Low oil pressure
My father has a 360 and he say's it wont hold oilpressure. It starts up and as soon aqs it warms up it loses oil pressure. He said its fine just hauling brush around the property for a couple houndred yards. I dont kow what to tell him accept the oil pump might need replacing. Is there anything i can tell him to do that might help. He's getting old and he cant pull the engine out and rebuild it and he aint got the money right now, but I can probobly send him an oil pump and he shouldnt have any trouble with that. He's runnen strait 30 wt too. Any ideas?......Ego

well by the sounds of it egoman it could be one of two things, one, a plugged up screen on the oil pump, two the engine is in need of a rebuild. i would suspect the engine needs rebuilding cause if your running 30 weight oil now and the pressure drops that telling me that you have a lot of wear in the motor. does the oil pressure drop right off to 0 or is it just low ?

I would assume its not registering very good like 0 the thing is he cant rebuild it, What wear besides and old oil pump and maybe clogged oil passages could cause it? I might have him try some Rislone or something to help clean the passages some and check the pump.

Well Depending on how many miles it has on it? how often the oil has been changed?How many years its just been driven on the farm? and plus like kurt said...trusting a 30 year old gauge is Questionable? Dont trust and original gauge unless you can verify it with a mechanical gauge.. and it just could be a sending unit?

Could I get him a new rocker assembly? Do you think that with a new pump might help? I know its always like that on the FE's its just that now after all these years he's tellin me "it just won't hold oil pressure", so its gotta be really low now.

EgoMan; many years ago on my 69 F250 with 360 engine with 470,000 miles I had the oil pressure bypass plunger stick in the open position. The engine had the original aluminum or die cast oil pump. After a cold start and warmup the pressure kept lowering until on the freeway I had 6 pounds and lifters collapse. The plunger bore was worn with a ridge that the plunger hung up on. I gave the motor a valve job and rolled in new main and rod bearings at 210,000 but left the old pwmp, wow at the time I saved money. Unless you have a sludge bucket and really worn and dry rockers it's hard to kill a FE. I broke 5 chebby V-8's before I woke up to FE's. Good luck, Carl.
