Random tune-up post

I have been having some trouble with the "station car", a 98 v6 mustang with 124k on the clock. Just hard starting. I know it's fuel related so I ordered a new pump and filler neck gasket. Since the weather is super cold installing that is on hold. I decided it was time for a tune-up so I order plugs wires and a new coil. I installed everything and immediately the car had a misfire. Rather then mess with finding spark, I grabbed the digital thermometer and tested the exhaust manifold and found #1 and #2 were cold. Switched the plugs on the coil and all was happy. 

The wires were old but passable, the plugs were terrible, rusted on the outside and worn to a gap of .7 - .8 when they should be .54 stock. The coil when heat soaked in the summer would stumble at idle.

Now it still starts hard but I know its either the pump of an "in tank line" that has a tiny split so the fuel pressure declines over a half an hour.   

Now we need a 40 degree day to get under it and drop the tank/ oil change. (say that as snow is forecasted for the next 2 days)

Flywheel, clutch, bell housing and some other details

Image
Installed the new flywheel.  Installed the new clutch.  Installed the clutch fork and throw out bearing  And then the bell housing  Installed a new transmission tailshaft seal.  I built a sled to drag it into place under the car and there's a bolt that fits the center of my jack through the center board. I may have to pull the shift cause there's exactly 19 inches under the pinch weld and thats the same to the shifter nub.

power steering rack line seals

Image
I finally decided to stop the leak that leaves a ton of fluid on my garage floor. I ordered the maximum motorsports rack seal kit. The instructions say you need to be clean before applying the sealant to the threads. I drained the rack and purged the rack after the lines were off so I could get rid of that little bit of fluid in the ports. i decided to completely remove and flush the lines to install the nylon seals. And have them stay clean through the install. the old one was chewed and the one that looks like new, wasn't installed right. Used the 2 screw driver method to gently stretch the rings out.  Then of course I take a break and get COVID. So 2 days later I am posting the pics.

water pump redo

Image
So with the change in temperature at the beginning of the year the water pump started sleeping when it was cold. This gradually got worse through the heat cycles. With corrosion evident on the bottom of the pump I decided to redo the water pump even though I am sure it could have just been resealed and been ok. I think I made 3 mistakes last time. I used the crap black gaskets that came with the pump. I used ultra grey rtv. I sealed the inner air pockets inside the pump. These filled with fluid and with the thermal expansion compromised the gasket. I went for a motorcraft pump this time as well as the light blue permatex rtv 22071. After I heatcycle the motor a few times I am going to go back and torque everything again. I also replaced the 2 left bolts that had corrosion on the from last time, with stainless ones. (5/16 - 18 4") I would have liked a 3 7/8" bolt but it's not available in stainless locally. I put a cut in an old bolt and chased the
