Lifter question

[zac hale]

I have 15 silverado with 5.3, I have a misfire on cylinder 7 code along with rough idle and lean on that bank. No ticking and I have low compression on number 7 (70 psi) I suspect lifter but if you have any other suggestions let me know please.  Also, what parts do I need to change the lifter on the one bank? Money is tight so I will be restricted ro doing the one side instead of both. Thanks in advance for any reply

Broken valve spring would be the other thing but less likely.

 

You will need a head gasket, 2 new lifters for cylinder 7, engine oil and coolant. New fuel lines under the intake, possible that you will need intake gasket and exhaust gaskets.

 

The GM dealer can sell you a kit with everything you need minus the lifters, fuel lines and oil/coolant. It comes with the gaskets for the job. Not sure if it comes with head bolts but you will need those too.
