Hello!

I've got a 2008 CX-7 that won't start. 2.4L turbo charged engine. 150K miles. Recently started making a loud noise noise after warmed up that sounded like exhaust leak. Was intermittent - wouldn't always do it. I know turbo seals are leaking but turbo works (or was working fine). Wife was driving and heard a loud noise (described by her as a grinding noise) and car died. It will turn over but won't start and makes strange noise while cranking that I've never heard before on any car. I took video showing timing chain through oil cap to verify chain hadn't broken. Can anyone tell me what is making the weird clicking noise while rolling over? Video can be seen here: . I do alot of my own car work but I'm not an engine guy. I suspect it's time to junk the car as it's not worth the cost of an engine replacement but I'm hoping someone can at least tell me what could cause this noise while cranking so I don't junk it over something stupid and relatively inexpensive to repair. Thanks for any help!

 

You need to pinpoint where the noise is actually coming from. Doesn't sound good.

You can scan for codes & see if anything pops up regarding cam timing.
