have noticed tonight that there is a slight oily film sitting on top of the water in my header tank

at first i thought head gasket but checked dip stick and filler cap and no cream

also when giving it larry large the temp shoots straight up,but have noticed that there is coolant all being sprayed out from the cap?is my cap fooked its a pace alloy header tank with a standard yellow ford pressure cap/

help

 

Cracked block ?

Thats what mine was

I hope not.

Steve.

 

me 2

 

mine sprays out from the cap on the header tank but only on trackdays.

Me mates monte started doing that a few days before the engine blew up in spectacular fashon

 

mine use to do it before ihad it rebuilt it was the head gaskit all because
my fans wasent working

 

I'm sorry, but don't sound good.

 

Well, You do push it mate! i mean racing evos and anything in sight got to take its toll some where!

 

shit mine got sludgey stuff in the header tank as well!

 

Thats not good

 

best thing to do is go and get a leakdown test done on the cylinders, this will tell you if your head gasket is suspect....or you have a crack in the combustion chambre (head not block) it will show up as a leak...funnily enuf

if all is well with the leakdown then im afraid you have bigger problems....ie crack in ya block...

 

It may just be the head gasket.

 

Most likely head gasket, seen this on several cars.

 

Yeah, but we shouldn't stop the doom mongers fun

 

Doomed Doomed i tell ya lol

 

do comp test that will tell you but its gasket or block hope 4 the gasket

 

what sort of place can do this?

can i go to any old garage or does it have to be a speciallist tuners?

 

mines doing this at the moment too lol

no sludge on dipstick etc, engine temps fine, no smokey zorst either

the cars running fine other than this oily film

matt

 

what you mean it isnt a driveway ornament? my god theres another person on this forum who drives their car like they should

 

9awaits backlash from ornament drivers hahahahhahahah

 

it can idle all day long and the temp wont go above halfway,there's no smoke from the exhaust,ans as said no sludge on dipstick or filler cap,just as soon as i give it 30psi it just shoots straight up but the only reason i can see this is because half of the coolant is being sprayed over the engine bay


booked in for a a test on sunday
fingers crossed

bloody car got a list of new parts to go on it as well,for even more power

 

you need a micanic friend if poss

 

I mean if you seen this guys car go you know what i mean, bloody thing scared the shit out of me!!

 

head gasket fooked cylinder to water jacket... not enuf of a bang on idle to cause any pressurising of the water system, however on 30psi i would imagen its pushing past the break like mad.... good luck....and a comp test might not show it up if your car is ok on idle, what you really need is a 150psi air line and do a LEAKDOWN test..... this will tell you much more,,,

 

i drove for a week after spotting this then the head gasket went with the block and at the time my oil cap was normal.

 

Driving it "like it should" has probable fooked it!!!!

Revs kill engines fact

on turbocharged cars revs and or too much boost kill engines fact

so lay off the rev limiters and watch ya boost pressures

At the ring last week I set myself a rev limit of 5k still got round in similar times to more powerfull cars

still broke the car tho so what do I know!!!!!

 

for some cars id agree, others id say it depends whats been done..... you know how the cossie gets driven, and how much boost it runs.....

im yet to blow it up after 2.5 yrs

 

My car did this and it was the begining of the head gasket going. new gasket and all was fine

I hope this helps

Cheers

mines the same no sludge on dipstick or oil cap, doesn't smoke or effect its drive. temps are fine as well

just uses coolant up & has a oil film on top, (and is discoloured, like oil is in the header tank)

does that just sound like head gasket or something more serious?

also whats sort of garage can i get a comp test done at?

 

that happens when the head bolts/studs cant keep the head on the block ,and thay sepererate, allowing the head gasket to leak on boost.

is it long studded? if so i would check who made the studs.
