So, lets see - the Miata has been in the garage since late-November, I think I put it on jackstands in early December and drained the coolant, before leaving for a couple of work trips, and then, nothing. Time and motivation have both been issues, between household and work problems. Neither of which are letting up much, but I need to get things going, so the Beetle can go back in the garage and be prepped for the next rallycross season.
Last weekend, this happened:
It took most of a day to get everything apart. I had intended to start cleaning HLAs during the week, but aforementioned problems happened. I did manage to pull them all, and put them in labeled egg cartons, so I can put them back in the same bore I pulled them from. Today, I finally started cleaning them. I set up a little work station to do one at a time:
The clean oil on the left was used to dunk them after they'd been reassembled, and I squeezed them until air stopped bubbling out of the hole, so they should be pretty much full of oil once the engine starts up. After I had a few done, I decided, since they take a little time to soak in brake cleaner, that it would be good to start tackling the valve stem seals during the down time. Started by using the rope trick to keep the valves from dropping.
Used an impact tool I found from some youtube videos, and it worked fairly well. The biggest problem I ran into was I need to hit it a bit harder with the hammer. Multiple times, I only ended up getting one valve keeper loose instead of both. Putting them back on with the tool was pretty easy, too, but there is a chance I nicked the HLA bore on one of the intake valves. I couldn't actually feel any damage when I ran my finger over where I thought I hit it, so I am hoping all is well.
Today, cylinder #1 has had it's valve stem seals replaced, and 6 of the 16 HLAs have been cleaned and oiled. Since I'll probably be doing this over the course of multiple days, I made a quick chart to keep track of my progress. Here's a pic of it I took during the middle of working on the car:
