Going 10 mph. running the dog on the beach truck stopped running,I it turned over twice to start , no go, stopped imiediately and looked over engine , no spark at cap and rotor. Rotor not turning. been 90000 miles since re done belt ( timing ) , Timing belt broke hugh ?? I think so and hope I didn't ruinn the engine did I bend all the Valves ?? $$$$ ugh !!!! any help to answering this on a football sunday would be great thanks a million.
Well, I hate to inform you of this, but all Nissan engines except the V-6 that was used in the Quest mini-van up to 2003 are interference engines- meaning that if a valve is fully open and the corresponding piston travels to Top Dead Center (TDC), they will contact forcefully resulting in a bent valve.
I have seen this many times as most people don't want to spend the $500 to have their timing belt replaced.
Fortunately for you, Nissan cylinder head castings are built pretty strong. I have pulled the cylinder heads and replaced bent valves (be sure to "lap them in" with a good valve lapping compound) and reassembled the engines with fantastic results. Most engines have broken valve guides and valves and pistons, but Nissans typically don't break these things.
This is a very involved job and should not be attempted unless you have pretty extensive experience with the internal combustion engine, so I would recommend a trusted mechanic or, ultimately, your local dealer.
Depending on labor rate, you're looking in the ball park of $1500 for this repair.
I hope this has been helpful!!
