Thank you for taking time out of your life to try and improve other's.

Excellent video. Saved me $450.00 on a top end rebuild that was already costing me a lot. I figured it out but I personally could have used more detail on the reassembly. Thanks for taking the time to upload this content. My lifters were frozen.

Bless you man...Blew head gaskets and also found cracked heads after teardown. I'm at $1900 in tools & parts for rering rebearing along with the cost of new Kings heads. Chose to pull engine for a complete clean due to the oil gunk & sludge. Everything needs looked at as lifters look OK but will follow your example to get em clean. BIG THANKS

Thank you for the content. I have harvested two used sets from 1st gen explorers. i'll take the best 18, after initial inspection (want some spares) disassemble, clean, then have them cryo treated and micro-polished. i know its beyond overkill and pricey...but it'll all be done right and spotless. overall, the cost per unit won't be much more than brand new oem lifters.

Yeeeeaaaaaaa just gonna go ahead and order new lifters hahaha fuck that. Great insight on the break down and what all is involved 🤙

Nice. I've done purdy much everything to my engine, except this.

Very helpful vid. You don't see too many like this. I plan on rebuilding my ohv as it's a 2000 and hasn't had anything changed but the gaskets. It still fires up and doesn't burn any fluids, but I want to rebuild it for a supercharger within the next few years. I'm not sure where to start though.

What would cause a lifter to lose its prime over night? 🤔

If you did have to replace with new lifters, dont they say youre supposed to put a new camshaft as well or not neccessarily.

I have a 92 ranger with the 4.0 ohv is the 92 the same shit?

What are the purpose of the black caps.i had two missing when I replaced my head gaskets but my engine was sounds no noises like tapping etc.

good morning friend, i have a ford ranger 4.0 v6 ohc 1995, i'm from brazil, but the van is american, i have a noise problem with hydraulic tappets, can you tell me if i do this cleaning will the hydraulic tappets return to normal operation? or do i need to replace with new ones?

anyone know the shaft diameter on these 4.0's?

Not necessary for a roller cam

if I put flat to piston in mine will the valves hit or will it be ok

All of the valves on my heads are not even close to touching..There's probably .025 or more difference between them

and fyi..thise heads have been to a machine shop,have had a valve job and NEW valves installed. .also new pushrods and rockers were used..this is simply to show how to clean a lifter that gets clogged which this motor is famous for..nothing is wrong with the lifter other than its a dead end when it comes to oil path and gets clogged..lifters run $30+ a PIECE for this motor when nothing normally is wrong other than clogged...reusing parts that are not broken is not the wrong way or a band aid..sorry go waste your money elsewhere

SOUND SO LOW...A SHAME
