Valve Noise?

[OlsonCustoms]

New to the forum, lots of great info here .... ive got a 95 astro with the 4.3 vin W and its starting to sound like the rockers on the pass side are clattering?? runs ok still and have not tore into her to investigate, any advice or similar issues that yall know of?? thanks for any help , part of me wants the 4.3 to die so i can justify the V8 swap but its just so darn dependable now.

Pull the dog house and sound it out with a long medal rod to your ear.See if you can get a better idea where it is coming from.Overall the roller valve train is not normally a issue.What kind of oil pressure are you seeing??.I didn't see where you posted how many miles are on it.

I would doubt it's your rocker arms, more than likely it's the lifters that have failed. You can put new ones in but then I would sell it asap. Probably time for a rebuild or a V8.

Oh man,now you go high tech on me. Just thought if he had a pc of threaded rod,he could use that.Then use the $5.00 on Mac Donald's value meal.

I'll wait for him to sound it out.

Oh,I owned a new dual quad 427 Galaxy 500 four speed stick when I was a kid in partner ship with a high school friend.

Thanks for the tips, had my wife 3/4 throttle the thing in drive with the brake on and came to the conclusion that its a slight the exaust leak on the pass manifold, guess im just used to listening to big block and stroker fords and chevys too...... man it sounds different in the driver seat and she decided to power brake it afterwards gotta love tire smoke from a Astro especially when a woman is drivin'

My ex-wife drove my hotrod at 3/4 throttle with the brake on, but not in the exciting fun way that yours did, it was more in a smelly not so fun kind of way.
Nice bikes by the way, and welcome to the site.
