[Fot] TR6 Dip Stick Tube

Fri May 13 20:00:55 MDT 2016

My Spit did it too. I got the meatball flag so many times from oil on the headers that it was ridiculous. Got so I'd look for it every lap. 

At first I tried a spring to hold the dipstick down tight in the tube but it still leaked. Then I tried to cap the dipstick tube with a silicon plug and a silicon cap and held with a clamp but that leaked too. 

The solution on my engine was not with the just the tube or dipstick it was in venting the engine better on both the top and bottom end and adjusting the spring load of the split on the dipstick.

I added a 1 inch ID hose venting the oil pan at the old mechanical fuel pump opening and added a 1/2 inch ID hose to the valve cover so along with the stock existing 3/8 inch hose on the valve cover I ended up with 1 7/8 inches of hose vented to the required catch tank.

I also bent the split on the dipstick so that it was harder to pull out of the tube and I replaced the felt gasket.

Extreme venting and spreading the dipstick cured the oil out the dipstick problem on my engine and probably has helped avoid pushing oil out other places. Plus the engine isn't having to overcome any buildup of bypass gas pressures on the bottom. I hope. 

Nice that the dipstick is still there for checking the oil and I don't have to go look for it.

Plus I haven't seen the meatball flag in awhile.

They all have plugs instead of dipstick tubes and I have a square drive socket and specific length extension and shorty ratchet which work perfectly to pull the plug and check the oil whether the header is red hot, cold or in between.

My race car has headers (which are in the way), an oil cooler, Accusump, remote oil filter, baffled pan, an oil pump with a filter screen, exterior (steel-braided) plumbing a street car does not have (and which has its own special wrenches), and 7.5 quarts of not-street-legal synthetic oil. Not gonna get married to a street-car item like a frickin’  tin tube sticking out of the engine block.
