I've been fighting with the dreaded misfire on all cylinders codes for a while now.

I did a compression test early and the results were pretty good. However. I replaced the injectors and the codes went away for about 10k miles. During that time, I overreved once (stupid mistake, went from 6th to 4th when down shifting on the hwy).

The car seemed to be fine, but later the CEL came on again for the same 4 codes. I thought, "ok something else is going on." Well after sending my old injectors to witchhunter for cleaning, and replacing the map, checking everything else electrical. I did a compression test again.

Compression results:
cylinder 4-2 = 240psi.
cylinder 1 = 90

Did a leak down and it's definitely the valves. So looks like I'm going to start the tear down this weekend. Hopefully the parts will come in from Honda on Monday.

Here's a list of parts that I'm buying today, is there anything else that I may be leaving out? Ignore the tb gasket and interior pieces. I just was going to go ahead and get them too.

14711-PCX-000 VALVE, IN. (YELLOW) (NIPPON HATSUJO) 2
14721-PCX-000 VALVE, EX. (BLUE) (NIPPON HATSUJO) 2
14775-PCX-000 SEAT, VALVE SPRING 4
12251-PCX-004 GASKET, CYLINDER HEAD (NIPPON LEAKLESS) 1
12211-PZ1-004 SEAL B, VALVE STEM (NOK) 2
12210-PZ1-004 SEAL A, VALVE STEM (NOK) 2
18115-PCX-014 GASKET, EX. MANIFOLD (NIPPON LEAKLESS) 1
17105-PCX-004 GASKET, IN. MANIFOLD 1
16176-P73-004 GASKET, THROTTLE BODY (NIPPON LEAKLESS) 1
77320-S2A-003ZB COVER ASSY., PASSENGER INSTRUMENT (LOWER) *B135L* 1
77120-S2A-003ZB COVER, R. FR. CONSOLE *B135L* 1

 

You can consider the valve cover gaskets:
12040-PCX-305 GASKET SET, HEAD COVER
12342-PCX-004 SEAL, SPARK PLUG TUBE (NOK) 4

 

Instead of buying all the gaskets separate go with 06110-PCX-020, its a full gasket kit for the top end.

It comes with:
Head gasket
Valve cover gasket
Spark-plug tube seals
Valve stem seals
intake manifold
Exhaust manifold
Exhaust donut
TCT o-rings

 

I thought about that, but I really don't need a lot of those gaskets. Trying not to spend more than I have to on this. Going to be changing jobs soon and moving 300 miles from here, so on a tight budget.

Thanks for the recommendation though.

 

Over revved, hwy, 6 to 4? In order for that to happen you have to be doing about 120ish and shift to fourth. Sounds reckless. But it sounds like you know what you are doing. Good luck

 

I could see going from 6th to 3rd, but how do you go from 6th to 4th?

 

damn man I was doing about 120ish and went into 4th gear too!! the tach flashed twice before I caught it! Hopefully my valves arent f**ked up!

 

sh1t happens lol....

 

Damn. I could have swore I typed 5th to 4th haha. Oh well. Shit happens haha.

Out of like 15 vehicles that I've owned, only 2 have been automatics, you would think that I would know how to drive by now haha. Live and learn I guess.

 

nope 6th to 4th. oh well
