iana Posted September 16, 2019 Report Share Posted September 16, 2019 I'm in the process of reinstating the engine block breather pipe - I need to locate a couple of gaskets (124954), a baffle (128870) and the mesh wire infill (129101), I assume that these parts are long out of stock, the gaskets I will make using gasket paper, the mesh infill is a coarse wire wool, any ideas on the baffle plate - I am thinking about making one out of a thin plate (copper or aluminum) and drilling a series of 1mm holes. Another idea is to use something like:- https://www.ebay.co.uk/itm/30-Mesh-304-Stainless-Steel-Woven-Wire-Cloth-Screen-Filtration-Filter-5-9x11-8/233289109162?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D40732%26meid%3D4113251464b8478a895de27247bf9da4%26pid%3D100005%26rk%3D6%26rkt%3D12%26sd%3D303132774901%26itm%3D233289109162%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100005.m1851 This would then be bedded in a hylomar or similar sealant and fixed to the block. Open to suggestions. Link to comment Share on other sites More sharing options...
68vitesse Posted September 17, 2019 Report Share Posted September 17, 2019 Is this a 1600 or 2L?. Regards Paul Link to comment Share on other sites More sharing options...
iana Posted September 17, 2019 Author Report Share Posted September 17, 2019 I’m fitting it on a 2l early Mark 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 17, 2019 Report Share Posted September 17, 2019 The mk1 2ltr had this blanked the 1600 has the tubed low level breather Dave would know more about the evolution but I would expect a mk1 to had the port blanked and semi sealed breather and smiths valve on the inlet manifold ????? Do you have gauze filled oil filler cap or semi sealed one ?? The low tube breather needs a filtered breathing filler cap the smiths valve has a semi sealed cap filler Pete Link to comment Share on other sites More sharing options...
68vitesse Posted September 17, 2019 Report Share Posted September 17, 2019 I have a very early small bearing 2L engine, not currently in use, this has as Pete says the block breather point plated over and the smith valve arrangement.

Pete Lewis Posted September 17, 2019 Report Share Posted September 17, 2019 Iana , So now we need the engine number ??? Pete Link to comment Share on other sites More sharing options...
iana Posted September 17, 2019 Author Report Share Posted September 17, 2019 The engine has a blanking plate currently fitted, however the car is fitted with Su carbs with a very odd breather set up, my plan is to vent the carbs into the rocker box as per a spitfire, use the crankcase breather from a triumph 2000, and remove the smiths valve arrangement. The manifold take off will then feed the brake servo. And as a final adjustment I will revert to a near standard air box setup (I’ve got an air box that will fit on the su’s) Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 17, 2019 Report Share Posted September 17, 2019 then you still need the port in the crankcase being blanked or its will just suck air thro and over weaken the carb mixtures the idea is is sealed witha light vacuumed extraction into the SU carb bodies i had a couple of local Vits with SU and all ran better when reverted to Strombergs and correct needles pete 1 Link to comment Share on other sites More sharing options...
dave.vitesse Posted September 18, 2019 Report Share Posted September 18, 2019 The SU's don't vent off into the crankcase, it's the other way around. The SU's maintain a low depression in the crank case. i.e. Closed Circuit Breathing System. This is why the crankcase breather is blanked off.

iana Posted September 18, 2019 Author Report Share Posted September 18, 2019 Dave thanks for that photo, thats a similar setup to what I had on my GT6, so in theory I can connect the carbs to the ocker box as the photo. and then the servo off the manifold? 1 Link to comment Share on other sites More sharing options...
68vitesse Posted September 18, 2019 Report Share Posted September 18, 2019 I used a 16mm Banjo fitting and a 5/8 unf banjo bolt in the smith valve take off point for my servo the second banjo is for the valve. Regards Paul 1 Link to comment Share on other sites More sharing options...
