So...I used ARP head studs at 65 pound, OEM gasket, Benson sleeved block with O-ring.

I had to refill my over-flow bottle... its like if my rad is drinking it ?? But last week I changed my water pump and refilled the car... maybe it was air in the system... but if I remember I had to refill it more than once...

Under boost my car is like misfiring...could it be some water who is passing throught my headgasket to the combustion chamber ?? But for this point im not too sure if its not a spark plugs problem or a tuning issue...

When I was not sleeved last summer... I had a blown HG and the water was exiting by the overflow bottle...

Anyway tell me what you guys think about that... and ELspool dont laught !!!

 

lol, did you blead the system of air once you changed your pump and added more coolant?

 

lol you are always here !!!

yes I did it really fast but its a possibility... before this I had to refill the overflow like 2-3 times but my water pump was leaking a lot... Its just because it happen at the same time that my engine do some misfire at higher rpm under boost ....this makes me nevous loll

 

you may have a pin hole in a water hose somewhere that once the system warms up it leaks out and as it cools it draws the water back in..most turbo cars with a bad head gasket will fill the reserve..not drink it..I would check for a leak.

 

did you wait til the thermostat had opened to top off the system???

boosted_dc2 I think you got the right awnser ! I completely forgot to let the thermostat open...and refill... its probably this !!!

My misfiring problem is probably another problem loll
