It gets worse.... I did some more searching at Z31.com. a FAQ about swapping in Maxima parts says the cool thing about a Maxima 3.0L is the getting valve covers in red. Guess what color my valve covers are? Red!
This engine overheats but only when it is pulling a load. It will run normal temps idling in the driveway, but take it out on the road, with the turbo pumping (you! clap!) up, it bubbles and boils up thru the overflow bottle. And now out the dash vents. I knew this when i bought it, but was hoping a new thermostat, hoses, belts, and radiator flush would fix it. I am going to pull the spark plugs to get an idea of what's going on in the combustion chambers.
Leaky heater core? Head gaskets maybe? I bought a gasket set, but won't invest much more than a top-end freshening in this engine. Priced a rebuilt VG 3L turbo a few day$ ago. $2,700. yikes.
She is starting to look more like a Hybrid 5.0 V8 swap candidate now. Uncharted ( or frozen ) waters - full steam ahead!
Those 5-bolt wheels still baffle me. Since this wasn't a turbo car originally, shouldn't an '84 have 4-bolt wheels? It has the small turbo scoop on the hood, but the hole in the hood sheet metal was obviously cut post-factory.
Well I still like it,
