-the complete machine was done a year ago
-there is no water in the carter, or oil in the water tank
-They 150 psi in each of the cylinders

thanks beforehand thanks beforehand beforehand beforehand beforehand beforehand beforehand beforehand

Hi Javielito86, it would be good to tell us if it is diesel, if the smoke smells like burned oil or diesel, if it does only hot or also in cold ... if it is gasoline, some greased spark plug that makes you think of a broken grease segment ... if the valves were also changed in addition to the guides, if you consume oil or more fuel than normal ... it will be more easy to give you an opinion. Greetings!!

Hello everyone, Javielito86. For the compression (150 psi) I imagine that it should be gasoline. Would it be good to know if the problem was shown immediately after the engine had reopened or was shown gradually? The other, thinking, I saw a case that because of an injury dripping, the oil with benzina was contaminated, diluting this (loss of viscosity) passing to the camera after 2500 rpms approx or applying load to the engine. This assuming that the smell of smoke is to oil, which ismael expresses is important. If it has no oil smell, it can be refrigerant ... the glycol and additives that contain produce a smoke like the one described. Finally, but much more rare, if there is no cooling or oil consumption and white -blue smoke persists ... I have seen very rarely that due to rubbing brake pump rubber Exhaust, but it is very rare and liquid consumption and problems in the brake system should be noticed.
If the problem is oil consumption in the engine, they must be noticed in the spark plugs, the waste in each help identifies if the oil passes to one or all the engine cylinders. Oil consumption, with good compression, smoke ... It could be what Ismael says, segment rupture or greasey ring, or incorrect or inverted posture of the oil sweetener (2nd to revex). When it is for the guides or stamps of female valve more decelerating and when leaving a semaphor. Tell us how it went ... well I don't give the can ... greeting everyone.

I apologize, I had not been able to enter the page, I always gave me an error

ismael53 the vehicle is gasoline, and if oil appears in the four spark plugs, it consumes oil but not gasoline, the guides, valves and stamps were changed.

Fiat147 What you mention about the "oil consumption, with good compression, smoke ... It could be what Ismael says, segment rupture or greased ring, or incorrect or inverted posture of the oil barred ring (2nd to revex). It is what must surely be happening, it is already in the search of the rings to change them, thank you for the help.

What happens is that it is burning oil and causes the blue smoke to take out and can even have a bad smell the smoke that escapes from the escape ...
I hope it is served.
