Well I haven't really EVER had a problem with my punto, and she's now done 97k miles, so she's done pretty well all things considered
last couple of days I've noticed it running a bit tappetty, but nothing a car of her age shouldn't come to expect.
however 2days back, it detoriated BADLY, sound'd like a tractor, tappety as a ford OHV pushrod motor, yet still driving smoothly (apart from low torque at idle) and normal fuel consumption.
no oil consumption
no dirtying of coolant fluids
normal running temps
however it has been warming up quicker than normal.
car is a '98 mk1 1.2 8v running on the std spi stuff again, 97k,
car is now off the road, and head is sitting in my front room.
it ain't pretty. there is NO cracks, however cyl 3 is black'ned and sooty, wheras the other cylinders look lean and dry.
just putting some water down the inlet/exhaust mani's cyl 1/2/4 managed to hold their water pretty much indefantly, but cyl 3 was pishing out of the inlet, (can't remember whether it was exh, or inlet now).
head looks like that. cyl 1 (cam belt end) on the right, cyl 4 on the left.
cam looks odd, its the 998 75mpi jobby, was correctly shimmed at the time by a bloke I know who works at ford Msport.
cam looks like theres been some valve bounce maybe? as it kind of stutters on the softer end of the profile
ANYBODY any ideas. I obviously need to skim it again now, and gonna rebuild the whole head, with maybe new valves and that (fairly cheap), do you reckon the valve seats have stuffed it, or maybe just some dirt in the valve seat/melted valve?
also got a video to post of the tappety'nesss
