I definitely understand how you feel.

Looks like now, I've finally managed to not check the coolant (which has ALWAYS needed some weekly since it was rebuilt after overheating) just long enough to cause the head gasket to fail.

I've replaced both fuel pumps, EGR temp sensor ($400 from the dealer because the PO or Kruse-Lucas Dealer in Modesto, CA put a 92 engine computer with an 89 transmission and a who-knows-what-year-engine in it), completely overhauled the front suspension and got a new shimmy within 10K miles, replaced the water pump THREE times now, not including having to reinstall it twice each time (and I also broke off a stud in the block with a torque wrench), two replacement radiators and a rod/repair of the original (read CRAPPY and too small) brass radiator, god knows how many sets of crappy bosch plug wires that rotted in 4 months, and soggy rear shocks and springs and OH GOD THE TAIL-LIGHTS! New bulbs, new bulb holders (with sheet metal circuits), new gaskets, a GALLON of silicone sealant, a new rear air-dam (Yeah, Thanks PO or Kruse Lucas for attaching it with BAILING WIRE), new front wheel hubs (because you CANNOT replace the bearings as the races are integral to the hubs) and new front rotors, which appeared to be somehow flat-spotted as thought the car sat on the ground with no WHEELS on it......

Yes, this car has been a constant labor to repair and keep reliable and try to get some sort of efficiency (should have done the compression check everyone told me to do years ago).

**This actually matters**
I did the same thing with the water pump bolt - used a torque wrench to tighten it, despite being told to NEVER use a torque wrench on any head/block bolt.
I got lucky and it broke off pretty far out of the threads. I grabbed it with vice grips and had to go find a new bolt at pick and pull.
To help with water pump installation (and I've had two brand new Bosch pumps fail on me at the weep hole), pull the fan shroud, fan, radiator, and intercooler. It's annoying buy very worth it. Install the heater tube gasket ON the heater tube, not in the pump, and break off the corner of the timing belt cover that presses on the water pump and makes installation hellish.


Good Luck, and let me know if it's a 90 or later turbo engine (and in good shape) and if you're in CA. Maybe you don't need to reinstall the water pump...

Good Luck,
Will
