    Has anyone heard of or had experience with Supreme Auto in High Point North Carolina?

    They're telling me they will change out my head gasket and clean out the EGR system for a total of $1200

    i'm in Asheville and can't find anyone to do it for less than $4000. So I've gone the route of looking into buying a JDM engine and swapping out. High Point is 2.5 hrs away

    My 2011 Prius has 206K miles, new Toyota hybrid battery, new 12 V, new brake booster, new brakes. Ie. There's too much $ this past year to give up. the 1200 all in also sounds too good to be true. Hoping for feedback.
    Thanks.

    It's doable for 1200 generally if I was charging something like that I would make you buy the gasket you're going to need four quarts of oil almost five whatever a bottle of oil filter engine coolant all that's coming out You're not going to save all that so something seems to be a little off when you have this apart doing the head gasket you would be a complete foolish person not to at least change the timing chain and tensioner if not the plastic guides also if they're broken you know that's another $150 worth of parts but you would be really pound foolish not doing that It's bad enough you're not going to send the head out and have the valves ground but that's another whole story so y the labor on all that would be about right. But you need more than just a head gasket or it would be like I say really silly not to at least deal with the timing chain he has it off already doing this work and all of that with your mileage got to be kidding so then that would push the job up into the you know another three $400 probably He's got to have this stuff all apart to do the head gasket so what he puts back new would just be someone having to round it up the timing chain tensioner guides if needed etc possibly a new oil pump at this point I think that's off when the timing covers off those are just basic precautions none of that's real expensive but it all adds up these are things that most people or a lot of people don't think of when they're doing a head gasket job like this and especially with 200k if you have a timing cover mounted oil pump it would make sense to replace it probably a new water pump if that's not already been done or while you have it off check the impeller make sure it's good but a new one if needed just a little things like that because once you have this all back together something like that fails and you're right back to where you are now and you barely driven the car seen it happen at least once already pretty soon you have $9,000 in a car that's not worth $6,500 or what have you

    I know nothing about them but going back 3 years they have nothing but 5 star google reviews. I would take the chance and as TBT says, ask them if they recommend anything else while they are inside the engine. It is your choice to say yes or no to them.

    I second @Tombukt2, stated - Do a timing set replacement since the head is off and they're there anyways and valve guide seals. At 200K, I guarantee that the chain has stretched a bit and the plastic guides are worn, if not cracked, chipped, or on it's last legs - take this opportunity to pre-emptively solve that problem or possible future issue. Labor cost is much more expensive than the replacement parts, so your good for at least another 200K, assuming nothing else fails.
    The main question is would this be worth it? I would ask how much oil is the car burning between oil changes? 5k or 10K oil changes? All this "top end" work isn't going to fix stuck rings or abnormal wear in the combustion chamber. High oil consumption will eventually foul your CAT, but I understand that NC is very lax in EPA laws for your car, so replacing that isn't going to break the bank.

    Just my 2 cents and something to think about before "pulling the trigger".....

    I'm not burning oil at all. The only thing that goes down is coolant

    so it's not burning oil at all, this fixes that you're suggesting, would that be solved by just switching out the engine? Is it all part of the engine or separate?

    Well at this point, I'd ask for an official updated quote. Tell them you'll need the valve stem seals, timing chain, chain tensioner, and chain guide replaced while they have the head off. Additional labor cost should be minimal, but parts cost will go up a bit.

    Good Luck..

    PS, ask for the old parts they replaced back, just to keep everyone honest:) You may not be able to identify the parts, but they don't know that....

    These are all parts of the engine. If your not burning any oil at 200K miles, or even a pint of oil - you've got a GOOD engine. I wouldn't swap it out with an engine with an unknown history - chances are you'll get a worst running engine that burns oil.
    I don't care what a used engine dealer says; his job is to sell you another engine. He can say that grandma only drove it to church every Sunday and it's a low mileage engine - that can't be verified without the donor car's VIN and who knows if that was the motor attached to that VIN. Your gen3 has know head gasket issues, whose to say your not going to be in the same situation a year from now with that used engine? If the updated gasket materials is used, you have a better chance of this problem not reoccurring.

    can you be specific on what you mean by all head gasket materials? Mechanic said he'll replace it with feblor head gasket and will clean the EGR system. What specifically should I ask him to do otherwise? I replaced the water pump a year ago.

    You don't NEED to replace the timing chain, or tensioner or guides.
    Valve guide seals, yes.
    And NOT burning oil is very good. Keep having that oil changed at 5000 miles.....
