Noisy Lifters Should I Use Different Oil Weight?

    Got a little lifter chatter going on now in the cold weather. Is this normal for Ztec 2.0? Should I change the weight of the oil to help with a little chatter. Its got 140,300 miles on my 2000 Zx2. Any ideas?

    Forgot to mention my zx2 doesn't get driven every day. Its been known to sit a few days before driving it.

    Lifter clatter with a car that doesnt get driven each day doesnt seem too bad. I dont think a different type or viscosity of oil will help much. An oil/filter change might - for a while. You could try changing lifters, rotating a new one into each position, till you eliminated the one that has a sticking relief valve or whatever. Mine are all 1.9L, where its much easier to swap a lifter.

    Is it hard to rotate lifters. Any videos on how to do that on the zx2

    What are you running now?
    Cold weight? (0W, 5W, 10W?)
    Hot weight? (20, 30?)
    Brand? (Pennzoil, Valvoline?)
    Type? (mineral, part-synthetic, synthetic)

    I found a service bulleton Article TSB 02-1-9 saying it is safe to use 5W20 and that Ford recommends 5W20 viscosity grade oil for service. But then I hear from some ZX2 owers that 5W20 is to thick and you get the clatter in your valves. Its spring here in the Midwest so Temperatures are changing so I guess my viscosity will change to.

    Thinner is better for something that does a lot of sitting because it flows quicker. Synthetic tends to be even thinner.

    However you're in Missouri and we approaching the warmer season. While thinner is better for cold start, it may not be optimal for hot engines.

    Basically you'll have to tweak and test.

    Noise when cold, go lower on the first number. Noise when hot, go higher on the second number. Though the numbers are the same on the bottles, different brands seem to have different "feels". You don't have to go full 5W-30 or full 10W-30... you can mix. During the Winters for example on my 2nd Gen 'scort, I'd be full 5W-30 Castrol mineral. During the Summers I'd mix up to 50%, 10W-30. The ears "see" what the eyes cannot. I tried part-synthetic, same brand and viscosities but the engine was louder, (because it was thinner,) so went back.

    Try priming the lubrication system prior to start and see whether that has any impact. This merely involves holding the accelerator pedal to the floor, before beginning and during the crank. Max of eight seconds cranking shouldn't stress the starter too much. Two cranks of that length should be more than enough to prime. Doing that would eliminate the brief moment of lifter clatter I'd get after an oil change or long sit. This feature was originally meant for clearing a flooded engine by turning off the injectors during the crank.

    My 00 zx2 has been ticking and clatter since I got it at 225 k and used 5w 30. And it’s still going at 335k. It goes away when it’s hot. The noise might be from the flat tappet lifters by the cams. But it’s most likely not going to be an easy fix. Some have done the VCT assembly on the exhaust cam and seen it work.

    So just play with oil weights? What weight should I try first?

    Like Denisond3, I would've also suggested inspecting the lifters as it's absolutely cake on the SOHC 1.9L engines. Looks like that involves pulling the cams on the Zetec engine though. I'm going to guess that it probably uses "buckets" instead of the hydraulic roller lifters that the SOHC 1.9L uses. If that's the case, adjusting valve lash is a time consuming procedure.

    Without getting ridiculous in terms of getting far away from manufacturer specification, tweaking the oil weight is what you're left with. If that doesn't totally resolve it, then you'll have to pull the cams.

    The ZX2 uses buckets, not hydraulic lifters.

    What oil weight do you guys recommend here in the mid west as we approching warmer weather. Im running 5-30 mobil 5000

    Start with manufacturer oil weight and mix in heavier stuff as the ears so deem. It's been like two decades, but personally did not like Valvoline and Pennzoil... stuff was like water; thins out way too quick.

    Remove the valve cover and check the gap between the bucket and the cam lobe (high point of lobe away from the bucket), .004 to .007 for the intake and .010 to .013 for the exhaust cam. Of course you will need feeler gauges and an 18mm wrench to turn the crank nut...

    I would sketch the buckets and write down on each your measurement for each.
