hose routing questions - 2.5 petrol

I am not sure how far this deviates from stock, but I don't think it's a stock configuration (Kent's 110). We have two questions

1. How to properly hook up the coolant lines to route through the intake manifold
2. where to hook up the breather line

#1 In this picture, the red circles show the ports in question. I assume the barbs on the intake manifold are to run coolant through the manifold to warm the intake air when cold. After hooking up the heater hoses we have one port on the right rear of the block left, but no return point. Where should we tee this in to? Stephen from SafariHP sent a picture of a LHD 2.5 setup and it looked like the line coming front he intake went to the right of the radiator but you couldn't tell where (and we have no free ports on the radiator). We also can't see the right rear of the engine in his pic.

#2 I circled a place on the carb in green that might be where the breather line should go, but it looks like it's blocked off. The breather line should go to the carb right?

tia,
charles

Here is another picture showing the manifold ports.

The green is the one I was wondering if the breather line should go to, but looks plugged

There are some photos here: http://www.defendersource.com/forum/...ad.php?t=36670

It looks like the breather should go to a T and then the air intake, which is missing in the photos you've posted. I doubt it HAS to be that way.

For the carb heat, you run one of the heater lines through the carb.

You will have to run the crankcase vent to a bottle since you don't have any intake plumbing. What you have is an ACR SU carb kit there.

Jafir that helps thanks, but it still doesn't show the right rear port on the engine, nor where the line goes coming from the carb (assuming the rear engine port goes to the rear of the engine).

John, the way the heater lines are run doesn't really account for this. If we put in a T, what is the sequence?

back of engine -> carb -> T in heater hose?

Yes it's an ACR engine too. I am not a fan of just using the K&N - would prefer a proper air filter setup, but good to know the crankcase vent solution is to route it to a bottle, thanks.

Only 1 heater line needs to be rerouted. The return line from the heater is routed through the SU, as per ACR. The water outlet on the rear of the head, can be blanked off, or a tap in closed position, as they use that for earlier series motor set ups.if the carb is blanked out, the breather can be left open. If not blanked, then you can connect the breather to the carb. Here is a link to the ACR page for the SU carb set up. http://www.automotivecomp.com/pdf/PP...CARB%20(1).pdf

You run the return line through the carb with some heater hose. The existing line is not used.

Oh Greg, should we have the two throttle return springs somewhere?

Since the motor was based off a late series 3, the rear water port was open. It can be plugged off for the 110. Yes there should have been the 2 springs, with some other small parts from ACR. There might be a chance they were placed in a small box, from the Petronics unit, but I think it was in a plastic bag together with other parts.
