[broncomitch]

so, after this video i desided to take the valve covers off to see how dirty the heads where....and look what i found.

Not real sure what your talking about here. Did you forget to add a pic? Or is it just now you have one bronco that runs?

Tried to open it, will give it another whirl in the morning...

 

[broncomitch]

sorry, computers hard drive is going out so its junk.



looked at the motor more. looking in the #1 cylinder i can still see honing marks, and flat top pistons. I'm going to try and track down the PO and find out whats up with this thing.


mmmmm. video makes it sound like its running underwater lol i tryed to make a video when the exhaust was off but was to loud to hear anything,so i put the flow's on it and it's still loud as hell but has a really deep rumble. can even feel it in my body and on he ground!

Nice job! Beefy roller rockers and ARP bolts, eh? Nice bonus if they're still in good shape, which they look to be from here.

whats a good way to test them? there not loose and the valve lash is perfect on all of them. who ever put them on really took there time.

tryed to get a pic of the flat top piston's but no go.

 

[broncnaz]

Not tests needed as long as they are not making noise just leave them as is. Look like the rockers I have on my bronco Crane energizers

Sounds like you've got it all apart now. That right? As for inspections, pretty much what he said. But the main one, if it's not running, is just visual. Look for any marring of the valve tips or the roller tips. Pull one apart and inspect the trunnion and bearings (if any. Some use bushings) and look for anything suspect.
Unless the engine had an oiling problem, or was set up incorrectly, or raced extensively, I doubt that there's anything really wrong with them.
You can always check with a manufacturer (they do look like Crane's) to see if there's a clearance spec to go by on the trunnions and tips.

na its all still together. ill pull a few off and check them out. i might be selling this bronco, so want to know for sure what it has and what shape its in. ill be sending the PO a letter in the morning asking him to call me. how much are they new? i can only find a price for chevy rockers.

 

[DirtDonk]

Hmm, well, if it was running ok before, I wouldn't go to the trouble of a deep inspection just to sell it.
Yes, I'm the type that wants to make sure that the next owner is getting what they're paying for, but unless you know or think there's an issue, it might be more trouble than it's worth. After all, roller rockers are pretty robust unless abuses.
Up to you though. If you want to get in there and check a few out, I'd be curious what you find.

BTW, is this the same engine you're having ignition troubles with? Or is it another one entirely?

Paul

 

[broncomitch]

same. lol

 

[broncnaz]

Hard to say what they cost now but I do know they were cheaper than almost everything else when I bought mine.
