M35 Stagea Ticking Sound

[Forssan]

Anyone have a clue on what it could be?

Just bought the car, didnt tick when i inspected it, started after i got home...

Car has an idle issue, ive changed the spark plugs and rocker cover gaskets so far, soon i'll be changing the two coil packs i tested with the multi that were out of ohm range.

Only thing im thinking is sticky valves/lifters/rockers as the car runs fine regardless of the noise and only ticks at idle or low rpm.

Sounds really bad though, especially when you turn it off, makes a bad clacking sound.

Any help or advice will be much appreciated, thanks.

Sounds awful. 

Fan hitting the shroud

Bearing gone on one if the pulleys.

Loose timing or cam chain slapping around (pray its not that)

The sound of a damaged hydraulic lifter would be alot faster.

Good luck

It does sound awful, i am thinking timing or cam chain as you said.

Ive tried to get it looked at a few times though no ones wants to touch a jap import. 

Anyway, i'll see how i go on some others and hope it's not too bad in the engine.

How'd you go with that ticking noise???

I think mine has started to do the same so if you figured out what it was any info would be great, thanks mate

Still havent sorted it sorry mate.

The sound hasnt gotten any worse, ive taken it to a jdm mechanic who has rebuilt these engines before and he said that it doesnt sound metallic so wouldnt be a cylinder, in the head etc and sounds like the vct/timing chain. All a money factor and worth factor atm.

Had a similar sound (not as loud or violent) from a dud RB25 Neo VCT unit.

I hope it will be the same. I'll have one more attempt at trying to fix it before i hand it over to someone more mechanically minded then me.
