This is how the story goes...
Driving down a country lane, with 2 cars in front... I'm in third gear and the road opens out. I put my foot down to overtake the first car. I pulled level, had my foot fully down and on full boost there was but too much power, as had a little wheels spin! I lifted off a tad, power back on and the car popped out of 3rd gear and BANG ... Looked in the rear view mirror to see white smoke pouring out the exhaust and I lost power. Coasted to a layby and started crying (not really).
Car would crank over but not fire... Opened the bonnet and had a load of oil over rad fan and over the front left of the engine (by the water pump) and had lost half a litre of water. I topped up the water and check the oil. After 10mins, I got the car to start up but ran very lumpy. I nursed it to my uncles house about 2miles, at 30mph and smoking badly . Once car warmed up, the white smoke got worse but was at my destination!
I had turned the boost down a little from 20psi to 16, ARF was bang on 12.1 (at 16psi) but did get a little boost spike and would leaned out, for second or so. i recon I have done damage because of over-fuelling or over revving? Revlimiter set to 7k, don't know what can I got!
Plan:
· Order up gasket set (I hope just the head gasket is needed but just in case) and head bolts before weekend - What gasket sets do people recommend? Where from? and how much?
· Take off head on Saturday morning. Will be done in Princes Risborough if anyone is about?
· Assess damage and order bits if needed. I got my old engine that has been sat in the garden for nearly a year, don't know if I can use this as water has gone down the inlet manifold (no carb). Also got loads go spare bits but want to build it to last.
· Get car on the road ASAP!
Diagnosis so far based on hearsay (one of the below):
1. Head gasket
2. dropped valve
3. Piston/bottom end damage
Anyone got anymore to add to the list of 'what could be wrong' or 'why it happened'? Correct answers will win the original Group A cork as featured in the 300bhp beast!
