Customer Question

hello, I have a 2004 shogun 3.2did lwb, drove fine yesterday then came to it today and turned over very fast and didn't start. I stopped and it was recovered to my mechanics, he stripped the top end to check the chain, valves, cam etc. All ok. He manually turned the bottom crank pulley and it was free then as if something catching. He thinks it could be to do with the crankshaft pulley/woodruff key. Any ideas before its stripped.

Get him to remove the crank pulley as this is very common issue on the 4M41 engines .

May find the bottom crank woodruff has also failed and jumped teeth ,

Could mean bent valves have him check this also .

Sorry but looks bad if the woodruff has failed will need to remove the head and check .

good news is the block and pistons always win so you be okay here .

See if any rockers are bent ,this will be a sign of timing chain jumping .
