Question about Vehicle Parts & Accessories
I take it that the 'ticking' noise disappears shortly after the engine is started?
Can you identify where the ticking noise is coming from?
There are 2 noises associated with engine wear:
1. A rumble or 'knock' - maybe a 'tapping - ' noise from the bottom of the engine may indicate that the big end bearings are worn. The knock/tapping noise is caused by the worn big end bearings striking the crankshaft. The noise will often disappear after start up because of the oil finding its way into the space between the big end bearing and crankshaft. A rumble/knock/tapping from the bottom of the engine usually indicates a very major repair in the not too distant future..
2. A ticking noise from the top of the engine suggests a worn camshaft/cam followers or cam shells (bearings) .. usually a worn camshaft.
I'm not familiar with your model of vehicle (I'm in the UK). However, I would add that 'big end failure' isn't anywhere near as common as it was way back in the 70s. I would guess that your ticking noise has something to do with the camshaft. Any half-decent workshop would be able to diagnose the problem within a couple of minutes.
It's a relatively quick and easy job to change an overhead camshaft (I'm guessing your vehicle is overhead cam..). You may have to open your wallet and part with some of your hard earned dollars to join the 'replacement camshaft club' .. Worn camshafts aren't too uncommon.
