    As of this post I am so aggravated and angry I am am thinking of just trading the truck in on something other than a Toyota (not likely)... For those who don't know I have been getting a puff of blue smoke from a cold start along with and INCESSANT taping from the right side of the motor plus a constant 6-7 MPG...

    First trip to my trusted mechanic was fruitless, he changed the oil and told me if I continue to get 7 MPG to sell the truck....
    I bought a ODBII reader that showed only a misfire on cyl 7.

    Next stop was yesterday, I decided just to take it to my local Toyota dealership as I was positive they have all the right equipment to track down a problem with their product. this is the response I got.

    "Eric its **** , The Tech started the car with me and there was no noise from the engine . WE did notice blue smoke at cold start up but noticed it did not stay blowing blue. The tech states its normal for it to burn some oil and start up. As the oil can stay in head from the lifter."

    they also informed me on the phone that my bad gas mileage is from the cold weather....add to this the fact that NO ONE can seem to hear the constant tapping that is REALLY loud when you first start the truck...

    At this point I called corporate and got them involved which succeed in the dealership calling me and regurgitating their original message...

    I will be trying one more mechanic i know and if they can't figure it out then it will be time to sell as i am spending almost $300 month on gas.

    How about a compression test? Is the truck using excessive oil? Sometimes simple things cause huge problems. And I’ve noticed with Toyota they are hard to track down because one thing wrong causes multiple codes to pop up. Do you have a laser thermometer? Maybe you have a dragging brake caliper. Check your rotors next time you’re back from a small trip. They should all be around the same temperature front left and front right, then left rear and right rear. I’m curious about the PCV valve as well. Cylinder seven misfire. Try swapping the coils around to see if that misfire moves. There are just too many variables. I’ve even heard of dead lifters in different brands.

    I know these trucks get bad gas mileage but that’s pretty bad. I only have a 2 inch lift in the front on stock tires. I was only able to get 16 1/2 miles per gallon at 70 - 75 mph on the way back from Las Vegas. I mean I was seriously trying to see how good it would get. My tires are pumped up and I did not even floor it once. I think this was the most mellow I’ve driven for four hours straight in my life LOL.

    Blue smoke means a couple possibilities:

    Worn piston rings (seal)

    Worn Valve guides, and you will usually hear a tapping or rattling.

    That truck would be gone if it were mine.

    You know what? You’re right that bitch would be gone! Take it to another dealer and trade it in. I wouldn’t give up on Toyota just yet. There’s no telling how it was treated before he got it if he bought it used. Maybe it’s just a lemon.
    If it’s not something simple and the dealer is not very helpful, see ya! This is why I decided to throw in the towel on my Chevy. The LS2 motors are known to throw bearings.
    I cut open the oil filter and found brass shavings. I wasn’t into a motor swap. Goodbye!

    If he has been getting #7 cylinder misfires, there might be a good chance that the cylinder wall was washed out (raw fuel), and could be low on compression. A leak down test will verify what he needs to know. Not sure he wants to invest that kind of money in a failing motor.

    that's what my add will look like.....

    I just responded to Toyota corporate and informed them I am not looking for a freebee but I want them to direct me to someone who can PROPERLY diagnosis THEIR product.
