SOURCE: rattling noise when cold start. noise dissapear

You problem is most likely just lifter noise. This is common with a lot of Ford engines with self adjusting lifters. Although lifter noise is bothersome it doesn't pose a serious problem. Unless your engine starts to miss or your gas mileage drops way off lifter noise is just an annoying problem.
I would recommend that you add some Sea Foam Engine Treatment($6-$8) to your oil. This is not an oil treatment it's more of an engine cleaner. If this works you'll need to add it every 2nd or 3rd oil change.
If this doesn't take care of the problem then depending on your engine you may have adjustable rockers that would allow you to remedy the problem. If not, your options are limited to living with it or replacing the lifters and possibly other valve train parts.

Does it have a carburetor or is it fuel injected? In 1986 it could be either way. It sounds like a carburetor with a choke problem.

this is by design. under load, the computer will deactivate the air conditioning in order to take the load of the compressor off of the engine, thereby getting more power for required acceleration. the a c light will remain illuminated etc, and after you finish accelerating the air conditioning will resume normal operation.

AT START UP THE ENGINE RATTELS FOR ABOUT 3 OR 4 SECONDS LIKE THERE IS NO OIL PRESSURE


This might be as simple as an oil filter draining down and delaying oil pressure during cold starts.Recomend usage of Nissan factory filters as theirs has a built in check valve to minimize bleed down.Also recomend oil no thicker than 5W30. You may be also faced with a hydralic lash adjuster bleeding down causing momentarily loose clearance in the valve rocker assembly. This particular ratlle would be half of crankshaft speed which would indicate upper end rattle.

A rattling noise from the engine bay


Check the heat shields on the exhaust system. They get loose from the extreme heat fluctuations work loose and rattle. Especially the one between the engine and firewall where the 02 sensor screws in. It probably rattles less after warm up because heat causes expansion which makes it tighter. Hope this helps.

Oil pressure high when engine cold. but fine when engine is warm


It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.
