How to change an astra van oil pump?

things to check before...low oil level,blocked filter,broke hydraulic tappet...

if i recall the oil pump is fitted round the front crankshaft pulley...off with the sump and your there...also check that the pump pickup isn't blocked.they have a Mesh over it that can soon be blocked.How to change an astra van oil pump?
First thing hook up a manual oil pressure gauge to see what your oil pressure is. You might have just a sticky lifter. You can buy some liquid at a good automotive parts store for noisy lifters, sometimes it works, and sometimes it doesn't. Check the pressure first its a big messy job.$$$$ if you get them to fix it.How to change an astra van oil pump?
HI

Yes don't just jump on the change the oil pump wagon... it might just be low on oil. could be a stuck lifter, it could even be an exhaust manifold gasket leak too as they make a sound like a ticking lifter.

Get a second opinion. to change the oil pump they would all most have to pull the motor out, Or at least drop the oil pan.

good luck

i agree with the guy above me but you should make Absolutely sure that it is indeed the oil pump that is not working. It Could also be that there is a leak/crack in one of your heads and oil is being forced down the valve covers into the pistons and you may just be burning up your oil. remove your spark plugs and make sure they don't have any oil on the ends.How to change an astra van oil pump?
a ticking noise from top end, means an oil pump problem? That different! Don`t even think of changing the oil pump, try draining the oil, running some Wynns or similar, through it first. this will remove any carbon deposits and sludge, then give it a good blast down motorway, should sort it!How to change an astra van oil pump?
I'd start by changing the oil %26amp; filter %26amp; refilling with a good quality oil. Don't assume the oil pump's at fault, I think that's unlikely.
