Why don't we use lexus parts? I know they cost just a little more but I wouldn't go cheap on brake pads. Keep this in mind, Rx300 have the updated pads so make sure you get the right part. Aftermarket pads will squeal! Btw, there is a tool that you can compress the caliper pistons.

JPI

Nice to know that you are making some good power. My project is on hold for now, the shop is too busy and I couldn't keep up with all the work coming in. I tried to email you so many times, oh well I will catch you later Jon.

JPI

It's cheaper for the ES300.... wait until you go into the I6 and V8............You don't really need the tensioner unless it needs one. I would worry about the water pump than anything else.

JPI

You will need to look at the low and high side reading. A/C repair is never a DIY, bring it to someone certified and let them fix it. Good luck.

JPI

What buttons? There is a nitrous and turbo button located under the kick panel, becarefully otherwise your Ls400 will turn into a monster. B)

JPI

its 90K on the mileage............

Only $1500 for the entire 90K service at our local KC lexus shop ;)

The price is cheaper at JPI. ;)

JPI

this is one of your oxygen sensors going bad i would recommend taking it out and cleaning it, also there is a specific test that will show if the sensor operates properly, but first take it out and clean it.

How do you clean the sensor?

29psi ..............AEM will control everything......

Here are some pics of the na-t set up vvt-i

TT rod is on the left and GE VVt-i rod is on the right

TT piston is on the left, as you can see it has a deeper valve cut and deeper dish. GE vvt-i piston is on the right, not much going on there.

Jon,

Got any pics?

The po440 is a small leak from Charcoal Canister to fuel filler neck. To properly diagnost this problem, you will need to apply vaccum on the section mention. Then the valve and watch for pressure drop, Also check the gas cap to see if it holds pressure. Having a lexus scanner will also help, it will tell you what condition the vehicle was in when CEL coming on.

JPI

Using the Lexus Scan tool never work for us. We open the nipple up and pump the brake 10 times, need to this to four corners.

JPI

looking at 500whp ;)

Why are you replacing the Headgaskets? Is it blown? Are you losing coolant?

JPI

I guess these people don't care about their work. This is what we do to prevent these things happen at our shop.

1) After every oil change. We start the start up for 1 second and check the stick

2) Put some rags under the oil filter so They will catch all the oil

3) Fender covers are very important. We don't want to scratch the fender

JPI

Check to see if the Timing belt and water pump has been replaced. Lower ball joints tend to fail at this mileage. Strut rods broken. Engine mount tear and wear. Other than that check minor things. Like seatheater(it isn't that great on the Gs anyway). Have any question. Shoot me an email jpimportz@yahoo.com

You can find the full story here: http://www.badbusinessbureau.com/reports/ripoff82160.htm As you'll see me battling it out with the customer service director.

Basically I took it there to have a simple brake pad replacement. I had no problems with them in the past....of course at a different location. The technicians were the problem.

I took the car to Lexus the same day they damaged the part and they bled it completely with their Scan Tool, which was a computer device, the result was the damaged part.

You can't bleed the brake system with the Lexus scan tool. I'm stunt on this matter. Did the guy ever try to bleed the brake system? There is a proper way to bleed the air out. You can't just suck the brake fluid out. Please keep me updated on this matter. I wish you are close so I can take a look at your car.

JPI

I guess I'm a drug dealer since I'm going to have a turbocharger on my GS300. Actually I do have taste.......

jpi

The tensioner hardly fail so the dealership is right. When replacing the timing belt and water pump, you want to inspect the bearing to see if they are still ok. But it's your call. I'm just speaking from my own experience with lexus.

JPI

There could be a lot of things cause this problem. But my suspect is the expansion valve. The only way to know for sure is hooking up the a/c gauge, we need to know the low and high side reading. We can't guess on a/c work. I'm sure there is an Independent lexus repair shop in your area. Everytime the a/c doesn;t work, it doesn't have to be the a/c compressor.

JPI

I would flush the brake system and check to see if there is any air. Your lexus dealership trying to point fingers. BTW, why would you bring your lexus to a muffler shop? Did they try to fix it?

JPI

My wife just blew the head gasket on our 97 450. It has 156K on it. I'm wondering how common this is, and what are the chances of a more serious underlying problem. For the most part, the truck has been very reliable and maintained well. Based upon a number of things, I'm not sure if I should "open the can of worms" or cut my loses and move on. Not sure if it has red or green antifreeze at this point.

Any history that could help me in my thought process? What's the odds of this being "just a head gasket"

Thanks,

David the Driver.

How do we know it's a blow h/g? Oil in coolant? Engine consume coolant? I've seen a couple of Lx450 h/g failed. But the V6 is notorious for blown h/g.

JPI

Here are some pictures of the na-t project so far. I will fill you guys with the details later on.
