jremi21 Posted October 27, 2008 Share Posted October 27, 2008 Hi guys, My es300 is leaking oil. At first I thought it might be the power steering pump since it's dripping off there but some further investigation showed oil clearly leaking from around the valve cover gasket and possibly the cylinder head gaskets. I had my mechanic check it out and he said it's pretty common for es300s to develop these leaks. So he retourqed the nuts which were pretty loose but it still seems to be leaking but I'm not sure if it might be coming from a different spot. I guess I've got to get under there and clean it up to see where the oil is coming from now. Has anyone else had similar issues? Are there any other areas that tend to leak? It's not the oil pan gasket. I've already checked it out. Thanks, JR Quote Link to comment Share on other sites More sharing options...
djspawn00 Posted October 27, 2008 Share Posted October 27, 2008 Its probably still the VCG, its pretty simple to change. Clean up everything to help find the flow. Quote Link to comment Share on other sites More sharing options...

Yeah, I guess cleaning it up to find the leak is the next step. The VCG is easy to change with out removing the engine? Quote Link to comment Share on other sites More sharing options...
SRA Posted October 27, 2008 Share Posted October 27, 2008 I recently had to change the valve cover gaskets VCG on my 1993 ES 300. The rear bank is a pain, you will have to take off the air intake on the 1993, not sure if its the same on the 97. Its not difficult to do just a pain on the rear bank. I also changed the PCV valve and its grommet and hose. I would recommend putting TOYOTA parts from my past experience with the same parts. Also I later found an article here or on ClubLexus with another solution to this problem, if you use the search feature you will see that this is a common problem. Hope this helps.

SRA Posted October 27, 2008 Share Posted October 27, 2008 I just remembered, when I replaced the VCG, i needed a new set of spark plug gaskets (6 of them) and I had to drive to the dealership again just to get these. You may want to have a set of these handy just in case. Quote Link to comment Share on other sites More sharing options...

At first i was relatively sure that it was the front main, but the leak came on pretty suddenly, and was fairly severe. (dropped about a quart of oil in the driveway from letting the car warm up in the morning)... upon closer inspection... and i do mean close... i found that it was the oil pressure switch. The way i finally got to the bottom of it was to remove the right tire, remove the splash shield (2 bolts)... and then squirted brake clean on the drenched mess.... I gently hit it with an air hose to dry everything off, and had my wife start it up while i was ready with a mechanics mirror and a flashlight. It wasnt easy to see in that spot, but after running just about a minute, it started running down the switch, and down the block to all of the places that were soaked. If anyone needs help with the tools needed for that sensor let me know... it was a pain to figure out what the SST (Special Service Tool) really was since it is so buried in a hole....

pmerryman Posted November 12, 2008 Share Posted November 12, 2008 If it is dripping off of the power steering pump area, you will probably need to repalce the rear valve cover gasket and rear cam seal. The rear cam seal is generally the cause of that condition, and is VERY common pn pre-'99 ES300's. Quote Link to comment Share on other sites More sharing options...
