I never had any bad experience with hughes. Anyone has one of their lifters to compare? Thanks Chris

Hughes engines lifters seem to be different, anyone ever tried them? Thanks Chris

That plug is installed... part of my engine building check list...

I compared summit, sealed power and comp lifters. They´re all the same.

I could live with that noise if I knew it doesn´t do no harm. I´ll just tell anyone I got a solid cam in there... But will it last? Do the bled lifters decrease my cam size? Thanks Chris

I have tried to reduce preload by shimming up the rockers by 0.040" , that didn´t change a thing. I still have to use lashcaps to increase preload to rule that out, too.

No I didn´t measure the lifter bores. Used a lifter with wd40 on it to check for any sticking or clearance, but I guess I´m not able to tell 0.002" that way. Oil pressure is at 75psi when the problem occurs.

gliderider06, that seems to be the problem. Thanks a lot for this information. Any brand recommended for lifters? So far I compared Comp cams, summit and sealed power (federal mogul) and they all look exactly the same.

Took some measurements on the lifters. Lifter face to oiling groove: 1.160" oiling groove width: 0.230" Anyone with a used or new hydraulic lifter at hand, please take a maesurement at your´s and let me know your results. Thanks so much for you coming up with ideas! Chris

My fabricated aluminum covers clear by a mile, and it´s there when the covers are off the head...

Headers are TTI 1 3/4". They fit very well, do not touch anywhere. The old gaskets where spotless. I use red RTV every time. Thanks :-)

I used mineral 15W40 with Hughes´ high pressure lubricant. Switched to mineral 20W50 with Hughes hp lube today. Seemed to me that it took longer until the ticking apeared, and it was a different tone (brighter) but after a couple of minutes it was just the same as before. Cheers (switched myself...

I did indeed pay special attention to the lifter bores with this block. Before finally cleaning the block, I honed all 16 lifter bores with a wheel cylinder hone to clean them up, just a couple of rotations to remove any deposits. Then I checked all 16 lifter bores with a new lifter and light...

You´ve got no idea how curious I am... :-) Do you still run that engine? Did you use the same brand of lifters all 3 times? Thanks, Chris

Thanks for your support! I did check the valve´s installed height with a straigth edge, they were dead even. Yes it´s a flat tappet cam :-) The valve covers were removed for inspection and the engine was run with cardboard splash shields, no interference there... Talked to an engine guy and he...
