small amount of water being pushed out of overflow :(

[dac69er]

been mapping my car at 1.1bar. when i got home i noticed that the coolant bottle had pushed out a little bit of coolant from the overflow, i did check the levels quite often tonight and never noticed the coolant level was any higher or lower than it normally is.

when i say a small amount im talking round about a teaspoon full

is this definitely a sign of headgasket or could it be something else? i have a alloy civic rad with a new cap, but it was cheapish so could it be the cap?

engine was completely rebuilt using toyota parts, thermostat is new, coolant temps are fine etc. whats the verdict?

I'd stick another rad cap on it first before jumping to any conclusions.

baring in mind i was doing flat out runs in 3rd and 4th and a bit in 5th to get some good data to work with. did it a few times in a row!!!!!

i shall order a new rad cap tonight and stick it on next week when it turns up!

Even though a cheapo im assuming the rad cap is 1.1 yeah?

 

[dac69er]

Correct, its a 1.1. It came with the rad and it seemed ok, but the rad and cap was only £80 delivered so it may not be great :s

Thats about the average price people pay nowadays for them and are faultless, tho thats not to say there isnt bad ones.

Pulled the cap off this morning as its all cooled down. Seems all ok, there was some paint round the sealing face from the rad so I have cleaned that up in case it was causing a sealing problem! Will keep an eye on it and see how it goes I very rarely do back to back runs flat out often so It probably won't do it again!

just ordered a 1.1 bar hks cap as i had some spare cash in my paypal. will see how it goes with that when it arrives!
