ok i got a 92 civic sedan lx with 199k on it exactly. it burns oil and smokes out the back a little and also has a lil lag in first gear at low rpm. you think this would harm the motor or not? im thinking it may actually help the lag a lil if its a build up but i hear bad things about it but most good. any suggestions?

Seafoam isn't going to help you here.

If it's smoking you've got bigger issues than carbon buildup. Infact- the buildup is probably keeping your motor together.

CARBON BUILDUP > FACTORY GASKETS.

Better to tear down the engine, annodize it, port & polish it, get all new internals, gaskets, and seals, followed by a replacement ECU/fuel management system and all new sensor packs and gauge clusters....


















...then toss it off a cliff. Itll get better RPMs on the way down.

ya not helpfull at all.

I know... its the sarcasm. It rules me sometimes.

In all seriousness, if you are smoking sufficiently enough, you might be burning something you need/want to keep more of, like oil, gas, or coolant. Just using Seafoam is going to be more of a bandaid without figuring out what the underlying problem is. The only real way to do that is to pull out that motor and break it down until you find out whats happening, or at the very least check your seals/rings/gaskets etc.

Additionally, the thumb rule is that: white smoke is usually caused by coolant water (or antifreeze) entering the combustion chamber; blue smoke is essentially due to oil (lubricants) getting in to the cylinder; and black smoke is generally because there is too much fuel (Diesel / Gas) being inducted / injected in to the engine. And grey smoke would be due to a mixture of water and (excess) fuel entering in to the combustion chamber.

its def a bluish smoke so i knew it was oil but the car runs perfectly fine other then a lil lag in low rpms for every gear. also i was told it may be bc of a clogged cat.

If the cat was clogged, you would have problems all over the RPM range. A clogged cat doesn't magically become unclogged at higher flow when the RPM rises.

Given the mileage of the engine, any bogging problems are most likely due to sensors being slightly off or an O2 sensor going bad.
