What do we think, problem?
My recent engine purchase looks fine from the surface but on pulling the coils out I find this. I've not had chance to comp test it yet but
what's the prognosis do we think?
Engine supplied as working fine and with guarantee but I'll never get to claim it due to being a long way off running. Just wondering whether to
raise it I guess!

that doesn't look too good, could be simple water ingress into the cavity take the plus out and look at it and compare with the others. Got to
say though they are a cracking engine with a turbo. just sold my 1.8 20 valve turbo 200bhp after a remap. The coilpacks are reknown for their failure
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

Could just be a loose plug, but get it out and shine a torch into all the bores to have a looksie.

Plugs out tomorrow I think. I'm hoping it's just an old injury from a blowing plug but all alloy engine with uneven firing/gas leakage is
always worrying. Problem is I've no starter at the moment to crank it over either 
Considered turboing it but I think I'll just get it running N/A for now, think I'll have more than I can handle anyway!
I've got 7 other cyls, can't I manage without one? 
Should have bought that borescope that was in aldi a month or so back!

Could be just a loose plug, (check the plug and head threads when plug removed).
OR , it could be that the seal(s) between the metal plug thread body and the ceramic body have failed. It does happen occasionally, I (the garage of
which I was the manager) fitted a new set of plugs on a Peugeot once, it ran fine until it warmed up thoroughly on the customers 20mile journey home,
at which point it promptly blew off one of the plug leads and gave the engine a misfire. Initially I blamed the fitter not tightening the plug of
fitting the plug lead properly. When It did it a few hours later (again) I took a new set of plugs and fitted them, never heard from the customer
again, until the next service.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

I hope you're right. Completely unknown history on the engine means it could have been an issue that got fixed, or it could still be an issue,
might have been the reason the car was binned etc. Full diagnostics will have me sleeping better! Cheers. I've never seen a plug blow through
but I could believe it quite easily, thanks for letting me know of the possibility.

Plugs, 1-8. No real indication of the problem item but looks like they've never been changed.

Curious green deposits on some. Nasty looking oil on others but possibly 80K's worth of oil deposits just never removed. Valves look shiny clean
and nice.

Could just be the coil overheating then.
