jnjdragracing Posted May 16, 2006 Share Posted May 16, 2006 Okay, I bought a 1984 300zx / 3.0 v6 engine. Good body etc, engine timming belt broke per a mechanic. Pulled it in the shop and took off the top timming cover and noticed the belt was stripped. Tried to remove the bottom cover and noticed I can turn the engine by hand with plugs in, not a good sign. However I am a small block chevy guy not a 300zx guy. Question any thoughts on the engine before I go further? I only paid $50.00 for the wholw car, my friend has a 86 300zx, which I was able to get the engine from complete, he said the guy he bought it from siad the engine was blown. The timming belt is in good shape. Question how easy are they to rebuild and are they worth it or should I just small block it? I was hoping my 300zx had a broke timming belt and I could just pull the heads and have then go through. Well since the engine spins so easy by hand with spark plugs still in, I am thinking maybe a broke crank? or just wore completly out. I was hoping to fix it up for my son. Any suggestions please, it is not a turbo..... Thanks John.... 1 Quote Link to comment Share on other sites More sharing options...
hoov100 Posted May 16, 2006 Share Posted May 16, 2006 might be that the exhaust valves are open? Quote Link to comment Share on other sites More sharing options...

The rear disk brakes and diffirential my brother wants, my friend next door want the rear brake lights / lens. All else goes, cheap parts plus shipping. Only have $50.00 in whole car. Only thing you will be paying for is labor for me taking off and shipping. PM me if intrested. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted May 16, 2006 Share Posted May 16, 2006 I bet the valves just bent. Not very likely that the crank or rods would have any damage. Pistons... maybe, but not likely. You could actually pick up another complete working engine for change and make the thing run again. Those engines are very low cost and when maintained will last forever. I have an 85 Turbo that I'm working on so if I need any parts I'll definitely let you know. Quote Link to comment Share on other sites More sharing options...

Guest ZFury Posted May 18, 2006 Share Posted May 18, 2006 What color is the interior? Quote Link to comment Share on other sites More sharing options...
ZR8ED Posted May 18, 2006 Share Posted May 18, 2006 Uh if the timing belt is broken, then the cams won't turn.. this leaves any valves..intake or exhaust that are open to remain open..no wonder it is easy to turn over... Sounds like its too late anyways..just thought I would comment anyways. Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted May 18, 2006 Author Share Posted May 18, 2006 Passenger fender is damaged. Looks like it was in a wreck. I will check on the rocker panel.
