just got back from a buds house ( hes a mechanic for GM).

had him adjust the valves on my broncII, man, ill tell ya what, what a difference!

thing is as quiet as a church mouse now. he got done, i started it and had to double check to make sure it was running. what a difference. and as far as the rumors about the valve train on the 85 2.8 being noiser than usual?...not true. he got done with m ine, and it it QUIET!

 

Great news!!

 

OOPS!

after the truck warmed up a bit, i found it was running rough. tried to die at stop signes. found out he adjusted them wrong. he readjusted them and its good now! no noise and purrrrrrrrrrz like a kitty

 

Since when would you adjust hydraulic lifters?. You adjusted them on a 2.8. Can the same be done on a 2.9? Usually a noisey lifter means that the spring inside the lifter is lossing it's tension. Lifter replacement is the only thing that could be done to stop the noise. I got one that goes nuts until oil pressure reaches 30 psi.

 

NOT ALL ENGINES MADE BY FORD OR ANYOTHER COMPANY USE STRICTLY HYDROLIC LIFTERS.

MY TRUCK IS NOT HYDROLIC, MY TRUCK HAS ADJUSTABLE LIFTERS. I WOULD SUGEST THAT YOU GET A BOOK THAT YOU CAN LOOK AT TO SEE WHATS WHAT. I WOULD THINK AS A SENIOR USER YOU WOULD KNOW THAT THERES DIFFERENT CONFIGS.

IF YOU HAVE ACCESS TO A NEWER CHILTON MANUAL, RANGER/BRONCO ii 1983 THRU 1990, ON PAGE 1-28 ( CHAPTER 1, PAGE 28)YOU'LL FIND THE PROCEDURE TO ADJUST THE VALVES ON THE 2.8 LITRE V6 ENGINE. ALSO, IF YOU LOOK AT THE PICTURES IN THE BOOK ON 1-28, FIGURES 86 AND 87, YOU'LL SEE THAT THE 2.8 IS ADJUSTED FOR CLEARANCE WITH THE LOCNUT AND A FEELER GAUGE. THE INTAKE GAP IS 0.35mm AND THE EXAUST IS ADJUSTED AT 0.43mm.

ON PAGE 1-29 ( CHAPTER 1, PAGE 29) IT CLEARLY STATES THAT, AND I QUOTE DIRECTLY FROM THE BOOK,
"NO PERIODIC VALVE LASH ADJUSTMENTS ARE NECESSARY ON THIS ENGINE ( 2.9 ) THE ENGINE UTILIZES A HYDROLIC VALVETRAIN TO AUTOMATICALLY POWER VALVE LASH. HOWEVER, SOME EARLIER MODELS HAVE AN ADJUSTING SKREW ON THE ROCKER ARM, WHICH IS WHEN ASSEMBLING THE ENGINE TO PROPERLY PRELOAD THE LIFTER.IF THE ENGINE HAS BEEN DISASSEMBLED,AND THE VALVETRAIN PARTS WERE NOT KEPT IN ORDER,OR THERE IS AN AUDIBLE SOUND FROM THE ROCKER ARMS WHEN THE ENGINE IS RUNNING,PREFORM THE ADJUSTMENT PROCEDURE BELOW"
END QUOTE

SO FACT IS THAT IF I WERE YOU, BEFORE MESSING WITH YOUR ENGINE IF YOUR NOT KNOWLEGABLE ENOUGH TO UNDERSTAND THAT THE 2.8 HAS ADJUSTABLE LIFTERS, I WOULD INVEST IN A CHILTONS MANUAL SO AT LEAST YOU KNOW THE DIFFERENCE BETWEEN YOUR MOTOR AND ONE SOMEONE ELSE IS WORKING ON.DONT ATTEMPT TO WORK ON SOMETHING YOU KNOW NOTHING ABOUT. THATS WHY I WENT OUT AND INVESTED IN A BOOK MYSELF AND SPEND TIME READING IT. MAYBE YOU SHOULD DO THE SAME.

 

Well, I guess you told me. Solid lifters were a product of performance engines. That's why I assumed that the 2.8 would have hydraulic lifters.

 

NP...........

ill tell ya whay, i prefer the 2.8 over the 2.9. i kno0w a guy who has had 3 of them ( 2.9's) and has had nothing but headaches with the things overheating, heads cracking and warping, and just about everything else. if i had a 2.9 in mine, i would run as fast as i could out to buy the 2.8.

 

If I had my way I wouldn't own any V6. V8 is the only way to go. I may be craming one in my BII shortley.

 

yes, the V8 is a sweet way to go, but i look at the gas mileage tradeoff. i would rather save some bux in the gas department as much driving as i do.

 

FYI, Once upon a time when I was driving 65 Mustangs with the 289 V8 I typically got between 18 to 20 MPH's. That's not far from what I get with the V6 so in todays dollars, there won't be much difference in the wallet.

 

THATS PRETTY GOOD MILEGE, BUT IVE FOUND SINCE I GOT MY BRONCO ( IM THE SECOND OWNER WITH 91,000 ON IT) I GET ABOUY 28 HIGHWAY AND AROUND 22 CITY.

 

I get 22 MPG too. Auto tranny here. I could do better if they hadn't stuck a bunch of red lights on the main road.

 

yes, those do hamper progress. my rig is the 5 speed overdrive.
