I'm not goin to get into the story behind it but the head on the integrale has been damaged by a stray bolt getting thru the inlet manifold into no. 3 cylinder.
3 valves are bent and the piston is shot. The head has a few marks in it but with a bit of sanding i'm sure it could be smoothed out fairly well. Are high spots in the head really as dangerous to a turbo lump as they say? How important would the change in combustion chamber volume be?Oops. Might be easier to get a different head. Is it a 16v integrale? If so, the head from the Thema V.I.S. would do nicely as they flow very well. Wonder if the V.I.S. inlet manifold could also be fitted to aid low-end torque to offset turbo lag...hmm let's not make it less reliable now shall we (the bearings tend to sieze)! Last time I looked (which was a while ago now) FL Autos had a VIS in stock with only 24k miles on the clock. The phone number's in my previous Lancia related post.
This would go nicely with it too and what a bargain:
no, but spikey bits that can get hot could be, a little dressing and it will be ok.
How
Since its unlikely to be the same volume on all anyway I wouldnt worry!
I'm keeping it standard thanks very much! Well, with the exception of a few silicone hoses
Right, good enough for me :) Ordered the rest of the parts now so fingers crossed it gets running this time...
Just how does a bolt get into a running motor anyway??? How did it sound! Make sure nothing is cracked...
Sounds like the filter cover was off, and something small and removed got sucked in because it wasn't moved far enough away. Although how it got past the turbo/intercooler really confuses me.
It was a 4mm allen bolt of unknown origin. Our guess is it slipped into the inlet manifold when it was getting reassembled and worked its way down thru the valves because it ran for a bit before the noise came into it. It sounded like hitting a biscuit tin full of spanners with a frying pan, i got scared.
Once had a bolt come loose on the carb on the Volvo 340. Dropped into the butterfly and made a terrific racket and robbed all the power, which made me stop and have a look before it got in. And my dad once had a SAAB 99 with an unfindable rattle. Until the nut in one of the cylinders wore a hole in the piston.
Now holes in pistons I am very familiar with! I used to keep a collection to remind me why rich and retarded (nitrous) was best! I have melted plugs, lots of exhaust valves, pistons and a head... On one special occasion all at once! Too much too soon... Eventually you learn to see these things as a good excuse to fit better stronger parts!
LMAO you're as mad as Chet! one to many hits on the head as a child methinks
You are GW Bush and I claim my five pounds.
