Noisy Cruiser

[CJF]

I put it in drive and rev the engine (with the brake all the way applied) and the noise is apparent.

Therefore not this:

My ujoints when they were done in my Chevy made a lot of ting noises might check those

Detonation of any significance only occurs under load.

This points even more to detonation.

Knock sensors
Knock sensor wires
Coolant temperature sensors
Properly adjusting timing.

1) No knock sensors.

2) Timing definitely need to be checked ASAP.

Spent 5 hours figuring out the nuanced process of timing a 3FE today and got it done. For what it’s worth, I purposely adjusted it way off to hear what real predetonation would sound like and I definitely heard it. Once i adjusted the timing properly, that sounds that i heard when i had it unadjusted was gone but it is still making the noise that i demonstrated in the video.

Here is a video demonstrating how the noise is present in drive but not in neutral.



My front right wheel seal just gave out so i need to take it to the shop soon anyways. But any more ideas? Or is it just completely normal and i’m only noticing it as of the past few months?

Can someone with a 3FE maybe do the same thing i did in the video above and see if theirs does it too?
@jonheld what do you think?

Mechanic says it’s normal/benign for an old land cruiser motor. That’s all

Cruiser mechanic? Heard a lot of bad advice and misdiagnosed issues from mechanics when it comes to these trucks

Only real Cruiser mechanic is crazy busy and won’t return my calls. The mechanic i use has a 300k mile FZJ80 and they work on a lot of them, so probably more qualified than many but I’m not sure. Just changed my oil and getting the old stuff analyzed, might point to something.

What's your location? Maybe some nearby Mudders could take a listen.
