I could smell the coolant, but not see any drips. I looked at the rear of the engine, and sure enough... coolant stains on the torque converter cover. Shitballs!
I still drove it for a couple months but kept checking the coolant level, it never dropped more than a cup per week, at most.
Then the drips came... on the garage floor. Not much, mind you, but enough to leave a bit of a mess.
Anyway, I decided "what the heck" and brought it to a Euro Special shop near me that I've used when my injector took a poop.
Sooo... a couple weeks later:
It turns out the leak was NOT from the crappy plastic pipes under the blower that were leaking, it was from the oil cooler. Too late now!
Regardless, it's time to go all-in.
ALL the plastic lines replaced, even the vacuum lines. (there were a LOT)
Replaced the perfectly good water pump, 70,000 miles, why not. Used the latest iteration
S/C isolator and oil replacement, check all the bearings and such.
New oil cooler seal, or whatever it was.
Four new injectors on the side that WEREN'T replaced when my #4 went bad.
Check intake valves for carbon.... very little so a pass on the cleaning.
New MAP sensor, since it's a pain to get at when the blower is installed.
New blower belt.
New Accessory belt.
A total swap-over from water based coolant to Evans Waterless coolant. Hush up, it works just fine.
Complete look-over for any other areas of concern (all that was noted is "Engine cover missing" which is in my garage, and one gooey bushing)

Now, several thousand dollars lighter in my wallet, I'm dozens of thousands of dollars happier when I drive the thing.
TOTALLY WORTH IT, even if just for peace of mind.
They even washed the thing.

 

Hope you did the PCVs too, about $80 for new ones and basically no labor when all else’s removed. I’m assuming you did the valve cover gaskets (super common problem after
70k miles) and supercharger gaskets too.

Interested in your feedback on Evans. Just converted the XKR to Water Wetter, better cooling and safer on the track.

 

Yeah, I think everything replaceable was replaced. Not positive though.

I've used Evans in my track cars for many years. You know, since antifreeze/coolant is prohibited. Yes, the temps seem to be about five degrees hotter at the top on full-grunt, but who cares? Other than 1/2 of 1% performance difference, it won't explode and leave me stranded. Of course, I'd still do something else over 230 or so, because then something else is wrong. On that vein; I was driving uphill, stop and go, at 5200 feet altitude, and 110F in the shade (if you could find any) and my temp did get up to 223F. Meh. Everything is fine.
Of course, I SHOULD have gotten a bit cooler of a thermostat during the whole process, but totally forgot about it.

Water Wetter works okay for a bit lower temps, but water still boils at 212F at 29.92 barometric, and water wetter won't do anything to stop that. You need a good coolant system for that, and watch the temps close. A 15 pound cap will increase that to about 250F, but if it's a second too late...... BOOM and everything goes spraying everywhere in the world.
Plus, with Evans, there is no thermal expansion pressures. Running and at 250F, you can take the radiator cap off just to look at the level for fun.

Edit:
I DO have an Oil Catch Can and all hardware also that I've been meaning to install, just haven't yet.

 

If the blower belt is the serpentine belt, what does the accessory belt drive?

 

There’s two belts, one exclusively for the supercharger (blower) and one for everything else.
