Have you tried swapping the hoses round? I've read on here that the one off the back of the head should go to the lower pipe, I'm just about to connect mine up and not too sure which way they go!

[e36bmw12]

Yeah that's how they r connected I think there's air trapped in matrex so I need to keep trying to bleed it till It all cums out grrrrrr but thanks any how

[brucey]

Ah ok well that's helps me out then cheers! You tried jacking the front up while your bleeding the air out? That's sposed to help too I think.

[e36bmw12]

Yeah I've rye every thing r u doing a conversion ?

[brucey]

Yea, very slowly doing an m50 in mine. You got yours on the road yet?

[e36bmw12]

Yeah I've had mine on the road since march this year u got much let to do on urs ?

[brucey]

Nice. Fair bit to do yet. Worst bit will be the exhaust tho I reckon. What did you do?

[e36bmw12]

Exhaust ant bad I've used BMW stainless six branch an e30 325i centerbox and an e30 325i stainless back box and that's on a m52 2.8i and she runs mint so if ur doing an m50 2.5 that sort of set up would be fine mate

[brucey]

Sounds good mate, is that standard 328 manifolds modified to clear the steering column? I reckon i'll be doing something like that on mine.
Did you get your Mot alright then? no hassle?

[e36bmw12]

Yeah I got my mot done fine they didn't Evan notice till I told them but I only told him coz I new him tho wot was urs b4 u started conversion ?

[brucey]

Lol thats alright then! Mines a 318i so they might notice! I've got all 325 suspension and brakes to go on it though so hopefully it will be fine. What did you start with?

[e36bmw12]

318is

[brucey]

Good base then. You tried the heater valve? I'm out of ideas after that, i have heard that they can be a pain to bleed properly! Hopefully worth it tho!

Yeh they are a pain to bleed, when I replaced my radiator I jacked it up at the front and it took no time at all.
