all the valves, tappers, springs are good and tight checked those when I did the valve cover gaskets. water pump is new and no noise from that. it was making the sound before the tranny and torque converter swapped. old tranny had a broken thrust washer and did 30,000km before it started grinning metal up in the tranny fluid.

 

You'll def need a mech stethoscope so you can find the true area were noise is from ..maybe disconnect one at a time your fuel injectors on drive side as you state noise is from that side see if leesons or could be a relay or solenoid . evap purg is on that side the abs is too ..maybe when cold spray some trans fluid in throttle to smoke it to see if its a exhaust leak or cracked manifold .thats somewhat sealing when warm from heat expansion?? ..

 

Found a pipe with a T and green screw cap. The other end not connected to anything. Under the fuse box there is a pipe with a spit in it and wonder it's suppose to be connected there and that is part of my weird tucking sound.

 

Isnt that the evap purge line .. on my 2000 its on the firewall to the left of brake booster and it should go to that evap solenoid as i had mentioned before. That line should trail down to the charcoal canister beside gastank..

 

Finally solved the tucking noise. It was the evap hose that popped off dew to the split in the line to the T connector with the green screw cap. I cut the end off with the split and had enough slack to connect it back up. No more tucking sound.
