I just bought a 1988 Mitsubishi Mighty Max it failed smog due to tail pipe smoke when you you Rev it up and egr function fail how do I fix it so i can smog it I know it burns a little bit of oil


You could rebuild it. stop the burning oil( this is a fail). Or dump it and upgrade your vehicle. Another option is to move to a place that doesn't have emissions testing.

Mitsubishi Mighty Max has 170,000 miles on it and maintenance light came on and will not go off


Yes, unplug the battery for 30 seconds, and the ECU will reset. If the light comes on again, get the error code read to see what the ECU thinks is the problem. At 170,000 miles, this is likely burning oil causing a misfire, might be the engine temp sensor wires are broken (causes hard starts when cold), might just be low power steering oil or even worn brake pads causing a low brake fluid level.

Your plugs are fouling out probably from excessive wear on the piston rings. Replace the plugs and check them in about 3 days to a week and see how bad they look. Clean them if necessary and reinstall them. Your engine will burn oil that slips past the rings if they are worn. Usually this will happen when the engine is cold and the rings have not expanded. The expansion is normal so what I suggest is at your next oil change use 3 quarts of the regular oil that you use and 1 quart of 20w/50. The thicker oil will help seal the rings a little better. Don't use more than a quart or 2 at the most because it will make your oil pump work harder causing premature failure.

2003 F150 4.6 w/ 90K miles using a quart of oil every 3 weeks. what's most likely cause?


A V8 engine will start to consume more oil as they get more and more
miles on them. The valve stem seals and piston rings wear, and let
more and more oil burn off in the exhaust. How many miles are you
travelling in said 3 weeks?

Engine rattle noise with oil change light on


Your oil level is low. Wait until the motor is cold and check your oil level. You could also check your level after a drive just shut the motor down and wait 20 minutes for the oil to seep back down out of the block. Pull the dipstick, whipe it clean and did it in again and see what your reading is. If it is between Min and Max towards the middle of both it is fine. If It is all the way up by Max you may have too much, but I bet your oil level is low, I bet when you check it, it will be down near the min mark. If thats the case, find out what type of oil your car uses and buy one quart of oil and add some of it to your motor. I recommend you add about a quarter of the bottle, then stop check the dip stick if still low add a little more. If the level is good then stop. It is critical not to add too much oil. When cars get older they tend to run hot and burn oil. My van does the same thing, I can change the oil and add 5 quarts and about 3 weeks to a month later I have to add a little more and I usually can hear when i need to add some oil because I get a rattle/ping and the idle just doesnt sound right, but once I add the little bit of oil everything is all good.

Burning over a quart of oil every two weeks


you more than likely have some bad rings.

Go to autozone and buy a bottle of Lucas oil treatment, and add it to the oil, if this does not solve the problem you will need an engine rebuild.

Sputtering during idle blue smoke


You are burning oil, causing the blue smoke. It is mainly cause by worn piston rings. Also will coat your spark plugs with oily residue. Try an oil additive such as "stop smoke" or another such brand to reduce burning your oil and it may recondition your seal sand stop it all together.
