Thanks, but actually I found a free PDF of the FSM on a toyota forum somewhere just searching google. Pretty cool, some guy has links to all toyota FSM's and was posting them all, now if I could find the link again for everybody else...*edit: here we go fellas, just click the little paw looking button to download (it's a torrent, so you will need something such as bitcomet to download), hope I can post this link http://daemon4x4.org...php?dcid=17&p=3

Ok so I found a free PDF online that contains most of the FSM for 2000 LS400, and under engine mechanical I found this. It shows the location, but I'm not certain if I have to remove the valve cover to get to it or not. I sure hope not. I am looking on page 5 of 6 or "EM-32" em-28.pdf here is the link to the torrent for full pdf download (I use bitcomet to download torrents) http://daemon4x4.org/portal/downloads.php?dcid=17&p=3

Thanks you guys.. awesome replies. I feel like I can do it now, especially with those pics on your flickr landar.

Well hey, thanks to both of you. I'm gonna go take another look today or tomorrow. So even though that diagram is for the 2JZ-GE, I'm going to assume it's in the same general vicinity? and hopefully it is as easy for me as it was for the mechanic.

I've cleaned the OCV itself, and my question was regarding the location of the filters, because I have no clue where they would be in regards to the OCV. did it take very long for your mechanic to clean the filters? were you charged a lot? I didn't want to start taking off timing covers and such unless I was doing the timing belt myself, and I might just go find somebody to clean the filters like you did if the job is reasonable.

surely somebody has removed the intake and lived to tell about it? LOL I just don't want to break anything, and if removing all the vacuum lines are necessary, well that sucks, but I'll still do it.

and hey, I'm glad to see somebody else got their problem sorted out. I'm almost there and keeping my fingers crossed. all help appreciated - I don't know what I'd do without lexus forums

So I took the time yesterday to pull out the LH/driver's side OCV and clean the part and port thoroughly with carb cleaner. I also found a vacuum leak coming from my intake box (the nipple had broken off) and fixed that as well. Code came back after about 20 minutes, so I went and got my codes read again, and I have successfully eliminated the misfires I was seeing (random & cylinders 1,3,5,7 - due to vacuum leak) so now the only code i STILL have is the infamous P1349. I am about to replace both OCV's to be safe, but I couldn't get the intake box off the top of the manifold without feeling like I was about to break something (I even started a thread to help me with the intake removal, dumb I know but better safe than sorry). Also, I always hear about the filters for the OCV and people replacing those along with the OCV itself. Is the filter easily accessible? I have yet to see exactly where it is located, and I figured I would replace it at the same time because it is very affordable. I just don't think I will bother until I do timing belt if it's deep in there.

So I have a quick question regarding the intake box on a 98 LS400. I removed the bolts holding everything down, do I have to remove the vacuum lines going to the big box looking thing to remove the intake? or does it come off in pieces? I have a 95 LS also and it seems way easier taking off the intake... I just don't want to break any of the vacuum nipples because I have already repaired one of them with black silicone sealant and don't want to have to do it again unless necessary.

Awesome! I've been hesitant to just getting out and cleaning them, I didn't want to waste my time and have to end up buying new ones afterwards.. so that's why I asked. That makes me feel a lot better, time to tackle this and clear my codes! I'm hoping they just need a good cleaning, but you never know.. she just turned over to 191,000 the other day. I'll come back and let you know how it goes. Thanks for the quick response Billy!

Hey Jarebear, have any success with just cleaning them? I recently got the P1349 and don't want to have to replace the parts if I don't have to, but I mean I will if I have to. Billy, do you recommend a specific cleaner? can I use brake cleaner or is that going to damage them?
