Took the BOV screw and bottomed it out. This should effectively render it "shut"
No, that doesn't keep it shut, it just raises the opening pressure to 14 psi or so. To keep it shut you need to pull the adjuster, drop in a spacer and then tighten the adjuster down on the spacer.
Its like hes a newb again

I'm interested in finding out what is causing the issues.

I am a 1.6 TD newb. I went straight from my first diesel being a 1.6 NA to a year later dropping in the 1.9 TDI with a manual boost controller on the waste gate line. The k03 has never had a problem building boost.. I have more power out of my TDI than this 1.6 when I pop my friggan boost hoses off!!

I can't help because I don't know anything but I just went out to daily drive my 82 truck that I have been working on for months. I got it timed to 1.04, stock fuel settings with k24 turbo and stock exhaust/downpipe.
The engine was non turbo and ran just fine since I had the car for over a year before putting it into truck
Td Injectors were from something else I had running that I left on the shelf assuming they were good like I remembered.
Injection pump with lock collar still on and cleaned/resealed, stock lda/fuel screw, etc.
Looks like 2 injector bodies are leaking which I don't remember. Also fuel bubbling from where the threads are.
Engine runs like caca compared to my stock setup 79 rabbit with open exhaust. And worse than any other td motor I have had in any chasis. When I stomp on it its letting out a cloud of grey and not reacting fastly on boost gage. Like a few seconds held down and I see a few psi.
Also I thought I was nuts but the revs are hanging when I let off the pedal for a couple seconds then dropping back down to proper idle. Can reproduce that in the engine bay with the throttle arm snapping back to idle position.
I am actually scared to go out and drive it on the highway but will later and see if I can even build boost to stock bov levels.
My impression was to turn the fuel screw down but the power delivery just isn't right to begin with. I'm wondering if my injectors are jacked up and want to replace them.

To keep it shut you need to pull the adjuster, drop in a spacer and then tighten the adjuster down on the spacer.
Bottoming the spring out doesn't hold it closed? Jeez.
ok, so like a small socket or something? It did increase the mid RPM performance though.

Results! Awesome. Happy to hear that cranking down the screw on the bov made a difference. It's clear that there are other issues including still losing pressure through the bov.

You want more bottom end - change turbo! That dinosour K24 does not have bottom end...

but it still won't have bottom end then because he still hasn't disabled the blow off valve haha

Did you ever get around of this?
Same thing happening to me on a stock QSW TD... BOV blocked shut, wastegate blocked shut, still can't get it past 4-5psi...

Wastegate is probably stuck open. Kkk turbos get stuck a lot

thats just how it goes... k24 on 1.6... i had a 1.6 with k14 and k24 on the 1.6, k24 is too big for 1.6 so on low rpm's doesnt do anything... even with the screw all in... mine only worked after 3000rpm... now i'm runing on a 1.9 tdi ref AFN with the same k24 and its awesome... its like the 1.6 doesnt have enough air to move a k24 properly at low rpms... if you wanna run fast with a 1.6 just trow in a k14... but it will run well just until 4500rpm after that looses power... to go beyond that go for k24... lets say ... i saw my 1.6 pass 5000rpm with the k24... but lets face it... its not healthy... i didnt like it...
also did you rid of the discharger on the admission?

While the K24 is outdated if you have an unrestrictive exhaust it will spool fine.

I assume QSW is Quantum Syncro Wagon? I've seen quite a few 1.6TD Quantums but never a TD QSW. I didn't think that any of the Quantum Syncros ever came with a diesel option. Are you in North America?

thats right a good exaust will also help to build boost especially on low rpm's... but its the same setup that i had before and i had the same thing... and the 1.9 there is no problem with that because sends much more air to the exaust so spools the turbo much better... if i kept with the 1.6 i would put in a k14 no doubt about it... and a friend of mine is about to do the same mistake... i had told him but he wants the big one lol he will have issues on low rpm... his problem not mine...
