I own a 2008 Chevy Suburban with a 5.3 liter V-8. It is of the AFM type and I would like to know, before I get started, Does the cylinder head of either bank have to be removed to replace the lifters? After removing the valve cover to check if I had a broken valve spring, I have found that the spring is fine. My #4 cylinder lost compression and has caused a misfire or loss of power to #4 cylinder. I have done engine rebuilds. However, I have never had to dig into the guts of the newer engines. So, as stated, any info before I get to deep into my Suburban engine would be appreciated. Thanks.

No expert here but my 2007 Burb is at shop today with #6 misfire and they suspect lifter. Head DOES have to come off to get to lifters. I have a thread below I started this weekend.

 

Wow, they must have really changed the architecture of the Chevy v8 since the small block 350 days. It used to be that you just needed to remove the intake manifold and valve covers to replace the lifters.

 

Thanks for the quick reply Doktrred. Wasn't what I was hoping to hear. But, at least I know now and can order a top end seal and gasket kit instead of just a intake kit. Probably end up deciding to replace all the lifters rather than just the #4 cylinder set if the cam is still in good shape. Not looking forward to breaking free the exhaust manifold/s from the heads.

 

Breaking free? Probably more like breaking off...

But with all the work your doing in there it may be easier to replace the bolts then if you didn't need to do the work.

 

If you don't have the factory manuals, I would strongly suggest getting an AllDataDIY account, you will have access to all the service manuals and latest updates. A subscription is not very expensive considering the amount of information you have available at your fingertips... 5 years of access is $30...

 

Is there a web page to go to to get the AllinDIY manuals? The price is darn good for a five year subscription.

 

Meant AllDataDIY .
