What is your question?
2001 Mazda Millenia 2.5l has codes P1250,P1522 and p305.
1. Where is the fuel pressure regulator control valve circuit/selonoid located on Mazda Millenia 2.5l? Thought it was the fuel pressure regulator itself and changed it. But code showed up against and I need to know where the selonoid/valve for fuel pressure regulator is to fix the problem.
2. The car has also code P305, cylinder #5 misfiring.Is this due to the codes p1250 and p1522? Is the misfiring on cylinder #5 due to the failed camshaft timing adjustment valve or PRC valve?
3. On the other hand, despite the replacement of the valve cover gasket, oil is leaking badly around the "neck" of the coil pack (front driver's side)and pouring on alternator (passenger's side). I noticed that type of leaking on most Mazda Millenias in the Junk Yard in my city. Is this problem specific to that type of Mazda?
4. I used stop leak fluid and they indicated that it should fix the leak after 1,000miles. Can that oil leak cause heating problems? Fortunately, the car does not overheat easily as before after replacing the thermostat, sensor, upper hose and overflow tank and cap.
5. Can the failed camshaft timing adjustment valve cause oil leak, overheating or preventing the car from starting sometimes at first crank?
6. Can a tree shade mechanic (usually found around Autozone) fix a camshaft timing adjustment?
As a matter of fact, the car runs good and I drove it for 60 miles without overheating.
Please advise on the leak around the coil pack (is there a gasket around that area that wore off?) and alternator as well as how to fix the failed camshaft timing adjustment valve?
