We all love to diagnose running problems and often I read of new and unheard of problems but many of us have got it wrong by trying to understand symptoms via the screen where we don’t see all the info that’s really needed to analyze so don’t be too dejected until you have had it checked out professionally.
The good thing with modern cars and their computers is that you can attach a scanner and read the error codes, this may or may not show up your problem but I believe it’s your first port of call.
If you don’t know anyone you can trust then give Jason at Full Flow Injector Cleaning a call on 0419 500 707
He handles diagnostics as well as injector cleaning and often sorts out problems for workshops that can’t work it out for themselves.
I think your down eastern Suburbs? Jason mostly works the Western & Northern suburbs but I’m not sure how wide his run is so you should give him a call, he’s a straight up guy (rides dirt bikes). Tell him I sent you, no maybe don’t mention me in case you turn out to be a pain in the arse job.
Just had a win myself, thought the wifes VE had done a head gasket, had me stumped for ages how it kept losing water all the time, been getting worse of late, whenever I checked the water the system always had pressure in it and it had the tell tale bubbles coming up through the water so I had convinced myself that the head gasket was done even though it never over heated unless I forgot to check it and it was down on water.
That was until I noticed bubbles coming up through the water even though the engine wasn’t running, then I finally twigged that the gas convertor must have corroded and was leaking gas into the coolant system.
Couldn’t work out why some days it would be fine but most days not, in hindsight it was always fine when the wife had run it out of gas and flipped over to petrol.
Just running it on petrol now until I can get it fixed but it should be a cheap fix compared to doing a head gasket.
