braveheartBG Posted December 25, 2014 Share Posted December 25, 2014 Hi guys, Just bought a 96 ,GTB with engine noise. When it's cold the car runs like diesel. I made two videos cold start and worm : Warm : and Cold : Any idea what is making the noise on warm engine? Sounds like hydraulic lifter . When reving the engine I cannot hear it when the rpm's fall.

monkeyposeur Posted December 25, 2014 Share Posted December 25, 2014 That doesn't sound like hydraulic lifter tick to me. I took a video of lifter tick: Yours sounds more like a rod knock or piston slap. Link to comment Share on other sites More sharing options...
braveheartBG Posted December 28, 2014 Author Share Posted December 28, 2014 I found that the intake hose between the turbos and the manifold is cracked and I hear whistling sounds from there.I read that this may cause detonations . Is it possible that this noise is somehow related to the other problem ? Link to comment Share on other sites More sharing options...
braveheartBG Posted January 19, 2015 Author Share Posted January 19, 2015 Hi Guys , I've started a rebuild of this engine- two of the pistons are in very bad shape which is causing the noise: Here is a pic. of the damage : http://media.snimka.bg/s1/4235/034713813.jpg?r=0 Link to comment Share on other sites More sharing options...
