I was just wanting to sort of take a survey, for those of you who have rebuilt your motors. I want to know what the mileage was and what you did. My DA is at 187k and I’m wondering if pretty soon I might need to rebuild…I have had it for 3k miles and the first thing I did was the PCV valve, and noticed it was bad, kinda scared me because of the mileage…but it does seem to run better. I mean I know Hondas are the best and stuff but if people are stupid like that sometimes you have to fix shit. So let me know.
the b18a motor have been known to go well over 300k miles without a rebuild. as far as rebuilding a motor… there are many things you can do. new valves, valve seals, valve springs, new bearings, pistons, rods, cranks…etc. basically any moving parts that wears down due to friction. most people dont even care for a rebuild back to stock specs… because its more expensive replacing parts and paying labor than just buying another motor and swapping it in. most people here rebuild their motors with racing parts to make horsepower.
That’s good to know, my old CRX got new piston rings and d16a1 pistons around 180k or something like that cause the rings were bad. Then again, my friends 240sx has been rebuilt twice and its only at 140k…Nissan FTL
You know Bacardi, driving style has alot to do w/ it. Peggin the redline too much, bad shifts, not warming up before whompin’ on it, improper/minimal maintence, etc. will certainly bring about the demise of any engine before it would normally happen.
I’m gonna rebuild my B18a1 early next year. Mild on the bottom, (rings, bearings, seals, maybe pistons.) & med. on the top. (cams, gears, springs, retainers, seals, maybe studs too.) It’s got 204,000+ on it. Startin to smoke abit when I rev-down or deaccelerate if you prefer that term. I figure might as well go for broke, as I plan to keep it for a bit, & have no ambitions of more than a well tuned/ maintianed daily driver w/ some beef to it. (160-170whp)
What about you? Got problems or just think it might be time to take
preventative measures?
:getsome: :manual:
Nope, no problems that I can see. It could use a tuneup but it doesn’t burn or smoke anything, so I’m feeilng good about that, just getting worried as I’ve never had a car that has that high of mileage. I drive like a grandma too, shift slow and easy at 3k and I don’t accelerate hard…I never see a reason to, especially cause I only get 23 miles to the gallon and I try to get the most out of it, lol. I thought about maybe starting to save up for a whole rebuild, but yeah it does seem fine.
23 mpg is kinda scary…
That in itself is telling you there’s a problem. You should be scoring 28 on a stock motor, driving it that easy.
I agree that if you arent having any major problems, then you should just keep up with the regular maintenance… Although if you are looking for more power then rebuilding would be a good idea… I personally just built my motor and installed it a couple days ago but I will be going FI…
If you want to learn a thing or two, just find a spare engine and break it down and rebuild it yourself over time if you’re not in a hurry. I’ve just finished rebuilding (waiting for install) over the last year and a bit. By virtue of lucky timing, the motor in the car is starting to burn oil and do funky things. I can’t imagine what I’d do if I hadn’t already had a new motor ready to go in.

I’ve had three DAs now, all three got that mileage. And my first one, I had for over a year, and the only problem I ever had with it was the distributor went bad. It only had 160k when it got rear ended…it was a great car. I don’t think my cars have any problems at all…
23mpg seems normal. I was getting that in my auto DB, and in the 5speed DA I just got, 23mpg too on the first tank that I’ve had it.
I’d imagine if you commute longer distances on freeways you’d get better mileage that those who do a lot of stop and go…
23 mpg is not normal unless you are driving bumper to bumper tappin the brakes every mile. For comparison, I get around 32 mpg on my mostly hwy driven 303K mile B18A1. But I do have it running very well with I, H, E, and a 7.5 lb Fidanza flywheel. I have replaced most of the ignition components, engine is timed properly, and it runs stong and just sips the gas.
There can be many causes as to why your gas mileage is down, here’s a few; clogged air filter, clogged cat conv., bad O2 sensor, weak ignition system (coil, ignitor, cap, rotor, wires, plugs), jumped cam timing, wrong ignition timing, weak compression, failing electical system or grounds, poor driving habits,etc.
As for rebuilding, it can go from real cheap; replacing only piston rings, rod and main bearings, and valve seals, to very costly; replacing every component such as the ones above and water and oil pumps, pistons, all seals, belts, hoses, etc.
And its easy now to upgrade the performance, because all the research has been done by others. For a nice bump in power, I, H, E, better cams, matching valvetrain, higher compression pistons plus a tuning session will go far, but will add to the cost. Research is the key.
If you take your time and research, you can do all the work yourself, except for some machine work if necessary, and save alot of money.
Many will choose to just buy another engine, but who knows how many miles are on the used engine. But if you rebuild, it is like a brand new engine with 0 miles and a full life ahead of it. Blah, blah, blah, I’ll shut up now.:stare:

32MPG, I can only wish…
Unfortunately for me bumper to bumper is the only way to go for me. To put it in perspective, I travel on average 15-16 miles EACH way everyday. Distance wise it’s really not that far, but what hurts is that it takes 30-40mins to go that distance. To say the least, our roadways here are poorly designed which contributes to crappy traffic flow.
Back on topic though, you pretty much hit it bang on with the rebuild suggestions. Much of what you have said is what I have done.
Nice, now if I can just practice what I preach, lol. My problem is the money flow, or lack thereof. I am fiscally challenged. I have been selling rebuild parts that I saved up for awhile now, just to pay the rent. The 404 Crowers are going to break my heart when I see them go. Hopefully I start work again next week.
I actually got 375 miles on a tank not to long ago, but I still manage to gripe about the gas prices. I am positive if I ever make an all hwy road trip and stay at 70mph constantly, I could get over 400 on the tank and around 38mpg.
^ Very possible. Last year i rode with my brother in his integra down to our favorite beach in Delaware, which is now my integra because he bought a DC…bad choice haha. But, my dad and my mom and my oldest brother were in the the other car, my brother went 410 or so miles on one tank of gas. I was shocked. And i fell in love with the car, even though it doesnt look the best. I’ve replaced a lot of parts that looked bad on the car, and added i/h/e…hi flow cat, 7.5 lb fidanza flywheel, and the short shifter to the car, because i love it. I still get in the 30ish range for mpg, usually around the 350-360 range for the entire tank.
I usually get about 370-400 miles a tank.
Don’t feel bad Sam92Teg. I just started gettin’ outta my rut. Keep @ it & don’t give up hope. BTW, are you gonna try to make the Tampa meet on June 16. Should be a good one. Hope to see you there.
:getsome: :manual:
Thanks for the encouragement, and I will try to make the meet.
bacardi, if you really have bad gas consumption problems, start by doing your basic tune-up (spark plugs, wires, dist cap, etc.) and change out all of your “fuel” seals if you think it might be leaky. That includes injector rings, o-rings, sealing rings, and insulators, as well as the fuel pipe o-ring and the FPR o-ring. I rebuilt last October and replaced ALL seals and gaskets and I get at least 35 mpg, whereas the original engine was making about 28-30. I’m not saying replacing these seals will get you 35 mpg, but its a start I guess
Yes, I do need to do a tuneup, but my car runs great, it starts quickly everytime and feels right, except for the slipping clutch. Even my window sticker from when it was bought says it should only get 25 city…
LOL…
