    Has anyone used the Seafoam to clean out the lifters? As ive noticed, its kind of common for lifter noise on the 2nd Gen at high mileage. Although i do have the typical clatter, First thing in the morning ONLY when its cold and the truck is being driven (engine under pressure) It sounds like a really loud lifter. SO embarassing ive had to turn up the radio to tune it out. Especially having to pick up speed or getting up a steep hill first thing. Lasts for quite a few miles before it goes away when the truck is completely warmed up and been driven. Scares me because it sounds like something is broke, really bad. Other then that. it runs smooth and no noises otherwise. 112k miles on the 2007.

    LOTS of people have used seafoam to clean out their engines, and have been happy with the results.

    Using synthetic oil tends to help, especially when the issues are worse at start up/cold....an areas where cleaning alone won't help.

    Thanks. unfortunately i cant do that myself so would have to have the dealer do it for me. . oh, and by COLD. . .i mean cold weather. The colder it is outside, the louder and longer it takes to stop the noise

    Dealer to do WHAT or you?

    Change the oil, or suck seafaom into the vacuum line/pour some into the oil/gas?

    It SOUNDS like the synthetic oil change would be job #1.

    The seafoam treatment is really, really easy, just need another person to press the gas when you are pouring it in the vacuum line. The recommended treatment is one bottle spread out in 3
    1/3 for gas tank
    1/3 for in the oil crankcase
    1/3 for vacuum line

    I have done it using 2 bottles
    1/2 in crankcase
    1/2 in vacuum line

    1/2 in first gas tank
    1/2 in second gas tank

    Pouring it in the vacuum line has to be done really slow, you dont want to hydrolock your engine.

    Also, in addition to the seafoam treatment, you can use the spray version to spray your intake through the throttle body, this will ensure your intake is clean as doing it throught the vacuum covers mainly the left side of the engine's valves and intake.

    Gotta be careful spraying through the throttle body with the engine running. The computer doesn't like it whe it doesn't get a reading from the MAF sensor.

    I dont think the dealer will do it. Why dont you ask for anyone in your area for help, and you can meet some Xterra folks in the process.... I don't know how the dealer bills for this type of service but dont let them charge you more than 1 hr labor...

    Im not sure exactly. The dealer does it for me. Also, The Seafoam did not help. I did it the other day. Lifters still noisy. HERES THE THING. . .they only make noise when the weather is cold and engine hasnt warmed up. PLUS, its only when theres load on the engine. At idle or smooth cruising theres no noise. Just when i add acceleration such as going up a hill and picking up speed. Also, seems to make quite a bit rattle when letting off the gas after load. Like its from the exhaust valve. Its NOT preignition. I know that sound I get that every so often. Completely different sound. I have a feeling this is going to be a complete lifter replacement. ARGH!!!:meh:

    You are describing dino juice issues...and I know you said you used synthetic, but, it doesn't sound like it.

    Did YOU put in the oil, or, did you pay Jiffy Screwed, etc?

    :D

    @Tjtj....The dealer changes my oil. I ASSUME it's synthetic. I'll have to check now. Sheesh.
    @J Everett...it's not a rattle. It's a lifter sound. Sounds like engine is going to throw a rod.
    WAS WONDERING if the oil pump is going. But oil pressure guage shows normal all the time. .
