do any of u guys no a place that sells 2.8 engines cause i cant find one and need to start pricing them cause i want to bring my truck back to show room quality and when i do get one im gonna be looking at selling mine which has 97xxx miles

junk yard will be the only place. its will be easier to clean up and rebuild yours.

 

[509lifted]

is it hard to rebuild cause i have never rebuilt a motor and this is my daily driver how long would it take to rebuild

 

[stegomon]

it takes a wile...if you are good you can do it in a day....but if you are real good...took me a few weeks to rebuild my 3.0....but i didnt do rings....just main bearings. if you take your time and read the book and fallow it to the letter...and talk with people... you will be fine

 

[509lifted]

thanks and i have another question.. untill i start rebuilding it my motor smokes and i was wondering what causes it

 

[mylittleblackbird]

what kind of smoke? black, blue, white?

Black - Rich mixture/incomplete burn/bad spark
Blue - Oil. Rings/valve seals.
White - Coolant. Water getting into the cylinder somehow.

That is just generalized. Some engines have their quirks and do things a little outside the norm. Someone with more experience with the 2.8 will surely chime in and correct me.

When you provide more specifics as to the color, things can be narrowed down more.

As stegomon states. Rebuilds can be anywhere from a day to infinity. Attention to detail, following instructions, using your head, and listening to what people tell you are all key factors. As it is your daily driver and you've never done it before, I wouldn't plan to do it over the weekend without some very experienced help, and even then you'd be pushing it.

It's seemingly always my experience that a job costs twice as much as I plan, plus at least one tank of gas going to the parts store. Then again, I am sometimes disorganized.

white and blue smoke so looks like i will have to change the rings. and yea im not planning on doin it over the weekend i will most likely do it next summer when i paint it. also i wont be using gas to go to the parts store as i am lucky enough to live a block away from the one here.

s and s engines in spokane wa sales remans for around $1200

 

[509lifted]

wow 1200 i might have to do that when i get the money and sell the motor i have now fom what has been said i think it only needs new rings and it only has 97xxx. where is s&s engines cause i would like to send my cousin over and take a look at a engine cause if i buy it i might be able to trade him for his 4.0 with 2000 miles

 

[509lifted]

oh and how hard is it to change rings on a 2.8 im new to alot of this i just got my first b2 three months ago and i love it it has made it everywhere i needed it to including hauling my deer on the hood. that was out of a washed out logging road

 

[mylittleblackbird]

It would be just shy of a full tear down to get to the rings. Then measuring the bore, buying the appropriate rings(and pistons if the bore is too far over for standard).


Has the engine been left sitting for a long period of time?

Prior to assuming it is the rings, something I've learned about these 2.8's from reading here is that they have valve seal issues.

See http://www.therangerstation.com/tech_library/2-8_valve-seal.html for replacement instructions.

 

[509lifted]

from what i heard from the previous owner only let it sit for a couple months while trying to sell it

The smoke is the valve seals, 2.8s have rubber seals that breakdown overtime letting oil drip into the pistons

That post is gramato-physically impossible.

The oil is either dripping ONTO the piston or "into" the CYLINDER.

haha excuse me, I go to mississippi public schools

If all it is doing is smoking just change the valve seals you can do that without pulling the heads. Use air pressure to hold the valves in put each piston on TDC on the compression stroke and put around 20lbs pressure so it dont push the piston down. I bought a palm spring compressor on it done in about 2 hours. Adjust the valve lash and dont tighten the valve covers all the way down just snug them then do a complete warm up cycle and after the engine cools all the way down you can final the valve lash and button it up. If there is no reason to rebuild the engine poor compression or low oil pressure just pull the intake manifold and reseal the upper end where it always leaks oil between the heads and block in the valleys the oring on the dizzy and valve guide seals. Put new valve cover gaskets and that engine should have 200,000 left on it. You can do a complete rebuild but if the emissions are messed up it would be all for not.
