Took me around 50 hours total but I wasn't rushing. Seventeen years worth of dirt & grime don't come off willingly. DJSG3

Greets, Won't bore you with words just some pix to tell the story. The reason why and some before & after shots. It lives again!!! DJSG3

White smoke & moisture out of the exhaust means coolant is getting into the system and that most likely means a blown head gasket. If you have the tools and a manual to guide you it can be done. Just did it to a '93 myself. If the oil was milky that would mean you have a cracked block, yours isn't so just a blown head gasket would be my guess. For the power steering fluid, look for leaks at the pump and the fan and all the hoses in between. Hoses that drip at the very least need the clamp adjusted or changed. Make sure the clamp is right behind the bump at the end of the pipe and straight. If you do the HG job you might want also to replace the timing belt & water pump while you are in there. The hardest part of the whole job is getting the crank & cam pulleys off. Check my other posts for the tool I used to get the crank pulley off. For the cam pulleys, take off the valve/cam covers & grab the cam with a 24mm wrench. About half way down the cam there's a spot for it, looks like a big nut around the cam. DJSG3

Update: It's called a cam plug and it's made by Ishino, costs about $10 so replace it it is.

Might want to check your heater core also the a/c evap. drain hose may be either clogged or has been moved and is not draining out under the car but into the car. DJSG3

DJ That's the same pix I have, but not what is actually under the hood. The return hose from radiator comes off the bottom right (facing toward firewall), runs into a silvery tube that connects to a t-stat like housing that's attached to the block just below the right front tip of the intake manifold. I saw a similar one in the upullit today, think it's a 94 like mine, but the 92 I looked at had the tstat housing as in your picture. Anyone have experience w/ a set up like mine? Lexis I looked over at rockauto to see what kind of water pumps they have for your car and all of them are timing belt driven. Even if yours isn't, it would still need a belt attached to it to make it work. I've attached a pic of my pump. To get to it there is a metal plate you have to take off after you open up the timing belt cover. The pump is that shiny thing at the top, the coppery colored tube at the bottom is the crankshaft. The camshaft pulleys would be above & to either side of the pump. Just looked through a book I have and maybe your setup looks like picture #2? DJSG3

Greets, Anyone know if this part (see picture) should be sealed with some RTV or is it supposed to hold its own? It's leaking so I removed it and cleaned it, can't see any defects in it & so was wondering if some sealant is recommended or should it be replaced? Thanks, DJSG3

The water pump is behind the timing belt cover, the thermostat plugs into it.

Greets, Already posted this in another Lexus forum but for those that get around much here goes: Been reading in here and elsewhere about how to get that screw on the end of the crankshaft off. I keep seeing the one where you use the starter motor to loosen it, sounds good but how do you get it back on? Saw the official tool on Amazon (cheapest price I could find) and said, that's way too much for a one time job ($60). So went to Home Depot and bought a 1½" wide 3/16s" thick steel bar, a 1" metal hole saw and a couple of bolts, $20 total. Measured the hole pattern on the pulley, then created a template for drilling on the PC. Printed & cut it out of the page and then taped it to the bar. Cut the bar to size, drilled my holes, slid in the bolts & attached it to the pulley. Then I put the socket on the nut/screw, attached a breaker bar with a 20" extension to it. Supported that with a tire jack located right before the extension joined the bar and then slid a 6 foot pipe on the bar handle. Gave a long slow tug until the nut made that popping noise and off it came. I've included some visuals for y'all. To get the ones on the two cam pulleys off, I took the valve covers off and used a 24mm wrench to hold the cam and a regular socket wrench on the nut/screw to take them off. On the cam there is a spot about midway, formed to accept the wrench. DJSG3

Where you getting your power from? Sounds like that's where your problem is. In the old days it would be the coil causing the interference your hearing. If your running a power cord from the battery, make sure it's shielded and away from anything electrical related to running the engine like the alternator, plug wires, the coil and distributor. If your getting your power from somewhere else...don't use the battery. The Scosche install kits available most anywhere is your best bet for wiring. DJSG3

Have you figured this out? I'm about a week away from being where you are in this post and if you know anything please post. Thanks, DJSG3

First thing you are going to need is a new gasket for your intake plenum. That would be that aluminum thing that rises up from the top middle of your engine and leans over the back spark plugs. To get the plenum off requires the removal of about 10 bolts,nuts,screws. Luckily you can disconnect it from the throttle body without having to remove said body. Tape and mark any wires/hoses you disconnect. The gasket you will probably have to order online because most parts stores will only sell you the whole set of gaskets for the intake assembly not just the plenum gasket. Spark plugs should be either platinum or iridium-tipped. DJSG3

Greetings, I'm dealing with a 1993 ES300 and in the process of giving it a tune up I noticed that the pcv valve didn't have a rubber grommet to snug into. So I put one in and two trips later the Malfunction light comes on and gives me two codes #21 & #28 both of which deal with Oxy sensor. So I'm wondering if anyone here can tell me what the connection is if any? On a side note, whoever designed that plenum to hang over the back plugs like that should be taken out and shot, what a beast that was :o) DJSG3

Hello, Can anyone tell me what years, if any, the strut springs are interchangable for a '93 ES300? Also what, if any, tests or reasons for replacing them are there, other than being broken? DJSG3
