Hey guys, if you missed my introduction thread, my name is Anthony. I'm an electro-mechanical engineering student from Long Island and I have a 1989 bronco II with the 2.9 cologne and 87,000 miles. I've been lurking around the forum for a while now reading up on these engines and this platform in general and all the information has been invaluable, so thank you all so much for that.
Now though, I need some real guidance and need it fast. I've been driving my bronco for about 6 months now. I bought it used from a ford dealership so it's really clean and has been rigorously maintained. It is a rust free example of a bronco II, which is pretty hard to find out here on the island because of the sale. As of a week ago, right when it hit 87,000 miles, I started having some pretty serious oiling issues.
As of now:
- ticking on start up, becomes faint after about 5-10 minutes of warmup
-oil pressure on start up is about 43psi, falls between 15-20 when warm unless I'm on the pedal, in which case it stays around 35
-intermediate LOUD ticking on the highway, which is usually followed by oil pressure of less than 15 psi if I stop the car and leave it in gear. At this point if it's in neutral or park, the psi comes back up. This symptom only seems to happen when I drive on the highway and after it's clicked into o/d. If I drive in gears 1-4 at moderate speeds (up to 50) I have no problem.
-heads really don't have any carbon build up, and after some inspection it would seem they're not cracked. I'm not losing fluid, and there isn't any gunk in the oil.
This needs to be solved immediately and in the cheapest manner possible because I have to leave for the first semester Of my masters in a week and a half, and I need to drive there. 1800 miles to Colorado.
I'm looking into doing a couple of things here and have a few questions. I've worked on a good amount of machines and cars, but I've never done serious engine work.
The oil pump and pickup are a definite, I'd rather be safe then sorry and It can't hurt to get a guaranteed boost in oil pressure. I know this is a daunting task but the works seems pretty straight forward, just time consing. No?
The camshaft bearings. I know this is kind of a disputed topic, but I want to know if it's worth it, given my current symptoms. Is the job complex outside of disassembling the top of the engine? Can the bearings be changed without replacing the cam and lifters? Can this be done with the engine in the car? Is there a write up? (I didn't find one)
Rocker Arm shafts, I know these get clogged up pretty easily, and I'm not sure if it's necessary to replace them all together but does anyone have a method for cleaning them out? If not is the replacement a pain?
Most importantly can this work be done in a 24 hour period by one or two people? is it worth it given the time constraints/ symptoms and condition of the truck?
Thanks for taking the Time, any input is going to be really appreciated.
