I have three problems I need to work out after I finished my stock rebuild on my D16Y8. Rebuild consisted of a re-ring kit, all new bearings, honed cylinders, lapped the valves, and all new tune-up related parts. First problem is my car idles really low after it gets warm and usually wants to die. I thought about messing with the idle adjustment screw, but why would it be different from before? It seems that there must be a bigger problem. Second, it takes a little longer than normal to start the car when cold. It's like it doesn't have the fuel readily available and takes a few seconds to get it where it needs to be. Last, and most importantly I have a noise coming from the t-belt cover. The best way to describe it is a "whir-whir-whir" noise. It almost sounds like something rubbing on the cover, but I took the cover loose and had no change. It is also quiet when the engine is first started up, then after a minute or so it starts. I also noticed antifreeze coming from the cover. My guess is I have a bad water pump (I may be the lucky one to get a bad new pump.) Will the pulley bearing make this sort of noise when bad? Or maybe the noise is something else and I just have a leak around water pump seal? What do you think?
