Another 1FZFE with Ticking Sound! 96 LX450 with 181,000 Miles (Video included)

A few years ago I picked up a couple of exact copies of the OEM knock sensor from O'Reillys for ~$40 each however that same part may not still be available.

Another busted Knock sensor connector

Recently found the #2 Knock sensor connector to have snapped off, the connector was just loosely hanging on the knock sensor, the tip off was an intermiitent loss of power. So the sensor connector piece was stuck inside the harness connector and after a few tries was unable to remove the stuck...

Rockauto sells an NTK brand sensor for ~$95.
NTK IME makes reliable products.

More Information for NTK ID0164

Thought I'd update for anyone else dealing with the knock sensor code. I ended up biting the bullet and ordering a genuine Toyota 89615-30050 from partsouq. It cost about $125 including shipping. No codes after about 300 miles of driving.

It should be noted that the 1FZ-FE engine requires qty 2 knock sensors. This is the case for my ‘97 engine that got two new sensors from T.

@Pin_Head The pictures might be deceiving. There were a few deep scratches and the oil pump gear had some scratches as well. I put the new bushing in this morning and the new gear fits just right.

Ran into another issue of course. As I was torqueing down the cylinder oil nozzle and check valves, the first 2 both broke at the weak point in the valve bolt body. This is incredibly frustrating because now I probably have to wait at least another week to get (6) of these in, and I can't really do much assembly without them. I needed to have the motor back in by next Sunday so that I could have a couple of weeks to break it in and line everything out before a trip in June.

Hey mate, I realise I am awakening an old thread but have just had the same thing happen with my oil check valve shearing off apon install. Did you get a parts number and aquire them from Toyota direct? Hard to find which unit is for the 1fz as all the ones I have found are listed for other motors.
Cheers!

Which "oil check valve" are you referring to (oil pressure sender/sensor, oil level sensor, pressure relief valve, or??)

To help find part numbers you can go to Partsouq and type in your VIN, then start searching for the system, part, etc.

Figured it out, it's the check valve/bolt for the piston oil nozzles. Local dealership wants $30 per unit, while Amayama have them for $10 each.

The reason I got this nailed is because I went through it. I know this noise all too well and why I chimed in to try and help the dude who put his face to the name.

My 1FZ-FE is a now 900 miles young, 100% OEM long block rebuild down to the lifters and even the shims. Every single part is new except the valve cover since NLA.

Unfortunately, I had to reopen up the engine to do a forensic analysis on what caused this noise to discover it was a nicked oil pump gear. All three gears replaced —> sewing machine smooth. I’m talking the tiniest of nicks that you cannot feel with a finger nail. I wouldn’t have believed it if I hadn’t seen it with my own .

This is not a valve train noise. It’s not a rod. It’s coming from one or two or three of the gears that sit behind the timing chain cover.

But disclaimer is my og engine and truck was a BaT type rig back when I bought it years ago. If the op went into this purchase mentally prepared for a rebuild, I honestly wouldn’t bother fielding inquiry from the ih8 peanut gallery and start getting to work on rebuild plans. Be discerning on where and with whom you seek counsel.

I don’t recommend to others the path I took. It’s a lot and it’s in some ways personal because the 80 is your baby/memories/community. I’ve already made my humble suggestions to the op here. He’ll do great if he has a solid rebuild plan and sticks to it.

So you did a complete rebuild and then had this noise, leading you to reopen and replace the crank & oil pump drive gears correct? I’m just wanting to clarify because I am in that boat. New OEM block and full rebuild, and have this exact same noise on startup. Noise is there with PS pump removed, leading me to believe it’s either the crank gear or oil pump gear as I reused those during my rebuild.

Obviously kicking myself, but just curious if your post here is the same situation I think I am in
