Hey all,
This is actually in a 1998 FZJ105 with 330,000km but I though I would post it here as there are more 1fz-fe owners in this neck of the woods.
Backstory - Purchased a rough 105 and set out to do all the maintenance on it and bring it back to its former glory.
So far on the engine I have done: Air filter, fuel filter, plugs, oil/oil filter, belts.
Recently I noticed when revving under the hood there is a knocking sound that's really bad, so I have stopped driving it and waiting for some spare time to start narrowing down if I need to replace this engine or not.
I'll attach a video that is it at its worst, will be getting a stethoscope and have a listen around around.
Seems to be when accelerating, can't really hear it at idle. Interestingly the sound reduced when I retightened the belts ?!
I'm very hopeful that this isn't a main bearing or rod knock and possibly just a bunged pulley? My nephew had a very similar sound that turned out to be an aircon pulley.
Is it possible I used the wrong/too thin of an oil? I used valvoline Engine Armour 10w-30 and also added Morey's oil stabilizer once hearing the sound to see if that effected it.
I'll update my progress on here, first step is to remove the belts and see if the noise is there.
