Isx 600 series coolant loss

Howdy
I have a 2007 Pete with a sig. Series 600 isx. I have been putting 2 to 3 gallons of coolant in a week. I see a leak around the egg cooler towards the front that does drip but looks crusty all the time even after hosed off. Mechanic said he sees it and that the exhaust manifold around injector 1 looked to have a leak? He was worried about coolant in oil or the liner bit couldn't tell unless he took it apart. I'm obviously don't have the money in a owner operator . Oil is not cloudy engine had a inframe about 60000 miles ago. I habe a loud noise like exhaust back air or something with change of rpm mainly uphill coming from engine area down low . White smoke out of passenger stack on idle and sweet coolant smell. Black puff out drivers stack when the noise or loud burp or cough happens???? Any help would be appreciated. Also any chance blue devil or vertex would buy me sometime?

 

Yeah I'm thinking so to. I'm pretty sure it's bad without even taking the back apart to check for coolant. Its leaking out the front side even. But i need to take a load Friday and this has been going on for a month. I don't want to ruin the engine. But i need to make money to fix it. And i hope the cooler is the only problem . I habe heard mixed reviews on the coolant stop leak products . Although some swear they work.

 

I'm worried about the white smoke coming out the stack on passenger side . I am not a mechanic just barely shade tree. Bit im assuming that could have something to do with my coolant leak . It has gotten worse I believe since my egr seems to be in complete failure?

 

So how is it burning it ? Just trying to understand what I'm ruining in my engine .
