diagnosing a loss of oil pressure?
Hello Folks,
Need some help here diagnosing a loss of oil pressure? I have an 86 13B in my first gen and I have swapped the front cover with a GSL-SE front cover. I was at the track and everything was fine. All of a sudden the oil pressure dropped. At idle it was about 10 psi and if I revved it the pressure would rise to about 45 psi.
I figured that I blew out the “O” ring between the front cover and the block. But, I have just pulled the front cover off and it does not appear to have blow out or be miss-shapen at all.
Do you have any suggestions of what happened, how to diagnose it for sure and how to fix it?
Thanks

Put it back together and start it up with a mechanical gauge hooked up where the original gauge sending unit was. For ***** and giggles, you could replace the pump, but I don't think much wear occurs on that type of oil pump.

Jeb,
Are you using the the second gen eccentric shaft?? If yes, have you replaced the thermo-wax, oil bypass, accelerated warmup thing. If/when that fails the oil pressure does exactly what you are descibing.

Hey Ryan,
Good to see you around! This is redwood's old engine and I put in a Atkins soild thermo pellet. I hope school (and life) is going well for you.
I will check the mazdatrix page as well. That is where I got the info about the front seals blowing out. The last time I looked was a year ago, there may be more info for me there.

Say can I get any further input on the " thermo-wax, oil bypass, accelerated warmup thing."?? Also I've seen elsewhere that as low as 30 lbs is considered "normal", is this so??
