Swapping the valve seals on Cylinder #8 on my LS swapped S10 Blazer. I try to discuss the steps, why for each and offer alternatives for securing the valves if you can’t charge the cylinder with air pressure.
Me and my dad did the rope trick on an old 1980s Pontiac V8. It was a very low milage car that sat long. So the valve seals were tight from old gas. And made the valves stick open long!
I almost always just zip the rockers down on LS's when they're in something of mine. If its someone else's I'll put them at 22ft/lbs. So far so good on both ways lol
Is there a video on how you made you spring compressor. I've got a couple in my box that are junk and this one looks awesome. Thank you for all the videos
This is a great video! You shared some great knowledge. Your valves and the surrounding area look super clean compared to mine. In my engine, the valves and springs were all covered in oil. Is that normal? I know my valve seals have failed and I am replacing them but wasn’t sure if oil should normally be present all over the values.
EOIC doesn’t matter on the LS. Been doing these since the LS inception and found taken the rocker arm bolts down evenly works the best. Factory spec is 22 ft lb and I never had an issue. Beam type torque wrenches are way better than click type on smaller fasteners. Seen guys with clickers pull the threads out by not paying attention to their settings.
There is an updated valve cover for this engine. The left side valve cover has the pcv system built into it. If you buy the updated valve cover it will eliminate this issue.
I have a 98 camaro that I’m swapping the cam in. I have 806 heads with older style valve seals where the seat and seal are separate. The cam kit I ordered came with the top design valve seal and I’m wondering if can use the top hat style with out issues, or should I just order older style seals?
Probably a dumb question here but I would like to use the air compressor method to hold up the valve seal. I cant seem to find a hose or the right fittings for the spark plug hole to make my own hose. The auto parts store guys haven't been able to help me. Can I buy a cylinder leak down tester for this use? Any help would be appreciated. Thank you.
question, im going to change all my valve seals while its in my suburban. i have the correct tools including air hose etc. Now when you say start off on number 8 and you have it tdc. you then have to remove rocker arms and rail.. but after changing valve stem seals i want to move down the line and do the rest. How do you know the next piston is at tdc without the rocker arms on?
