Thanks for the reply strange design that the gasket was integral, did the think no one would ever be opening the engine
They must've been good for a few openings but time + heat won't do them any good! I doubt Peugeot, or any other manufacturer for that matter, envisaged any part lasting 20+ years.
The block has been measured and it looks good. Should've spent the time to record the results but I think the biggest variance we saw over the 4 bores was .03mm which is just over 1 thou in old money.
It was suggested to me that my low compression figures could be sticking/stuck piston rings so I was given a can of 'kill or cure' to see if the compression figures could be improved. Supposedly this is only available via a garage and shouldn't be used DIY however, it can be found on ebay and Amazon.
I was warned to only run the engine for 20mins as the additive thins the oil and significantly reduces lubrication.
Well, it definitely does something as the hydraulic lifters became very noisy and the dirty oil and debris that came out surprised me.
This is the oil before additive.
And here's a sample of what came out
Sadly, compression results were pretty much bang on what they were before.
I think the reason this engine is down on compression might be due to the 'chip' that was replaced on the ECU. I suspect it was just causing the management to overfuel resulting in bore wash. When I first got the car it had felt a bit mediocre but getting the timing correct had improved things a bit. The compression must've been down from before I got it but I doubt the seller had any idea.
When I put the engine back in recently, after a 5 month lay-up I did turn the engine over, with the spark/fuel relay removed, to get some oil circulating but perhaps things were a bit 'dry' still and that's polished things off?
Anyway, parts have been gathered and the rebuild will commence shortly.
I won't know what headgasket I'll need until the head's off and I've measured it. It has been off previously as the valve stem oil seals were replaced back in 2012. Hopefully there's still some material to play with.
