Hey there f150 fourmr'z I got some questions and am in need of advice.

Too start....
1992 ford f150 302 4x4, 114,000.

I have done quite abit of work into my truck since I first got it, https://www.f150forum.com/showthread...502#post127502.

Now so I did all that work that you see if you went to the thread above. Everything was fine before I did all the work and I only had a water pump squeal from the water pump being old. Now I replaced that along with others and it's now that I have my problem's. My crankshaft has alot of play to it, I'd say at least a 8th inch if even a little more.

For the problems/symptoms:

Acceleration is defiantly alot slower, but there is a slight knock/ping when I accelerate. Oil pressure, let's just say I couldn't use the gauge if I tried. It's below low when not moving and truck running and then it goes up too half when i have my foot on the gas, but once I let off she drops. I thought it might of been the EGR was sticking because I had no problems before I did all this work and thrust bearings didn't seem logical but now that I see how much play I have I don't know were to go.

Brought it to the auto mech. and they said it's the trust bearings and they said 302's aren't worth the rebuild this that and that, kinda just made me shrug my shoulders and bummed. Anyways, they say just dump the truck but I have put alot of money but more so work into it and would hate to just ditch it. I guess my main question is, should I do a rebuild? should i junk it? swap engines? quit life? no, but I don't know what to do as far as write it off as a loss. Run it tells she blows or try and prevent a problem or see if it's something as small as the egr unit. I am in high school, taking auto 2 here next semester so I don't know if I should pull the thing and do a rebuild or if I am getting myself into a expensive job that won't solve my problems.


Any advice or what you think I should check for problems let me know I would thank you so much!

Thanks again guys!

I'd run the motor and at the same time start building a 351W to drop in it afterwards. mounts are the same, as are alot of the parts you've already swaped. the rad is the same, same tranny and flywheel ect ect. get an intake off ebay and roll with it.
the 5.0 can make ton of power too, so it just depends on YOU.

get another 302 and start the build and drive yours

or

get a 351W and upgrade.

Thanks for the reply that makes sense, I been looking for a used 302 I can rebuilt tell mine takes it's last start on me. Do you know what symptoms I would be getting if my EGR was getting stuck open or sticking?

The EGR won't cause low oil pressure, if that's what you're thinking. The oil sending unit is probably bad, the factory gauges don't work so well. Try reading the pressure with a mechanical gauge. My oil gauge drops to zero regularly and it's still running. The pinging and lack of power is probably the timing.

FOMOCO466

the factory gauges work off of @ 5 psi. a good rule of thumb is 2-5 psi needed for every 1,000 rpm. hook up the mechanical and go from there.

if you really wanna go cheap, even though i'm all for a rebuild, jack the engine up, drop the pan. take the #3 main cap off, put a new thrust bearing in it (theres only 1, two halves). replace the oil pump and keep truckin.

I agree with Dixie. It wouldn't hurt to replace the oilpick up tube while your down there. And nater I'm in high school too and taking construction 4. Do you gave skillsusa in your area?

Nater123

Sean- Yeah I figured that, I just like didn't understand the oil pressure gauge. I think I might try a rebuild, now should I just ignore the Oil Pressure gauge? I replaced the oil filter with a Master Craft and then a new Oil pressure sensor.

Dixie- So what one's would I replace? Like can I get a link to were I would purchase them or is there a rebuilt kit? The auto mech. said that if I replace the main thrust bearings it isn't saying it will fix all my problems. He said that I could replace them and put it all back together and then have the same problems or there might be damage to my block or crankshaft itself from it moving around or having that much play.


James- Yeah man great to hear, another High Schooler bro. Ya I took Building Construction 1-2-3, in 2 we made sheds. Then in 3 it was like a garage and mapping out in c.a.d and stuff. I don't know about usa thing man but we have advance placement stuff for like college or tech stuff. Were you located?

Okay, now if I was going to jack the engine up and did all this what would I want to do when im down there and where should I buy my parts, or just a local parts store?

Thanks again guys!

I replaced my oil pressure sensor too, and it worked for a little while. Then the pressure dropped again. You can try to ignore it, I try my hardest to ignore mine. It does make you worry a bit but I've gotten used to it. You should probably go ahead and install the mechanical gauge so you can get an accurate reading, and it may make you feel better seeing the right pressure. I've been meaning to do that to mine but I've got too much crap to spend money on. I'm pretty sure it's just a bad gauge reading or my truck would have started knocking and tapping a long time ago.

Nater123

Yeah that make perfect sense. I agree with you there for the most part in what your saying, my gauge got worse but it's the same old ford gauge I think . I want to like super glue mine to normal just so im always looking down like . Anyways is there anyway of seeing if y EGR is sticking at all? What are your thoughts on cleaning injectors or replacing etc, do anything or not something that crucial?
