    Short lived but sounds like knock. Video inside

    I knew what I was getting into when I bought another 20 year old turbo car. So, any recommendations? Appears to only knock like that at idle for the time being, only started this morning. Been on the lowest boost setting for the last few months, oil is good, pressure has been high all winter though I was told it was normal. Anyone looking for a project GTiR? I can't have 2 engine builds at once at 2 different houses (as I have to also buy a new Murano, what lukc), not enough tools.

    Anyway, I'm guessing is rod knock but it goes away when not idling.

    Dunno how to post videos properly since the new server change (photobucket) but here's a link.

            Yea at first I thought maybe exhaust leak but thats tough. Use a screw driver and start puting your ear to it, will magnify the sound for ya to narrow it down.

              If the bearings have just started to wear out than the oil pressure wont drop right away.

                Pretty sure thats not rod knock. Its a random sound. Sounds like some thing is loose and Only hitting sometimes.

                  Yah, it's not consistent and is only at idle. Thought mayve it would be water pump or a lifter but I wont' know till I tear it apart..

                    Its only at idle... Does that engine have hydro lifters? Might me collaspte. And when you rev/ build up oil pressure it goes away

                      Does the car still have AC? My AC pump made a similar noise before it seized.

                        Turned out to the the alternator lower bolt getting loose and for whatever reason, it lightly knocked against the block every cycle (that's why it sounded like something in the block, so low). Found a nut and locktite'd it back on, hopefully that won't come loose again.

                            no kidding! I'm glad I don't need to build 2 engines at once lol.

                            This car might become my auto cross beast since I'm most likely going to be too scared to break my delicate and expensive gtr...
