[DeTomaso] Oil pressure drop

[Christopher Kimball]

I installed a new sending unit on my '72 and it made the dash guage operate perfectly.  Then, just to be extra-conservative, I installed an additional manual guage and mounted it on the rear engine cover where I could see it.  It reads anywhere from almost 0 at idle to 65, while the dash guage reads between 20 and 60.  I like the dash guage better because 0 oil pressure makes me worry...

I checked the oil pressure directly at the block and the pressure was 65 idle and 70 WOT and never dropped.

Oil pressure drops while driving at higher rpm ... I wind the Cleveland up in rpm as it gets to 4500 the oil pressure gauge drops low ..like to 10. No noises or rattle. It has been running around 45- 70. I am using multi weight Rotilla with a quart of Moray's oil conditioner, kinda like high tach. I checked the oil and it is even with the low mark. I added a quart and have not been back out. NO way I'm pumping 5 1/2 quarts up and lowering the pan level? Could it be too thick? > > _______________________________________________> > > > Detomaso Forum Managed by POCA> > > > Archive Search Engine Now Available at http://www.realbig.com/detomaso/> > > > DeTomaso mailing list> > DeTomaso at list.realbig.com> > http://list.realbig.com/mailman/listinfo/detomaso> > _________________________________________________________________> It’s a talkathon – but it’s not just talk.> http://www.imtalkathon.com/?source=EML_WLH_Talkathon_JustTalk> _______________________________________________> > Detomaso Forum Managed by POCA> > Archive Search Engine Now Available at http://www.realbig.com/detomaso/> > DeTomaso mailing list> DeTomaso at list.realbig.com> http://list.realbig.com/mailman/listinfo/detomaso
