Azplinker Posted April 14, 2015 Share Posted April 14, 2015 I've got a really bad noise at startup but it then fades to a ticking noise once it begins running. Can still drive but wondering if maybe a valve spring is broken. Is it possible to check if a valve spring is broken with out removing cam shaft? Can you just press on the lifter or is cam shaft removal the only way? Link to comment Share on other sites More sharing options...
jyeager Posted April 14, 2015 Share Posted April 14, 2015 I've got a really bad noise at startup but it then fades to a ticking noise once it begins running. Can still drive but wondering if maybe a valve spring is broken. Is it possible to check if a valve spring is broken with out removing cam shaft? Can you just press on the lifter or is cam shaft removal the only way? This engine has overhead cams. When you remove the valve cover you see the cam shaft, not to mention the valve springs. So it wouldn't even be necessary to press on a lifter, you would see it. The hydraulic lifters are a more common failure part than a valve spring and the valve spring breaking is usually more disruptive than you are describing. What you describe sounds to me like a bad lifter. The simplest test for a valve train related failure (valve, spring, lifter, rocker arm) is to run a compression test on your cylinders. Any cylinder with a valve train problem will show it on the compression test. To do that you only need to remove the spark plugs, which is probably easier than removing valve covers.

CNAM Posted April 14, 2015 Share Posted April 14, 2015 Sounds like it could be the timing chain. Or a tensioner. Link to comment Share on other sites More sharing options...

You can do that by posting the request in the thread, PM'ing a member of the Mod Team or by using the "Report" button under the first post. Please take more time to consider the best section for you questions and do not post the same questions all over the forum. 1 Link to comment Share on other sites More sharing options...
