[TR] Oil Pan Sealer?

[DAVID MASSEY]

 Which should he do first?  TR3/4 or TR6/GT6.  Or maybe the Spitfire.

Subject: Re: [TR] Oil Pan Sealer?  A couple advisories about using RTV that I have picked up over the years.    Not all RTV sealants are the same.  Some are oil resistant and others are not.  "Automotive" RTV may not be oil resistant and are intended for sealing windshields and such.  Check the manufacturer's website.  Ultra Black, I believe, is oil resistant.  None, as far as I know, are gasoline resistant.  When  using RTV sealants, apply an even bead and assemble the parts loosely and let the sealant partially set before tightening.  This will reduce the tendency for the sealant to ooze out strings and dingleberries which can clog the oil passages in the engine causing all manner of expensive problems.  When using RTV in the absence of a gasket lay a piece of thread or string along the joint to prevent metal-to-metal contact ensuring that there is a layer of sealant at all points along the joint.    As for me, I prefer to use Formagasket #2 on one side to stick the gasket (more or less) permanently to one part and Hylomar non hardening to allow for easy removal/resintallation.  Until Joe Alexander produces a silicone sump gasket I will continue to do so.  ;-)  Dave     -----Original Message-----

Subject: Re: [TR] Oil Pan Sealer?I have had good results with Permatex “Ultra Black” gasket maker. Part # 82180. I seem to remember that years ago, there was only Permatex #1 which was hardening and #2 which remained slightly pliable. Now, it seems that there is a gasket goop for white cars travelling north with 6 cyl. engines, a different product for dark color cars travelling east with 4 cyl. engines,  etc., etc. The choices on the rack at the local NAPA store can be overwhelming, just like the varieties of Loctite that you can buy. I have found that many gaskets for tractor restoration are no longer available from anyone and that the gasket-in-a-tube is the only alternative. Sometimes, it is one casting being sealed against another casting – in those cases, a very small bead is needed. When there is a pressed steel cover being assembled to a casting, you know that there will be much more of a chance for a warped or bent interface which will require a thicker bead. But we all know that many engine and other drivetrain problems are the result of excess gasket goop becoming entangled into suction screens, bearings, oil galleries and other places. Truthfully, I always get very nervous when I am repairing somebody’s tractor or whatever and I see ribbons of blue RTV sealer inside of a compartment. I’m sure that many leaks are the result of deformed oil pans, valve covers, tappet covers, etc. due to a previous “mechanic” overtightening bolts. “If 20 ft.-lbs. are good, then 40 must be better” Unless you have access to a granite or cast iron surface plate, it can be difficult to determine if an oil pan is warped. Years ago when I was teaching in the shop, I would use the surface of our big table saw (all cast iron) as a makeshift surface plate when checking small parts for flatness.

Subject: [TR] Oil Pan Sealer? Replacing the TR3 oil pan after a fresh powder coating and wondering about the best sealer.  My first thought is a bead of RTV on each side of the gasket, what is the collective wisdom of the List on this?   BTW, both surfaces are in excellent condition. Thanks,BillTS30800L
