Yeah-great work and technical expertise 

Can you do mine?

I dont know if anyone else has noticed this, but it seems that there is not shortage of really nice roadworthy Omegas, quite a lot of them facelifts, that get stripped for parts. Everyone always says 'worth more as parts, mate' fair point.

There are still a lot of good cars out there so even cars with relatively minor faults are still worth more in parts. The same thing happened with Monzas, Senators and Carltons but they appear to be coming out the other side now. It's surprising how fast Omega numbers are dropping when you look at Autotrader though.

But absolutely fantastic to see someone tackle a project that most of us would have run away crying from!

Ten out of ten!

Thanks, but not as difficult as you might think once you have the momentum going with the project.

[Slurpy]

Very impressive indeed.

A project where I would certainly run away from. [smiley=laugh.gif]

Well I finally bit the bullet and replaced the cylinder head and gasket this week and it seems to have cured it. I still don't know whether it's a crack in the head or gasket failure though. I will get the old head pressure tested at some point just out of curiosity.

I suspect the head had been off before though as it all came apart very easily with the gasket staying completely intact. The only odd thing was that No. 2 cylinder seemed to be a whole lot cleaner than the other but I don't know whether that was me gripping it to lift it or something else. There was also evidence of water contamination around one of the bolts and the gasket area around it but it didn't seem to penetrate to any of the bores. Anyway, a few pictures.

Damage to No.4 piston from an unknown cause.



Head bolts, notice the one rusty bolt.



The head, notice the rusty bolt hole at the top second from left, also the clean valve faces of No.2 cylinder.



It now appears to be cured, no pressurised coolant and normal running temperatures (which it had before).

This was a challenge though as the engine has been modified so much that I had no timing marks to set the valve timing by. You shouldn't need to I know, but whilst trying to hold a 37Kg head at virtually arms length I broke the cam sprocket support off the top of the chain guide. That allowed the sprocket to drop and the chain to fall off the crank. Then I discovered that the timing mark for the cam sprocket is also on the bit I broke off. So it's been timed by feel, eyesight and guestimation.

The broken bit!



So after all this effort I'm going to run it for a while and see how it behaves. If it goes wrong again I will drive it down to the crusher myself!!

I even got round to adjusting the head light height and replacing the batteries in the alarm power sounder, still doesn't make any noise though!

Anyway, now this is done it gives me the chance to build the engine that I need to bolt my twin turbos to for my Monza!

A very enjoyable and interesting thread  8-)

Woo hoo, working A/C.

So what plonker designed the location of the face lift A/C dryer then? I ended up popping out the two little plastic plugs in the side of the fan housing so I could pass a socket extension bar through to get to the bracket bolts. It's like a fridge in the car now, well when I switch it on it is!

It doesn't seem to mind that the HBV is longer in place either although we will see how it does when high summer gets here.

Total respect for effort that must of been to change it all, I'm bitching cos I have to replace a tensioner on mine but you have re-designed the whole belt system lol crazy.

wish mine had the nice mod you made to it 

hope you get the head sorted soon

[PhilRich]

You have my total admiration & respect mate! Awesome!!!

It did have me scratching my head for a while and I had a problem with bolts working loose but all sorted now!

Ah, the head is now well and truly sorted, replacement head and gasket sorted it over 4000 miles a go.

You have my total admiration & respect mate! Awesome!!!

Thank you! 8-)

Just the bottom arms, discs and drop links to do now.

Have followed this with interest.......did something similar years ago with a 2.9 V6 granada to a perkins turbo-diesel. Fantastic piece of ingenuity and perseverence, buddy, my conversion took me £700 and 8 months of (part time) fettling, but was a worthwhile conversion in the end, making an expensive luxury car relatively cheap to run (45mpg) with good performance. (only 100mph max, but all day long regardless of hills, etc.)

you are to be congratulated, mate.

Well the engine went in nearly two years a go and quickly became very stable, but then I wanted to get the A/C working and that opened a whole world of problems that have taken me a while to resolve. It now owes me around £500 but that includes buying the car.

but was a worthwhile conversion in the end, making an expensive luxury car relatively cheap to run (45mpg) with good performance. (only 100mph max, but all day long regardless of hills, etc.)

This is the same. The interesting thing is that it has the same gear ratios as a 4 speed automatic 3.0L Monza GSE yet in top gear from 60mph to 100mph it accelerates far better than the Monza.

you are to be congratulated, mate.

Thank you....

Glad it's all still going well
