95 Maxima SE Concerns

I have a 95 Maxima SE that I bought about a month ago. The car runs and drives great. I just have a couple concerns about it. The first thing is that the engine ticks. I had people tell me it was the injectors, but I really don't think that is what it is. The tick gets louder as the rpm increases, so that is why I don't think it is the injectors. I think it has something to do with the valves. I had compression done and I can't remember what it was, but it was good and it read the same all the way across the board. The other thing that concerns me is that when you start the car when it has been sitting overnight or for 4-5 hours, it puffs out smoke for a few seconds. I am pretty sure it is oil and I think it is valve seal related. Is there anything I can do to check this or confirm it. Would running a thicker weight oil help. It doesn't do it all the time and some mornings it won't do it at all. Other than that the car never blows any smoke. I am new to the Maxima world, so I was just curious if anybody had any ideas. Thanks.

i don't know about the smoke but that ticking is most likely a cracked exhaust manifold. expensive to replace but cheap to repair with good patches. it could also be worn vacuum hoses. it's most likely exhaust related.

the smoke may be a seal like you said.

The sound doesn't sound like a exhaust manifold leak. It sounds more like valvetrain, but I could be wrong. I was just looking for opinions. Thanks.

Odd, they are the most reliable cars ever. How many miles does
yours have?:eek:

121K miles. I mean the car runs great, so I don't know...
