(92 nissan stanza) wont start; broken plastic near timing chain
I have a 92 nissan stanza(manual) and it doesnt start. it sounds like the engine is about to turn but it doesnt...the alternator seems fine and wen i took the valve cover off i found broken pieces of plastic all down the timing chain. big chunks. the distributor doesnt move and theres no spark comming from the 4 spark plug wire things..im down to fix it but i have NO clue wat the problem is..
Well you got that far, are you comfortable with replacing a timing chain & gears? Sounds like their shot, and that's why no distributor turning. If your not experienced it may be better to check around for a friend who is, or local shops for a price quote on repairs. Sorry, wish I had better news. Here's a link you may want to have a look at though. http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280099730

well the plastic piece are from the timing chain guides are either broken or ripped off,and the metal rattling was probably the timing chain,,i think the timing chain jmped or broke and broke the guides,if thats the car you most likely bent the valves in the head,,,i would remove the cam cover and the timing chain cover and see what you got,you may need a engine
It is probably not the timing chain but the tensioner and guides. The guides are some bakelite plastic ****. you need to take off a lot stuff, belts power steering, altenator pulleys timing case cover. Check the timing gears and chain for damage. Replace guides tensioner and any damaged parts. Disconnecting the front motor mounts you have raise and lower the front of engine with a hoist to gain access to the timing case. A long tedious job and hopefully your valves weren't damaged when the chain let loose if so the whole thing is just not worth it terry the pirate
