i need to redo my valve seals and want to know if brands or material matters? which one s to get?

also, i was told that i have larger seals but was never given the sizes. so, when i order the seals do i order for stock valves or what?

i don't know if stock valves have the same diameter posts as a "larger valve" posts.

Re: valve stem seals (?)

If & when you remove your springs to replace the valve seals, wobble each valve to check for valve guide wear. If it is excessive you will need to remove the heads to have a machine shop install new bronze guides.

Do you know which valve seal is bad? Pull each spark plug out to find if it's on the intake side. Chances are it's one of the exhaust valves.

IMO replace them all. The o-ring themselves get dry and brittle with mileage and time. Even at 60K miles and the age of our trucks, they may all practically break off trying to remove them.

When? I don't remember receiving any texts...you have to remember I have 2 kids in diapers and have had some sleep since then.
Last text I got was about the the turbo leaking oil & I told u it could be the causing the smoke & not the seals.
Are you going to pull the heads off or just the valve covers? I have the special tool to remove the springs either way on or off the block.
LMK if you need them, each rocker should take about 5 mins.

Re: valve stem seals (?)

do any of you guys think that me using royal purple could be A reason to the speedy death to the valve stem seals? it's my daily driver and i've owned for 2 years now and i've only gotten to drive it maybe 3/4 of that time.

don't really get on it too hard but i do get on it from time to time for that quick adrenaline rush.

the reason i ask about RP is i know some guys like it/use it and some guys don't like it. just thinking i should try some other oil. any comments will be greatly appreciated :tup:

Consider it lucky you got to drive it 3/4 of the time you owned it!:tup:

How long has is it smoking? A little along the way or all at once? If just a little along the way and slowly started getting worse it may be your seals, like your are thinking. If it just started and is getting fairly noticeable you may have broken a ring land. These trucks are nortorus for that.

ring land!? i don't even know what that is but it sounds like trouble.

it's been smoking for about a month now but i've only driven it for MAYBE 3 weeks while it's been smoking. started one morning to take my daughters to school and i didn't let the truck warm up and it started smoking. very little but noticeable. my DD so it eventually got worse.

Re: valve stem seals (?)

I learned a hard lesson on valve stem seal. i though i had a bad seal on num 4 cylinder. i tryied to putting air into the cylinder and had a excisive leak from an exhueast valve. so i would reccomend doing a leak down check on all cylinders making sure you dont have another problem like i did. NOW im doing a L35 convo. this all started with a junk distrubitor. FML. oh well ill have one sweet truck when im done.

I got a kit from Hood, it only came with 6 umberla seals, an old school hotrod trick is to install umberla seals on all valves. So i bought GM ones and got the new upgraded ones but they are a pain in the A$$ to put on ended up distroying one bad and im good at motor work. So my advice is to pull the heads. pluss its a pain to do it on the truck i think its faster to pull the heads.

Best of luck.

pcv valve hose to air intake after filter is dry. i didn't take a picture of #1 plug because of the atr headers. have to back it off the head to remove plug. socket won't fit between header and plug. need to put on the lift and remove it from underneath plus, it's been parked at my house 'cause i'm not driving it. so all this werk is being done in front of my house.

Re: valve stem seals (?)

That is no valve causing your #6 plug to look like that. I would bet you have a broken piston. Start your motor, open the oil fill cap, put your hand over it, if you getting pressure, you have problems.

Wow, 5 and 6 are in rough shape... definite hard detonation on #5.... I would sure say piston/ring damage.... may as well start yanking it apart. That much oil/plug damage is a sign of internal damage.
