Started tackling the oil leak today. On inspection I saw that the left valve cover was pushed upwards, probably happened when I pushed the spring in place.

I also took down the starter motor hoping to find a reason for it squealing a bit when the engine starts but I couldnt find anything. I put the starter in my vice and hooked it up to a spare battery and it runs flawlessly.

Here's a clip of benchtesting the starter.

Here's a clip of the engine start efter putting the starter back on the car.

Any ideas on how to fix the annoying squealing noise?

Squealing noise turns out to probably be the throwout bearing.....I'll need to tackle that before tuning I think.

The last few weeks has been spend fixing issues found after getting the engine to start reliably. The biggest hurdle was the throwout bearing. Last weekend the gearbox came out and I ordered a new throwout bearing and all the associated small parts.

While waiting for the parts to arrive i cleaned up the seats. They need to be recovered eventually but for now the California patinated cracked and torn vinyl will have to do. This passenger seat is the better of the two.

I also cadded up some baseplates for the new velocity stacks and had them lasercut at work. A good friend of mine got them welded up tonight.

For my birthday earlier this week I also had a package arrive that I ordered about a month ago. Two custom front mats with the Martini Racing colours.

I'm really happy for you Mats. You've given that car quite a beautiful transformation so far. It looks like you'll have it all wrapped-up by summer and be enjoying it with the top down when the warm weather gets there. :mrgreen:

About due for a bit of an update here....

Had the car back together for a booked dyno tuning day on May 9th. Long story short, Engine started puking oil from the passenger side valve cover and making a bad noise around 5000 rpm. I've been happier....

Oil seemed fine but a leakdown test showed 40% leakage on the #3 cylinder. Since I could not find the source of the noise I bit the bullet and shipped out my spare 1.7 Engine to GBOT in Denmark for a 78x96 build.
New engine should be done sometime in august.

Thanks Nate! :)

Apprently the gearbox input shaft seal took offence to having to start to work again and sprung a leak so 48 hours after the dyno I had to take the gearbox out of the car. Waiting for a new seal now.
