expecting the worst!!

[TonyN]

all other pots are in pristine unmarked condition (well except for black carbon marks) but this pot is well and truely gone. heavily pitted and the wee swirl chamber cover is cracked. the other 3 chamber covers are also cracked. is that normal?
the top of the piston for corresponding pot is also lighty pitted but not as bad as cyl head.

i think water must have been leaking into this pot for a while - judging by the cavitation pitting.

Yeah, that's been running while cracked for ages to be as bad as that.

Small cracks in the swirl pots are fine and normal, but you'll get new ones in new head anyway.

[s car go]

That crack between the combustion chamber and the valve is almost identical to how mine cracked,but I did'nt have the pitting!!

Good luck with putting it all back together,I'm sure you'll be fine ,but if you need anything,just shout!!!

Regards

Well at long last I got my head off - about 8 hours work over 3 nights in total - taking my time and putting bolts in individual labelled palstic bags.

quite suprised at what i found. this is picture of top of pot 2nd away from bulk head ( pot 3?). all other pots are in pristine unmarked condition (well except for black carbon marks) but this pot is well and truely gone. heavily pitted and the wee swirl chamber cover is cracked. the other 3 chamber covers are also cracked. is that normal?
the top of the piston for corresponding pot is also lighty pitted but not as bad as cyl head.

intresting to note the lack of gum/gunk/soot on head and pistons - as i have ran this engine on SVW / WVO / home made bio for last 100,000km.

The purple/pink spots around valves on picture are from a dye pen' test to check for other cracks - non found.

Well just ordered new head with fitting kit and other odds and sods - total £900. - hopefully arriving tues morning.

wish me luck on refitting!!

I used to work in a Ford garage we partially drained the oil then used paraffin to flush. Cheaper than engine flush and does less harm.

Are you suggesting others do this?


Anyone reading, please ignore this utter nonsense, it will most likely #### your engine up.

I pity the poor #######s who visited your garage.

stevo and his team did mine ,same day fitting service runs like dream now,had it done last october 2010 levels the same now as the day it was done.

I've flushed this with ATF (1/2 pint to old oil run for 30 min) with no ill effects twice in four years, OP says he has contamination/mayo, personally I'd want any cross contamination out of both oil and water, he could put through a 5lt of cheapo oil n run that for a few miles as an alternative to get the crud out.

Ditto.
Engine flush should be left on the shelf next to the snake oil.

Probably get me more abuse, however, oil/engine flush is a bad idea IMHO.

Many cases of engines failing within days/weeks of engine flush. I don't trust the chemical clean contents of the flush in an engine.

Any of those heads will do (Steve or RT) there's also others who supply AMC heads for these trucks, nearest is in Catterick, built or not, cheaper too.

Its easy to do the job if you have the gear, (decent socket set, open enders 10mm 12mm 14mm etc and torque wrench) get the complete gasket set/belts from RT and take your time, also try not to lose the half moon bit from the cam cover and the other one from the cam (woodruff key) While its apart service the viscous fan too with new silicone oil as this part looks like its working properly but is easy to mistake its effectiveness, which contributes to the oheat problems, new thermostat, rad cap and a good flush of oil and coolants when you restart n it'll be like new.

and I had you down as a man of taste when it came to ale.

Even I think that Kingfisher or Cobra is acceptable with a curry (Although Stella is still well out of order !)
