Great job. Very helpful

Having valve seat problems any info on removing seat and replacing them?

Thanks! Nice simple video!

Good info, thanks gentlemen

Would i be able to replace my valve seats at home? Or would i need to send them to a shop?

First time refreshing an engine, sat for 6 years not running then a year out in the rain, some water got into the engine but I didn't care too much being I didn't know much, but corroded valves and I was too lazy and unsmart to fix them, now I'm exhausting out of the heads causing way too much heat, looks like it's time to redo everything

How you tested for any leaks after you installed them? Thanks

couldn't find thing spring compressor anywhere here. could order it from a auto parts store for $95 - $110 so I made my own version. except it won't work to get the damn keepers back on. ugh lol

OKAY, can you show how to install new guides on a 4.7 without removing the head? WHY? because my wife's 2000 Jeep is smoking at startup but not while running. I have been told by a local Shop that they can do it for me for a large pile of money.

On the exhaust spring, they have a weird spring guide. Do they go in a specific direction?

hi Jamie thank you for the awesome vid, btw did you have to "valve lap" the valves or did u just install them.. thank you

+futbolero4152 that's a good question and every time you pull valves out of the head take the time to go ahead and grind them in and left them in real good a few extra minutes there will give your car a few extra hundred thousand miles later alright man need any help let me know

Do I install the new lifters prime or un-primed? Also, should I use assembly lube on the tips of them?

soak the lifters over nite in oil before you install them

thank you friends that is awesome video

thanks, this helped me alot. i had to get a new cylinder head and one of my valves were too short causing my rocker arm to keep falling off. will that cause your car to idle rough and not start. it ran smooth until the rocker on cylinder 5 fell off

+Paul Blakey Hi Paul, was your valve broken? Trying to figure out how you ended up with a short valve on the new cylinder head?

Thats what i was wondering. Im pulling it again today and replacing it with one of the old valves that i know works. Hopf i lly resealing the head and replacing the valve will take care of my no start problem. It ran great before the rocker fell off. Timing was spot on and fired up with a tap of the key.

+Paul Blakey Ok Man, the reason that those valves come off sometimes is because of the hydraulic lifters. Did you buy a complete new head with valves and adjusters or did you reuse your old valves and hydraulic adjusters?

+JamieJones TheCarMan i bought a new head, but i noticed one valve was shorter than the others in the new head. i checked the old one and all he valves were longer so im doing a swap right now. also going with new lifters as well.

Hey Mister Jimmy John's I followed your link to your Amazon recommendations and I didn't find the valve compressor tool that you used in this video. If I recall correctly I believe that's a Wilde design valve compressor. I found similar things on Amazon I just didn't find the exact one you used perhaps that's an aftermarket so-to-speak Fork that's attached that's actually doing the compressing on the springs?

No sir. And please excuse my auto-correct just thinks you are some sort of Sandwich King. No disrespect intended mr. Jones. I actually did finish the job, I ended up modifying a spark plug socket and the piece of bed frame in order to make a tool I can bolt to the Head apply Leverage and lower the spring in order to fit the keepers. Thank you for your videos I definitely enjoy them!

That's why you use ASSEMBLY OIL - it is sticky and keeps small parts in place .

I was told today on my jeep liberty 2010 . that the cylinder went thru the valve. should I just get a new motor. or???

That’s the safest bet

I took out the spring valves, it does not matter if i put the valves back on the valves disorderly? Or each spring needs to back on the same valve?

which side of the valve goes to the exhaust manifold, because there is a metals base in the bottom of each valve

I'm stuck doing my rebuild. The camshaft for my 4.7 heads is not turning easily while re-installing (it requires an unreasonable amount of force and makes a hard clicking sound from the springs when turning by hand. Should I install new valves? Is this a symptom of a "stuck valve?"

A little more background: I had a 2003 Dodge Dakota that seized. I swapped the engine out (thanks to KZread) with a 2000 Dodge Durango, which ran great, I just wanted the pick-up. Both were 4.7 magnums, but the Durango had a 16-tooth reluctor wheel, while the Dakota was 32-tooth. After no-spark, no-starts, I took the new-used engine back out of my Dakota. I changed it to the old 32-tooth wheel (from old engine) on the back of the crankshaft, I changed the one sprocket of the camshaft(where the sensor reads) with the old engine's since that was different also. I did something I regret during this process which was not removing the heads while turning the crankshaft about and causing the pistons to bump against the head surface. Everything else I've been following the manual to spec. I don't know if that small amount of contact could have bent a valve out of the combustion recess area, but now the camshaft is almost impossible to turn (independently off the engine block and on the block with the chain attached). It turned smoothly with little effort before. The heads may have hit the ground a few times during this re-installation. There is a lot of tension between the rocker arms and cam.

great video , but new valves and seals should be installed with assembly lube.. otherwise very good video

I love your explanations and delivery, but your camerawork :-S

You can pick one up at any auto parts store or you can hit the Amazon button on my homepage and it'll take you right there to him and you can find one there which is definitely going to be the cheapest way to go
