| Quote (miller19j @ June 09 2003,8:35 am) | So I am not supposed to run gaskets on the logs. Do I put RTV or something on there or just bolt them on straight? My logs have a water cooled flange so they are a little different than the Nickson type that just cools the log portion. They had gaskets on there when I pulled them apart so I assumed that I needed them when I put it back together. It just seems kind of strange to bolt them directly on.
The lifters are currently loaded at 1 turn should I back them off to ½? Or is it ok where it is?
When I get to the bottom of the noise and get it fixed I will open her up.  
Thanks for the help |
Ooops, should have mentioned about your setting, 1 turn is fine, no need to redo it now. The logs were made to be installed without gaskets just like the factory did, the reason is because just like the logs will warp from squishing the gaskets, the cast iron manifolds won't warp, they break that's the reason for no gaskets. But for them to seal good, the head suface must be true and no corrosion, most people don't think about that when they take the heads in and I've noticed that none of the machine shops ever ask if you want that area surfaced, at least they have never asked me!. BTW, NO silicone. If you have gaskets on there now, don't worry about it leave em there, just be very careful not to overtighten them and don't forget, as the gaskets compress, the manifolds will loosen some and you can tighten them up again and that's how you can eventually warp the the gasket surface!..

If that checks out OK, take a socket extention or anythig you have that can be used to simulate a stetascope and put it up against the valve covers, if it's a liter(s), you will hear it. If it is lifters, run the valves again. Take note of each one to see if any are loose(they should all be a half turn past zero) and if you find one loose, if you use stock nuts check the interference, if it turns easy then you need to change it. Now the pisser, if all this checks out OK, do you get this clicking sound when the motor is cold or just after running the shit out of it and the oil is hot???. If so you may have cheapie lifters, that's very common. The tollerances on some of those are way out to lunch and you get excessive blead down at idle when the oil is thin from heat. Your oil pressure is more than adequate so that ain't the problem. Let us know what you find!..
