I've got an '88 S10 with a 4.3 it's a vin z.
I'm looking for info on installing the seals. I used nylon rope to hold the valves in place once when replacing a sheared set of keepers, and I have a compressor, so that much, I don't need to know.
My questions are about installing them, which brand, which type.
I've rebuilt two 350's, spent 80 or 90 hours totally reshaping the ports on a new set of heads. I'm just saying this for perspective, certainly not much for bragging rights. I'm humbled by the expertise here.
I'm no pro, but not a novice.
I'm 65 and have never had anyone work on my vehicles with the acceptance of machine work on heads and the engine block.
I've asked a simple question on two other websites and with over 200 views, the top answer is replace the guides.
That's not happening, yet that same advice is repeated, never answering my question.
I don't disagree with that advice, but this is an S10 and I'd probably need to pull the engine to take the heads off and if I break a couple bolts, this is my only vehicle so I'm not taking the heads off. I only want advice about replacing the seals. If they only last for a few years, so what they're better than the bakelite that exists now under the rocker covers.
Okee dokee.......
The engine has 288000 miles. Compression is 150. Runs smooth as a top.
I just want to replace the valve seals..... and no more.
My basic question, and my questions on other sites was this:
I've never replaced valve seals before. Does anyone have links to some decent videos showing the procedure? (yes I know it's not rocket science, I've simply never done it)
Videos I've seen are sketchy, like first timers doing the procedure. I want a more professional video with advice I can trust. That or a good tutorial or article.
Being an '88 4.3 vin z, (non Vortec), I'm assuming it requires umbrella seals?
If it does use those, I've read to leave the umbrella seals off of the exhaust side.
Is that correct?
I'm assuming O-rings on the intake and exhaust, but umbrella on the intake only?
Do they make Viton O-ring and umbrella seals for vin z heads? ........or are Viton seals only available on heads machined for positive style seals?
For the umbrella seals, is there a special tool, or just a socket........
Lots of information on the internet to fill my brain, but I haven't seen a video or tutorial that answers my questions with any confidence.
Any of you guys have advice or links to a good video or tutorial that would fill in my blanks!and answer my questions?
