Your plan was what I was going to do originally - check it; refit if fine; repair if broke. But after finding out there's an upgrade part (I didn't know about it until I wrote this thread and got other member's input!), I figure even if it LOOKS fine, the relatively low cost of the upgrade parts (costed me about $85 AUD to order which is probably less than what gets spent on a week of groceries for my wife and I over here in Aus) and the simple procedure, it just didn't make sense not to upgrade the parts as it appears that it's essentially a FIX for a known weakness/problem. At least for me personally, it would mean there's one less thing that I'll need to keep an eye on which in my books, is totally worth.

M54 checking DISA valve (need to replace seals?)
Anyone know what the pots are for in the kit? Bought mine ages ago and finally found it... I’ve looked up instructions on website but can’t find reference to either lubricant? One is blue-ish and one brown-ish. Any insight? Cheers

That is exactly what I did. I can't even see how the pin has enough clearance to come out of the assembly and get sucked into the engine. I have a feeling that the fault is less common than people think

M54 checking DISA valve (need to replace seals?)
Well my parts arrived and I had some time this morning to started the procedure. In the middle of it right now.
GOOD thing I am doing this because...
My DISA valve is ffffff'ed!
- It's missing the O ring (im certain this motor is from a wreck now as the prev owner said).
- Pin is OK but the flap has 0 resistance on it
- Switched on Ignition (no engine start obviously) and the flap only moves about 10% of the way.
Going to begin the teardown/repair now. Hopefully it sorts it!
Update:
Unit looks fine - just the flap and rod/pin way too worn. I could move the rod/pin about 1/2mm in each direction! Upgrade parts going in!

All done now! Turns out my car DID have symptoms that I simply just got used to.
I found the car a bit sluggish before under 3k rpm but now, it's completely changed. Pulls strong from 2k onwards. I've also noticed that on start-up, I don't have the random shaky idle which I got used to resolving by putting enough gas to keep it at around 1.2k for a second or 2. Sometimes as well around the 3k mark I would have snappy on/off pull which I had always thought was just the way the engine ran. Totally not true. Smooth delivery now
Soooo glad you guys in this thread told me about the upgrade
Super gunky. Looks like (from my quick googling) that the crankshaft ventilation system needs a look at. Anyone know if this is a critical/urgent issue?
Comparing the old bits and the new. Good thing about the upgrade is even at it's worse case scenario (the aluminium rod loosens), nothing should fall into the motor - the valve just probably won't run smoothly which definitely soothes my paranoia. *Note the rod goes in from the other side - I just put it like this in the pic for comparisons sake.
If anyone is doing this upgrade, I would say that make sure you put enough grease on the parts and don't over tighten the rod. I went a bit ham and it actually hindered the flap's movement a little. It doensn't need a lot of force - especially if you're using loctite.

It actually looks like some one already did the upgrade on your valve. Stock valve have some sort of cap where the rod comes through.
I'm not spoilt! Its just a cheat code for NFS3 that stuck with me

Oh yeh Kev - if you look at the base of your flap, it has a deeper hexagon shape where the new alu turner part goes in. Lucky you! Also note the pattern on the flap is the same as my upgrade part. Yours is sorted already that's why I guess you felt it looked so solid

Any insight on my previous comment? The difference between the two grease pots that come with the kit?tomrdy wrote: ↑Thu Aug 16, 2018 7:50 am If anyone is doing this upgrade, I would say that make sure you put enough grease on the parts and don't over tighten the rod.

Sorry mate missed that! My kit only came with one pot. Which kit did you get? I noticed the kit from eBay/X8R had 2 pots of which one i think is the Loctite/threadlock. I just had some laying around at-home and used that.
Also for reference, I followed the install instructions from X8R (on YouTube).

Mine was just a clear tub - definitely was normal grease inside.
What does the contents look like in yours?

One has a light brown tinge, so normal grease. The other is blue
Edit:
Never mind. I think I've found it, it's lock-tight. The stuff I use isn't blue

Does the upgrade kit sort the flappyness? I've got maybe a cm play in mine. Also I think the diaphragm might be buggered. Should I just buy a new disa? And upgrade it?

The flappyness is probably the plastics starting to have play. Mine free-spun on the spot.
I would probably say try the upgrade/repair kit first - if it's fixed it's fixed. If it's not, then get a new disa and transfer the kit to it. Either way the kit is a good buy.
