I have a 2009 LMM with 135k on it. Its been deleted and tuned with H&S Mini maxx. Its been deleted since November of 2018. The EGR cooler is off. Ive been having issues with losing coolant since May.

I've had it taken to a shop twice and they pressured it up and couldn't find a leak. I had noticed a couple times while passing highway traffic with heavy acceleration it will spray water out of the passenger front fender well. Which I assume is from the reservoir.

Any help is appreciated! Thanks

I could go out to it after its sat a bit and see my coolant is low. I could open my reservoir cap and itl pressure up. Its a coin flip to see if ill be low or at the line.

It doesn't white smoke at all while driving. I usually add coolant once to twice a week.

That's what I've been thinking as well just seems the shops around here don't want to dig into it. The last shop I came from said drive it until it got worse.

If it pushes coolant out of the tank on the passenger side under a hard pull it’s head gaskets 99.99%

Head gaskets x10
Blowing coolant out the reservoir when putting the engine under heavy load is a pretty full proof diagnostic.
