Been slow progress but I wanted to send an update. Oil pressure seems good. Its around 20psi during idle. I also fixed the down pipe exhaust leak (noise is still the same). Next I am going to do a compressions test and then check timing. Again thank you all for your help

I bought a car stethoscope to do that. Hoping to have time this weekend to troubleshoot.

The car did not always make this sound. My first step is to find out where the smoke is coming from. In case you missed it here is what I did to the engine while it was out of the car Engine Work done: new fuel injectors oil pan gasket lashed valves replaced EGR new oil filter rear main seal pilot bushing

Bunch of questions to answer: Zed: The procedure I was using was to turn the engine until the lobe was pointing up, Adjust clearance. Turn engine again and adjust the next one. I then re-did the same procedure the other day and the engine sounded better than the first time I ran it. Clicking was still there ETI4K: I am also curious as to why there is so much smoke and where it is coming from. I did not remove the intake or exhaust manifolds when the engine was out. I had 3 studs break where the exhaust manifold connects to the down pipe. I thought I repaired them correctly. I will re-do a compression test and see if the numbers are different from before I pulled the engine Patcon: I am getting a mechanical oil pressure gauge today to confirm pressure. I put 4 1/2 quarts of this oil in - Lucas Oil LUC10679 10679 10W-30 Petroleum Oil

I forgot to mention. I removed the spark plugs one by one yesterday and the sound did not change.

Thanks Racer X. I have those gauges as well

Thanks, Captain. I replaced the injectors so it is possible these are louder. The engine definitely sounds better now that the I re-adjusted the valves. I will have to do it while it is hot next. I think, as you said, next step is to fix exhaust leak. Thanks for the help. Without this forum I would never be at this point and so close

Some more info and pics. I have an exhaust leak as I see smoke. I cant tell if it is from the exhaust down pipe connection or possible the connection that leads to the EGR. Not sure if this is a separate issue.

if it is ticking then it needs to be tighter, correct?
-
Rust Advice 78 280z
I checked all the valves. I few of them were too tight as you guys mentioned. Here is the new video. It sounds much better but I am still getting that clicking noise. vlc-record-2021-05-31-19h26m06s-IMG_3625.mp4-.mp4

It has to be a mistake by me. I thought I adjusted them all correctly when I had the engine out. Guess not
-
Rust Advice 78 280z
fingers crossed! Will check tonight. To double check a cold engine Intake is .20 and Exhaust is .24?

After work today I am going to open it up and see what I find.

Rust Advice 78 280z
right, I didn't touch those as they engine was running fine before removal

Rust Advice 78 280z
I forgot the gasket between the exhaust manifold and the down pipe. While unbolting I broke a stud. uggghh! Waiting for new studs to come in now. Will lash the valves in the meantime.
-
Rust Advice 78 280z
I did lash the valves before I put the engine back in but I will check again. As Zed Head suggested - here is the current situation All the structural damage has been professionally repaired. Engine ran fine before removal. I did a compression test and it looked good. Engine Work done: new fuel injectors oil pan gasket lashed valves replaced EGR new oil filter rear main seal pilot bushing new master cylinder for clutch and brakes Transmission: clutch fork pivot ball throw out bearing new fly wheel and clutch Suspension: full rebuild of front suspension rebuild of brakes new wheel bearings new hubs

Reading somewhere that this might be an exhaust leak. Is that possible. I do have some white smoke
-
Rust Advice 78 280z
Well, I was able to start the engine which is a great thing....but now it sounds like this. Where do I start troubleshooting? IMG_3607.mp4

makes sense, thanks grannyknot

Rust Advice 78 280z
I am assuming that it will still work if deleted but not be as safe, correct? Can anyone help with question 2 and 3 in the previous post
