2000 Yukon 1500 with 5.3 bad head gasket and more.

[RestoreAmerica]

Hello,
I acquired this vehicle and it appear to be worth fixing.

Bad head or gasket. I just ordered a set of remanufactured heads.

While I have this torn apart, what else should I do to the motor.

Vehicle had noisy lifters but also had bad head gasket or cracked head.

I don't want to spend more than needed but don't want to tear it apart in 6 months to replace something I could easily replace now.

I have not gotten the heads off yet. Almost there. I decided better just purchase heads for $300 than to just put gaskets on the old ones. These are the head I purchased http://www.ebay.com/itm/201358045312...%3AMEBIDX%3AIT

Would you replace the lifters or just clean them?

Any advice is appreciated.

Thank you!!

While you have it apart:

I would totally buy and install NEW lifters, they are available on ebay, genuine GM parts for 120$ a set. since you have the heads off its a simple matter to install the new ones. I always buy the new lifter guide things just because safer than sorry.

obviously head gaskets and intake manifold gaskets.


while your at it, because it is recommended while accessible, knock sensors, and if it was me, i am actually going to be doing lifters in my wifes truck here in the next month or so, i am also going to change out the cam position sensor. and i would do crank position sensor while all the top of the engine stuff is off the crank sensor is just above the starter.

It can be FUN!!!! lol
