MED Engine Breather Kit

[@fariszengi]

I really hope med will make their tech open source.

I hope this has progressed to AN style fittings now, would make it look significantly nicer.

If someone is still monitoring this video, is that thermostat housing modified for the temp sensor, or is it a catalog item? I don't currently see it listed. Base looks thicker than what you show available. *Adding gauges to my A35. Thanks.

Iron Age Brit engines were : Blowby Specials basically due to Primitive Iron age designs and even Worse pistons / rings

[@truckatadders]

That's a sexy looking engine right there 😍😍

[@mesco8200]

I bought items from yourself. Diff. Then rockers, then filter and intake Paid postage twice on small items but both items arrived in same box. I requested some stickers be sent but I got no reply? Could you sort this out for me as very happy with your products

[@MEDEngineeringTechVideos]

Hi Scott, was this from March 2018? Let us know before the next bits and we'll ship FOC, include some stickers and one of the new books when they're ready. :)

I have a 1275 inline race engine in a frogeye racing in Florida USA (actually just purchased clutch and timing and balancer stuff from you, excellent quality by the way!) Can I add the billet fuel pump breather and get rid of the timing cover breather (I think they are ugly) if yes, would this go directly to my catch tank, or via the rocker cover like you have for the mini’s?

[@MEDEngineeringTechVideos]

Hi Austin, the downside to feeding this straight to a catch tank is that on hard right handers, you may find the oil surges from here as it's quite low in the engine. For this reason we'd feed back to the rocker cover and breath from there. The more breathers the better on a race motor.

[@PaulBewsher]

Hi, is there any particular reason you join the crankcase breather to the rocker cover, and then join the rocker box to the catch tank, why not vent both separately? - was it just to be tidy, or so you only need one pipe to the catch tank, or is there an engineering reason (e.g. equalizing the pressure between the top and bottom of the engine for example?) - cheers

[@MEDEngineeringTechVideos]

Hi Paul, the transfer case breather can tend to blow out a fair amount of oil, so we drain that back to the rocker cover rather than the tank.

[@FizulNizam]

MED Engineering when I did the setup of the breather going straight to the catch can, I had a lot of crankcase pressure that was building up. If I were to run it into the rocker cover, would it solve this problem?

[@MEDEngineeringTechVideos]

@@FizulNizam If you have excessive crankcase pressure with decent breathers already installed, we'd look at the engine itself. Perhaps the piston rings are worn.

Had to watch it twice, first time is was distracted by the cross flow porn on show.

[@eiriktell3972]

Hi, I'm curious how you would usually go about connecting the timing cover breather to this system? I'm guessing the best way would be plumbing it into the rocker cover like you suggested for the alternative fuel pump breather, but you haven't made a 3rd inlet on the rocker cover making me question if there is an alternative? I am also curious about fixing the catch tank under the wing, would waterspray from the tyre affect anything, seeing as there is only a little filter ontop?

[@MEDEngineeringTechVideos]

It depends what you're running as a timing cover, as many do not run a breather here. It would need to be a custom fabrication job to the rocker cover if you wish to also connect the timing cover - straightforward enough. The under-wing catch tank is more aimed at race cars so it's not usually a problem. Perhaps a plastic guard might be a good plan if you're planning on driving a lot in the rain.

[@nicolasroy7479]

Hi, many thanks for the video. I've another question about the breather from the timing cover. Where are you fitting it ? Because there isn't any hole in the rocker cover for it

[@MEDEngineeringTechVideos]

This particular engine is just a mock-up for the rocker cover, so won't be using the large breathers. Instead it will have a custom rocker cover to plumb-in the smaller breathers. On a race engine we would recommend the larger breathers, either weld an extra breather on the opposite end or run without a breather on the timing cover.

[@ronald1968]

Can anyone describe where the catch tank is fitted I just bought the kit,but it seems you need another 90deg bend to get the pipe onto the tank.....???

[@juliangoulbourne6076]

what colour grey is that engine and is it powdered coated thanks

[@cj64crosser]

Hi, just wondering🤔 moisture is produced from a cold starting engine, would this not cause a problem in the rocker tappet area? Cheers Chris

[@ROGUESPIRIT_]

putting oil back into the combustion mixture isnt good for emissions or racing...

[@rashpalsingh1029]

Why is the catch can so big if it is not intended to only catch an oil mist?

[@MEDEngineeringTechVideos]

Race regulations - you need a 2 litre tank.

[@gronno]

We have a 1275 road car, hif 38, Sw5 cam enthusiastically driven by 18 yo son. Could we route breathers to rocker cover then vent the rocker cover to the carb rather than a catch tank?

[@MEDEngineeringTechVideos]

Hi Jon, you can do. The main reason we don't recommend this on race engines is that they can breathe more heavily than a road engine, so the air is going to have a stronger mist of oil. This in turn can mess up the air:fuel ratio.

[@AntsRC]

Can u fit the 1.5:1 roller Roller rockers under the black classic rocket cover??

[@MEDEngineeringTechVideos]

Yes, no problem.

[@dodgerboiii]

Does this increase in performance ?

[@MEDEngineeringTechVideos]

Not directly, no.

[@debodevil6974]

Why would use tell people a catch tank shouldn't fill up??? Thats exactly what its there for and if use dont empty it regularly it will fill up

[@MEDEngineeringTechVideos]

If your catch tank is completely full up, there's something very badly wrong with your motor.

[@debodevil6974]

@@MEDEngineeringTechVideos Yes if u dont empty it. But it will fill up. Even more so with a modified engine. You make out in the video that it shouldn't fill up. Ive watched a few of your videos and there's a few things I've heard you say that are misleading.

[@MEDEngineeringTechVideos]

@@debodevil6974 a healthy race engine will not fill up a two litre catch tank.
