Help diagnosing engine trouble.

Is it difficult to change? i would ratehr not pay a mechanic to do it if I could myself.

i believe that u need a 5.5mm socket to get thet module out,the modules usually do just crap out but it sounds like it runs fine till it gets to warm so if you got the money change it. besides if it is original its quite old anyways and done its job.
and just because the oil pressure switch works very well doesnt mean there might not be blockage prevent oil from getting through certain pathways.
the dealerships do offer a hot oil engine flush to clean out the engine though

fuel injectors make a noise muck like a valve ticking too
use a long bar and gently put one end to the part u suspect and the other to ur ear then ull find the noise for sure
good luck let us know how it turns out

Would cleaning the injectors help? Would Sea Foam do the trick?

it wouldnt hurt i mean when was the last time any cleaner was put in.
but if u r trying to cure the injector its fifty fifty just think twenty years of plastic exposed tro the combustion chamber they just get worn and noisy over time

I have no idea....The engine I bought to put in it is out of a 1986 I believe...Probably never been cleaned...

In all honesty sweet if your gonna do work on your own vehicle u should go out and get a mini scanner they are like forty dollars avg and will save u many headaches cause even though the check engine light doesnt come on there might still be codes logged into the ecu. and they might lead u to the problem.the codes can be found in the instruction manual or in the tech librairy. it sounds like once the truck reaches a certain temp it starts to act funny is it during short or long drives the 02 sensor doesnt take over engine control till the engine reaches temp, just another thought

an aftermarket code scanner on an EEC-IV vehicle is a total waste of money. you can pull codes and do basic self tests with a paper clip and only a real STAR tester will do datalogging.

yes but as our young friend has said he is still learning so for him starting out a paper clip will be areal pain in his backside.And iwas refering to the aftermarket scanner pulling the soft codes it isnt very often you actually have need to check for the hard codes which of course needs the dealers drb

we could always show up at his house and show how to diagnose properly but its a little to far lol

there arent that many aftermarket scanners that will "talk" to a ford EEC-IV computer....its not like an OBDII scanner.

"hard" and "soft" codes? you mean continuous memory and self test codes? both can be pulled with a paper clip. there are no codes that you cant retrieve with a paper clip. aftermarket scanners are absolutely unnecissary for an EEC-IV vehicle.

It has only happened on long drives...if I drive it around town, it funs great...if I get on the interstate to go to work, that is whenit acts up....

 

[Wicked_Sludge]

could the rattling your hearing possibly be spark knock? that could indicate your timing is jumping forward for some reason (a dizzy or TFI issue).

 

[sweetwaterbroncoII]

The ticking is constant while the problem is going on....it doesn't increase or decrease with acceleration or deceleration......

 

[Wicked_Sludge]

those symptoms sure do sound consistant with a drop in oil pressure, like others have suggested. it might be worth your time to varify the oil pressure with an aftermarket gauge just to be sure.

 

[sweetwaterbroncoII]

Are they hard to install?

 

[Tedybear]

The only hard thing about an aftermarket oil pressure gauge install? Is where they put the sending unit you'll have to remove and replace with the fitting for the oil pressure gauge "Tube". If you have a set of car ramps? It's probably not to bad. The sending unit on the 2.9's is located just about under the power steering pump. The engine probably has a 2" long (or there abouts) extension on the engine port that has the sending unit screwed into it.

What we did with ours? Was to hit Napa for some plumbing hardware, and we made a "T" coming off the port. One end of the "T" goes to a new sending unit (pretty cheap to replace) The other end goes to the adapter/tube for the physical replacement gauge, and the other end screws into the port itself.

Nickles worth of free advice when installing the tube: KEEP IT AWAY FROM THE EXHAUST AND ANY/ALL MOVING PARTS! If the tube melts or tears? Yer gonna have such a mess.....

Thanks for the advice...What would be the problem if it is showing low oil pressure, the oil pump or a bad engine?
