Is the 06 timing chain tensioner hydraulic?
- Thread starter Fishtaco
- Start date
I posted a pic of my filter in a previous thread as Jerry B asked if my filter was anti drain back and it is the correct Ryco type.
It only started after my oil change to 10w 30 as recommended or I didnt notice it when I bought it. OP may have had Thicker oil or additives in it ?
can you have somebody start it up for you while you listen with a mechanics stethoscope? I don't hear a lot about chain rattle with these engines, but we hear about lifters all the time. My 99 did the same rattle on a warm startup just like a cold one, though when warm it seemed to go away more quickly. Still lasted at least 30 seconds though, and it was less of a random rattle and more a definite tap that corresponded with camshaft speed, and was heard loudest under the oil pan so there was pretty much zero doubt about it being in the region of the camshaft and lifters.
Your mileage seems premature for a worn timing chain. They generally outlast the rest of the engine, you just replace it while it's already apart for a rebuild/refresh.
Though I suppose since people almost ALWAYS replace the chain when they replace lifters, it's possible that the chain is what's fixing some of the noises instead of the lifters.
Bit hard to pinpoint as its so quick, longest the rattle has lasted is around 2 seconds.
Obviously not a common problem and doesnt sound anything like lifter tick, maybe its something as simple as the starter gear not returning fast enough and touching the ring gear? engine runs quiet there is no noises if I put it under load and It has got no worse in 7 months so it cant be major.

No start up rattle in 2 weeks after changing oil to Magnatec 10w-40 and putting on the expensive synthetic filter.
I can remember now I did not notice any noise before the oil change to high performance conventional 10w-30 soon after purchase so could have been a faulty filter allowing drain back? or too thin an oil?
High performance 10w-30 was all that was available at the time in 10w-30.
Maybe it just didn't like that particular oil?
