Question about 1985 Nissan 300ZX

2 Answers

I am thinking of weighing the option of keeping it or selling it

My silver 1985 Nissan 300ZX was perfect until the timing belt broke last week on my way home from work. Now it needs valvetrain repair. It's a 5 speed manual transmission, "non 2+2" 300ZX with t-tops.The car has 175,000 miles it. Air conditioning was recently overhauled and works very well. It has a new battery. Also now have replaced the water pump and timing belt. The digital dash is fully functional and fuel gauge sending unit is brand new & working perfectly. Can you help?

All you have to do is eithe replace the heads or just have yours rebuilt..the VG30E motor in these cars is what we call an interference engine which means when the timing belt broke the pistons made contact with the pistons and now they are bent which means they are not closing which means no compression

If you like the car, and the rest of its in excellent condition, then fix it.it its rusted under neath, paint bad, interior bad, then NO. try to find a low mileage newer engine. I dont know Nissan that well, but didnt the MAXIMA use thes same engine. if so, there a lot to choose from. a salvage yard should be able to tell you what engines will fit. I would get one from a MAXIMA if at all possible. older mature drivers, ect.

I am having a problem with my oil pressure... my guage which is not a dummy light, keeps dropping to like 1 kg per sq. inch when normally at 120kps i'm doing 3000rpm and the oil guage reads at around 3.7...


Don't get too concerned yet. Take it to the shop and let them scew in a well know mechanic's gage to make sure that the sensor isn't giving you a bad signal. That would be the first place to check.

Just broke timing belt on my 300zx,does thi


Yes your engine is a interference engine,
which mean valve to piston hit.

But replace the timing belt.
Possible you didn't bent a valve.
Depend on the condition when the T/B broke,

Let me know.....

Crank turns but timing belt won't


sounds like your timing belt tensioner isnt tight enough

Crank turns but timing belt gears won't


If when you try to start it, it turns over very fast, no compression, the valves are damaged.
You will not hear the pistons hitting the valves.
If the timing belt broke or the drive pulley on the crankshaft has sheared off then the engine is dead.
I do not believe this engine is a 'free wheel" design.( You can call a Nisan dealer to verify),
Once this happens the piston hit the Intake/exhaust valves and the repair cost will exceed the value of this old car. You may be able to sell it for parts or scrap metal or like I did, give it away to anyone who will tow it away. And of course never buy another car with a timing belt!

the timing belt should be changed every 60,000 miles.
your engine is an interference engine, which means if the timing belt breaks or skips, the valves will hit the pistons.
if your belt broke you will have bent valves. so the heads will need to come off and bent valves replaced.
