hi people, im currently removing the cylinder heads from my 3200.

i have seen this at the back of the engine bay, now to me this t-piece doesnt look standard? looks bodged ? or the hoses are wrong?

what should be here and whats it called and who can supply it one.

also.

i have loosened the manifold from the head (what a bloody pain in the **** that is in situ!) but i cant quite get it off enough to clear the studs to get the head off (so close though!) is there some sort of bracket holding the turbo/exhaust to the engine block? where abouts if so? or anything else stopping me getting it off, the oil and water hoses dont seem to be holding it a great deal and the boost hoses are a pain in the **** to get to atm too, but none seem to be preventing the manifold to move though.

many thanks, beau.

Looks like an aeroquip part to me. You might even find it is threaded under the jubilee clips? I have used them in the past, and they are quite good, but they normally come with screw on hose take offs so if I am not wrong, it is a bit bodged to a purists eye!

The T piece is wrong, you can see that the coolant pipes that connect to it are being crushed by the jubilee clips.

As for the head removal, I think you might have to raise the engine, with both manifolds removed, support with trolley jack and undo the engine mounts and you should be able to manipulate the block to gain the clearance you need.

Change that T piece and the pipes and also locktight the plenum belly plate whilst you have it off, they are notorious for coming undone.

hi, yeah thought it did look wrong, cant believe someone would put that t-piece on thats way too small, il try find another, i just wanted to confirm it should be a seperate t-piece or was it a 3 way hose originally

the heads i just need them to clear the exhaust manifolds, need the move the manifold off the heads another 10mm to clear the studs to lift the head.

what is the plenum belly plate?

thanks! :)

Beau, the plenum is the big intake the mounts onto the heads that feeds the engine with its fuel/air mixture, it has the throttle body mounted on the front of it.

Flip it over and you will see a plate on the bottom. Remove the plate, check the condition of the gasket and then locktight all the screws back in.

If there are any of the screws missing, look in the 'V' of the block, they fall out and reside in there.

Try your local dealer too, they might have one. There reason I say this, is if its not in stock at Eurospares, I have found they tend not to bother too much.

Hi together

in my opinion the T-Part is the correct one - the hoses are just blown up. Unfortunately I did not focus on the T-Part but you can see it`s a tiny red one and the 2 connecting parts of the water manifold to the engine block or the straight coming top-left out of the manifold to the heater show how they look when the time is nearly over, they increase their diameter quite heavyly. If their original diameter would be that fat compared to the T-part you would not be able to get this tightened. Diameter must by +-1mm to get this tightned

The hoses from the manifold to the unions between the head inlets are also grossly inflated. You need to find out why, and change them. They don't look like the correct re-enforced hose.

Hi Arnie

if you are refering to my pictures - these where taken before the exchange to silicon hoses as one of them was already opened slightly-I forget to make a picture when re-assembled with silicone hoses - I reported about that in another thread. But I crosschecked now -they are reinforced, but maybe some cheap replacement or its just their age 13years/93000km

I reckon all the hoses and clips in your photos have been messed about with; the jubilee clips look Halford specials and the wrong size. It wouldn't surprise me if someone has revamped the cooling system with new hoses and clips from an accessory shop.

the problem is that some of them (e.g. the 3 on the T-connector) are curved hoses, so one would need to give a sample to ..lets say "Paul" so that he can do them. For some of the hoses I have posted already some of the sizes so one can order standard ones (straights or reducer an tailor them). For the small zig zag I have an Maserati original and I wanted to send it to Paul so that he can make a silicon one and add this to the Maserati 3200 hose kit- but I was quite busy at work, so I forgot to do this. Unfortunately this seems to be common that we get the 3200 GT Kit only complete when additional missing hoses are sent as also others are waiting.

Is far as I remember the mounted hose clips where from "Norma" the car was/is living in Italy/Germany so neither Jubilee nor Halfords are typical brands used here. But I agree some hoses (not in the picture) didn`t look like water hoses. E.g. there was a small straight for high pressure hydraulic application fitted.

Jubilee is a generic name for screw type fasteners which aren't generally used by manufacturers. I guarantee that the majority of fasteners in those photos are not factory fitted. No manufacturer would leave so much strap hanging out beyond the screw because, for starters, those jubilee clips are the wrong size.
