Thread: 7.5 professional rebuild 15K miles no oil pressure at hot idle

Tweet

I have heard about 460 oil pumps mounting boss cracking. Maybe that is the issue. Engine has a new Melling pump but it doesn't have a beefed up mounting boss like some do. Thanks for the Ford oil gage info. That is why the gage goes from zero to the same level each time. Sorry but the only way I can describe my feelings about this fake gage is Rat Bastards. There is still an issue just a different way to think about it. Looks like a tear down is in order. I was afraid that maybe I wiped out a second cam but there is no valve noise. If the cam was gone there would be valve noise all the time.

Not necessarily so, I wiped a couple of lobes in a 400 sbc and I don't remember valve train noise, just extremely low on power. BTW, I lived in Lebanon until I was 8 years old and my dad, in the early 40's, was the night manager at the Golden Lamb.

Small world! Lebanon is a nice place today. Jazz and country music festivals in the streets in the summer. Santa comes to town in a Christmas horse drawn carriage parade in December.
Got to get my truck fixed. I can't get my Camaro to the strip with out it.

It was a nice, sleepy little town as I remember it in the late 40's early 50's. Where do you run, Kil Kare?

KilKare and Norwalk. KilKare has been completely re-paved. they completely remove all of the old track and poured about 24" of concrete and then milled it flat. They now call it The House of Bite. Stupid name but true. Best track around now buy same old old old bleacher seats! Splinter is the butt with 40 year old planks to sit on. LOL

Those planks could be closer to 60, Kil Kare was running when I flagged at DAHIO in 59.

My old '90 F150 has always amazed me with the rock solid oil pressure. At 130K miles, it still hits the same spot on the gauge, and now I know why!! I had never known the "idiot light" sendor fact until now..... I think that there may be a way to "fix" it to read a true analog sender output, but not sure of the details....
