The coolant from the intercooler loop is somehow being combusted.

Symptoms:
- When I fill the system, I start blowing white smoke.
- Looks exactly like a head gasket blew, but engine cooling system is fine.
- Coolant disappears from the IC system, no more white smoke.

I've disconnected the IC pump for now to avoid burning it out.

My mechanic is not familiar with the IC system, so I'm looking for some help here... what should we be looking at? Intake manifold gasket? Or something else?

sounds like a bad lam core or o-ring

 

Thanks. Would we be able to tell either of these visually?

Or just try the O-rings first?

 

do rings first

 

What I would suggest is completly remove your intake manifold (You'll have to do that to get to the lam cores and o rings) and get some hoses to hook to the coolant lines. Fill the cooling cores (Lam cores) up with water, and see if you can find where it's leaking from.

I did that after I did my dual pass endplate mod, to make sure it isn't leaking.
If that leak gets too bad, it can cause hydrolock in your engine and RIP LSJ

 

I doubt youll find anything just by putting water in it in needs to be pressuized

 

That would be ideal to pressureise it, but most people dont have the equipment to do that. (Including myself) And doing just a static water test is better then nothing. Besides,
we are only talking about -15 (Complete perfect vacume) to +15 (Or 18 depending on S/C Pulley and boost limiter options) of pressure in PSI anyways.

 

Thanks, I ordered the o rings online, and we'll try those first.

 

where'd you order those o-ring?

 

I'm pretty sure CED sells them. If they're part number 3522676, I know they can be had cheaper elsewhere as well.

 

zzp sells them
