TR6 TR6 Aluminum oil gallery plugs

[alphadog]

Rebuilding my TR6 engine - there are 2 oil gallery plugs made out of aluminum - one under the steel plate on the front, and one above the oil filter. The front one appears to be cut off flush with the block, while the one over the oil filter was pounded out to look like the head of a carriage bolt and the diameter is bigger then the thread size.

TRF sells a replacement for each that is 3 threaded sections on one rod - it is easy to thread the front one in and cut it off, but I am looking for suggestions regarding the one above the oil filter. I assume these 2 are AL to signify that they were not normally removed, but I have not run into anyone that has actually replaced these.

Has anyone here replaced these AL plugs and been able to make them look like original?

Well, not exactly like original, but look about 1/4 down the page:

Thanks Ed,

I may go a non original route, but I would really like to mimic the original look if possible - I had not seen this page though, so thanks for the link.

I like that fix! I like making design changes/improvements that can be reversed should anyone like to go back to complete originality.

Call up Wishbone classics and order their steel plugs. I had to replace one of the original aluminum plugs - the one next to the oil filter. Very ugly enterprise with the engine in. Short answer is that I finally had to pull the engine, drill out the plug. I then replaced it with a steel plug and then cleaned out all of the oil galleries and the main bearings as aluminum swarf had made its way into the bearings.....
