strange sound from engine.....

[LegoHead]

sounds like air being sucked into the coolant somewhere, plus a little white stuff under the oil filler cap. Is this normal after an engine rebuild.

Plus I can definitely smell coolant out of the exhaust. :dapprove:

Just want some reassurance it's not the obvious.

And can you guys give me some info on how you would test the HG, apart from compression testing.

doesn't sound good mate!

you need a "sniff tester" to test if there is gases in the coolant

can i get one from halfords?

 

[Fred@BTM]

na i doubt it, its a specialist tool

its a special tube thing that you put this chemical in that changes colour if it detects gas

 

[Jay Payne]

If u manage to borrow one of those tools Fred is on about, make sure the fluid is ok. It has a use by date on it

As previously said you need a sniff tester or otherwise known as a block tester. These will be available from most motor factors, or you could take it to a garage and ask for a block test, should cost no more than £10-£15 (at the most).

call the aa, they carry them dont they?

 

[clionoob]

if youve got a milky substance on your oil cap then looks like your head gasket is going or gone!

Well it's not looking too good, but all should be sorted. I am hoping it is something simple like a split hose, turbo leaking or the charge cooler leaking.

If not the garage have it now. Thanks for all the info.

Shame that is having a turbo would be great but the maintanence is ridiculous!

 

[LegoHead]

Was a false alarm, but always makes you wonder when you hear new noises. Just turned out to be the crappy silicone hose splitting at the turbo.
