Sooooo I bought a '99 Civic LX with 165k miles. It's all stock, the person I bought it from did some major repairs/maintenance. He replaced the water pump and timing kit. And put NGK platinum spark plugs in it. That's just the relevant items. Now since I owned it I have driven about 1500 miles and had some issues. First problem started the first time I drove it more than ~30 miles I pulled into the drive through of a burger joint and the water temp started rising, so I revved it and it dropped almost instantly. So I burped the air bubble and added distilled water. Fixed! For now...

Next trip we drive 195 miles to the coast through the mountains and such. All was good on the way there. On the way back the water temp started to rise again. So we took it slow, stopped when we could, and kept the temp down. Then it lost power, wouldn't happily rev past 3500rpm and had no acceleration. Found the seal on the radiator cap was broken. Needless to say, I towed it home 88 miles(thank you AAA).


At home, after new rad cap, I found the platinum plugs and my history with anything but OEM plugs told me I need ZFR5F-11s now. So did that. No change still will not rev past 3500rpm. Next, I removed the distributor and disassembled it to find bearings going bad (explained the bearing noise between 1500rpm and 2500rpm...) and a coil with a hot spot. New distributor, done.
Same issue no rev past 3500rpm but also now I CAN NOT set ignition timing. I jumped the "service check" connector. I can hardly see the timing marks on the crank pulley; it's as if they are retarded 20 or 30 degrees. The timing light has an advance adj. knob, if I turn it to anything between 20 or 30 degrees the marks can be lined up with the distributor. HOWEVER, IT STILL WONT REV PAST 3500rpm and it stumbles at idle.


Help me with my troubleshooting?
My theory is that when the person replace the timing/water pump kit, he got the cam timing off one tooth. He had no reason to adjust ignition timing with the distributor after the job because it ran good enough and he hadn't touched it.
So the cam is a tooth off and I can't get base ignition timing set?
Tomorrow morning I will start with replacing the fuel filter. Then I will check the Cam/Crank timing.
NO CEL AT ALL.

It jumped a tooth while you were driving is more likely than it always having been a tooth off. Hopefully you didn't overheat it too bad and warp the head. Check timing first then compression test before anything else.

Found the problem...



New theory: Bad rad cap caused overheating, overheating caused coil to melt, coil caused backfire, backfire caused tensioner to break.

And here we are...

x2 the belt probably wasnt tensioned correctly, and "shit head" sold it instead of fixing his fuckup.

The plan is to finish it today.

Yesterday I replaced the oil pump seal, installed new water pump and complete timing kit, triple checked mechanical timing and started reassembly.

I have all the parts I'll need. I still have to adjust the valves, flush the radiator, fill it with fluids, set ignition timing and double check everything...
Should be good to go this evening.

Things did not go according to plan lol :willy_nilly:
Yesterday I made great progress but I hit a snag

So I made a special trip to the dealer for this little guy last night before they closed.

I'm going to run a compression test :fingersx: then flush the coolant and start fresh with a new thermostat.

I have feeling it's not the orginal engine, is there anyway you can check the vin numbers. They should match
Original engine, original transmission. Matched all VINs before I bought the car.

Can you, like... find a bigger rock, and pretend the bigger rock was the one in the oil pan... and "return" the rock to the original owners face? Please???

wow, wrong crank key, probably did not do the 2nd loosen and retorque on crank bolt or tensioner bolt, and appears rushed a bit.


This is why it took me 5 hours to do headgasket and timing belt at same time. wanted everything clean, set correctly, and done per tech manual.


Good job on having patience and checking everything out.

I personally would have missed that loose sloppy crank key. Good fucking catch!

Thanks, yes definitely rushed and maybe self-taught...

I have learned over the years that patience and accuracy means less chance of having to do it all again because of something silly. Take the time to do it right the first time.

And you probably would have noticed that key, there was at least 5° of play in either direction. I noticed when starting the bolt, the pulley shifted but the crank stayed put. Uh oh. Lol

Also found a nice crack in the radiator top plastic section.

So new radiator and hoses, which means the entire cooling system has been replaced.

Also compression came back 185 180 185 190

All valve clearances we're .003 over Max spec.

It runs so much better.

Holy #$%^ if I found a rock in the oil pan I'd be having some serious words with the previous owner. thats ridiculous! then again just the fact that it was jacked up by the oil pain is enough for me to seriously question how adept they really could have been...

Haha I was pretty flabbergasted when my wife cleaned it off and said it was a rock. Based on the oil deep in it's crevices, I'd say it's been in there longer than the time the guy I bought it from had it. Besides that it was under the baffle and could not get to the oil pickup, even if it could it wouldn't block the flow much and definitely wouldn't have been sucked up by the pump.

So there's not much to gain from getting angry. But thanks for the concern​

I think the biggest mystery here, is how the hell does someone get a rock in there? I almost wonder if it wasn't an accident, like maybe a previous owner wanted it to blow up and thought they were being clever, or maybe trying to prove a point that it wouldn't blow up?
