1993 rx-7 pob
I just bought a 1993 mazda rx-7, everything is stock except for the mufler, i recently started to notice a power decrease over time for the last month, the boost meter was not puting out the normal amount of boost, and i started to hear the blow off valve, before i never heard it, then when i got off work today i opened the hood looked at it and noticed that when i reved up the motor there was a small amount of smoke that came from where the turbos are. anyone have any tips for me, this is my first rx-7 and i tried to find a service/repair manual for it but i found nothing. If anyone has any tips over it or might have a good idea what the prob is feal free to leave a comment. thanks

Check all the piping and look to see if there is a oil leek by the turbos too. The power decrease could be from a boost leak. how does your boost gage act when you are driving?

yea but when i first got it i never heard it, the blow off valves are stock, when i first got it and gave it some gas on the streets it would never get that blow off sound but now since my boost has droped slightly week after week its geting louder and louder, the boost gage will got up to the .2 bar range then just stay there then your driveing, i can feal the first turbo then at 3k rpms i feal the other one kick in. i dont know what that hell the prob is

I notice when i took the filter out it was a k&n filter and it had some oil like substance on it, i looked to where it was leading to the turbos and there was a slight amount on the walls of the inside pipeing.
