1986 Ford F150 6 cyl Four Wheel Drive Manual 255 K miles
Good evening. Last week I experienced an oil pressure loss. My 4.9L oil pressure used to run 50 PSI at 2300 RPM's and 22 PSI at idle while operating at normal operating temperature. Now, my pressure is fine when cold, its around 56 PSI when cold and after engine warms up, it drops to 34 PSI at 2300 RPM and 12 PSI at idle. Oil level is normal and the only other issue that occured at the same time the oil pressure dropped was the front main seal in the timing cover blew out. I had all gaskets replaced last year due to old age and leaks. The front seal was also changed at the same time. Could this be the problem why my pressure all of a sudden dropped?
have the same problem?
