Smoking engine on craftsman dls 3500

While cutting grass on the said mower, the mowing deck suddenly stopped. Later I discovered that the spring on the mower engage had broken causing the stoppage. Well, just after that on the way back to put the mower up it started smoking, blue smoke. It has smoked ever since. Thatís been about 3 weeks ago. I have since changed the mower engage cable. I thought that it may have too much oil, so I drained some off and that seemed to reduce the smoke. But the oil stick was in the ďaddĒ section, so I didnít think that was the cause of the smoke. I also checked the plug and it seemed to be sooted. Any help with the probable cause of engine smoke will be appreciated.

The engine is a Briggs 20 hp Intek plus, roughly 10-12 years old.

I too am thinking blown head gasket. With the engine at idle remove the dipstick. If it blows sorta hard out the tube it's a indication that it could be a blown head gasket. A leak down test could confirm.

I did the check as suggested and the dipstick nearly left my hand due to the force coming from the tube. So I guess that means a blown head gasket. How difficult would it be to replace gasket.
Thanks for the advice

That is normal as crank case pressure will do that. The only real way to test is remove and inspect or a leak down check.
