hello,
I’m seeking some advice on a new noise that sounds like a lash adjuster/ lifter gone bad for the second time. To give you a bit of back story about 5 months ago I had a ticking noise coming from passenger valve cover. Upon research and some knowledge I have I took apart the valve cover and didn’t see anything out of the ordinary but figured it had to be a follower or lifter.
So with my 4.6 hitting 100k miles I decided to have my heads remachined and cleaned up to be like new, and at the same time I replaced the lifters and cam followers all the way around and put my bigger cams back in and redid all the seals and everything. Started her up and she ran fine, tune was a little weird at first but quickly everything was sounding good.
Fast forward now and today I discovered a louder “lifter” type noise from the same spot on the passenger side valve cover. With all new parts and the heads being completely done over could there potentially be a underlying issue I’m missing or not thinking of that someone with a lot of experience with this motor might know? Any help would be appreciated.
Also I’ve been having some issues with the start up on my mustang. Some times it will start fine other times it will just tick and not turn over unless jumpstarted. I tested the battery with an ohm reader and got 12.4v and tested the alternator and got 14.8v, once started it runs fine.
Any advice would be great if someone could point me in the right direction. Thank you!
