Help please! Ticking after Egr delete on 1kz-te (1 Viewer)

[bigmac10]

Hey everyone
I just got done deleting the Egr on my 1997 hilux surf with the 3.0td and factory inter cooler. I used the blockoff kit from vanlife northwest and installed an egt temp probe on the exhaust plate. I cleaned a ton of carbon buildup out of the intake manifold and intake ports. I bled the injector fuel lines by cracking them open at idle for a couple seconds.
The truck idles at 900rpm now instead of the 700 it used to be at.

Any help would be greatly appreciated, the truck was running great prior to the delete with no tick or anything.

Link to video of sound is below

I'm not sure how the EGR kit works. So it has a blanking plate at the rear of the exhaust manifold where the return pipe comes out of but everything else stays in place? Or that plate sits in somewhere where the return pipe comes back into the intake side? Can you put your hand on different components until you can feel where the mechanical ticking is happening to narrow it down?

Also in your video, it sounded like the ticking went away after a few seconds? Maybe you need to just take it for a good drive and allow the computer to readjust itself?

There’s a blockoff plate and gasket on both the intake and exhaust manifold and the return pipe and egr valve and vacuum solenoid have been removed. The ticking definitely is coming from the top of the motor, but hard to pinpoint exactly where. The ticking goes away when I roll off the throttle and is the loudest when I roll on.

Does the car drive a bit sluggish? Engine light on the dash? It sounds a bit like the timings out (retarded). Are you able to pull any diagnostic codes?

I've been having this pain in the ass issue with my timing control valve on the injector pump. Broken/damaged wires, broken connector, pins in the socket not making good contact in the new connector, leaking fluids getting into the connector bla bla bla. The result is engine ticking, limp mode type performance and I get an error code P1220 (timing control valve). I know it sounds unrelated but it takes less than a minute to check and rule out. Coming in from under the front left wheel arch, you should have access to the bottom side of the injector pump. You'll see two wires going to a plug/socket at the rear of the pump. Check those wires for any damage first. Then with engine idling, try pushing the plug into the socket or wiggling it and see if the ticking goes away or changes tone. I'd be interested to hear the results or this.

This sounds like an exhaust leak to me to be honest. I'm assuming that since you last posted on this almost a year ago that you got this figured out?

Air in one of the injection lines might do it too, maybe try bleeding them again.

Yes a year onward I hope this has been solved, hope the OP comes back and lets us know what it was.
