    Roof box with Prinsu

    Thule Sonic XL has a flat bottom and the pinch claws ride fully below the Prinsu crossbars. More support overall than a standard two-crossbar rack so should be able to load it up fairly well.

    Walnuts under the valve cover?

    Sewing this up. Had the water pump and timing belt replaced. 15,000 miles earlier than the 90k due date. No more walnuts. Here’s the old water pump. I’m calling this puzzle solved.

    Walnuts under the valve cover?

    Yeah, the sound is most detectable when I listen directly to the water inlet housing assembly. So I'm assuming right now it's the water pump pulley on the timing belt. All the drive belt pulleys feel and sound ok, except I think I'm detecting the noise coming from the drive belt idler pulley...

    Walnuts under the valve cover?

    Ok my thought about the idler pulley has changed. I drove about 150 miles yesterday and then parked the LC on cement instead of the dirt. This morning I noticed coolant on the slab. Pulled the skid plate off and found coolant dripping from below the crankcase pulley and the coolant reservoir was...

    Walnuts under the valve cover?

    I haven't pulled the serpentine belt yet but I did put a long, thin piece of rebar to my ear and held it against all the drive belt components. Everything sounded smooth except the idler pulley. I looked at the maintenance log (previous owner was pretty meticulous with his spreadsheet) of what...

    Walnuts under the valve cover?

    Regarding assumptions. VC gasket was done, then noise started about 7k miles later. I’ve known the mechanic for 25 years so would assume to trust him. I will pull the serpentine belt and check components for loose acorns. I’m so curious if someone has heard this noise before 😁

    Walnuts under the valve cover?

    Hi folks, new here with my 1999 Land Cruiser with 277k miles. Bought it with about 270k miles. Previously owned by a pilot who kept a hand-drawn spreadsheet of maintenance items. Lived its life in Arizona so no rust! I had a mechanic replace the valve cover gasket and the throttle body so far...
