Fumoto Drain Valve

The F-103 Fumoto Drain Valve that’s on my Nissan Xterra.

I remembered when I was browsing for mods for my Xterra I came across this object. I knew immediately that I had to buy it because it’ll make my oil change a breeze. No more jacking up the car, struggling taking the drain bolt off and making a mess. I can now just slide the oil pan under the car and just reach for the valve and open it. Here’s a list of pros and cons you should think of when buying a Fumoto Drain Valve.

Why you should buy it? I’ll include my personal experience.

  • Makes changing oil a breeze. I no longer need to jack up the car to get under and take the drain bolt off, I just put the oil pan under the car and just reach for the drain valve.
  • Well made quality with limited lifetime warranty. Never had an issue during my 10 years of ownership.
  • No need to buy or replace anymore crush washers.
  • Comes with a synthetic washer. I never needed to replace the washer, never had an issue or a leak after I installed it.
  • No mess, no need to worry about the oil splashing onto your hand when taking off the bolt and the ability to connect a hose to the tip.
  • Accidentally overfilled? Simple, just go under your car and open the valve and release some fluid.
  • Need to take a fluid sample? You can just open the valve to collect some sample instead of draining all of your fluid.

Downsides to a Fumoto Drain valve?

  • Not recommended for car with low clearance or if you offroad and constantly scrape the bottom of your car. The Fumoto Drain valve does hang a little lower on the oil drain valve so you do have a chance of it snagging on something.
  • Slower draining due to the reduced hole size. Not a big inconvenience, I’ll let it drain while take off my oil filter and do other maintenance.

Clear Silicone Paste

I drove around everywhere in town looking for clear silicone paste and unfortunately, no one locally sold any. Lots of people on youtube swear by clear silicone paste, and I was looking to apply it to a few areas such as sway rubber bushing and caliper pins. So I ordered it online.

3M 08946 Clear Silicone Paste 8 oz

What properties of silicone paste makes it so special?

  • Used for lubricating and preserving rubber parts
  • Does not swell or soften rubber compared to hydrocarbon based grease
  • Corrosion-inhibitor
  • Water Resistance

What application do people apply this to on cars?

  • Since it does not swell  or damage rubber. People apply it on window weatherstrips, o-rings and rubber bushings such as sway bushings to prevent wear.
  • Function as lubrication so apply it to plastics or rubber for tight fitting applications.
  • Functions as dielectric grease, apply it to the spark plug rubber boot. This help the rubber boot slide onto the spark plug, seals the rubber boot and preventing the rubber from being stuck onto the ceramic.
  • Helps install gaskets. Have difficulty making a gasket stay and seat in place? Apply some silicone paste, it has a sticky texture that acts as a lubricant and sealant to help with the installation.
  • Works amazing on caliper pins, prevents moisture, provides lubrication and prevents rubber swelling. Note: Make sure its silicone paste and not grease.
  • Makes installing and removing future light bulbs easy especially when they burn out and melt.

What are the downsides of Silicone paste?

  • Collects dust and dirt and then become abrasive, as a result it can wear down the rubber
  • Difficult to clean off because of its water resistant properties
  • Can clog injectors
  • On any surface that you are prepping to paint, paint will not adhere to silicone paste
  • Max of 400 degrees. Anything above 475 degrees it volatilizes.

Ford Triton 5.4 Liter 3 Valve Spark Plug Removal Issue

If replacing spark plug was a video game, this is the boss that appears before you.

Some cars spark plug replacement can be difficult, but on the Ford 5.4L 3V  this is considered the boss of all spark plug removal. These spark plugs are in Ford and Lincoln vehicles with V8 5.4 liters and 3 valve made between 2004 to 2008. Whenever I browse forums owners always brag about how they successfully remove all 8 spark plugs without any issue. Some owners joke around about how removing all 8 spark plugs without an incident unheard of.  When I researched about this spark plug issue, owners mentioned car repair shops charge up to $1,000 to replace the spark plugs just in case there’s any issues. So this spark plug issue sparked my interest.

 

What is the issue?

The main issue is the spark plug itself.

Here is what the spark plug looks like all intact and at its happiest.


The spark plug is composed of multiple pieces. So if you’re really unlucky multiple of these pieces can get detached and stuck in the cylinder head.

After doing research about the issue. I noticed that owners usually get the lower shell and insulator tip stuck in the cylinder head.

What’s the causes this?

The breakage happens when the lower shell develops carbon build up. It’ll seize the lower shell against the cylinder head.

Here’s what the spark plug looks like in a cylinder head.

Here’s a zoomed in picture of what it looks like close up. There’s a really small gap between the lower shell and cylinder head.

The recommended spark plug change interval is 100,000 miles so this gives it enough time to develop carbon build up in the gaps. The carbon build up will seize the lower shell against the cylinder head causing the breakage when attempting to remove the spark plug.

Reducing any catastrophe

Overtime people have developed methods to prevent any breakage. What’s interesting is that Ford recommends that you do not remove plugs from a hot or warm engine and use any power tools. But surprisingly owners have been having a high level of success removing the spark plugs when the engine is warm and with power tools.  While these methods aren’t guaranteed 100% success, these have been used by others that have helped them.

1.  Before taking off the spark plug, try adding additives in the fuel to help break and weaken up the carbon buildup. Such as Sea Foam, Chevron Fuel System Cleaner, Royal Purple Max-Clean Fuel System Cleaner.  If you want to be extra safe, you can cycle through two gas tanks with additives before changing your spark plugs.


2.  Using penetrating oil. Some owners have mentioned that hey use a penetrating oil such as WD-40, B’aster, or Liquid Wrench to help loosen the break up. They would spray some penetrating onto the plugs and then let it sit overnight.

 

 

 


 

3. Using an impact air tool to remove the spark plugs. The torque from the impact tool is suppose to help break up the grips of death from the carbon deposits. Some owners have claimed a high level success when removing the spark plugs.

 

 

4. Using a Spark Plug Remover Kit. Some companies have develop kits that is designed to prevent breakage. It does so by locking the plug porcelain core to the plug hex allow it to turn as one.

5. Lastly, remove the spark plugs when the engine is warm.

 

What happens if parts of the spark plug gets stuck?

Since this is a known issue lots of companies have made tools to help remove the broken spark plugs.

 

How to prevent this happening again?

Champion designed a spark plug that is one piece so the breakage won’t happen agian.

If you do opt to use the OEM spark plug then you can use nickel anti-seize on the lower shell to help with any future seize.
