Engine shakes while engaging blades

[JimP2014]

Ilengine,

I did check the bolts and they seem fine ( engine mount bolts 4 of them ). The engine is producing white smoke in the intake and that test was just running without blades engaged for say 2 minutes. Also about a month ago there was oil being sprayed around the engine. I thought it might be the valve cover gasket, so I did fix this and the oil spraying stopped. But no it is back again. So under no load the oil gets sprayed near the oil filler tube and then on top of the engine shroud. I will pay close attention to this today because 1 month ago I made a video of oil bubbling along the valve cover gasket. Maybe it is this again or maybe it is the head gasket too. I think the "mower deck" might be OK. It is tough not having "you folks" around to actually see what is going on and people like myself where I am not sure what to listen to or look for. But often times forums like this does work out. It might take me a week to figure it out.

Here is the left side of the mower deck from yesterday:

So oil sprays under no load and the engine struggles with blades engaged. This is where it is at.

P.S. Forgot to mention there is a "very metally" sound like something is grinding.

Seems like the deck belt is shaking really bad. Check the V pulleys for something stuck in the groove, or check the deck belt for an area that looks like it has burnt to a narrow area, or a bent pulley.

Head gasket failure usually results in oil consumption and smoking out the muffler from the burning oil.

I just made this video seconds ago so here's the setup just start up the engine it starts up perfectly do not engage any deck whatsoever and let it run for a minute that point the exhaust pipe is 600° f or more and then there's white smoke coming out of the intake so I think I need to start here and not worry about the deck right now what are your thoughts on this?

Let me add this last year I had about 50 different things going on that had nothing to do with a mower deck the only thing I did was I bought a new carburetor and it solved everything I'm wondering if this is a similar situation?

So I'm on my phone and I took a picture of the image it's definitely a blown head gasket I've seen others were where gets ruined and this one is in exactly the same place but that is definitely the problem hopefully there are no more problems so it's a blown head gasket

Blown head gasket image.

THAT is definitely blown. No question.

Now is the fun part. You must clean and lap the head and area on the block where the new gasket sits. I use 220 grit wet/dry paper on the garage door window. Go to 400 then 800 grit. Let the paper do ALL THE WORK. Don't press hard and rotate the head around while lapping.

Also get some high tack gasket spray and fog the gasket. Torque the bolts after mowing a few times.

That white fog looks to be atomized fuel. As in the needle and seat not sealing proper.
