I paid safety clean 1200 bucks to haul off an oven at work that had Asbestos in it.  A clutch would be half that I'd bet..  SC

Back before my VW days I always added a can of STP oil treatment at oil changes.  I thought that was what contributed to getting over 100,000 miles on several GM engines I had (V8's and in-line 6's and 4's).  Come to find out, it was probably a waste of money.  I've gotten somewhere in the neighborhood of 100,000 miles on the 1600 single port that's currently in Joy's convertible, and I built it with mostly used parts.  The only thing new was the bearings, rings and gaskets.  Since it doesn't have an oil filter, I'm thinking now that changing your oil often is the major factor in extending engine life.

I don't know what Lucas will do, but I can tell you that straight 30 weight in a half worn out 1600 will create more oil pressure than the oil cooler seals can handle if you fire it up and immediately take off down the road when it's 5 degrees outside.  Been there, done that.  At 5 degrees, straight 30 weight has about the same consistency of STP . . . it doesn't flow well.  I blew out 3 quarts of oil in the 13 miles between work and home.  No, I didn't run it dry; I stopped twice and added a quart.  After the weather warmed back up, there was only a slight trickle of oil seeping from the oil cooler seals.  I don't know how high the pressure got, but if it had not of blown it by the seals, I'd bet it would have busted the cooler open.  My thinking used to be (back in my "Drive a GM product or walk days) that the higher the oil pressure, the better the lubrication.  This is not true.  As long as the oil has enough film strength to stick together and create a film of oil between the moving parts of the engine, the better it flows, the better the lubrication.  Thinner oil flows better than thicker oil.  Hot oil flows better than cold oil.  Cold, thick oil will give you better oil pressure, but it won't necessarily lubricate better.

I just caught up with this.  
   Why the galley plug blew out ?  VW told us it was the plugs fault. They were made a little to small. Thats the reason I said do not put a new plug back in. You might get the old version and have the same thing happen again.
    Blowing cooler seals ?  Several reasons. Some of the after-market gasket sets had really rotten rubber products. The cooler seals would get hard as a rock after a few thousand miles. They would either shrink up and close the cooler off or crack and start leaking. We use to order factory seals and only use factory seals. No more problems.
    If the owner read his owners manual , you would see that you were suppose to use a lighter grade oil in really cold weather and if it was a 6V car + 30w oil, You were parked until spring unless you built a fire under it or took the poor thing in the house with you. Even with all that said , you shouldn't have blown cooler seals.
    If I remember correctly, There is a little thing on the bottom of the case called a pressure relief valve. This little dude not only control'd the pressure ,but limited the amount of oil that pass through the cooler until the engine warmed up. So why would it blow cooler seals unless they were bad to begin with or the cooler itself was loose on the case or vibrated itselve apart or even YOU put the wrong seals on.(seen that happen).
   We have talked about what kind of oil to use before. VW said to use 30w in the summer, 20w in the winter. Why !!    Economy. Single grade oil were cheaper than Muti-Grade oils at that time and that was the only reason. Heck ! I did it until I learned better.
    The bottom line here is :   Good seals, Good Cooler, A pressure Relief valve that works and on the count of 3,  1-2-3-  20w50. Slam the lid and Happy Motoring !!!!!!!!
     Remember ,Its your coal truck. You can put a pile of crap in it or the proper stuff and enjoy yourselve. Your choice. \/

Heck Fire !!!   As long as I am on my soap box this morning :
               I HATE TO CHANGE OIL WITH A PASSION
        So why would I carry a 7 day weather forecast around with me to determind what grade oil I'm suppose to use today. 30w or 20w ?
Good Gosh !  Its going to be 75 degrees today and 15 degrees in the morning.  Remember ,We live in good ole' Chattanooga. Perfect weather, perfect non-corupt politics, perfect non-corupt police. I think I will use 20w-50w and forget about all of this. :lol:  :lol:

I guess you could do that although I had one of the lower rt.(like yours) come out that had JB-Weld on it. It was a mess trying to get the left-overs out of the galley. We were concerned about chunks of JB-Weld getting up in the galley where we couldn't get to them. Of course his plug had come out before and was re-used. I don't think you could smear enough Weld on the outside to make that much difference. Like I said before, I haven't seen a problem with the other galley plugs. As far as having chunks of JB-Weld getting to the clutch,I think the clutch or the flywheel would spit them out. This is something to think about though. Back when VW used the old coil spring pressure plates, they came with 3  small clips under the 3 levers to pre-load the plate to help install. You were supposed to flip these clips out after you tighten all the bolts up. If you forgot to do this, they slung out after you started the engine and mashed the clutch in the first time. Guess where they always ended up. They were hung up in the starter housing locking up the starter.(Don't ask me how I know that :lol: ) . I don't know if JB-Weld would have the stuff to lock up the starter if it ended up there. I would just fix the one  and not worry about the others. Its your call.

...and David, I should have asked about valve guides, not valve seats.  I didn't know what I was talking about.

Sometimes a guide will have a little nick at the top of the guide inside the ex/in ports

Yeah, that's what I meant.  I was talking about that when I said that I should have been using the word "guide" instead of "seat".  So wherever in my previous post I said "seat", it should have been "guide".

Yes, there is a nick in it and it looks like old, burnt ceramic...I swear it does!

Sure.  But maybe its more like a pretty lentil loaf can taste bad.

Ok, so its not ceramic.
