white smoke on argo avenger

[brebett]

Hi guys, I have a problem. I have read that white smoke happens when there is a blown gasket. The causes for blown head gasket is overheating. It happens last spring in a cold weather and I never saw the engine overheating. Everything was going ok then on the next day it started to smoke ( white). Beside overheating what cans cause that white smoke.
Also what is the compression on the kolher 26 hp from the avenger 2004 and what about the torque.
Thank you

Generraly white smoke means whater is getting into the cylinder somewhere. I would assume failed gasket... Gaskets can fail for reasons other than over-temp.

I would do a bunch of testing, if the smoke appeared over winter it is possible the block froze.
Check what you antifreeze protection level is at. Is radiator low? Water in oil? etc....

This 26HP Kohler from 2004 is liquid cooled? Regardless, white smoke is steam (burning coolant). A blown head gasket is the most likely cause, a cracked block or head is the worst case scenario.

My favorite test is remove the rocker arms which you will have to during tear down anyway. Fill radiator completly so coolant seals the fill neck. Remove spark plugs and apply air pressure to cylinders 100 psi minimum. If you get coolant pushing out of radiator you have a leak internally. usually only need to apply air for a few seconds if it is leaking. Expect to resurface the heads when apart. A piece of wet sandpaper taped to flat glass will do nicely if you spend a few minutes at it. Good luck

Hi thank you guys. I just checked the compression and both are equal at 175. The dealer told me that they should be around 130 he thinks. So if the compression is good what could be the problem for that white smoke?

[Canadian_Zuk]

Are you losing coolant? Is there any signs of water in your oil? Is it milky at all? Pull your plugs and take a look at them, they should be tan in colour and have some traces of carbon on them. If your burning coolant one or both will be spotlessly clean, as in steam cleaned lol.

White smoke can also be from bad fuel, the new mixed fuels break down quickly, and belch white, and smell kind of putrid.

I just started the argo. It starts like a brand new one. After a minute or so a heavy white smoke come out with a bit of black smoke for a second or two then no more black smoke. The white smokes is so heavy I can't see around me. The oil seems ok and the plugs are ok

If it is coolant the smoke smells of antifreeze and can give a bitter taste in the mouth. I would air test it.

Pump some fuel out and have a look see.
Have you checked the air filter for critter dwelling, water, oil?

Also a bent pushrod can cause excess compression and for crankcase pressure through breather, RARE.

[brebett]

I will look for the fuel tomorrow. This winter I changed the air filter the inside tube and the outside tube. Is there a way to put them on. Is the blocks part going towards the carb or towards outside. But I tried without the air fister on and it did the same.

[brebett]

I don't smell any antifreeze

You may want to check valve guide seals, oil may be leaking back into cylinders after shut down

Possibly diesel fuel in your gas as well. Take off the fuel line buy some line and run it it a good known gas can and see if it does the same.
