quart of ****** fluid in the crankcase. drive it hard for 10-15 minutes. If it stops clattering, then drain and refill with correct oil
Run some marvel mystery oil through your carb, put some in the gas & a qt in the engine. Use it in your gas @ every fillup.
If the previous suggestions have not cured your sticky lifter. Try this: Warm engine to operating temp. Remove valve cover. With engine running, use a soft faced hammer to give a couple of sharp raps on the pushrod side of the rocker arm. Wait a few minutes, you have a pretty good chance this may fix the problem. If still sticky, try again. If it still does not free up, loosen the rocker arm, move it aside so you expose the tip of the pushrod. Spray carb cleaner down the pushrod and rap on the pushrod several times. Repeat several times. Replace and adjust lifer and hope for the best. Good luck.
i had a lifter sticking on the firedome as i was leaving the iron invasion. stopped at the parts store, poured a pint of marvel mystery oil in and in the 4-5 minutes it took to get back to the hotel, the hemi was quiet again.
I also had geat luck with rislone back in 60s have not seen it for years up here also very good luck with trans.fluid also.hopefully not cam losing a lobe
Maybe a dumb question.......how do you actually know the lifter is sticky ? Smallblock Chev hardly ever suffer from sticky lifters. Do you actually have a noise ? What you may actually have is a cam lobe that has worn away and both the lifter and cam lobe are badly worn causing noise......somewhat common on original equipment cams. Or......somewhat common on Chev....if rocker studs are press in......the stud may have pulled up allowing for lifter noise due to loose clearance. Also.....rocker side can cut into stud and rocker will work off to side of valve and cause noise.
With the lifters rockers adjusted. Well the engine is running I can see one of the rockers isn't moving much when I turn off the engine the lifter gets stuck and a second later pops up runs fine till it gets stuck again obviously valve covers off also started looping today
From that description, sounds more like a valve sticking, if it pops up after the engine is shut off. Is the part that pops up after the engine is shut off on the intake side of the head or the exhaust manifold side?
Yeah......kinda makes sense. Engine heats up and exhaust valve sticks. When engine shuts off, combustion temp goes down and valve pops loose. Obviously lifter collapses to allow for rocker not moving because valve is stuck. Not common at all on small block Chev unless head/valve work was done, but rather common problem on 454 big blocks especially in truck applications. Valve stem will gall and transfer metal from guide to valve stem due to high heat.
Check for a broken valve spring at that cylinder, dual valve spring? Bent valve stem maybe, could be as simple as a notch worn in the rocker stud as mentioned earlier.
