    How long did it make the noise before you repaired it ? My 97 has been intermittently making a fidgeting sound from the back side of the motor for a little while now. Checked it out last weekend and placed a stick against the cap and you could feel the vibration pretty good while it made the...

    Mine (97 5.7) set the P0102 and a C0507 this morning. I erased them and all was good till tonight. I've been driving it all day and no re-occurrence. Now it sets a light immediately after I clear it. I unplugged my MAF this morning to replace the low side a/c switch, but it's plugged in good...

    fitting size at oil filter housing to eliminate oil cooler lines

    Hmm. OK, I'll check it out when I have it off and see about removing that. It doesn't have to flow through that bypass to circulate the filter does it ? If it doesn't then I may leave it alone if filter flow is unaffected. Thanks

    Intake Gasket Replacement

    Yea, mines dripping off the brace running to the bellhousing. It's also dripping onto the front diff from somewhere but it's dry all around the heads. My oil looks good and extremely little to no moisture in the oil fill tube.

    How to Replace oil filter adapter gasket & o-ring

    What would be the harm in this ? I bought a 97 recently and the radiator is leaking, oil cooler lines have evidence of a leak, and the cooler adapter housing is leaking. I'm considering getting a radiator with no cooler and plugging the holes in the adapter housing. I have a Duramax to pull/work...
