Charly,

Once again, thanks!  For the others on the list, Charly had been great at helping me with some other questions.   On the external oil manifold, Chuck Gee has reached out to me separately as well as Jake Jacobsen.

Great points on the oil pump.  Steve Yott let me know he is no longer making his oil pumps which were primarily for the TR4.  So, am looking at the Racestorations oil pump/baffle combination.  Even with it, cleaning up the castings and checking the tolerances is a good idea.

Thanks again!

Regards,

Mark Cook

On my TR6 race motors (I’ve run 133 events, about 10000 miles), I never ran external oil lines and only experienced rod bearing problems twice, both were not associated with starved bearings, but builder error.   I don’t recall ever having a main bearing failure. 

 I’ve never seen a manufactured oil manifold, most I’ve seen are put together with a bunch of tees.  I think it would be easy enough to weld up a manifold out of pipe and fittings.

I think attention should be paid to the oil pump in particular.  

I’ve taking mine and cleaned up the castings to flow smoother and have checked all the tolerances to make sure they’re with in spec (blueprinted), there is someone who is offering blueprinted oil pumps for the TR6 and maybe a gasket between the oil pump and block would help.

Inquiry about oil system for TR6 Race Engine.

Seems like this guy is a candidate for FOT.

Joe,

Thanks for the follow up.  Actually, it is an auxiliary external oil system for the main bearings.   I am exploring this as I understand the main bearings in the TR6 do not receive adequate oil flow in race conditions.  I currently have a BMW Spec E46 330Ci which has a robust engine and oil system.  So, the TR6 race engine is a new project for me.   I owned a ’70 MG Midget and ’70 TR6 “back in the day”, but were street driven.

Attached are excerpts from the most recent version of Kastner’s Triumph preparation manual (pages 130-135).  I included the section on oil pumps through oil sump.  In the book, there is a discussion about the external distribution hoses on the GT6, he mentions that he “stopped all oil from going to the normal openings to the main gallery”.  Also, I understand the black manifold in one of the pictures “meters” the oil flow.  One of the pictures shows a feed line (the large black braided line) as going to the accusump.   It is this black oil manifold that I cannot find a source or enough information even to ensure constructing it properly.  I want to avoid simply having a tube with fittings made, then find it does not work as intended. 

With regards to an oiler for the rocker arms, I see that there is heavy debate in most of the forums, many implying that it would starve the main bearings.  There seems to be no consensus.

Anything you can provide would be helpful.

Thanks again,

Mark Cook
