Evening all.  Some advice needed.

We recently purchased a w reg 2.5 elite saloon for the princely sum of £200.
It has since developed what I thought was a misfire, but it has been diagnosed as water getting into one of the pistons.

Local garages are pricing head gasket replacement as a no go(£600+).

Is there anyone on here who is capable of doing the job at a more modest price, or does someone have a good replacement engine that I could drop in.

I dont want to scrap her as she normally drives lovely, but as money is nearly non existant, that is looking like the only option.

Any help or advice would be greatly appreciated.  Mark.

How've they diagnosed the head gasket having failed? I.e. have they done a leak down or block tester?

How have they found water in the pistons? Or have they found water in the plug wells?

How was this diagnosis done? What are the symptoms? Is it oil in the expansion tank?

The V6 head gaskets rarely fail, the 2.5 is one of the strongest of the bunch.

A mechanic diagnosed water in the pistons. Said he could hear it as soon as he lifted the bonnet. Told us to put rad weld + in which cured it for about 10 days but the misfire  under acceleration is back. As the wife says it running 'rough as rats'.

Talking utter shite
Worst thing you can do

Basics,are you losing water,yes or no.
Is oil milky on dipstick,yes or no.

OooooK 

I'd personally never use any mechanic again, if they advised rad weld. It's such a bodge, it often does so much more damage to the cooling system.

A missfire under load could be a number of things, head gasket would be at the very, very bottom of the list. (of about 1,000 other possibilities  )

1) Are you loosing coolant?
2) Have you taken the spark plugs out? (inspect for oil/water)
3) Is there oil in the coolant?
4) Do a "paper clip" test, details in the maintenance section
5) Post up these codes

It using about a pint of water a week. There is no oil in the water bottle and no mayo in the oil filler neck.

Cant paperclip as no eml bulb, but no codes if I plug in a reader.

[RobseyMV6]

Steam coming out tail pipe all the time?

If it`s an OBDII diagnostic you`ll get naff all codes

[MadMark73]

No more steam than I would expect in relation to other cars in the mornings.

There is oil in the plug wells.

[RobseyMV6]

I sent you a pm could this be hbv?

[tunnie]

Taken the plugs out for inspection? Most common cause of miss-fire on 2.5/3.0 is a faulty dis-pack or HT lead.

Sorry but I don't believe no codes, not on an Omega 

Take the dash out, put a bulb in and read the codes

As RobG says, 3.0 are NOT OBDII compliant
