Type r losing water-help please
Hi all,my v5 type r has recently undergone some mods and a tek remap raising boost from 1 to 1.3 bar,now ive noticed the rubber vent pipe in the overflow bottle spraying coolant out in to bay.I thought maybe had wrong filler cap on expansion tank so replaced for a blitz one,just come back after some hard driving and tank was empty after letting all cool down and bay was wet around battery area where all bled off,am i right in thinking the worst what people are telling me that head gasket has gone,i keep topping up and am only driving steady now. What are my best options and would buying a modded head off here be wise, am i causing any other damage and can this prob lead to other probs.Not very mechanically minded so any help advice options would be brill,anyway hope one of you fine enthusiasts can help me out here.

Fill it through the turbo hose (from the header tank end). I normally use a funnel.
Remove the small hose from the top of the rad on the left hand side (connects to the header tank). It'll take a while if the system is empty.
Once the coolant comes out from the top of the rad where you removed the small hose, connect the hoses back up and then top up the header tank. Should eliminate any air locks. Start her up and get up to temp, feel the top and bottom rad hoses to see if they are both hot, make sure the rad is hot all round too.
Hope this helps...

Really do appreciate comments guys,tried filling up like reply suggested but not much water had been lost so not losing much,secondly it seems to be more only on high boost where vent pipe leaks! As re to water pump i thought it either works or it doesnt or could it be playing a part? Also felt rad when up to temp 78deg and felt more hot at top to bottom,only a wee bit tho.What part does the rad in front of the main rad play as this was still fairly cool/cold?Sorry for all questions but trying to avoid paying the £1200 for repair.Carnetix will be doing repair if def needed as trust them 100% and cant speak highly enough about them.
Am i right in saying that if it is head, then is it because of the pressure raised fromboost that is forcing coolant to vent?
Again cheers

Hqead gaskets would be my guess
Give it away if it happens on boost.
If you aren't sure when it is happening, fit a bottle (or Coke can) by the battery and put the expansion tank Cap Pipe into it. Drive off boost for a couple of days and then see if it has any fluid in it. Then go for a 5 munite blast (LOTS OF BOOST) and then check the Coke can again.
Water in it? Headgaskets would be my bet. remember that the longer you leave it like this, the bigger the chance of damaging heads or Block faces and therefore needing the heads skimmed and block decked (more expense)

if it only happens on boost i am 99% positive your gaskets are buggered.
mine was the same
over pressures the cooling system and dumps the coolant out, you could probably drive your car off boost for 6 months without any issues (like i did)

Seriously, I would make sure your rad is hot all over before you start even looking at doing the head gaskets. I did my Head gaskets a couple of months ago after consulting my mechanic, did alot of work to the engine so was worth it , anyway all went back together.... same problem ONLY ON BOOST!! Took it to a well known scooby specialist (known on here), took a look.. said head gasket had gone again, prob a fault in the build somehow. Despite being built by a mechanic. Took it to a third mechanic, told me that the rad wasnt hot enough in places and to replace that first. He was BANG on. Drive as hard as you like...no worries, probably was never head gasket in the first problem, but did get me to find that all my idlers were close to ceasing!

I had a similar problem and was really worried about the gaskets....turned out that the rad had a small hole in it which until weeks had gone by and the problem had got worse it wasnt possible to see anything leaking at all!!!!
I would really make sure that you are very sure before taking the heads off!!!!
Try a compression test on each cylinder...a leak down test on each cylinder....does the oil have a murky mayo in it? Air locks seem unlikely to me as the system seems to clear itslef real easy from my experience...make sure the heater is set to hot when filling.
Not sure what else to suggest. But know I would explore everything before taking my engine apart

if you have a hole in your radiator, you will loose the coolant from the radiator
not sure how you loose coolant from the overflow pipe when on boost, if the radiator has a hole in it ??
oil with mayo almost never happens with scooby lumps.
the pressures leak straight into the coolant system
