Just to clarify recent speculation, I am not a venga boy!
Been cleaning out the garage, memories :-(
Anyways, cars not been running perfectly recently, seems fine on WOT or any throttle for that matter, but at a static throttle position, say 3k rpm it seemed to be lumpy. May have been a few things, lambda and cat being my main concern.
With 274bhp the sports cat wasn't going to last long. Off to Hi-Q in town, it's only a piece of steel so what could go wrong?
Well, despite it being booked in for two weeks, no parts in stock to do it. Luckily I was working away that week so could drop the car off on the way in to work and leave it a few days.
Ktec sports cat cut in half with new flange welded to it so it can be fitted and refitted easily for MOT.
Then did a trackday at Bedford, did 30 or so pretty rapid laps, I fell in love with it again. Handled alright with the £500 suspension and flew up the straights rather rapidly. Took Sam from TDF out for a few laps, blasting down the main straight and boom, couldn't see anything behind me through the smoke. Guessed at a blown engine but it was still ticking over, gave it some throttle on the way to the pits and all seemed fine but went in anyway.
Under boost, it had started pushing oil out of the breather plate on top of the rocker. I'd never filled the 1mm hole so it was pressurising it. Onto the trailer and home, in a very good mood after how it had performed.
Dumped the car on the drive last week and opened the bonnet last night, started removing bits to have a look. Im fairly sure it's just pissing out of the breather plate so will fill the hole and re-seal it and have a look if it fixes it. The smoke was merely where it lands on the hot exhaust manifold
But yesterday I bought a new road race bike, so time and money is now going on a John O'grotes to Lands End bike ride, bad times. Could have forged the engine for the same money!!
