Problem piston

I am still in need of a measuring device, but it seems as if the other piston's squish pads are slightly shorter. I will measure them and have the height differences corrected.


You would be safe if you remove the entire squish pad. The pistons seem to be flush in the block on the pictures and only squish pads are above deck.

That is correct. I'm just a little concerned about how it will run with out them


The EG motors ran without them and had no issues. It will drop your compression a tiny bit, but that can be calculated once measured.

I always have felt that the CR was a little high, the car pinged quite badly at lower altitudes and I ran much slower ignition timing than before. Last time I set the timing to 3° and its still pinging. Anything lower and the power dropped dramatically.

So now I have a plan.

Cut it down and let pistons sit flush in the block. Pinging problem would be gone then and you can set timing back to normal.

I think that's exactly what I should do.

Did you manage to get the squish pads cut down on the pistons?

Yes. I went ghetto all over the squish pads and filed them down with a flat file. Turns out that the heat exchanger was the cause of my issue with the oil and water mixing. Went back to no heat exchanger.

I can be grateful that I opened the motor so I could solve the piston clearance issue.

So no more pinging on motor and timing.

No still pinging closer to the coast, but much better otherwise

OK so long time since my last update and there has been some changes, first was that I finally solved an issue that's been plaguing me for quite some time that was gradually getting worse. When it reached its peak the car was actually cutting out from fuel starvation. I have managed to solve it to the largest extent by running an electric fuel pump directly to the carb. The previous carb also decided to give up on life and has been replaced with a Dorco brand replacement part.

The second part was the final part I have been wanting for my car since before I changed the engine, I now have a free flow exhaust and I am super stoked with the results. Here are some picsImageImageImage

Well done on solving the gremlins and that free flow must have helped a bit with better pull on the motor to get the gasses out.

Getting the motor the correct amount of fuel has made the most difference.

Took a little time off work this last week and went up to Springs to spend time with some close friends. R1000 fuel and 1023km travelled hassle free. Car ran smooth at the Highfeld, very pleased over all.Image
