Head Gasket Replacement Timeline

[skloczko]

Hi, is there anyone out there who could recommend, or has heard of an appropriate time to replace a head gasket on 4.0 SOHC? Not having problems with it but will have it out of the vehicle, at 100,000 miles approx.


Thanks!

Head gaskets don't have a service interval. The only time you replace them is when they go bad

If you're into preventive maintenance, think about changing the timing chains unless that's why you're pulling it in the first place.

I agree with definitely replacing the timing chain guides in the front and rear. If the engine is going to be out might also consider replacing the intake gaskets as well. If you decide to pull the head, might as well get a valve job, however, only if you go forward with replacing the head gasket. Which I don't think you need to do unless you are having issues.

head gasket and timing

In order to remove the head on a SOHC V6 you have to remove the camshaft sprocket retaining bolt. That means retiming the camshaft. The camshaft timing tool kit costs about $200.
