I'm wondering if anyone would be willing to talk on the phone about some issues with my 37? It's so much easier to quickly talk through things on the phone. I'm also located in Austin, so if any central Texas flathead owners would like to talk or swing by I'd appreciate it. Just send me a PM or email at: tevickery@gmail.com.

The usual reason for the appearance of blue smoke in the exhaust is overfilling the oil pan. I know the books say 5 quarts, but without an oil filter, the correct fill is 4 quarts. Most 85 HP engines don't have a filter. If you didn't change the oil pump, or the sender, the pressure is likely just a coincidence. Most old Ford owners worry about low oil pressure. I'd just drive it after checking the oil level in the pan. It is very likely the problem will go away.

supereal, thanks again. this is not the smoking issue - that cleared up. my father laughed at me when I asked about high oil pressure - he said they were always trying to get pressure up on old flatheads. I have other questions, but the one I'm wondering most about is if the rebuilt skip haney pumps aren't getting oil, would that make the pressure higher post-install? the haney instructions call for making sure air passes through the water pump oil passage before installing his pump by blowing into the fuel pump oil insert (as I recall). I don't think we did that when we installed the pumps. easier said than written.

Tev, First of all are you sure that your oil pressure is high? Have you measured it with a mechanical gauge? If the passages from the oil gallery to the water pumps are plugged, it should not raise the oil pressure. The oil pressure relief valve should control the pressure. The only way that you can be certain that the water pump bushings are getting enough oil is to remove the pumps and check for oil in the passage. I have found that after a while, pumps rebuilt by Skip will spatter the frame and engine compartment with oil. If you are a member of the V-8 Club, look in your Roster for a member near you. They may be able to discuss your issues or direct you to someone that can. If you are not a member, you can join for as little as $15 with the Roster and NO V-8 Times.

The "new" water pumps sold by major vendors don't require oiling via a passage from the timing gear cover. They have sealed bearings. As said above, don't worry about oil presure until you have checked it with a mechanical gauge. That will tell you if the problem is a failing sender, wiring, or the gauge, itself.
