Hi I need to seek information about my dual fuel astra van.
Emulsification sludge at the oil filler leads me to suspect the haed gasket is leaking (no loss of water, power or overheating.). The engine runs annoyingly cool or is it a poor heater? Returns 28mpg on LPG (aprox 7.5p/mile).
I have been advised to have the head hot tanked and sealed and wondered if there are any reccomended locally to me. Also advised to use a stainless steel head gasket (never heard of one before).
I would welcome also any advice, are there any complications with the Vauxhall LPG dual fuel system (not covered in the Haynes manual).
What parts must I get (part numbers and contacts).
What special tools do I need & where can I get them (water pump adaptor, cam sprocket).
Its overdue 40k service at 45k (oil & filters done) but putting off timing belt until I do the head which is pressing and nagging me.
Please help an Astra owner in need.
