Engine Noises?

[WishonaSR]

Ok well I have a few problems on my 1989 Maxima/Auto 163k1. When I start my car up(cold start) for the first 10 or so seconds the engine is rather noisy/clattery then it dies down...also it idles at above 1000 rpms for a little while too. Normal?2. Ocassionally during acceleration there is a raspy bees in a can sound that occurs briefly. I sounds as if there is and exhaust leak right in the back of the enging near the beginning of the y pipe. The exhaust is newly replaced by the previous owner but i am not sure if the quality of workmanship was up to par. Could it be a bad gasket or broken ex. man. studs?3.What would be the best way to fix a slipping auto trans?Thanks a whole bunch.Steve:D

Try adding some Trans-X to the transmission, its worth a shot.

Try changing your oil and using a diff weight oil.. what are yu using now ?

by doing this it will cure your noise on start up..

i think the noise being heard is posibly an exhaust leak and you have a flange gasket improperly seated. is this a j30 or u11 max? if its a j30 it could have a header pipe problem. pretty common on the body max. if its a u11 the 10 seconds of noise could be lifters not pumping up fast enough. try 5/30 and factory oil filter as a cheap method of checking it.

to solve ur #1, I have a similar noise, and its in part because my slack side guide is completely cracked in half and flapping off my timing chain, and because it take a moment for the chain to gather oil, the sound you hear is metal on metal, thats why when the chain gets oil, it dies down (thats my hypothesis anyway)

89 max doesnt have a chain. belt driven till 92 then the ve came out with the vg for 2 years then the vq became the only engine offered in the max from 95 on
