no struggling on my part. Easy to use the other hand to encourage the phillips tip to stay in because of this.
The crankshaft seal was cake. Easy in and easy out. Only hitch was torqueing down the crank bolt. I don't know about others, but using the 14mm socket trick on the flywheel did not work so well. The socket slipped once, then cracked on the second slip. I used a new one, but this time rather than just the socket, I put a ratchet on it, and used a jack to hold the ratchet in place so when applying force it could not simply "lean" out of the way and fall like the previous attempts. So, this worked but was a bit tricky to actually employ.
I used a 3/4 inch torque wrench and had 1/2 inch socket on the crank bolt, using an adapter. That snapped, but was an off brand anyhow. So I used a 3/4 inch 1 and 3/16" socket (all I could find in town on a Sunday evening), which worked a treat and torqued it to about 310.
I did not sand the oil pump cover flat like others have done. Mine had a good surface on it and I feel the cover gets pulled flat by the 7 screws anyhow.
So thanks to all for the tips.
