Did a compression test on the car today it did 70 on the front and 75 on the rear how deadly is that?

 

did you take out the schrader valve on the compression guage and did you have a charger or jumper on the battery when you did the test? those numbers are a little low and would indicate it is time to rebuild. make sure you are getting this most out of your starter when doing the test by adding voltage or making sure it is fully charged.

 

the test was done by a mazda tech and the car has a new battery , alternator and starter. And he told me the same thing that its time for a rebuild. He said that the apex seals are probably worn.

 

first problem is you took it to a mazda dealer....


no offense to them but most dealers (i work at one) do not have knowledge or retain knowledge on older vehicles such as ours so usually their outcomes are usually not accurate.

what was the reason you took it in to them in first place?

 

Huh... you took it to the mazda dealership at got readings like that? Were they not using a rotary specific compression tester? Weird if not, Mazda always does, or are supposed to, their compression tests for rotaries with their Mazda rotary specific compression tester.

 

No i would never take it to a dealer. My buddy is a old school rotory guy from Puerto rico. and is a certified mazda tech. he has his own shop in Miami. And plenty of fast rotories to proove his skills. and the funny thing is that i went there to get a BOV upgrade and ended up findidng out that i need a rebuild

 

does the car start and run fine? if so, screw what he sais and drive it!

 

ya ^, I guess just drive it conservatively and start saving up for your upcoming rebuild... Don't worry about it too much. Do you have a hard time starting it up when it's warm? How many miles on the rex?

Your car looks great.

 

Add some premix to your fuel, that'll help with starting it up at least.

 

He noticed that the car kept flooding when he tried to start it thats why he asked me to do a compression test. When the numbers came up the way they did he suggested a rebuild because my plans for the car are to put a BNR stage 4 and some other stuff. But the car runs fine.

 

luckily the car is only a weekend car type thing so i dont have to drive it avery day. Hes also worried that i might crack a housing in the process

oops... i mean....how do you crack a housing>> ???

 

He just doesnt want me to do any further damage to the car. its a weekend car but when i take it out on the weekends i really get on the car

 

Anytime you can rebuild an engine before it lets go on its own, you;ll make it easier for the builder and save yourself some money in the process. I strongly suggest doing so very soon. The saying goes that turbo rotaries have a way of turning 90psi into zero quickly...

I'd dump some oil or atf or whatever into the chambers, store it and leave it alone until you can afford to do the job.

Or, if you're feeling especially irresponsible, just go ahead and continue beating on it. anything below 80 is at the threshold of immediate destruction, and definitely constant flooding.

 

yeah i understand. Like i said luckily its a weekend car so i wont be driving it for a while.
