    I make and have in stock three styles of Adjust-A-Covers for adjusting SBC flat tappet hydraulic lifters with the engine running. They are NEW and come with eight plugs and directions. They cost $60 plus shipping. I have used these myself and have sold around a hundred of them. Everyone that has bought one of my Adjust-A-Covers loves them because there is little if any mess when adjusting the lifters with the engine running.

    To send a PM , a private message, just click on the avator and you will see the option to, start a conversation , and those covers look like a great solution to adjusting the valves without getting oil everywhere

    Estevan and I "communicated". He bought a centerbolt and a tall Adjust-A-Cover.

    Understand that I have been "doing" this (working on vehicles) for 60+ years and have been quite successful at building small block and a couple of big block Chevy motors (along with every other part of a GM product!).

    I learned how to adjust SBC and BBC hydraulic lifters from what I still call master mechanics (one of which had a 65 Chevy II Nova with a 327 SBC in it back in 1969). Yes, you can pre-adjust them with the "IEEIIEEII rotate the engine and adjust the rest of the " EEIIEEI" (whatever that sequence is!) and get them close. AND if you know how to degree a cam (which I learned how to do when I was a mechanic on a dirt track car in the early 1970's) so that you know EXACTLY where TDC (top dead center) is so that the harmonic balancer is ZEROED in relation to TDC of the #1 piston AND you put a mark at each 90 degrees on the harmonic balancer (90, 180, 270 degrees) OR put a timing tape on the harmonic balancer that shows all of that, you can adjust the lifters with the engine off.

    BUT to ACCURATELY adjust SBC or BBC hydraulic lifters you should adjust them with the engine running. AND it makes an unholy mess even if you use those "clip on the rocker arms" POS (been there, done that, HATED IT) which is why I made the first Adjust-A-Cover 50 (yes, fifty) years ago when I put a new cam into my 63 Chevy Biscayne!

    Adjusting valves with the engine off and intake off is just as accurate because you can physically "see" how much preload each lifter has. People do the oil bath method when they don't want to go through the hassle of removing the intake. Cardinals valve covers will reduce the oil bath by 95% I would guess.

    Actually, my Adjust-A-Cover almost eliminates the oil mess. Some of the knockout plugs may weep a little if any oil which is easily controlled a rag.
