Andy A Posted December 2, 2023 Share Posted December 2, 2023 The car was given to me by my Son with a load knocking noise from the rear of the engine. I replaced the chain and tensioner only to find that when the engine was turned by hand the intake cam would play catch-up with a slap noise. I replaced the cam adjuster on the exhaust cam with a third party one and this problem was solved. So I thought. I purchased an Obdeleven scan tool and got following. block 91 and 93 are below. Engine up to temp. Block 91 Engine speed 720rpm camshaft adjustment intake bank 1 5.9% camshaft adjustment intake b1 (specified) 28.00KW camshaft adjustment intake b1 (actual) 27.00kw to 27.50KW Block 93 Engine speed 720rpm Engine load 15.5% Phase position bank 1 intake -13.00KW (It is -15.00KW when cold). Engine sounds ok. Reading is way off. I have dissembled and doubled checked all my marks on the chain, the cam adjuster and the intake cam sprocket. Everything is dead on correct. I will attach a pic of the cam lobs. Do they look about right? Thanks Quote Link to comment Share on other sites More sharing options...
