So in true last minute motorsport style, I had to remove the supercharger again as it was making noises still, stripped it down and put some more grease in the needle bearings and changed the oil to gearbox fluid and it was a lot quieter, not perfect but useable.
All set up for race day, cars running roughly 30bhp down so qualifying was always going to be tough against my fellow class B racers, managed 10th and 11th for the two races, killed a CV joint at the end of qualifying so pulled in
Race one and not the best start as got boxed in and lost a place to the mini but got it back a few corners later, into a great battle with the 1.8T 20v mk2 golf until another CV joint gave up retiring me from the race
Race two got a better start and again was into a good battle with the golf, he had me on the straights but I was all over him on the brakes and cornering, was just never close enough on the part I was a lot faster to put a move on him and get past safely. Yet another CV joint died ending my race, this time it spat the shaft out mid bend
Some others of the races
Back at the workshop on bank holiday Monday I decided to look over the car, as you can see I’ve done a proper job of the CV joint, it also took out the bottom link hose on the calliper. I decided to pull the whole lot out and check everything over as I just wasn’t happy with the engine, found my exhaust leak which was causing it to run a bit rich on the wideband, welded the crack back up.
Dropped the oil and found a sump plug full of bearing liner, despite no knocking noise this is obviously a knock on effect from when the oil hose popped off at donnington Park. Stripped all the parts off the old engine I’m keeping and gave them a good clean through in the parts washer.
Made a new magnetic sump plug using a drilled out standard one. Stripped both engines fully and started to build up when the dipstick tube snapped off leaving the bottom section in the sump still, thought I’d knock it down and use a magnet to get it out the sump plug hole but it bottomed out in the tube recess so had to make a tool to pull it back out as it was late and I really didn’t want to have to take the sump off
Will finish it off tomorrow.
So the CV failure is a mix of the cheap CV grease burning off and drying out the joint and excessive engine/gearbox movement. So I’ve ordered some high temp grease and some two part polyurethane mix to poor into the mounts as the old sikaflex was just not up to the job anymore, ripped it all out and de greased them ready.
