I went away for a long weekend to the blue mountains and took the 560SEC. I've now got about 2,200km on it and it has performed well. There is plenty of power up some of those long sweeping turns near the top of bells line of road. The new tyres and wheels no longer shudder at speed and the engine is very smooth.
short term on the list to fix is the transmission leak, which is hopefully an o-ring in the bowden cable attachment.
Today my job is to replace the dented lower pan...
I took off the lower pan, and as expected I found a piece of broken guide in there. One of the guides was broken when I had the chain done a few months back.
What I didn't expect was to find a large lipped washer.
Does anyone know what it is?
There was no gasket on the pan, just some black sealer that wasn't sealing all that well.
There was also some small pieces of broken black plastic.
From what I can see, no damage from the dented pan?
Engine looks suspiciously clean. I wonder if it has been out? Engine number matches data card.
as I started cleaning the surfaces, I also notice there has been scoring on the upper pan, you can see to the right hand side of the oil pump as you're standing in front of the car and rear of oil pump.
I wonder how that got there?
I must say I’ve seen all sorts of chassis dyno results over the years & most I take with a grain of salt. They either seem far too high or too low & never what I’d expect to see. Too many variables so it seems. As a result I only trust engine dynos since there’s no error via tyres/diff/trans/torque convertor.
However it’s definitely a good idea to get a baseline & try to improve things from there. Personally I’d ditch the kidneys & do for a custom zorst!
Go for high flow aftermarket CATs since they work & they’re affordable. Delete excessive mufflers & bends. Only use flanges & no slip joints. A twin 2.5” with a correctly designed balance pipe should do the trick. Forget aftermarket exhaust valves since they’re illegal in most states (along with CAT delete).
