Thanks for the replies, I don't know what I should do at this point. I by no means have a serious knock and it only really exists at idle, it's just so annoying and I can't stand those noises. What should I do? My 5mge only has 125k on it , was recently apart and examined and looked really good internally, and runs like a champ. I think I just have a colgged lash adjuster that I picked up after a 1000 mile drive to West Virginia(should have changed the oil before I left instead of after I got there because I had 2100 on that oil before I left
Anyway, what should I do now? I've been told to drain a quart of oil, then put in a quart of ATF and run it for a little while and then change the oil right afterwards to try to unclog it. If that doesn't work, I guess I was going to try those other oil detergents, and if they fail to work, I guess it's on to more drastic measures like head work. That gets to be all or nothing then, and I want to go turbo anyway...so what the hell, why not 7mgte then?
82MKIILtype,
I really appreciate the offer, did you buy that head from Keith Emery? I was going to buy that!

Anyway, I don't really want to take the head apart, I'm not very mechanically inclined and don't have the space to get into that anyway living in an apartment without a garage right now, if anything I'd take my head to someone to rebuild or buy a rebuilt one from someone in the future. I wanted that rebuilt one for when I go 5mgte next summer.
What should I do to try to get rid of my slight knock? It usually doesn't knock at cold start, then I drive it in town and by the time I'm at work, it'll knock at idle, then stop knocking if I rev the engine to say 2000 rpms or so. It tends to knock more when warm than cold, and more at idle than at higher rpms. At this point it's inconsistent, but it definitely knocks at times. Again, any help is greatly appreciated.
