That last bullet point is the key! Described exactly this to RPI and they had 'no clue' what it was, instead letting me spend a pile of money on what is now scrap

I think I would be happier having it top-hatted.
but the fire ring is to the block on a regular linered engine, thats why we have top hat liners, to seal against the fire ringIf the fire ring stays intact not sure if that would happen, That said vvv wot e sed
We were eventually.

plus, how do you know if the liner is 'all the way up' and if its not, how do you get it there?
interesting read! cheersDo you mean all the way down? The battering of the fire ring cos the liner moves then leaves a non sealing access to the coolant..

Before I bought a P38 I was tracking this on EBay. There seemed to be the same few that always cropped up when searching. The enthusiast cars circa £5k used to go quickly. Anything £2-3k hung round as they often had significant issues.So, I bought my first P38 today.
Horray.
I took a chance and went with a blind bid on eBay. To cut a long story short it overheated 10 minutes into my journey home.
Booooooo.
Limped to a garage who added some water to the header tank and there was clearly bubbles being forced into the system.
So, head gasket or slipped liners. Bummer.
Previous owner was good enough to let me return it. We got chatting and he offered to to transport it to my place with a discount for me to get it fixed.
The car was otherwise quite nice so may not be the worst idea.
Trying to establish if it's worth it.
I can get an engine with a 30 day warranty off eBay for £800 delivered on an exchange basis.
Has anybody got any experience swapping the V8 over in a p38?
Looks to be plenty of room in there and not too much in the way. I think my engine crane would reach.
I would want it swapped quickly however as I already have too many projects so would only be interested if it's a fairly straightforward swap.
Any thoughts on the value of a P38 with a knackered engine to establish a fair discount?
Here is the car

(I'll send the thread to the previous owner so he can decide what he wants to do)
Thanks all
My P38 head gasket seems to be leaking gas into the cooling system, after an overheating event. No white smoke, no oil in the coolant and no coolant in the oil. The header tank does not smell of exhaust fumes at all. I got a RELD test kit, blue dye turned yellow in 2 minutes, confirming exhaust fumes in the coolant. But zero smell. Defo generating gas into the cooling system though - bleed the radiator, go for a run, then find more air / gas in the rad. I guess it's time to check the plugs for contamination / pressure test / compression check etc. But am surprised that there is no "fumes" smell. Thoughts and opinions on this would be greatly appreciated.Sniff test is quick and cheap.

I'll check for drips - good point.Might just be going down the exhaust, is there moisture coming out the tailpipe? condensation unusual this time
of year, are you losing coolant?
…and check for the problem I had - blocked rad bleed pipe into the header tank. Ring UV tracer dye too.Simple answer, not difficult, but quite time consuming. Personally I’d try other routes first, rad , thermostat, then heads . Best of luck
Have you got a pressure tester¿ best way to check for leaks with a cold engine or the fan to blow it all awayI'll check for drips - good point.
