Diesel - Head Gasket? Water Pump?
Discussion
Evening all, sorry I know this should really go in the Vauxhall section, but after a speedy response.
I've acquired a 1.7 Diesel Astra Van, It's T-Reg and I've paid pretty much scrap value for it, it's running and has an MOT, but its been sold as needing a water pump, the guy who bought it thinks it needs a head gasket and has therefore sold it to me, Cheap!
So, before I go ripping the head gasket off, these are the symptom's:
Engine runs, perfectly, all four cylinders, no smoke on idle, although a little oily smoke on a short drive (has been stood for a few weeks).
If I take the cap off the coolant it has a very slight oily residue, but also a pressure as if something is pressurising the whole system.
Your thoughts?

For the amount of effort, it's really just worth whipping the head off, clean it all up, new gaskets and bolts, job done. Take about a day. DON'T get the head skimmed unless there's significant damage.
Then you have piece of mind.
Almost all head gaskets will fail eventually. They rot from inside out (if coolant is not renewed regularly), they rot from outside in just due to age. you could also slip a new belt on and then forget about it all for the next 4-5 years and just drive it.
thats pretty much the plan, I'll give the whole thing a good clean while it's apart!Then you have piece of mind.

1.7 Diesel Astra, it's the oil cooler
it breaks down internally and lets oil into the coolant system. Fairly easy job to do, but don't forget to budget for new fluids. Oil coolers run about £100 from a dealership. HTH
I also suspected this, but there is very little oil in the coolant and it's pressurising with gas?!it breaks down internally and lets oil into the coolant system. Fairly easy job to do, but don't forget to budget for new fluids. Oil coolers run about £100 from a dealership. HTH
I found coolers on ebay for £30 but with the gasses pressurising the coolant surely it's the head gasket?!??

What's the car worth if no issues?
What is the cost to get it fixed?
It may be uneconomical to fix.
Worth thinking about as these are ten a penny vehicles just my 2p
no issues, £5-600What is the cost to get it fixed?

I've paid £300
Head gasket will cost £40, oil £25, Coolant £10
so £375 for a fully functional, serviceable astra van, I'd say it's economical to fix?!
