AYB280 0 Report post Posted February 24, 2007 Id say it would be sticking hydraulic lifters, the same thing happened with my car, just started ticking one day. Try doing an oil change, if your lucky the flush will remove any sludge causing them to stick. Quote Share this post Link to post Share on other sites

kerrynzl 3 Report post Posted February 28, 2007 Oil change it TWICE, the first time with cheap 'thin' oil and some engine flush [the crud has to go somewhere,and engine flush doesn't work too good in sludge] Then put the good oil in This works on Subaru's [so does a crusher!] Quote Share this post Link to post Share on other sites
