After listening to the noise again on my way to work..I am thinking it could be the lifters indeed? It's very similar in sound to the noise heard after hard auto-x runs but that noise is the kind that subsides after the oil has flowed or been topped up. Hrmm. I might as well just try that Lubro Moly stuff as well when I am at it. Freshened injectors - Used ignition wires - Lubro Moly - Redline SL 1. 4 weapons for this little battle

One thing I have notices, regardless of oil is that after an oil change, especially if I waited to long since the last one, the lifters will start ticking on startup again, but after a couple hundred miles after the chainge it stops.

Ahh welcome me to the ticking club

I Just picked up another m42 recently and it's got the infamous tick. I am running 20w50 Castrol GTX in it and of all m42s I had, this is by FAR the noisiest :rolleyes:

Look out... Your motor is about to grenade!!! :eek:

Just kidding...

Some of it is definitely gonna be from worn lifters. They start to get a little concave over time, still functioning just fine, but get noisy. Injectors can be ticky as well.

Now, say you replace them with new ones, which are convex. Does this mean you get a little more lift (or rather get back the little you lost due to the tops dishing)? A little food for thought.

Had the same tick myself. sounded like injector noise, then it sounded like lifter noise! sometimes it went away then came back later, drove me crazy for a month! It started to get louder in the timing case(complete rebuild 2yrs ago). put in new tensioner to no avail. got worried about the front plate breaking again, so i tore the front case apart to have a look. After kicking myself in the balls, i grabbed the water pump by the shaft, and felt some play! The pump was put in the same time i rebuilt the front case, so i never considerd this a problem! I gave the shaft a spin and found the prick, i mean tick! (noise) All this could have been avoided if i would have removed the belt first and checked for play in the pump shaft!
I think the sound changed position due to the temp, oil visc. alum. parts etc... My dad always told me to check the the small things before going in deep. I guess i should have, he can't be wrong all the time, Right?
This might not be everybodys problem, but it only takes a few min. to check! Good luck with the prick, i mean tick!
