Thanks for the input but I think that's a Lil too much I just need it to know if it was an engine problem or just that the water burns fast in that engine because I fixed the leak and I still have to put water in it that's why I don't put in the coolant yet

That is a classic blown head gasket symptom, but some times it is a cracked head.

Look when I took out the spark plugs they had oil in them and I the shaking stops as soon as I idle the engine a few times when is cold wouldn't this be a valve cover issue

You already stated the you are loosing coolant and you fixed the visible leak, besides if it is a valve cover leak oil cannot get into the combustion chambers from there unless you didn't put the spark plugs in properly and it is running down the threads of each plug. Perform a block check that will tell you.

Only in semi Diesel engines in the old school systems, on the newer even they tend to shy away from it. That stuff is just bad news it will plug up a lot of things, heater cores radiators, small coolant ports in the engine.
