I got me a Tahoe!

I love the LED light upgrades in my SSV - getting older and poor lightening makes this a worthwhile update.

a valve spring is definitely worth checking for.

you can also try mechanically release the stuck lifter. it seems to work if it hasn't been driving long enough with a stuck lifter that it damaged the cam or the lifter holders

So.....no compression test?

So, I was going to ask. Should I check compression first you think or pull valve cover and check/watch valve spring/rocker? Not being a smart alec, genuinely asking.

 

[OR VietVet]

When you are cranking the engine over for a compression, you will get a little oil squirting if valve cover is off but if the valve cover is off, you may be able to see right away what is wrong. It's a choice because if you have low compression, you are gonna pull the valve cover asap anyway.

I would start with a compression test and go from there.
If you have low to none on that cylinder then you'll be pulling the valve cover to check the valve train, anyway.
