[DML] 6585 Back on the road!

["therealdmcvegas" <dmcvegas@xxxxxxx>]

Well, my car is now back on the road!

The massive coolant leak was a bad O-ring on the Y-pipe, and a 
dribble from the surge tank hose. Not a bad head gasket, as 
previously thought. Where the water from the oil came from, I don't 
know. Compression tests all came out fine, and the cooling system 
held 15lbs steady, for over 10 minutes. I can only guess that the 
loose hoses on the engine, and the vacuum leaks sucked in water spray 
last winter, when I hit the flood water.

I also sealed up all my vacuum leaks, and cured my hot start issue. 
But at a price. When I disassembled the Primary Pressure Regulator, I 
discovered that instead of having a flat washer, I was entirely 
missing the rubber seal! ( http://specialtauto.com/delorean-
parts/images/fuel-prim-pressure-reg-plun.jpg ) So while my hot start 
has essentially gone away, my car is out of tune. For the time being, 
I've disconnected the LAMBDA probe, and I've tuned the motor by ear 
(a litte rich, I can feel). I'm going to try the idea mentioned, of 
shoving a washer in, to wedge the air flow meter, and turn the CO 
screw until the fuel injector cracks. If that works, great! If not, 
then it's off to the mechanic, so I can hook up to his exhaust gas 
analyzer.

As an added bonus, I fixed my front mail seal leak. The breather was 
clogged with gunk. So I pulled out the mesh/chain mail inside, 
dropped it into some chem dip (dissolving everything withing a 
minute), reassembled, and shoved back in. No more excess crankcase 
pressure, and no more leak!

One of the biggest tools that I had help me, that I would reccomend 
to anyone performing a water pump replacement or any other work is 
simple: Sharpie marker & baggies. Pull it off, shove it in a bag, and 
label it. A digital camera, and masking tape can help too. But I 
didn't rely on them as much as I thought I would.

Thanks to everyone here who helped me out with their knowlege. I do 
appriciate it! I now have a car that doesn't need a weekly coolant 
refil (only recently became that bad), and starts instantly (almost)! 
And, I feel much more relieved that not only have I replaced the 
hoses and waterpump, but that I have now completed the task itself!

Thanks again!
