Afternoon chaps
After posting various bits and bobs on various threads, thought this deserved it's own thread. Long story short when the head came off as HG had let go (cyls 2 and 4), there was a horror story in cylinder 3, bad scoring on about 1/3 of the bore. There is also light scoring in bore 2, this was evident at last HG change 60k miles ago, but this had not got worse. So as I write this the short motor is with AMAC engineering for a full rebuild, and they also have the head for skimming.
We are getting Westwood iron liners fitted, and are using a set of Wossner forged pistons, type that are coated for iron liners and not alusil (K9531DA pistons). AMAC have done a few of these and know their onions. For what it's worth the horror Wossner stories banding about are with alusil bores and the alusil compatible coated pistons they do. Iron liners would be much less susceptible to damage anyway but fairly happy after all my discussions and research that this is the way to go and have full trust in AMAC.
So in addition to that, AMAC will check, polish and balance the crank, fabricate a pick up pipe strengthener, new mains and big ends, all gaskets and seals done. Basically a complete strip down and rebuild of short motor with all parts cleaned, inspected and replaced if need be. They will also source the correct thickness of Cometic gasket once the work is done.
Once that is all done we will get the valves reground with new stem seals and the head cleaned up before re-assembly. I will fit a new water pump, thermostat, plugs etc as a matter of course. The other issue is that some wiring and sensors that have been brittle have given up the ghost when the engine came out. So we will slowly attend to all these matters when putting it all back together.
It's been a fairly long journey so far, as my mate who is removing/reinstalling engine is just doing bits and bobs when he can. AMAC tell me one month for them to be done, expect that to at least double!! Then probably looking at further month for reassembly back up here. I'd imagine very tail end of the year before she turns a wheel again and I will get the bonus of running her in with snow and ice everywhere!!
Anyway, could have been doing without this but needs must and I should have a nice strong, fresh engine to show for my efforts. Cost is currently looking about £5k - £6k in total barring any further issues.
Currently debating the clutch. Was replaced 60k miles ago and I've not given it a hard time. Would like to avoid buying a new one as bank balance already on it's knees!! Just a thought, could the friction plate alone be done if need be? Haven't looked into this at all yet? I've asked my mate for a condition report...........
I will update when anything develops.
Cheers
