valve stem seal replacement? =(
- Thread starter rodama5anthony

I did my own... then I had a stuck intake valve... ruined the head. I'll always wonder if I caused it. Id get the correct spring compressor, not the redneck fix I did with the PVC pipes.

thanks man this is a big help!
I've tried redneck style and it is way more work than it's worth IMHO. I did two valves that way and it was taking longer than it would have to remove and replace the head. Unless the cost of the HG is an issue I would just do it the right way.
Not a fan of the rope trick.
Here's what I did because I didn't want to break the HG Seal: Start at post #273

alright thanks guys for all your help. im going to be replacing it wit the engine still in the car, after reading all your explanations i have a few questions:
how do i know when the piston is at TDC?
is there a specific sequence that i need to change them in?

There is no specific sequence.
TDC (Top Dead Center) is when the piston is at the top of it's stroke. You'll want to look down in the spark plug hole with a flash light to see where the piston is. Then rotate the crank by hand until the piston is at the top. Then put a wooden dowel in the spark plug hole and rotate the crank while watching the dowel. Once the dowel stops rising, you're at TDC.
Removing all of the spark plugs makes to rotating part easy.
Make sure you use the little plastic sleeve that comes with the valve stem seals. It slides over the top of the valve so the seal won't get damage when you slide it down the valve stem.

Make sure the valve keepers don't fall into the cylinder! lol that would suck.
I will be doing this soon on my 1JZ, I'll take pics.
What fitting did you use to put the air in the cyl Kenny?
Good info, I like the pvc tool too! haha

^That would suck!
I used the hose in my Compression Tester Kit. It threads in to the spark plug hole and just so happened to have the right air fitting. Yeah, the PVC tool was kind of ghetto; but, it worked.

thanks for the info guys. i have a air compressor so ill be using that to keep the valves from falling in the cylinder and ill be sure to have a magnet handy to get the keepers after i compress the springs
anyone know how much the head weighs? i was thinking about doing the headgasket to make sure it not blown
A complete assembled head weights about 80 lbs
I have a good head FS, pm me if you are interested.
