Alas, it's worse than that. I had no problem at all removing the guide pins - I missed a timing chain cover bolt when lifting the head.Removing upper timing chain guide rail pin - 1993 190E M102 engine | Engine
the problem was you didn't remove the timing -chain guide rail pin/s which effectively attach the front of the head to the block before lifting the head causing the head casting to fracture- best now with a replacement head the 2 litre won't fit the 2.3
I reckon that whatever bonding agent is used, the moment that chain guide pin is refitted it will split that crack right open again :-(Quick update - left the head with an engineers outfit today. At least I caught it in good time - there is absolute minimum warping.
So whatever the guy takes off the head he'll also take off the broken piece.
His opinion is that he wouldn't weld it as it's such a thin wall at the front cover; but, given that it is a cover, not under pressure and not subject to shear stress, he's fairly confident a high temp bonding agent will see me right, so long as I fettle it all in.
Sourcing a used head was looking like a very expensive option - not impossible but not much choice in Ireland (and shipping has become a real nuisance and very expensive)
I hear ya, I really do! I've made a few calls and I'm watching ebay and the small ads. But no luck - as yet - with an alternative head; and shipping prices and logistics across the Irish Sea are nuts at the moment. I might check with a pal in Belfast, could maybe get one shipped there. When the 124s were still being run as taxis, the breakers around Dublin were full of them. But they tell me they crushed a lot of older cars when metal prices were high. It's almost as cheap to pick up the whole engine now as just the head.I reckon that whatever bonding agent is used, the moment that chain guide pin is refitted it will split that crack right open again :-(
You can pick up a used head for a little over £100, and that’s where my money would be
These heads never seem to warp, the stretch bolts towards the rear of the head tend to work loose and/or they suffer corrosion when left in poor condition (ie leaking) for extended periods of time.
I think if you pay to get it skimmed and new gaskets/bolts etc you’ll be kicking yourself if it doesn’t work out?
That would be ideal - listing says doesn't ship to Ireland, but I'll contact the seller right now. Thanks for the tip, much appreciated.Mercedes W201 190 W123 M102 230E CE TE cylinder head 2.3L R1020163201. Head is freshly planned and incomplete as in pictures.www.ebay.co.uk
Is shipping from Germany to Ireland easy enough if it’s within the EU?
