Reengineered rear valve cover??

Have you seen the video in post #79? It outlines just about everything.
removing the rear 2 bolts for the intake manifold support mentioned in post #85 were the hardest.
I think you should be able to do this job. Take extra care in separating and labeling the vac hoses and take pictures as you go.
The gaskets can be had cheap from rockauto. I used the Fel-pro gaskets.
tools i used
10, 12, 14mm sockets
1/4" torque wrench , 3/8 torque wrench
flat head screwdriver - for wire harness clips
needle nose pliers- for hose clamps

i used rtv on the sharp angles of the gasket When you pull off the old gasket, you can see where the factory did the same. Clean all the mating surfaces before applying sealant and the new gasket.

This says it all... You shouldn't attempt to DIY this.
If you have to "find" the intake manifold, then please do not attempt to do this job.
I don't mean to be harsh, but I'm not sure how I can phrase it any nicer. My apologizes if I offend you, but just trying to make sure you don't find yourself in a pickle.

Thats what i thought. if memory serves me correct; usually whenever you replace gaskets of any sort no matter what its for just about; then usually a least a little rtv in certain places needs to be used to "seal" it fully.

hyper let me also say i should have worded my post a lot better. I didnt mean "find" intake manifold. Im actually not totally sure what i meant at that point lol but yes i know what the intake manifold is and what it looks like so that should not be a issue. The only thing here is this just looks very time consuming; but if it has to be done at some point then it has to be done. But for right now Im just gonna keep checking the oil level every so often and will keep an eye on it and if i start to notice oil loss and i dont see anything leaking underneath; them Im gonna probably think that its either burning oil excessively or something in which case i probably will have to do the cover mod.
Remember, this valve cover "issue" doesn't affect all RX300's. It has only affected a handful (on this forum).

Well; thats reassuring at this point to know that it doesnt affect all 300s.(I think). I just hope mine is not one of the ones that is affected. Like i said before; for now all i can about do is keep an eye on things and hopefully things will stay good the way they are right now with no issues for a long long time yet.

Hyper; salim; or anyone else; how will i be able to tell at some point whether or not i really need to do that valve cover mod? By looking for leaks and checking the oil level regularly to make sure im not burning any excess etc?

Also; what is the correct part numbers for the valve cover and the gasket(the newer designed cover not the old one). Is this the correct part number for the newer valve cover: 112020A051? Got this number off of rockauto.com thanks matt

Since you asked me, I would say I dont see any harm in changing.

Just my opinion ,,, but I am still not convinced that the problem of oil consumption is due to original valve cover. There is a separate thread ... oil in the intake. Since the subject matter was getting too hot, I am pacing it down intentionally. I have always said that the issue is 'my lack of understanding'.

Well; since salim said he said there is probably no harm in doing the change over to the newer one; i do need to know what the correct part number(s) are for the cover and the gasket. And on this note; would i have to change out the pcv valve as well since the valve cover is slightly different than the original design and if so what are the correct part numbers for all 3 or 4 of the needed parts including the last part which i believe is the hose if im not mistaken? I tried looking for the cover on rockauto.com but they only had one part listed and that was out of stock at the present time. So i then looked up on parts.com and they have 2 listed; one for the right and one for the left valve covers. Am i right in saying the right valve cover would be the rear one which is the one that would need to be changed out?
thanks to everyone on here for taking the time to answer my ?s and for being patient with me. It really gives me a better idea of what i do and dont need, etc.

If you want to save a few bucks and reseal your front valve cover at the same time, get the felpro valve cover gasket kit VS50588R. It comes with front and rear valve cover gaskets and new spark plug tube seals.
Also, although the OEM pcv hose is convenient, you can choose to use a half foot of 3/8 power steering hose which cost about a dollar at any auto store.

You actually quoted all of the parts with the correct part numbers you need in post #92.

I think for me; the bottom line here is that since I dont have any current oil consumption issues at the moment; Im just gonna leave it alone the way it is for right now cause I have no issues as of yet(thank goodness). So; unless i see a pattern of something happening, etc; then Im not gonna order the parts needed. I mean yea it wouldnt hurt things to tear into it and replace the rear cover and reseal the front one by replacing the gasket for the front valve cover as well. But i think the biggest issue it sounds like i will encounter is getting the bolts for that bracket out so i can be able to lift the intake manifold up and out of place. Does this sound like it should be right as far as those 2 bolts go; and is there any real "easy" way per say to remove both of them; or are they in such a position that they are nearly impossible to get to? I do know that for some people it is easier when you remove the wipers and then take the windshield cowl off.

Valve cover replacement on 1999 RX300
I just changed the PCV Valve before heading home form the east coast and still used 2 quarts of oil (about 1100 miles).
I do not have any oil leaks or blue exhaust smoke and car runs fine. There is some oil residue on the rear cover around PCV valve.
So, my question is - Can you replace valve cover with updated replacement cover on 1999 RX300? Does it all fit properly?
Thanks in advance for your feedback!
