Probably a bad injector and possibly a head gasket...how long have you had it and in what state did you buy it....either get rid of it..or order a jdm engine. As much as a love these cars...the injectors go if they haven't been replaced in the vicinity of 130k and the head gaskets seem to blow easily. I have had 6z's now...and have had ONE on the road...i cut the rest up for parts b/c they had so many issues. Let me know if you need parts....i'm scrapping on this week that's stripped except for the engine.

ive only had it for about a mounth. it was my friends car that i was helping him build. it just had a new RS crate engine put in, that was ready to go pretty much out the crate. when the engine place put it in they said it was normal but it doesnt sound right. he was tired of it and let me get it. dont think head gasket, not over heating now that i fixed a hose, and no water in my oil.
im not sure about my injectors, never checked them. i was thinking along the line of fuel pump or fuel pressure regulator.
if i were to have to order the engine about how much do they run, and what website would i need to go to for a good one.

I don't know if I'm just getting to old or loosing my mind or both but I don't know how in the world me got to scrapping an engine (or car) because it has a fuel leak. I'm not a car mechanic, but I have been a construction equipment mech for more than 40 yrs and during this time, I can count on one hand (maybe 1 1/2) that I've had to bring a car to another mech. If this car had a carburater, I would say have it rebuilt and thats it. BUT, its fuel injected, which I know almost nothing about but I do know this. There's very few places that can cause your crankcase to fill with fuel. If this was my car, I would buy the manual and just keep pulling components off until I found the one thats leaking, replace it and I'm done!!!! I bought my car ('86 n-t) a few months ago and the engine ran so poorly that the guy took $550.00 for the car. I started "sniffing" around and found that all of the injector connections were corroded. I spent less than $100.00 on the car, cleaned and re-insulated all the connections and now, you have to turn the radio down to hear if the engine is running. AND, if I want to have some fun, I can spin the wheels and wake up the whole neighborhood
Get some wrenches, get some advice, and fix the dam thing!!!!

bad electrical....you prob moved the grounds and wires enough to disrupt them....i had LOADS of issues with just moving wires around and making bad connections...try cleaning them up if it ran prior to the starter failing.

Hey Buc, this is Dave (engdocpro). I read that you've scrapped out some Zs. I've got an '86 n-t 2+2 and I'm looking for some parts on the cheep. #1 I need the two struts that hold the hood up. #2, I need 3 hub covers for the standard alloy wheels #3 I need the bottom leather and vinyl seat cover for the drivers side (has to be tan) and OEM #4, I need an Injector cooler relay, the one thats located under the side panel by the left rear seat #5, I need a r/s headlight lift motor (got to be working one) #6, I need the two little knobs that you push up to release the handle on "T" top. Also, any ideas on where to get OEM headliner material (tan). You can reach me at: engdoc39 hotmail.com Thanks

I own a 1986 turbo,I don't think you have a problem.At an idle the guage shows a vacuum of -7 as you hit the acellerater the throttle plate opens thus showing less vac between the plate and the intake,what you should find is that when driving this condition will be noticed as turbo spools and transitions from vac to boost.hope this helps.
