    I just pulled the valve covers for the first time since owning the truck...It was leaking oil from them pretty badly...the covers came off easily but usually somegasket stays attached to them of partially attached or it is still easily removed from the heads....

    This truck different story...they seem to be cooked on there and I am having great difficulty getting the surface clean again. I actually thought for a moment there was no gasket becuase the gasket has hardened that much to the heads. Any tips or tricks? I am scared my paint scraper will cause the sealing surface damage

    CAREFULLY spray some BrakeKleen on the sucker and let it sit for a little bit, then attack it with a gasket scraper. Make sure you cover your heads and oil drain holes with a rag because if the BrakeKleen gets into your oil it will break it down in a hurry!!!!

    BrakeKleen is that a special brake cleaner or will any old brake cleaner work? I plan on doing an oil change this afternoon anyway

    That's just the brand I use. For all I know, you guys south of the border might have never heard of it........

    Just try your best to keep the brake cleaner from dripping into the oil passages. Even if you plan on changing your oil, there might be some residue that will contaminate your new oil. It odesn't take too much of the stuff to break down oil.......

    If that doesn't work you can always try some WD40, too. Chances are that you'll have to use some elbow grease.......It sounds like that sucker is gonna be tough to remove.

    Good luck, brother!!!![​IMG]

    One hint.......if you have AC it's alot easier to get the right cover back on properly if you undo the compressor bracket.......

    Sorry to hear the job has been so ugly.
