Hey guys, I have a Bf F6 Typhoon, 78000kms on the clock.

I have been getting a coffee coloured sludge in my coolant, but no water in my oil. I have already stripped the car down and changed the head gasket, while doing this I found water in going into my water pump and I'm not sure what is causing that....

I have tried to flush the system, but I've only used a hose, should I take it in to someone to flush it for me?

That took me a while and recently I have put the car back together and I taken it for a test drive a few days ago. Was running fine and on the way home I gave it a bit of kick to bring my turbo in and my battery light came up first then my oil light, then my engine dropped out???? It did however start up straight away when I came to a hault on the side of the road and I drove home slowly. Today I started her up again and while it was only ideling the oil gauge is sitting half way, Im not sure if this is a bad thing or if its just because of start up?

I'm not sure where I should go from here, any advice would be muchly appreciated!

Cheers

oh and after the ride the sludge was still in the coolant reservoir.

Cheers

Water going into the water pump? Please explain.

Can you pull any codes from it? The sludge could be residual oil from the head gasket change.

When I pull the water pump off you can see oil trickling down the interior. Nah I haven't pulled any codes as of yet. I'm hoping its residual but I've just checked my oil and I'm still losing oil.

oil in the water pump housing is bad. Would indicate a potential cracked block

Get the cooling system properly pressure tested and leave the guage on it for a few hours to test for pressure loss. That will at least confirm loss of pressure and therefore coolant and maybe the source ( if visible) . If the coolant is leaking but cannot be seen, you might need a compression test to see if a bore has split or you have lost the head gasket. Bore cracks can usually be seen - if really small the giveaway is a linear discolouration in the bore. It is unlikely however.

The last thing that comes to mind is a porous or warped head - rare again - but possible. That can be diagnosed by removing the head and a pressure test and a straight edge.

This needs a proper investigation and good equipment to do the diagnostics.
