Got around to changing the valve cover this weekend. Starting to get fast at taking the turbo and VC off quickly lol. Hopefully don't have to take it off anytime soon. Got some new ngk 97506 plugs as well and gaped them to .22. Seemed to do the trick. No more smoking. I let it idle all the way to operating temps with no smoke at all. No codes popped up. Couldn't take it out for a drive yet sadly. Still needs some new tires for the rear and then a alignment. In the mean time im going to clean up the engine bay because its looking pretty bad. Now to get the DP fix and get it registered so I can finally have it back as my daily. How have you guy's temps been with this heat? Here in Virginia Beach its been anywhere from 80 to 110 degrees and I sit in about 2 hours of traffic a day. Just a little worried about temps getting high while in traffic.

Need some help trying to figure this out. On start up there's a loud ticking, knocking, misfire or lifter sound. I don't know which one it is and just want some input on it. its goes away after about 2 minutes on start up so it seems to be a lifter but then I check codes and I have misfire in cyl 1 and 3 or several. But I don't get misfires on all startups just every now and then.

Just the usual culprits 29CD, 29CF, and 29CC through the jb4 app, and sometimes I get shadow codes through mhd 2FCA and 2FDA. I've looked up the shadow codes and I think I read that its something with the ekp module and the voltage. Before I go replacing the module I was going to replace the voltage regulator. I took mine off today and it looks one of the leads is short and worn out and wearing out unevenly. I have no clue if that's how its suppose to wear out at all though. I just recently cleaned all the injectors and replaced the seals and decouplers as well to see if that would work but it didn't. I'm already planning to get some new index 12 injectors, PR ign kit and fuel pumps but I just want to find out this problem before I throw another 500 into it and it actually be a motor problem instead. Looking at my past codes its been cyl 1 and 3 for awhile now. I've swapped coils plenty of times now and it just stays with the same cyl. Could it be injectors causing this sound?

Put your finger on the fuel lines leading from the injectors and see if you can "feel" the ticking through the line. If you can feel ticking then your injector is bad. I had 2 misfires on my last dyno run and could feel a distinct difference in my number 2 and 6 lines. Replaced injectors and problem solved.

For you single turbo guys out there. What oil feed fitting to the turbo have you used? My vibrant 90 degree one is leaking out the threads and onto the blanket and then smoking and I cant get it any tighter. I got it as tight as I could go without stripping the threads. Have you guys used high temp teflon tape or some loctite?
