Civic has Knock

Recommended Posts

I have a friend that has a 2000 Honda Civic with a 1.6l and 5spd manual. The car has 105,000 miles. Apparently the girl driving it didn't put oil in it. The engine developed a loud knock, it never seized so it must haven't had been run dry. But is was run low enough to obviously start a knock. They said it still runs fine after they put oil back in. It just now has a knock. I am thinking of buying it from them for my daily commute with 3.00 a gallon fuel prices. I have 46 miles a day max speed 60 mph for 9 miles. I havent drove it yet to see if it could make these speeds. But I figured if it would it would be worth the 100-200 they want and drive her as long as she'll run. Question is which oil will help it run longer, since oil killed her what oil will prolong? Heavy ? Synthetic I am sure? but what weight ? Maybe something with lots of zddp, or even an additive like slob...........

prolly rod bearings. you should just fix it, else it will most likely get worse....

it wont last. i give it a matter of miles and its done. if you keep driving that car without simply putting bearings in it , its gonna blow and a 100 dollar fix , turned into a 1000 dollar fix. some engine pyro can handle the knock for a while , honda engines cant. usually when a knock developes in the bottom , its a matter of minutes , not miles. ive seen some 3.1 litre V6 chev engine like luminas(or 2.8 , same engine) , go for a year with a very noticeable knock. some can.

what is the likely hood it is only the bearings. Could it have effected the crank? Also how difficult of a job is this. Never touched anything Honda.......

it is the rod bearings. is there damagae to the crank you dont know till its apart. if you change them now , it would take you a couple hours and about 40 bucks approx. whip the oil pan off and replace them. but if theres damage to the crank or the rod journal , new bearings will still be a temporary fix.
