Guest Nigelstephens Posted July 9, 2006 Share Posted July 9, 2006 Started to notice some oil on the fins of my Sport 1100 injection 97, and cleaned it up. Within a 300 miles it was back and dripping on to my boot. I investigated further and it is definately coming from the head casting on the RH side, just next to where the pressurised oil feed attaches to the head. Its not leaking from the pipe joint but from the alloy plugs that have been soldered/cast in to the holes that have been left by the manufacturing process. There are two of them, one either side just above where the pipe enters the head. They presumably were machining holes/casting holes that have been plugged with alloy. Is my problem unique? Any ideas on how to fix? I guess I need to drillout the plugs and and tap for some bolts and use a sealant. Could even use epoxy resin. Link to comment Share on other sites More sharing options...
Greg Field Posted July 10, 2006 Share Posted July 10, 2006 Check the crush washer that seals the hole for the access plug to the short inboard cylinder stud. Link to comment Share on other sites More sharing options...
pete roper Posted July 10, 2006 Share Posted July 10, 2006 Start with Greg's idea, replace the o-rings under the blanking plugs. If that doesn't work then clean the area thoroughly with carby cleaner or some such and just cover the bungs with a dob of epoxy and allow to dry.

Greg Field Posted July 10, 2006 Share Posted July 10, 2006 Yeah, o-rings. My head's stuck in Eldorado-land, I guess. Link to comment Share on other sites More sharing options...

Any ideas on how to fix? 94528[/snapback] Had a very similar problem with a Cali a few years back - definitely a porous casting on mine - not a lot of oil, just a very fine mist - perhaps no more than a few drops on a typical ride of a couple of hours, but it still made a mess. I was told that it could be remedied by removing the head and after cleaning meticulously, putting some special stuff (can't remember the name) on the inside. I thought that would be far too much trouble so I took to pushing a piece of tightly folded toilet paper between the fins at their root. It stopped the oil dribbling and only needed to be replaced every few weeks. Eventually I got some liquid metal and after cleaning the area externally with brake cleaner, I applied the liquid metal with a cotton bud. That stopped the leak permanently. Hope this helps.

mike wilson Posted July 11, 2006 Share Posted July 11, 2006 Loctite and Devcon make products specifically for this purpose. In the small block workshop manual, the block of Devcon putty is the No1 tool listed...... mike Link to comment Share on other sites More sharing options...
