Hi,

I’m looking to replace the SCV with the new one but I noticed I have that part in the way. Anyone know what that is?

Hi Nik that part it the top of the injection pump .  What year is your 120 , because it is a matter of does it use the one SCV or does it use 2 SCVs that are red and green connectors   . The early 120s use the twin red and green SCVs .

Hey Tony,

Thanks!! It’s 2006 (56 plate) invincible.

[TONYCY11]

To change the SCV it is absolutely vital that no dust or dirt enter the injection pump when you remove the fuel pipe and SCV as it will likely cause damage  to the injectors and or injection pump as no filtration is available after the fuel pipe that comes from the fuel filter that must be removed  for access to be able to remove the SCV/s , best to use a unused paint brush around the area to brush away any dust and dirt as well wipe the area with clean rags and a final brush off with the paint brush to make sure no chance of contamination  ,    and when removing the SCV they usually need to wiggle them out as they can feel stuck in even though you have undone the 2   5mm allen bolts .

Thanks Tony. It’s a fairly difficult access but I’m looking to do it this week. Looks like mine only has the one SCV. I can see it’s still the original small one though.

Have you watched forby4 diesel on you tube on fitting the SCV to give you a better idea on fitting the updated longer SCV , I had to glue the O ring to the spacer that fits on to the pump end of the SCV because it is a very tight access and my hands were too big and I kept nudging it and the O ring  kept moving out of its grove and when pressing the pump on  top of the fuel filter to push fuel through I noticed it leaked at the injection side of the pump of the SCV ,  if you have big hands its a 1 hour job instead of 15 mins most folk take to fit  it. If you get stuck and need any advice just let me know and I will help where I can .

[TONYCY11]

Oh Nik I forgot to mention it is best to put rags under the SCV if like me you drop any of the new longer bolts that come with the new longer SCV because the one bolt that you have to fit to the  blind right side is very easy to drop and had me undoing the bash plates to find it , and it could even get lost forever if the bolt gets stuck in other parts of the engine bay that you can not see , a rag will save you a lot of hassle as well as catch any fuel that spills out when you remove the fuel pipe and the SCV .

I watched the 3 year old one he had and looked like he had a lot more space to maneuver.

Found the more recent one where it all looks as crammed together as mine https://youtu.be/6rLR1UFdkOM

Thanks for the tip re the rag!

[TONYCY11]

Mine was also crammed together that is why I said my hands felt too big and that it made it a fiddly job for me to fit , the gasket did not stay in place and dropped off when I removed the old SCV so I had to wipe dry the area of fuel and stick the gasket back on with the clear silicone  grease that you use the put on the O rings to stick to the spacer , but I had to put a tiny bit of  super  glue the O ring to the spacer side that fits to the gasket at the injection pump made a lot easier for me to fit the SCV coz my hands nudging the SCV when fitting caused the O ring to keep moving out of place because the grove in the spacer is very shallow so the O ring can easy move out of position despite putting clear silicone grease on it to stay in place , but all that was me in my 60s fitting the SCV  you being much younger will probably find it much less hassle fitting it .

All as Tony says really, very fiddly rather than a hard job, and make sure you use a rag as per Tony for any dropped bolts.
I used an old towel to cover a bigger area, and had a telescopic magnet on hand, rather than risk moving the towel by grabbing a dropped bolt
As my engine was none too clean from previous owner, I used brake cleaner and Tony's method of a paintbrush, then airline to blow all iclean and dry.
I cleaned a much bigger area than just around the scv, and as Tony states no *beep* allowed  at all, especially above it.
My biggest hurdle was releasing the clip to remove the connector, that took longer than the job in hand.
Thanks to Tony for info, and Karl for pics of that bloody clip, which is slightly to the back of connector, and wouldn't release.
Yep, silicone grease is your friend, it's a ridiculously shallow recess in the spacer and in my opinion too big for the O ring which needs to be centralised, and I used a smear of Hylomar to seal the gasket joint
Oh, and dont do what I did, in thinking that I was undoing the rear bolt done by feel only - I unscrewed a similar bolt from the pump, unseen, then wondered why the scv wouldn't come off.
No harm done, but it meant I then had to get the bolt back by feel before re tightening, then get at the proper one.
After all that malarkey, the scv went back easy with no dramas with the bolts.
Good luck with it.

Telescopic magnet sounds like a good shout! I’m going to get that before starting on this to make my life easier since I’m prone to knocking things out of place  

[Tractionman]

I've had it years, very handy for awkward places, and about 15" - 18" long extended. Just like a car ariel with a strong magnet on the end.
Too strong sometimes if near the engine or other large lump of metal, but does the job, even when you can't see the object - just go fishing ! 😀

[TONYCY11]

Your right there Tractionman I have 2 of them and they have a habit of attaching themselves to other metal parts of the engine when you are trying to pickup a dropped nut/bolt the magnets are that strong 😃 . but they are worth their weight in gold for retrieving metal things that you drop in awkward places not just for cars but for any job around the house like  inside  washing machines .

[Tractionman]

Washing machine - have Toyota diversified, as they are discontinuing the Landcruiser brand. 🤷‍♂️😀

Yep, as we know, they are exceptionally strong Tony, a good workshop tool, and will pull items in even when not actually touching them.
I had a bench out on the grass in the Summer, I was using it to put a new cable on the old workshop hair dryer, and dropped 2 tiny screws which would have needed x ray vusion to find. I used the telescopic magnet in a sweeping motion like a metal detectot and it found and grabbed them up easily.

The hair dryer is not for me, I havent got enough hair these days, I use it for heat shrink tube, it's gentler than a small flame or heat gun.

Strange how these threads drift off topic, innit ?? 🤣
