The side seals for the rotors are bad. the only thing you can do is pull the engine apart and replace the seals IF the side housings are good. If they are bad, you cant machine them, they are JUNK. Find a shop that rebuilds Mazda Rotary engines. Mazda may be the best place to get a reman engine.

My man tga truck is having hard starting and when it runs it produces too much black smoke when you accelerate but when idling its normal.


check for turbo failure, loose turbo hoses or cracked intercooler
at idle the amount of air is correct for the fuel setting but on rpm the fuel increases but the air increase is missing
run fault codes

It has a seeping head gasket! This is a common problem with all import engines. They are not designed to run hot! Even if they have a lot of miles on them, this problem always seem to follow. If you are familiar with running compression test on a engine, I highly suggest you run one on your engine. Run a compression test with it cold and after the engine is warmed up. If the compression is lower once the engine is warm, your head gasket is leaking compression, and its pulling oil from between the gasket into the cylinders causing the smoke. Or it can be a combination of a seeping head gasket and a bad oil seal on the turbo too as well....

My 2006 bmw 750i it smoking sometime white smoke


White smoke comes in two forms

On start up it can be unburnt fuel

While driving vehicle, motor warmed up ,
it is coolant in the exhaust,usually a bad head
gasket

If your bmw has a turbo,then a problem there,
from motor oil associated with turbo problem

Hi, I have a 2005 hilux 3.0 turbo Diesel , it started blowing blue smoke at startup from cold at 130,000ks . Once it warms up a little it clears.


There can be several reasons for this. You can have worn valve stem seals on the valves, which may change with warm oil, or you have worn oil rings in the cylinders.

A compression test when the engine is cold would reveal if the piston rings are worn. Another possibility could be a bad head gasket which leaks oil when cold and then seals when the heads warm. A compression test would also diagnose this.

HEAVY SMOKE AFTER ENGINE HAS WARMED ON MY FREELANDER AUTO GS


Rings maybe?? Run it till it smokes then remove a couple of glow plugs & inspect the bores to look for evidence of oil. Does it smoke when u first start it too?? Or only once it has warmed up??

If your after market turbo is blowing oil into the engine, best you have it removed. When you say that fuel may be leaking into the cylinders, it could be leaking fuel injectors. If the smoke out of the tail pipe, it's usually indicator of burning coolant. Blue smoke is indicator of fuel and black of oil.

1995 Mini-Pajero. After my car warms up, It smokes profusely from the tail pipe. (White smoke) If I drive around at a higher RPM it eventually stops and does not start smoking again. But If I stop and...


Certainly sounds like a head gasket. The coolant level will take a while to drop, but it will. A cup of coolant can make a lot of steam, and and oil would be blue smoke, not white.
Try running it with the rad cap off, and see if there is a constant flow of bubbles coming up in the rad. If there is, it's bad news.
Good luck.

87 RX7 - smoking exhast for several miles then stops


well,when you turn off the rotary it leaves oil and gas.so when you start it up, it burns off the oil you left causeing blueish smoke. same problem with flooding,when you drive short distance , warmup incorrectly or if use synthetic oil.to fix the cause of flooding(i have the same vehicle and problems)let it warm up for at least 15 min.there is also a fuel pump wire next to the fuse box located above the brake pedal.then you tap a switch from the fuel pump to your interior.the reoson being is so whenever you come to a stop to park flip the swith.that allows the rotar to burn the fuel left in the pump witch will make your rx7 to stutter out and die.when you start it back up ,flip the swicth back on and it will take an extra second for it to crank over.1 more thing,check your oil every 2-3 fills on gas and change oil every 2000 miles.also redline it at least one a week. i hope i just solved your problem because i love my 87 non turbo and know how you feel.if you want to look at cheap aftermarket parts for rx7 then go to srmotorsports.com/rx7guru.com is a guy that test parts to tell people wats good and cheap for rx7s.i would recomend roll cage and 5 point harness-seats.good luck with your rx7 bro
