89 240sx ka24e with "diesel effect"

[180sx]

I am trying to figure out what has happend with my car before i winter stored it. There is few problems i need to fix so i can start driving it :

1 i engine had broken timing guide, replaced with new timing kit , new headgasket seals . Car run pretty good, copression was 155-165 , bolted on custom turbo kit, threw in a new clutch, 2 days later i get this noise sorrie about the size but thats the only way i could record it:http://members.shaw.ca/uden/kae.avi

so far i figured there is mainly vibration on bottom end , no noise from timing chain, noise is present in gear or out of gear , only above 2000-2500rpm , and adjusting timing doesn't change anything so its 100% mechanical, i have 3" solid exhaust sustem running , so its not rattle of any sort from outside , its internall. i do not feel much vibe on the sides of the block/head , its minor vibe on the oil pan transmission area.

i am armed with thesioscope , torque wrench and extra ka head going to go change the lifters/rockers tonight and try to pin point the noise again,

when i changed the timing chain kit i never pulled the engine out to clean the oil pan , i run atf/oil mix 2 times after putting it back together before driving it and it was all good didn't find any chunks in oil or in filter,. but 2 weks later it started knocking, atf/and oil again no resault, thiker oil no help.

devious ka previos posts are telling me i may have spun a bearing becoue of plastic from the guides plugs up the crank oil passages.

or my crappy non oem timing kit skipped a tooth and now past 2500 rpm my valves are tapping the pistons.... any thoughts , input, things to check for , etc will be graetly apriciated , sorrie about the long post trying to fit all the info in...

and i dunno if its related by its been abit harder than ussual trying to start it -10C , i go storage 1nce a week to start it up.

It knocks when you start revving it but when you let off the gas it stops knocking.

I thought at first it was a rod knock but it sounds more higher of a pitch then mine sounded. I really don`t know on this one. Only thing I would try to do is narrow it down the problem. One way may be to take all the belts off and see if it makes that noise. Since you said it sounded like it was coming from the bottom of the pan you could remove it and see if you see any metal shavings in the pan.

If it were me and the problem was not resolved by removing your belts I would pull the motor and transmission out. It isn`t that hard and it would allow you to tear it down and see what the problem is.

DROPING THE PAN IS A *****..... thats why i am trying to see if anyone had the same problem....before diggin in ... pulling the motor and transmission will have to do i guess if lifters don't solve the problem. thanks for the input.
