89 honda civic fails smog

I have a 1989 honda civic that never had smog problems till after a rebuilt head was installed. Mechanical timing is dead on, checked with timing light as well and dead on 18BTDC. Engine has new head, new air filter, oil, oil filter, o2 sensor, raditor, plugs & wires, distributer cap and runs real good but fails too high hydrocarbons? What are most common thing I should check. I really dont have a lot of money to put into this car so I would like to be able to test my parts before replacing them.
Thanks Brian

Bingles,,,have you changed the oilseals on the valve stems or used the old ones?these tend to harden after a few years and even a slight leak may lead to high emissions, also v,important did you use the old head gasket or replace it? always use a new gasket as an old one has already been compressed and may cause a cross-flow leak into one or all of the piston chambers.
hope this helps.

Try to re adjust your timing to 12 BTDC to have a complete burn on your AF mixture.

My 1989 honda civic recently failed functional check becauhe mechanic saied he could nnot find any btiming marks on the balancer. is there timing marks on 1989 hondas aned should my car be exempt for...

there there they probably just are not as easy to see as they once where. here will be a pointer on the timing cover and there will be four notches on the balancer, three close together and on space a little further than the other three. At one time the center notch in the three grouped together was red.

The balancer may need to be cleaned a little with some sandpaper to make them visible but they should be there.

The other think that comes to mind is there might be a rubber plug in the transmission under the distributor. Some of the older honda engines had this, I don't remember of hand which ones. When you remove the plug you will see the notches and timing marks.

Go to faxonautoliterature. They list at least 3 separate Honda service manuals for that car, one of which is for diagnosing electrical problems. I have used them many times and been very satisfied with the pricing, delivery and service. Just follow the directions on the home page. Hope this helps.

89 honda civic lx overheating

Thats my guess, one hose leak, two head gasket, three, crack in head somewhere. Of course make sure the thermastat is working. If it is seized thats a problem to. If you get the head off make sure it is resurfaced before you install the head gasket. Good luck
