[bfmv]

HEY GUYS I HAVE A 1984 HILUX WITH A 3L DIESEL ENGINE IN IT

I TOOK A TRIP TO COAST TODAY AND ON THE WAY BACK A TICKING NOISE ACCURED IN THE ENGINE I PULLED OVER AND IT WAS STILL THERE AT IDLE WHEN I GAVE THE ENGINE A REV IT GOT LOUDER AND FASTER THEN SLOWER AGAIN AS THE REVS SLOWED

THE NOISE SOUNDS TO ME THAT IT IS COMING FROM THE TOP END OF THE ENGINE IM NEW TO HILUX UTES SO ANY HELP WOULD BE GREAT

THANKS IN ADVANCE

How many kms? Is it quiter when the engine is cold but gets louder as it warms up? It may have spun a big end bearing.

thanks for your reply mate

thats what i was thinking, umm yer i think it does when i pulled up it idled then started to shake and rattle but then went back to the ticking then did the same thing again the hilux has nearly 300'000 on the clock but the motor is out of a later model i didn't put it in so unsure of how many ks on it

I have the 3.0L diesel 5L engine in my 99 lux, and i Had these same noises, but it happened after I blew the engine, it was making big end sounds but it was really running bad already...Take it to a mechanic and show them, where abouts do you live?

[Willy Hilux]

Might have jumped a tooth on the timming belt. I had the tensioner bearing fail on mine and the outer sheild of the bearing came adrift and went around the timing belt causing it to jump a tooth or too.

I've got the exact same sound but the engine still drives normally... Don't know what it is either...

It could also be a blown exhaust gasket or cracked manifold.
