On the other hand it may make installing the Doug Thorley headers a little easier. Taking off the air plenum, for me, was a challenge. If you've never done it before, just take a day to do it. It's not as easy as it looks. The coolant lines are an absolute PITA!! Link to comment Share on other sites More sharing options...
RainGoat Posted December 16, 2020 Share Posted December 16, 2020 That sounds alot like what happened to my engine - the ticking, not the secondary noise I hear. I was told probably lifters but when we got in we found 5 screws on the power valve missing & one of the butterfly valves had somehow ended up on top of another. Unfortunately, by this point they had pulled everything apart. The shop couldn’t find any of the screws & was hesitant to put it back together as we couldn’t say for sure we had fixed the problem. Ultimately, we put a JDM engine in as it was only $1,000. The whole experience was costly & traumatic. I wish I had pulled apart the intake & had it fixed & put back together first as I suspect my noise might have been that loose butterfly valve - sadly, it was at a shop & they had pulled everything apart so we were too deep into it to unwind easily. Huge regret on my part - plus, F Nissan for not notifying owners about the power valve problem-especially when they compensated CA owners & sent out TBs on Altimas & Sentras with the same problem.
