This problem just arrised recently, I had just replaced upper intake gaskets and plenum and car was running smooth for a few days then suddenly there was a clicking noise. The clicking noise is constant from the moment i start the car to the moment i turn it off. While driving the clicking noise gets much louder and whenever i stop the oil pressure drops drastically and constant chiming noise due to check gauges coming on. Does anyone have the slightest idea what the problem could be? My first reaction is oil pump is failing

Low oil pressure is a sign that your bottom end is shot. Some coolant probably got into the oil during the intake gaskets failure, or during the work. The clicking you hear are the rod bearings going out, causing the rods to bang around. Time to start looking for a new engine, sorry to say.

Did you do an oil change after the gasket replacement?

yea the oil was changed new filter put in, the reason i thought it was the oil pump was because we took the valve covers off and turned the car on for a little bit and it would spurt oil at intervals not constant

That'* because of the bearings. Pressure will be low, but will also fluctuate with the rotation of the bad rod bearing(*).
