thanks carguy07 and code58
I shopped around for some quotes to get the valve cover off ..
Dealership wants $1150 for labor + parts (upwards of $550). Not gonna hapen.
Called PepBoys - guy quoted me $540 (labor + parts), This guy also reccomends an oil flush @ $89
Another garage quoted $550/- (Labor + only gasket to be changed).
They amount to almost 10% of the car cost.
I estimate that my car would fetch only about $6k.
Are these prices reasonable or should I be shopping some more ...

How about the removing the front valve cover and the engine pan?
By the angle the rear valve cover may be a better place to check, but the above two should give you enough info to pursue or not.

code58 - Thanks for the transmission fluid as a type of flush info. It's nice to hear ACTUAL experience about using this.
Lexus2K2 - If you were close enough I would too help out with the valve cover. Front cover is extremely easy to take a quick peak at the engine condition!
What ever happen to the days of neighbor helping each other out over a 24-Pack?

thanks for the offers - code58 and JohnLX300
I have not worked with Automobiles ever - so the fear.
I do get my hand dirty quite often. I like to build furniture (not from scratch) .. but assemble them. I have worked on many construction projects (small).
Given the proper direction I could probably do it myself. Anyone have any pics for the RX300 on which bolts I have to remove.
Pre-steps (like clean the engine outside first – with WD40 maybe)
Remove the engine oil
Which nuts/bolts to remove
How to remove the Gasket and replace it ..
I have found a couple of posts that talk about the removal of the Front valve cover (not RX but a Lexus)
https://www.clublexus.com/forums/es3...nspection.html
I like to get into Auto - but dont have a mentor. And I dont want to break my ride.

If you can build stuff, then get hold of Workshop manual. Lexus manuals are very complete.

The valve cover is mentioned under two sections :
1) EM–4 VALVE CLEARANCE
2) AX–9 VALVE BODY ASSEMBLY
I am thinking I should follow the AX-9 to remove the front valve cover. I should do Step 1, 2 and 3. Or should I go all the way to Step 11.
And of course remove the oil pan for inspection.
On a side note - I got the RX300 inspected by another garage. And got them to change my PCV valve. The old one was not too bad - it still had a rattle in it. Although not as defined as the new one. The mechanic did not find any visible leakage. And no visible smoke (the shed was very close to my house so engine was relatively cold).
At this point the next steps is to get the front valve cover off – either myself or the mechanic. Hoping to work on it in the next few days.

Another must have is
Reader's Digest Complete Car Care Manual [Hardcover]
to get you a high level overview.
Invest in a (or two low-range and high range) torque wrench (does not need to be high priced one).
Tip:
Do the maintenance, but never try to fix something that is not broken.
So when you look at the procedures, stop at the stage that says how to remove valve cover.

+1 on taking the front cover off yourself.
A basic set of tools - 3/8" sockets, ratchet, extension - will set you back from $15 to $50, depending on the quality level of the tools, and any quality level is sufficient for this job.
The main concern I have for someone completely unfamiliar is, tendency to over-tighten the cover and do it out of proper criss crosss sequence, which can tweak it, pinch the gasket and cause a leak of oil onto the exhaust manifold. Which is an obvious and easy to fix issue.
P.S. While the valve cover is off I would especially carefully examine the valve stems. You may have an oil seep along the stems, although that really should manifest itself in an emissions test with the scale of oil loss you are describing. But with the valves opened up I would take a look anyway.

Great info Salim - thanks.
For anyone who wants to get the book .. it is available at Amazon. Make sure you check the item condition - I kinda overlooked it and purchased a "Good" condition book. Planning to return and re-purchase a "New" or "Like New" condition - if the i dont like the condition on the one I get. Fairly inexpensive.
PaulDaisy - thanks for the info. Finally going getting to get my hands greasy .. Need all the support.
Good tip/reminder on the tightening of the screws. We should do it like we do for the wheels - opposite ones until all are done.

I don't know much about sludge, but I'm sympathetic to your disappearing oil problem. My daughter's 99 uses about that much oil on the highway, not so much in town. We got it several years ago with 115K miles. I believe it was maintained well, and I switched to Mobil 1 oil. It has been suggested on this board that if I switch to Pennzoil Platinum, my oil consumption may decrease. I plan to do that at the next oil change. I also was going to replace the PCV valve. I took one with me along with some tools (less that 7" long to carry on the plane!!) when I visited my daughter at college. Unfortunately, the dealer sold me the wrong (thread-in vs.push-in) PCV valve, so I'll have to do it later.
Just thought I'd share. Hopefully, different oil will help me. I really don't want to have a sludge problem....

No sludge, just heavy varnish.
What type of oil are you running?
+1, on running PP 5W-30, it will help reduce consumption while cleaning up the engine.
If switching over to PP doesn't change consumption then I would look into the revised valve cover:https://www.clublexus.com/forums/rx-...lve-cover.html

what are next steps ?
trhs75 - after I started this thread - I started to monitor my oil consumption. And as like in your case - I am losing more oil on long trips (more than a couple of hours on the Interstate). Less in town. I would say the 1Quart for every 750 on Long trips. And 1Quart for every 1000 miles in-town. I have changed the PCV valve. The mechanic says car is fine. No visible oil leaks.
hypervish - will start using PP from next oil change. Thanks for the tip.
overall it is good news. No sludge (my biggest fear) from inspecting the front valve covers. Would not think that front and rear would be different.
At this time I plan to just keep monitoring the oil levels and top up as needed. Not sure if I need to take any extra steps.
