my truck has 82,000 miles on it and I think it sounds ok... I read somewhere that the valves should be adjusted every 36K and some people hadn't touched them for 200K will this hurt the engine if they are out of spec? is this a precaution or do they really go out of whack that easy? and finally what will the truck do, or sound like when the need adjusted?!?!

 

Never a bad idea to perform a little PM.

Properly adjusted valves help efficiency and = less fuel used for the same job.

At 82k you ought to do it.

Loose valves will wear the whole valvetrain more than properly set valves. Tight valves get burnt. The good news is that these engines generally go loose, so nothing really bad is going to happen if you don't do it right this instant. But you really oughta do it at some point.

You can hear them clatter most on overrun.

 

i've heard of some people not doing it till 200K!! holy crap!

whats overrun???

 

Coasting down a hill. You'll hear a lot more noises when you aren't on the throttle.

 

lalala-lala

 

same here!


But no noticeable noise on over run.

 

it's so easy you should do it just for fun...

 

just do it youll feel great and your truck will be quieter

 

easy job to pull covers and at least check them. At least you do not have to remove half of engine components to get to them.

 

I'm just freaked out about messing something mechanical up!! I read the sticky and still cant figure out how to make sure cyl#1 is tdc... they're talking about watching valves to see whats moving and..... I dont know.... if I could get a clear description on how to watch the valves move to check clearance.. I dont care if I have to go cylinder by cylinder..... the picture on the sticky doesn't show anything.....


p.s. I cant get much overrun here in florida.... no hills

 

What are the valves suposed to be set to.

 

I recently did mine. Its not that big a deal. I had someone walk me through it being my first time and all. 2 Valves were too tight and one was a bit lose, the rest were fine. It does seem to idle a tad bit smoother but it could be my imagination. I just noticed that my 4WD shifter doesnt shake quite as much =D Regardless, it doesn't wont hurt to do it. It will at least give you peace of mind.

 

Use the timing pin then.

0.010 intake, 0.020 exhaust

 

how long will both valves be closed together? on one cylinder...... Just to get it right I was thinking about going one cylinder at a time and adjusting.... hell, maybe one valve at a time.... maybe i'll do every exhaust valve one at a time watching to see when its closed and adjust....then intake... might be faster then learning this whole timing thing. will this work?!?!?!? longer but it makes sense right??
