So tomorrow I'm changing my LIM gaskets for ones that aren't leaking...imagine that. I know ideally the RTV that'll go around the valve cover gaskets need to cure for 24hrs before it's ready to go, but is it safe to let it sit for 6-8 hrs then drive it real nice and easy for about 45 minutes? The work is being done at my parents garage, and eventually I need to get back home for work in the morning.

Thanks

The RTV needs time to cure , you can't change that . Is it worth having to do it over because it didn't seal ?

It should seal within an hr. I have never had it sit for 8+ hrs with a problem.

RTV sealants are aerobic, which means they must be exposed to atmospheric oxygen to cure in place.

To reliably seal metal-to-metal joints, RTVs must be applied to clean, dry surfaces and allowed to cure before the vehicle is placed in service. Chemical gasket removers and aerosol solvents like brake cleaner can be used to prepare the surface for an RTV application. Without adequate surface preparation, formed-in-place RTV gaskets can be a gamble. That said , do whatever it's not my car .. :)

This is H.O. Driver, Not Dave ;)

that is what I figured, since the dealer gives the car back right after its done sometimes anyways. We just didn't know what other people had luck with. Good to hear though, thanks guys. :thumbs:

lol Miller= pi$$water lol j/k

Yeah it should all go smoth Just inspect the number 5 exhaust rocker threads. Put the right Rod in the right rocker (I dont knwo how you can **** it up the intake and exhaust rocker rods are diff lengths)

and if you can Detach the fuel rail down below, its just a clip, if you do it up top you have to unbolt it ;)

#5 sucks.

But I have been lucky and had no problems after I have done like 8 LIM gaskets.

Gt00, I always clean and prep the surface first. Here are 2 before and after pics of the clean job I do

Before:

You can still see some oil on that pic, I took that pic to show how clean the valve springs and stuff was. But I went back over that again and made sute it was even more clean then that.

Another question...Does the power steering pump just unbolt and pop off? Is it just the bolts behind the pulley or is there more to it?


Thanks for the pics too

Gt00, I always clean and prep the surface first.. That's what you want , i've seen oil leaks between the RTV and the metal because someone rushed the prep work and left oil on there . May not happen right away , but later on guess what ? WRONG do it again ! lol

Once you take the belt off all you need to do is line up the Holes in the pully to the bolts, kinda hard to see but what I did was slide a 10mm (I think) in to the hole with and extention and just spun is slowly untill I lined up with a bolt, there are 3 in total (I thinkO

its 3-13MM bolts. Take the belt off and the motor mount off, then spin the pulley till you get the 3 bolts. You do not need to remove any lines, just move it out of the way.

A few more pics of how nasty this was:

Hey 95-GT, was it the coolant that made those springs get gummed up so bad?? or did someone not change their oil or something? That cant be a normal amount of gummy junk.
