ok so i have a b18b, i just turbo charged the car. everything was fine till today. there is no pressure on the top radiator hose. car is idleling funny. what can it be?

 

could be the waterpump... that would cause a funny idle if it has seized if it were the headgasket i think the upper hose would be rock solid. do a compression test and see what happens. does it overeat at all?

 

no the temp is fine. no overheating just funny idle it moves up and down from like 1000 to 7000.

 

thats a pretty big jump... i doubt a headgasket or waterpump would cause that...that sounds electrical

 

electrical like what?
how about no pressure on the radiator hose?

 

thats not electrical... over time hoses get old and get soft.. that could be what it is... it could be a headgasket, water pump, thermostat.. but none of those would cause the idle fluctuations

 

i took my car once to this guy and he squesed the hose and i think he said the headgasket was bad not sure thats why i asked. well if i do replaced it wich one will be good for turbo. i have low comp pistons 9:1 and a blockgard. im boosting 9psi.

 

squeezing a rad. hose is no way to tell if a hg is good or not... just get an oem gasket.. best you can buy.

 

ok, in the morning ill do a comp test. ill change the water pump, thermoS, headgasket. just in case. last time i changed them was 3 years ago.
thanks wantboost

 

no problem... post back if nothing changes

 

cool i will.
