[superjeep]

I dont know about sizes? but you don't need to order them go to advanced or auto zone there cheap as hell.

I used umbrelltype seals for the 472/500u in caddy engine on the intake valves and the o-rings seals as well .
the o-ring seals are tricky to put in {your first time }
compress the spring and retainer put the o-ring on the valve stem .
use a pick or small flat screwdriver to get the o-ring into it's groove
{the bottom groove on the valve } install the keepers add a couple drops of oil to the stem and slowly let the spring up making sure the retainer does not fold up the o-ring . :D

[rscamaro_306]

so i dont need to take the spring off. if not do you know of any websites i could go to with good pics on how and great derections. im a first timer with the valve trane stuff so i need as much help as i can get. thanks for the info.

Yes, the spring has to come off to put an umbrella seal on.

[rscamaro_306]

Yes, the spring has to come off to put an umbrella seal on.

ok so do i have to pull my heads or can i do i with the compreser and leve the heads on. and can i get an umbrella seal at advance or autozone. or do i have to order it

[UPdragracer]

doing this job with the heads on the motor sucks , but at this point you need to learn LOL!!!!
it is easy just do your job over but do it right ! I'll give you my cell # so you can call when you are doing it , if you have any questions while it is apart :D

[rscamaro_306]

if anyone els whants to put there 2 cents in on this your more than welcom. little tips or tricks to do it or what not. im perty much set but im always lisening to people. im here to learn.

[brommosauto]

What did you do about valve hieght and pressure?

[UPdragracer]

What did you do about valve hieght and pressure?

LOL!! it is not a high rpm race engine , low lift stock stuff summit springs
sheesh just a slight upgrade from stock , no need to get into spring height's or installed pressures .

let the kid learn a little at a time , the simple stuff like knowing how to assemble what you have is more important to him now .

I'm sure your fist engine was a perfect example of detail :D

[rscamaro_306]

What did you do about valve hieght and pressure?

ummmm i dont understand. like i sead im learning. i did put a new cam and 1.6 full roller lifters in and crancam valve springs. there stock sizes gust new.
like i sead im hear to learn so teach me somthing. if u dont minde.

thanks but i think its a perty good lift. for stock heads its .465 lift with 1.6 full rollers i think i was told that makes it like a .496 with all the math worked out. correct me if im wrong. but yea i got down how to put it together and all that perty good. me and my freand had tho motor compltly out of the car during school and we put it back in with the cam and new timing chane that i put in all my self and it started right up. after we found the ground wire that we forgot to ground. kiked our butts for a week couldnt get it to turn over till we found that ground.

[UPdragracer]

I just mean low lift cams as being under .550 lift or so I have built .750 inch lift small block chevy's that run pretty good {to this day } so yes spring height are important when you have big dome pistons and 3/4" lift cams hanging he valve open for 320 degrees or so
YES DEFINETLY CHECK EVERYTHING when you want a performance engine :dance:

[badass88gt]

You still need to set the springs to a specific IH to get the proper pressure, IMO this is something that should be done on any build, it's not hard to learn to do it.

well in that case im lising. teach away. im here to learn.

[badass88gt]

Well, did they tell you spring pressures for the cam, and what installed height to set those springs at to achieve those pressures?

Valve springs and seals are a piece of cake to change on the engine. Do one cylinder at a time and make sure the piston is at top dead center in case the valve should fall. This will prevent the valve from falling into the cylinder. Use the proper valve spring compressor and you should be able to do them all in a couple hours.

ok sounds good thanks for the tips. i have the compresser that mounts to the stud. is that the right tool for the job. it worked to put them in.

Yes, that compressor will work.

[badass88gt]

Whats the pressure of the springs? Does it say something like 130#@1.800" or something like that? What part number springs?

He has it here but have to figure out which one it is seeing there are three different springs listed.

[rscamaro_306]

yea i dont know which one it is. my car is a 1991 305 but i have the old stile solid lifters and not the roller lifters. and with a .465 lift cam. so im not shere what spring it would be ill look at the box and stuff....
nope box dosent seay anything. all i know is there stock diamiter springs so they might be stock but gust cran springs. i hope all the info i gave helps.

-jake

[rscamaro_306]

could it be that only the exhaust valve stem is leaking. becas it only smokes blue when its wormed up. and the umbrela gose after the ruber o ring right. i got the parts today. 25 dollers for fel-pros at autozone.
thanks
-jake

[1fastdeuce]

Put the umbrella on, then the spring and retainer, compress the spring and retainer, install o-ring on second grove and install locks on top grove. Release spring.

[rscamaro_306]

oh ok thanks that is gust what i needed to hear. thank u a lot. now do u think i need the intake ones if it only smoks blue when its wormed up but i think i only need the o ring if anything becas the umbrelas are on there good they dont come off. and there is no o ring on the second nock after the spring locks where the o ring should go so i think that will be easy. thanks agean.
-jake

[rscamaro_306]

well two valves to go. i started yesterday and got 4 valves done in 15-20minites. now i only have 2 left and iv been gust taking my time with this becas i would realy like to take my car to rapids tonight. thanks agean for all your help.
-jake

[UPdragracer]

the intake valves would be the ones sucking in oil , when running , bad exhaust valve seals will give a big puff of blue smoke upon startup :hello:

[rscamaro_306]

well i got it done and didnt change the intake valves and it smoked for a bit and then i let it cool down an it dosent smoke anymore. i changed all the o-rings becas there were none.
