	I want the water flow from the heater circuit to always flow back to the engine, whether the heater is on or not. The engine needs this as a design fault means cylinder 4 doesn't get adequate cooling. Ie I don't want to stop the flow back to the engine when the heater is off. I could just T off a permanent circuit for the heater but would prefer to have the heater work well in winter. So, is there a source of cheap three way valves out there that deal with hot, pressurised water? Best I can come up with is 3 way central heating valves but these have 240V electric solonoid rather than manual lever & I think use a rubber bung to control flow rather than a chrome or stainless steel ball valve. They also cost about £50. Other alternative is two 2 way valves and remembering to turn one off and one on. This is somewhat clunky though. Any suggestions? many thanks

	the ford KA might be worth a look, i think it's 4 port so flows through the valve to the heater when on, but bypasses when off and fluid still circulates via the return hose, control is electric, might be plain on/off but if you used it in conjunction with a flow valve and put a micro-switch to close the valve when you select cold it could do the job cgi.ebay.co.uk/Ford-Heater-solenoid-valve-/120740073495?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item1c1cab5017#ht_500wt_1156 I've heard of people using them on other cars, but also a chap in the trade claimed they only lasted typically about 10yrs on a KA, but on the flip side not expensive either.

	Danfoss HSV3 mid position valves for central heating are available ad the valve only without a solenoid. also the part that controls the water flow appears to be spring loaded metal plates. you can get them on ebay for less than £20 inc.postage. just happens that I've got one to change on my central heating

	basically you are looking at putting in a primary/secondary return similar to what we would install in a hot water system,which involves a tee piece as close to the heater matrix as possible,this will allow the flow of hot water in your case to flow freely around the system,you could use 2 10mm tee and solder 3 tails in each end and install 1 in the flow,1 in the return,then this will allow the circulating water to by-pass the matrix,then when the demand for heat is required the flow will divert through the matrix,its a cheap method to try as most 3 way ports require some form of power to operate.www.google.co.uk/url?sa=t&source=web&cd=2&ved=0CF0QFjAB&url=http%3A%2F%2Fwww.seascrew.com%2Fbrowse.cfm%3FFUEL-VALVES-2---3-PORT-MANUAL---ELECTRICAL%26l%3D0000000767&ei=-gT_TaXAJoWzhAf8trWcCw&usg=AFQjCNHi4VDr7asU5U9P66Z4ww_drxQoaA&sig2=oqK-vojJP-5Y89m2MEjHpQ try this link they have a manual 3 way for under £15.

	That's brilliant, thanks guys. I was thinking central heating but couldn't find the 3 way for less than about £45 which is a lot of money to spend when it might not work as an idea.

	What about using two non return valves intended to stop outside hose contaminating household water ? www.screwfix.com/p/pegler-single-check-valve-15mm/14639 Paul H

	Non return valves wouldn't do it, backflow isn't an issue and they don't provide the switch between circuits. I've got a central heating valve and I'll see how that goes. You're one of the Minor guys from the 'other' site aren't you? I'm currently making a heater out of a Golf matrix and bits of aluminium rivetted together. Should be more effective than the old Minor/Mini one and will fit up in the bulbous bit behind the speedo freeing up the space where the old heater went. I need to update my 'Readers Rides' on here
