okay, that was strange. was getting rexed, but as soon as I posted the image in my post, i could see the image in your first post...

A question for anyone who has done a valve spring change with the heads on, using the compressed air method.

Can the valve stem seals be changed this way without risk of the valves falling in :?:

It would make sense that they could.

Well, with the valve seals out the air has an easier time getting past the valve? right?

I sure hope not, The valves should seal against the seats. The stem seals are more for oil control.

yeah, it works great. i haven't done it on my SII, but I did with my 82 cutlass (231). works like a charm. the seals on mine were bad enough that there really wan't a difference between having them on and off as far as the compressed air was concerned, and back in that day (the 82 231 that is), the exhaust valves didn't even have valve seals...

so yeah. it works great.

TIP: Use mechanical parts lube on all moving parts.

Mine ticked for a couple minutes after each start for 2 days, so don't let that alarm you if it happens to you.

Otherwise looks sexy, retainers and pushrods as well?

Allmachtige - Yes, INTENSE 1.9 Rockers, LS6 90 lb Springs, OR Pushrods, Titanium Retainers, Viton valve seals, and HP valve locks.
The pushrods are laying on the rocker cover gaskets in the pic. The retainers are in the Comp package just to the left of the pushrods.
Those titanium retainers sure are light.

So simply using motor oil on all parts during assembly is not enough :?:

We've never lubed anything during valvespring/rocker swaps and never got a tick. We've done 4 swaps that I can think of, only 3 of which had valvesprings (the SSEi has stock valvetrain besides rockers) We've never changed valve seals, but other than that we've changed all that, and we haven't even ever put oil on them. Never had any ticking problems or anything. I think lubing them with oil will be more than enough.

I lubed everything with mobile 1 engine oil and gave the assembly a few squirts before buttoning up the valve covers. I had no ticks at all, smooth as could be.
