compression Question
whats a good compression for a FD?
the one i looked at got low 6's on both rotors. thanks for any help |
under 6 is rebuild time..
above 7 is alright above 8 is excellent |
How much should a compression test run
The local Muzdah dealer wants $114 for this. Is that in the ballpark? I do not trust them to much due to past expierences with them; what exactly is the procedure for the compression check, what kinda of printout should I get from them to make sure they do it right?
TIA, Brad |
$114 IS PRETTY steep if I compression check is ALL that they are doing...
if it was a full "used car" check + compression that be somewhat resonable. They have a special measurement instument and the pull the plugs to test compression.. Each rotor should have 3 readings for the 3 faces...so you should have 6 numbers total.. The reading on each rotor should also not be more than .4 range (high to low on same rotor)... |
I was thinking that was kinda high. Does anyone know what Mazda (Corporate) will reimburse the dealer for a compression check under warranty? I'm going to try and dicker the price down. And that is only for a compression check, I already own the car I'm just thinking about selling it, and some of the interested parties have asked for a compression check. Normally I would think that this would fall on the person buying the car, but I live in Alaska, so that isn't possible for anyone that has shown any interest in the car.

when I bought me second used Fd ...as the buyer I paid for the compression test...so I think they should too...ofcourse the first guy who pays is the one lucken out...but then again if the compression is good..he buys it and has that peace of mind..
|
yup, the buyer usually pays for these kind of things,....so with this compression, how long would this engine last at 10 psi?
|
what was the compression...6,7,8 +... you never can tell anyways..just takes one mistake to blow it...we all know that..
I'd say if it was low 6...I'd give it a year.. hard to say with the other numbers..you cant be certain |

I'd say if it was low 6...I'd give it a year.. hard to say with the other numbers..you cant be certain the interior and ext is in excellent cond its a 93' with about 60k miles in the odo, it has som mods on like ic, dp, mp, profec, exh... he whats 15600 for it, is it worth it? |
If that's US $$ that's top dollar(for a low compression engine)..... The engine is on it's way out...try to talk him down atleast 2-3K...because it's going to cost you about 4K to do the engine when it's time...which could be in a year or so...
|
ok i'll try to talk it down, yes thats usd.
thanks for the tip. |
