Doing this exact same job on a CP. Great tutorial. Garry. NZ.

Thanks for watching

Hi I've got my metering unit away and have decided to copy your idea if you don't mind and also put a baffle plate in the alloy rocker cover. The only thing is my catch tank won't be as fancy as yours a credit to you. Regards Kevin

[@mgmidget-thebirthofaraceca4349]

All the best. Mine came off eBay and wasn’t particularly expensive

[@kevindoddridge1326]

I ordered one today but I went for a smaller size one. Next job poly bushes

[@mgmidget-thebirthofaraceca4349]

good luck. thanks for watching

[@roselh1]

Nice! Good execution of the plan. Does it matter if a catch tank is located above or below the point of exit for fumes

[@mgmidget-thebirthofaraceca4349]

I worked on the basis that you want to avoid oil flowing down so mounted it higher rather than lower. Thanks for watching

[@wheatcroft712]

Many thanks for posting. So this would vastly help my sooty plugs in 5 & 6? Any other thoughts gratefully received.

[@mgmidget-thebirthofaraceca4349]

It might well do , but do ensure your induction is well balanced first

[@craigstearns7587]

Love your vids!! Q: The crankcase vent… does it require a bit of vacuum to operate? I’ve a US carbureted 6 and have fitted the good parts oil separator system. Manifold vacuum, pulling on the lower crank case and upper rocker cover separating oil and putting the combustibles into the intake. Manifold thoughts? It seems to me there’s a lot of vacuum, put on the lower crank case in the set up.

[@mgmidget-thebirthofaraceca4349]

the pipe from the vent is connected to the oil catch tank. relies on venting to atmosphere. no vac involved. just relieves the crankcase pressure so less pressure pushing oil out of the engine hopefully. thanks for watching and glad your enjoying the vids

[@anthonyfoy4423]

Hi, great set of videos. Could the breather on the crankcase be done without removing pump, it is a little above my pay grade!!! Thanks

[@mgmidget-thebirthofaraceca4349]

maybe but access is very restricted. much easier to lift it out of the way. thanks for watching

[@anthonyfoy4423]

I got it up on a lift and it was much easier for me. That pump just terrifies me! It now vents great and an oil leak that I had just vanished. Thanks again

[@TR4U-TAY55]

How did everything work out with the extra venting and oil catch can? Were you still getting a lot of blowby venting into the atmosphere?

[@mgmidget-thebirthofaraceca4349]

It relieved the crank case pressure for sure so was helpful in not sending oil fumes back through the induction system, but the underlying cause was the engine needed a rebuild which is now done (see other videos)

[@sammoj9836]

Greetings again, this Sam from the US. Great video. 👍👍 Will you kindly answer my questions. 1. My rocker cover had a plate that was glued in front of the breather hole. I noticed that the glue had given away and the plate was laying on top of the cylinder head when I had removed the cover to adjust the valves. -What is the purpose of the plate (similar to the one in your older rocker cover) in front of the breather hole? -Should I try to attach it again? -how much back pressure does an engine need? -Have you felt a better performance from your engine since you’ve added the new breather? -Do you recommend the retrofit? Much Thanks 🙏 Cheers, Sam

[@mgmidget-thebirthofaraceca4349]

Hi, great questions. The little plate stops direct oil splash and fumes but allows air around it so should reduce oil mist going to the induction and going back through the engine. I would refit it. The TR6 engine runs under negative pressure as the induction sucks the mist created out. All this mod does is reduce the amount of oil mist going back through the engine meaning a cleaner burn and less smog out the exhaust. There’s no increase in car performance noticeable only less exhaust smog under hard use

[@Ajptr6]

I like the thinking behind this upgrade but is there any oil smell getting into the cabin from the breather filter?

[@mgmidget-thebirthofaraceca4349]

Hi, no as the air vent is taken from the exterior grate in front of the windscreen. The bonnet seal is between this and the filter. Thanks for watching

[@prefect9777]

Is the oil catch tank essential or could one not just put a filter on the end of a tube from the old mech fuel pump point?

[@mgmidget-thebirthofaraceca4349]

Yes I guess you could just put a filter on it

[@craigstearns7587]

Curious why you decided to use a bolt and nut and not a pop rivet on the plate installed on the valve cover

[@mgmidget-thebirthofaraceca4349]

good question. no particular reason. didnt want a pop rivet to vibrate loose , but having said that there's probably more risk in the nut coming off so takes your choice. guess i just prefer nuts and bolts

[@pats-c5x]

Where did you purchase the oil catch can ?

[@mgmidget-thebirthofaraceca4349]

A popular auction website beginning with E :-)

[@andrewrfpi]

So after running this mod for a while, did you notice ant difference in running, tickover etc? Do you have any oil residue in the catch tank?

[@mgmidget-thebirthofaraceca4349]

yes a bit less smoke out the back and a bit of oil in the tank. Longer term the car needs a bottom end rebuild but for now im happy with this mod

[@michaelstoliker971]

TR6 engines will piss oil all over themselves, especially with aftermarket valve covers. Either figure out and fit a PCV system or put in baffle plates and fiber filters to allow the oil mist to condense and drip back into the engine or a combination of both.

[@mgmidget-thebirthofaraceca4349]

Thanks for watching and glad you enjoyed the video

[@bernardwarr4187]

Mine was rebuilt in the 1990’s aftermarket rocker cover and doesn’t drip a drop of oil! May be, you need to get your engine rebuild by a professional?

[@RANSOME99]

Nooooo!!! Why drill when you could Tig weld that?

[@mgmidget-thebirthofaraceca4349]

Got a MIG welder but not TIG unfortunately. on the list of things to do at sometime :-). thanks for watching

[@RANSOME99]

@mgmidget-thebirthofaraceca4349 I was just messing with you hehe. Thank you for the reply!

[@paulhall170]

Not related to your content, which is interesting (old 2000/2500TC owner) but what the heck is the constant racing car noise in the background? Please turn it off, whatever it is....

[@mgmidget-thebirthofaraceca4349]

probably background road noise . noted . thanks for the feedback and watching
