Update: its running with a camshafter position sensor code. Think I installed the timing chain incorrectly. If i remember right I lined up the splines rather than timing marks...So I think all the noise is coming from the lifters

 

When you say splines, do you mean keyways? Hard to believe it's running at all in that condition. The timing would be considerably off, not to mention the valves wouldn't be closing properly and the compression reading would be affected. Interested to hear what you find out.

 

sounds good. Might have a look at the crankshaft sensor then. Thought I was being clever replacing it while everything was apart but may have gotten a bad one. I've read that can throw camshaft sensor codes.

It did drive for 5 miles or so with lifter ticking away and a rough idle.

Smoke is mostly gone now

Getting P0340.

Took it to the local shop to have them use their fancy scanner and it had:
"58 : Diagnostic Module Tank Leakage (DMTL) Heater Power stage
70 : Fault in camshaft sensor or valve timing
12 : Oxygen sensor upstream catalyst (Bank 2)"

 

Installed old crank sensor. Cleared codes. Verified cam sensor is plugged in and wiring looks good on first inspection.

Noise has been reduced down to just tappet/rocker assembly noise. Sounds very much so from the passenger rocker cover. Going to pull intake back off and get to the rocker cover tomorrow hopefully. Thinking that the rocker arm isn't getting oil (not so bad) or I have a bad tappet despite installing all new tappets. (this would be worse)

Edit: being too perfectionist. Rocker arms were degreased... Need to drive it I think

Yes I think at this point you should drive it and see how it shakes down

 

First drive with the previously known good crank sensor installed and P0340 came back. Drained the cheap break in oil I had (with lots of ZDDP additive), and pulled off the oil filter.

while I had the oil drained, I popped off the crank pulley and fan to pull out the Cam Position Sensor. Used electrical cleaner in the plugs and degreased the CPS with electrical cleaner. Voltage to CPS plug was nominal 12v. CPS was in good shape without any severe particulates on the magnet. Not sure there is a way to test the CPS itself Reset computer through UltraGauge.

On restart with new oil and cleaned sensor, starts a little rough (as since the rebuild) with timing at ~0deg with minimal fluctuation (+/-2deg or so). Once it drops RPM idle and goes to 15deg timing, P0340 immediately goes to pending and triggers ultra gauge alarm.

Im concerned the LOUD "tappet/rocker" noise is valves smacking the cylinders...Thoughts on that? At this point I think the only timing related thing would be the timing set I installed during the tear down and the CPS sensor itself. As previously stated, I have my concerns I may have lined up the keyways rather than the timing marks...It is certainly not getting quieter although it does get quieter once warm. Startup has consistently been loud

 

Pulled front cover today and found I did indeed line up the notches. Timing was probably 15° off. Hoping this didnt f up my freshly ground valves...time will tell. Should have it back together tomorrow.

 

ITS ALIVE AND QUIET!! I REPEAT IT IS ALIVE AND QUIET!!!!!

hopefully my valves arent destroyed...time will tell

 

I've been waiting for this update ! Kudos.
