Sc12 Supercharged Small Bore - Teeth in the oil
Turbo Mini Forums

Not happy to disagree with the experts but I have breathers on timing cover, rocker box and distributor hole (the latter with a Moroso non return can) and all I ever get in the catch tank is water vapour.

I think the point about coolant & oil temp is very much on the money. Especially as you are introducing moisture by virtue of the WI. The breathers also need to be able to breathe, via a catch can, but with some way of allowing the moisture to get out.

Totally agree on getting engine warm enough.
Not a problem with my driving style.

I think it filled with water and then started to pull oil out as everything blocked up.

I'm away at the no but I have left the stuff to settle to see the ratio of water to oil.

A hotter stat and some changes to the breathers to introduce a pcv via a catch tanks and then some testing was going to be my next steps.

Thanks for all of the advice so far.

Well hopefully do some testing tomorrow afternoon in the meantime, one of the guys on the mk1 forum took a load of great pics, and one of my car, popping a small wheelie, not bad for a car with hydro suspension

Well the brake pads are shot on the drivers side where they have been contaminated with oil.
I went out for a spin and as soon as I touched the brakes the car pulled hard left. Took it back and found the oil on the pads...
Shame as they were mintex 1144's so, will need to order some more.
Can you use the carbon metallic with the kad 4-pots?

Ok new brake pads installed and I have plumbed in a new baffled catch tank that takes one line from the rocker box and one from the crank case. The output is via a pcv valve and is connected to the air filter.

Should I run it with a vented or non vented oil filler cap?

Ok so it made it to Brighton and back, it ran very well. The new catch tank, and breather back to the airfilter seems to be running well too.

I was worried about residue in the inlet but after a good 650mile nothing.

I think all the comments about temp are very true, with the warmer temps 16+ dog there seemed to be much less meyo stuff.

I have found nothing in the catch tank and the it only used about 1/2 a pint in all 650 miles and I wasn't hanging about going down or back!

So far a happy chap, thanks all for the help.

Nice one Graham !

doing well mate
are you still using those spring things they put in place of the rea shocks or something different

my car was hydro but one of the bags started leaking so not being able to find a replacement for a good price i just went to cones

Hi, no its on Hydro... with the "competition" bump stops front and rear (I thought these were a good idea to help protect from a bag failure). with the suspension now all pointing in the correct direction (thanks to the setting that WilH gave me)... and a rear ARB.

I also found front an rear tyre pressures make a big difference.

I must admit the car feels great now..

I went out to the car tonight, to give it the car a look over as I might be going Combe..

The water injection nozzle was blocked again. I stripped the nozzle as I couldn't see anything, the car has been stood a few months, I'm thinking of making a purge so that I can empty the lines once its ready to be stood for a while.

Could be corrosion deposit...... What metals are in contact with the water/ meth mix? Nozzle, fittings etc......

How strong a meth/water mix are you running ? The meth is corrosive.

A firend of mine runs 100% meth. Hasn't had any issues with his system

I have tried two different nozzles, brass and a stainless nickle plated job, both do it, even if it's straight water. I think the nozzle is small so the block with gunk let alone a particle. A strip down sorts it, I think I will setup a little purge system so I can blow the line through when it stands

Can't you just blow the air line down it?

If I had one😀

I had a good look at your car at blyton this year graham and i was very impressed with the build and how it went, well done.
I had the blue turbo clubby. I really enjoyed the whole weekend (apart from the ice on my tent in the morning). I was happy that my car didnt let me down apart from loosening manifold nuts.

Thanks for the kind words, however, I must admit your clubby was spotless, and it went like a missile! I was very impressed.

Thanks Graham. To be honest I was supprissed myself of how it went, not so much the power more the way it handled and I was able to use it on a high boost setting without it squirming all over the place. I was using avonbars new ultimate ph3 cam which liked to rev but i feel it would be more suited for a gt20. It's a great track for minis. On the Sunday I had a good go with one of those bike engined striker cars for a good 8 laps until I ran out of breaks and more likely talent on the bend near the start and finish which was great amusement for the crowd.

It did look on the track. Very very quick.

Ok cock, was doing some basic checks and I started the car and it smoked a bit. I warmed it up a little and then changed the oil and found a chunk of tooth and a fury sump plug ☹️

What’s the tooth? Looks like a synchro one, can’t remember the technical term!
