Well log story short,
friday i set off to the mot station and i got possibly half a mile away from my house,
gave it some boost in 2nd gear and didn't watch the boost gauge,
pulled up the a roundabout and cough cough cough yup running on 3 cylinders and smoking worse than ever with no power at all,
So drove it home at 40mph and a ozone killing cloud of smoke behind me.
compression, sparks and fuel all fine.....
So i blew the head gasket or a inlet gasket
Rather than mess about i stripped the engine down and this time going to build it properly rather than in 5 minutes
new turbo, piston rings, oil pump, liner seals, head gasket, head bolts, head skimmed and all the valves relapped in
the head has already had new guides by the looks of things and the valves look new too but it had a bend in the centre when checked with the straight edge so needed skimming
Got the head back from being skimmed today, and i've done the valve lapping
Spare cylinder head is screwed, det marks a plenty, corrosion pitting in the head and 3 or 4 valve seats beyond repair
few pics from the phone when stripping it down again
other pics currently uploading
