I'm looking for some advice here. A couple nights ago when I got home, I noticed that my '91.5 was leaking a lot of black sludge. It looks like the coolant system is filled with oil. There was no loss of power, odd sounds, etc. The truck has ~ 215k miles on it, and I've been running a HE351 turbo for a couple years with maximum boost reaching about 29 psi. It has an easy life serving as my daily commuter and occasional tow rig.
The two thoughts I had, is either the head gasket is compromised, or the oil cooler cracked. Is there anyway to confirm which of these it is? Is there anything else it could be?
What is the best way to go for reliably holding increased boost on these VE motors? I have had thoughts of putting a slightly bigger turbo on it. What boost pressure is a stock head gasket and studs good for? Does an MLS gasket from a 3rd gen fit?
Here's an ugly picture of what I was met with when I pulled the radiator cap:
Thanks, Eric
