Noticed underneath leaking for a while, finally bought this O-Ring part from Honda dealer for $2.52 while doing something else.

Remove the spark plugs from the tubes instead of the distributor cap, this way, I won't be confused about which cable going where.
Then removed 3 bolts holding the distributor, the inner bottom one fell off, need some long needle pliers to pick up, so be very careful. Put a paper towel under the distributor to absorb any spill. Loosened up the distributor by twisting it and pulled it out.

Marked the tip of the crescent shape with a Sharpie to preserve timing, this is very critical in order not to mess up the engine. Cleaned up the leak and surrounding area with paper towels. Used a small flat screw driver to get the old O-Ring out, it is very fragile already, so it was broken when pried on. Put on the new one with ease while there was still engine oil around the axle and itself being flexible.

Made sure the marks lined up, then put it back in, and twist a little bit until it is full engaged. Should had put the inner bottom bolt in first, because it slipped again and needed to unscrew and pull the distributor back out to pick that bolt. Otherwise, it is an fairly easy job and saves you quite some sweet bucks.

Back in November, 2016, PC died unexpectedly with just some noise from a fan inside. It could be a combination of CPU, mobo, and PSU went wrong, to be on the safe side and get the work horse back in short time, I replaced all 3 of them, along the way, 4GB memory upgrade to bring total to 8GB and a brand new 1T hard drive, so I can reuse the old hard drive someday. But the new mobo is bleeding edge, requires USB3.0 preloaded from OS DVD, so my 2009 Vista Ultimate was obviously out of date, not even windows 7 can do the job, therefore, more money for a new OS - Windows 10 pro, since already spent money on OS, would not mind a couple dozens more for a decent pro version. After all this new PC is up and running happily, I have time to look into the old stuff, first took the PSU apart, found some bulged caps.

Also noticed a black line was severely burnt due to current overload. Took out the bulged caps.

Replaced those 470uf/16v caps with not exact caps 1000uf/16v, problem persisted, found primary caps leaked.

Took out those two primary caps in a bank.

Not even Radio Shack has matching caps. So project put on hold.
Needed to check CPU and mobo, bought an EVGA 600W on sale from BestBuy for $34.99 which is very good for a major brand with quality, hooked up the new PSU with the old CPU/mobo, shorted the power pins for a second, the CPU fan ran right away, that gave some hope of just the old PSU being the culprit.

The law put simply says that life of a capacitor doubles for every 10 degree Celsius decrease in temperature.
The old PSU's fan was stuck due to lack of oil/lube at the bearing, after adding some w40, it could turn much easier.
This broken fan might well fry the caps.
Never, ever save on a power supply again!

This was an old project done a couple of years ago, but still worth demonstrating it to show how hardware and software can work in a nice fashion, cars these days use a lot of technologies, a controller is the heart of it. The Arduino UNO board is about 11 bucks now, and the LCD is about $14. They can build some nice project around the house, like a water leak detector. Back in the old days, we would be thrilled to make an AM/FM Radio, that might well pave the path for today. Hope kids these days would have the same heart and soul.

This car had some 156000 miles on it, could see some oil stain around valve cover and engine block area.
Removed the spark plugs, the connected rubber tube, and the PCV valve, unscrewed 5 bolts which hold down the cover, since it had never been opened, so it was hard to come off, used a flat screw driver to carefully pry along the seam until it loosened up, took it off. Then used the tabs to pull out the gasket

Used a very thin and small flat screw driver to shim in tube seal and the valve cover, pried it off the tube, then used a pair of pliers to pull it out, repeated for all four seals. Wiped clean the walls of tubes for new ones to be put in.
20170121-accordvalve2.jpg
Used a big enough socket to hammer new seals into places, then replaced items back in order, when tightening up those 5 bolts, it took a little time to fit, just be patient.
Always get parts from dealer, this way you save a lot of trouble down the road.

I have been thinking of this for a long time since day one I bought this for my wife as a birthday present, it had a timid 8Gb hard drive, always broke down because of the full disk and extremely slow.
I finally shelled out $72.91 for a 128Gb KingSpec SSD, be careful that it would fit into the mini and have the right type of connector (ZIF in this case), Amazon shipped this item to me during the snow storm, so it arrived just one day late.
I made a bootable Clonezilla flash, used it to clone the hard disk to another flash.
I finally had sometime to work on it, first got all the necessary tools ready, took out the battery, remove the 2 screws under that battery which held the keyboard, then push the center top part of the keyboard up, put in a small wedge to hold bend, carefully ply the Tab and Backspace of the keyboard to release it from the tabs, that would expose the keyboard ribbon cable, flipped up the black tab and took off the cable. Did the same for the white small cable and the SSD ZIF cable, remove the 2 SSD holder screws, took out the 8Gb Sandisk SSD and set it aside.

The 1.8" KingSpec SSD is big enough for the entire bay, so needed to remove the internal USB, unplugged the USB connector, used a plastic pryer to carefully ply off the glued down internal USB. The KingSpec SSD did not come with a ZIF ribbon cable, so needed to reuse the old one, it was hard to fit the cable in the new SSD, tried both ends of the cable, the end marked as "mb" was easier to insert, but still tight, in this process, be very careful that the bare contacts face the contacts in the connector.
20170116-hpmini2.jpg
The new SSD did not have any mounts, so made some washers to tighten down the new SSD, then use electric tape to further tie down.
20170116-hpmini3.jpg
I booted up the mini with Clonezilla flash, restored the image to the new SSD.
20170116-hpmini4.jpg
now, the partition was still 8 Gb. So, I made another bootable flash with GParted, first attempt to resize it failed with chkdsk, indicated file system was corrupted, booted into windows XP to run chkdsk /f, then rebooted into XP to finish off disk check. Reran GParted, this time it passed resizing successfully, and SSD got to its full potential.

At this point, job done.

It has been a while to look for a house for JD, we look at a slab year 2000 built single family home, as expected, some small cracks around outside perimeter and inside the garage.
The house overall is kept in good shape, in excellent school district, and priced at high end according RealList.
JD liked the pink room :)

I would like to use this platform to demonstrate the work I have done, my interests. Hope this is beneficial to you if you bump into this site.
I studied environmental and resource science in college, then I was fascinated by Geographic Information Systems and computer science and engineering. I got my MA in Geography and MS in Computer Science from UGA.
My dreams were to check out houses, I have realized this dream, and I am a licensed real estate broker and a proud member of National Association of Realtors, I can use my extensive geospacial, economic, legal and engineering knowledge to help people with their largest investment in life time which is also coined "American dream".
My second dream is to have a garage to do car repairs, I had a very good classmate in graduate school, he was from Russia, he was a fighter jet pilot before, so he was very good at mechanics, he helped me a lot with my car. Cars have evolved a lot, simple tools won't be able to tackle some complicated repair jobs anymore, I hope to use my technology/engineering knowledge to help people with their cars, but I cannot check off this one yet, it involves much more money to acquire commercial real estate, equipment for garage and man power. However, I will post some simple jobs I have done, and you can share your experience, if you happen to own the same make, that would be awesome!
