Picco P2 .26 Revo Problem

[atom3624]

I mentioned in another thread I'd replaced the TRX 3.3 in my Revo with the Picco P2 .26 and had encountered some problems - loose head screws, thus head after running fast.
I now notice the engine will warm up, run very well, then start to fume from around the head, and die. I cannot re-start.
When I remove the plug, I find the new plug - used for 10 minutes - doesn't glow and needs replacing.
I'm trying Traxxas' super duty long glow plug and OS#8 - the only ones I have to hand.

1. Is it possible / probable the head is warped - exaggerated when hot ?
2. Why are the plugs dying ? I'm now on my 6th plug this weekend - it runs fine, but I believe once I take it out and bring up to temperature, the same will happen again. It'll start losing power, there'll be some sign of fumes coming from between the crankcase and the cooling head, it'll stop, I won't be able to start it again and then find the plug needs replacing, AGAIN !!
3. Is there a simple answer like change the plug - which one ?

Can somebody please help with advice ?
Many thanks.

Don't know if this makes sense but I may have located a couple of problems :
1. I had a Trinity tuned exhaust on and this may have been part of the exhaust gas leak - replaced with the bolt-on standard and seems OK.
2. Tuning the engine isn't that difficult, but I have an Integy 3-shoe clutch hop-up which appears to be catching. I can't get a stable static idle - it edges forward.
I shall let everything cool down and open up the clutch during the week. May need to revery to the normal clutch.
Perhaps the leaking exhaust gases contributed to the glow plug problem ?

Quick update :
Since I replaced with the stock exhaust, the plugs have stopped blowing - obviously the leak was more with the exhaust than the head, and overheated them.
When I removed the engine, I opened the clutch - eventually - to find the Integy 3-piece pretty well disintegrated, with slivvers of aluminium coating the bell !!
Fortunately I had a spare MIP clutch, which I installed on the original flywheel I had kept.

Engine fires up fine, but is way out of tune - this will take time.
I also took the opportunity to better-align the carburettor, getting a smoother open / close of the throttle, and also it opens fully - didn't before.
I do find it's difficult to find the optimum position for the carb to be actuated smoothly 'though.

I'll put it down to a 'learning experience'. The MIP clutch seems fine - opened up again to check - no problems. Problem is just the tuning . . . . next weekend.:)
