The car had been setup in Dec by Sitech and was flying on the standard T3 but got smokey after ragging it on the track about a week later.

Rebuilt the head in Jan as a precaution and fitted new Ford gasket, in hindsight should have skimmed head and decked the block then.

After that went up to Sitech again for a check over to see if things were good and they were but new turbo required which they fitted on Sat morning before the track day. Simon took it for a run and said everyhting seemed ok and the engine had been proven to be very strong before. Dunno what he did as I never went with him on the run but he did mention that he turned the boost up.

Drove it 100 miles home and went very well but at idle the oil light was flickering and seemed like it wanted to cut out. Noticed there was oil spilled at the corner of the rocker by the filler cap and so replaced the cap with a new one thinking that perhaps the increase in boost was lifting the cap.

On Sun morning waiting to get into the track the oil light flickered again and cut out at idle and would not start without a jump so perhaps the starter wiring is showing its age but was never a problem before the new turbo was fitted . I turned the idle speed up to 950 ish which stopped the oil light flicking and left it running with the fan swtiched on and the temp gauge read at the bottom of the normal (as usual) so everything seemed ok.

Ran a couple of warm up laps and after the green flag I went for it but the power was not there like before and felt progressively slower so pulled into pits and it began knocking slightly and the rest you know. Simon was there on the day and mentioned that the cooling system could have over pressurised hence the result.

Tried starting later once back at the garage and the starter relay just clicked away so its parked up waiting to be stripped, cheeRS.
