    Morning everyone, Haven't posted in the forums in quite some time because you've all helped fix my problems I've had with my car. However, a couple months ago my engine went out, causing us to rebuild the engine. I posted pretty much the full story (and the general pain this engine rebuild...

    Ok, My story here has been quite an interesting since I decided to rebuild my engine. I posted awhile back for help, and everyone here has helped me immensely for the 4v swap, so here I am, with the progress on the rebuild of my 302 and how it's driving me insane. My mustang was performing...

    I replaced my oil sending unit on my 302 but when the engine is running the gauge doesn't move. I have grounded the wire and the gauge pegs so I know thats not the problem and since I have driven it plenty of times I know the engine is getting oil. Anything else that could be causing this...

    I have searched high and low and all I get is conflicting data and my Chilton’s manual is worthless (in this and many other things). I’m finding 40-60 psi hot @ 2500 rpm’s, 40-60 psi @ 2000 rpm’s, 40 + @ 2500 rpm’s, etc. While all of these should be sufficient oil pressure for the engine, from a...

    I've recently purchased an 87 5.0 GT and while driving it around I noticed the stock oil pressure gauge fluctuates from the bare minimum line of normal to about the 2nd and 3rd lines. But once warmed up it stays around the bare minimum line of normal just above the red 0 line. I have read that...

    2006 Mustang GT manual. I put on a Bama 87 octane street tune yesterday, and had no problems. Didn't notice much (if any) difference in throttle lag, but I think I can feel a bit more low end torque. No problems. But today a few minutes after starting it up and leaving the park & ride station...

    Hey there enthusiasts! I am new to the forum and a proud owner of a 1988 Fox body LX 302 5.0. I recently purchased this car from a friend who I knew back from high school and he has done a few things. New crate motor (only block and head) only has 40k miles on it. Rest is from previous...

    So after driving around today my oil light decides to come on even though my oild pressure gauge is showing normal readings. I noticed that it flickers when i drive on uneven road and turns off when i go over a speed bump or a pothole, or when im on and incline. So my guess is that the sensor...

    93 fox with a 347 stroker. Today its about 93 degrees out and my mustang started running about 10-15 degrees hotter. It runs almost near 220 degrees but i try to keep it around 210. Oil pressure is getting close to 22 psi with all this heat. Usually maintains at about 30 at idle. Im running 5w30...

    Hi, I have an '89 GT and I've been getting really weird oil pressure readings. From start up the pressure seems fine and sits a little below the halfway mark on the factory gauge, but when I accelerate or beat on it the oil pressure seems to drop off very drastically. The motor is almost all...

    So im having an issue with my oil pressure on a cold start. In the morning when I start my car (engine has been off overnight and is cold) the oil pressure gauge goes to its normal position for about two seconds and then goes to no pressure. I immediately turn off the engine and start it...

    Hello guys need some help here. I changed my oil today to royal purple 20/50 with a napa gold filter. I'm not sure what oil it had before this change. The pressure with the old oil would build up to 80 psi at start up and drop to about 25 psi. It would build up as the rpms got higher. The new...

    Hey guys was sitting in traffic this morning when I noticed my oil pressure gauge fluctuating between the o and m. If I sit on a hill with the engine facing down the gauge will sit right at the m once the engine is revved or under load it shoots right back up to o. Normally the gauge will read...

    Hello all, I registered on these forums to see if anyone here can help me with a problem. I've been looking around the Internet for a number of years trying to find a solution but haven't been able to. When the engine of my 1997 3.8l Mustang is warm and in low idle (~700 RPMs) the oil pressure...

    Hi fellow mustang owners! I am in an urgent situation right now. This past weekend I changed my oil & filter and automatic transmission fluid and filter as well. I have been driving my car and all seemed fine, until this morning on my way to work. The oil pressure gauge was constantly flinging...
